is constantly evolving and the most sought-after certifications have
just been updated keeping up with the demands of today’s networking
careers. Effective May 17, Learning @Cisco announces the updated CCNA
Routing and Switching Certifications meeting the needs of Cisco
customers -- your future employers. In response, we at the Cisco
Networking Academy are pleased to offer the CCNA R&S 6.0 Bridging
Course, which together with the CCNA R&S 5.X curriculum, is in full
alignment with the CCNA R&S Certification.</span></div>

networking fundamentals is an important objective for us, and our CCNA
R&S curriculum covers many topics beyond certification. However,
staying aligned with the latest certification is very much our priority
too. Effective today, your instructors have access to the English
version of the CCNA R&S 6.0 Bridging Course. Additional languages of
Arabic, Chinese, French, Portuguese, Russian, and Spanish will release
in July and August. Effective May 31, you will have access to a free
self-paced CCNA R&S 6.0 Bridging Course that covers the new
supplemental topics that are included in the new Certification Exams.</span></div>

Packets for a given source-destination host pair are guaranteed to take the same path, even if multiple paths are available. For example, given two paths to the same network, all packets for destination1 on that network go over the first path, all packets for destination2 on that network go over the second path, and so on. Per-destination load balancing is enabled by default when you start the router, and is the preferred load balancing for most situations.<o:p></o:p></span></span></div>
<div class="pb1body1" style="background-color: white; color: #333333; font-family: Arial, serif; font-size: 14px; line-height: 22.875px; margin: 0.75pt 0cm 4.5pt;">

It uses the round-robin method to determine which path each packet takes to the destination. With per-packet load balancing enabled, the router sends one packet for destination1 over the first path, the second packet for (the same) destination1 over the second path, and so on. Per-packet load balancing ensures balancing over multiple links.<o:p></o:p></span></span></div>
<div class="pb1body1" style="background-color: white; color: #333333; font-family: Arial, serif; font-size: 14px; line-height: 22.875px; margin: 0.75pt 0cm 4.5pt;">

This means that per-packet load balancing can introduce reordering of packets. This load balancing method would be inappropriate for certain types of data traffic (such as voice traffic over IP) that depend on packets arriving at the destination in sequence.<o:p></o:p></span></span></div>
<div class="pb1body1" style="background-color: white; color: #333333; font-family: Arial, serif; font-size: 14px; line-height: 22.875px; margin: 0.75pt 0cm 4.5pt;">

If the bulk of data passing through parallel links is for a single pair, per-destination load balancing overloads a single link while other links have very little traffic. Enabling per-packet load balancing allows you to use alternate paths to the same busy destination.<o:p></o:p></span></span></div>

Slaptijack reader Raj is looking
for a way to limit inbound traffic on his switch ports based on the
time of day. Specifically, he wants to restrict speed to 256 Kbps
between 9 AM and 9 PM, and allow up to 1 Mbps the rest of the day. I've
done something similar to this in the past, but with only one
restriction, not two. Hopefully, this configuration will work!<br />
<strong>Note:</strong> This post is based on the work of a previous post on Cisco Catalyst rate limiting. Although I know that this will work in some cases, it may not work in yours. In other words, your mileage may vary.<br />
<span id="more-5598"></span><br />
Raj, the key to time-based rate limiting is to use the time range
command built into IOS. In your case, we want to define the time range
from 9 AM to 9 PM:<br />
<pre><code class="block"><i><span style="color: red;">time-range DAILY-0900-2100
periodic daily 7:00 to 21:00</span></i></code></pre>
Next, we need our access lists:<br />
<pre><code class="block"><i><span style="color: red;">ip access-list extended ACL-0900-2100
permit ip any any time-range DAILY-0900-2100
ip access-list extended ACL_ALL_HOURS
permit ip any any</span></i></code></pre>
And now our class maps to define which traffic to match:<br />
<pre><code class="block"><i><span style="color: red;">class-map match-all 256K
match access-group name ACL-0900-2100
class-map match-all 1M
match access-group name ACL_ALL_HOURS</span></i></code></pre>
And finally, our policy map:<br />
<pre><code class="block"><i><span style="color: red;">policy-map POLICY-IN
class 256K
police 256000 8000 exceed-action drop
class 1M
police 1000000 12500 exceed-action drop</span></i></code></pre>
Put it all together, and it looks like this:<br />
<pre><code class="block"><i><span style="color: lime;">time-range DAILY-0900-2100
periodic daily 7:00 to 21:00
!
ip access-list extended ACL-0900-2100
permit ip any any time-range DAILY-0900-2100
ip access-list extended ACL_ALL_HOURS
permit ip any any
!
class-map match-all 256K
match access-group name ACL-0900-2100
class-map match-all 1M
match access-group name ACL_ALL_HOURS
!
policy-map POLICY-IN
class 256K
police 256000 8000 exceed-action drop
class 1M
police 1000000 12500 exceed-action drop</span></i></code></pre>

This particular configuration was done on a Cisco Catalyst 2960.<br />
<br />
As I mentioned, the key is QoS. The first thing you need to do is globally enable QoS with the <code>mls qos</code> configuration command. Once this command is enabled, QoS is enabled on all ports with default settings.<br />
Next, we'll need an access-list to match traffic on. In this
example, we are going to police all traffic coming through the switch
port, so our access-list will match all IP addresses.<br />
<pre><code class="block"><span style="color: red;"><i>ip access-list extended ACL_SLAP
permit ip any any</i></span></code></pre>
<br />
A class map is necessary to classify our traffic. <br />
<pre><code class="block"><span style="color: red;"><i>class-map match-all CLASS_SLAP
match access-group name ACL_SLAP</i></span></code></pre>
<br />
The policy map dictates what we want done to the traffic class previously defined. The <code>police</code>
configuration command sets our rate limit in this example to 8 Mbps the
a burst size of 100 KB. The burst size is the trickiest part of this
command. If the burst is set too low, your traffic will not be able to
approach the maximum allowed throughput do to packet drops.<br />
Because <a href="http://slaptijack.com/system-administration/what-is-tcp-window-scaling/" title="What is TCP Window Scaling? | Slaptijack">TCP window scaling</a>
halves the window size for each dropped packet, it's important to set
the burst size at a level that doesn't impact performance. The rule of
thumb is that the burst size should be double the amount of traffic
sent at the maximum rate at a given round-trip time. In this example, I
assumed a round-trip time of 50 ms which results in a burst size of 100
KB.<br />
<pre><code class="block"><i><span style="color: red;">policy-map POLICY_SLAP
class CLASS_SLAP
police 8000000 100000 exceed-action drop</span></i></code></pre>
<br />
Finally, apply the policy-map to the switch port with the <code>service-policy</code> configuration command.<br />
<pre><code class="block"><span style="color: red;"><i>interface GigabitEthernet0/2
service-policy input POLICY_SLAP</i></span></code></pre>
<br />
And now you're done. In our example, we configured a switch port to
only allow inbound traffic at 8 Mbps. We won't be able to truly max the
8 Mbps, but we should come close.<br />
<br />
This is the full text rate limiting example<br />
<pre><code class="block"><i><b><span style="color: lime;">mls qos
ip access-list extended ACL_SLAP
permit ip any any
class-map match-all CLASS_SLAP

<br />
We have a router, f0/0 will be for the Internet connection with bandwidth of 30Mbps.<br />
Its f0/1 will be connected to a switch for internal networks.<br />
This link will be separated to 3 VLANs for 3 internal networks.<br />
Is there is a way to guarantee 10Mbps for each VLAN but allow use up to 30Mbps when another two VLANs are not using any Internet bandwidth?<br />
We worry about download bandwidth from internet.<br />
<br />
The 3 internal networks will all have public IPs and they belong to their own subnets. There won't be NAT/PAT. Is there a sample config. available?<br />
<br />
The following example polices the inside interface to 30Mbps. It also utilizes a fair queue mechanism so that all subnets are queued equally yet can use the entire purchased rate in the absence of competing traffic.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

exit<br />
<br />
The parent policy (physical) limits the traffic to 30Mbps. The child policy (subnets) allocates 33% of available bandwidth to each subnet. In this case it should be very close to 10Mbps for each subnet. This is a fair queue mechanism so it will only enforce the 10Mbps limit if all subnets are in contention with each other. If subnet A and B are idle subnet C can take all 30Mbps.<br />
<br />
A it to the physical interface should affect all traffic traversing that interface; which includes all sub-interfaces. Please click here for an example.<br />

If this techniques doesn't support 1800 you could police each sub-interface. This would ensure good service for everyone but leave bandwidth unused and unavailable during idle times.<br />

<span style="font-size: large;">The spanning-tree port priority of each interface is at the default setting. The network administrator enters the spanning-tree vlan 1 root primary command on S4. What is the effect of the command?</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Spanning tree blocks Gi0/1 on S3.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">Gi0/2 on S3 transitions to a root port.</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Port priority makes Gi0/2 on S1 a root port.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>S4 is already the root bridge, so there are no port changes.<br />
<br />
<span style="font-size: large;">3.Which two statements are true about the default operation of STP in a Layer 2 switched environment that has redundant connections between switches? (Choose two.)</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>The root switch is the switch with the highest speed ports.<br />
<i><span style="color: red;"><span class="Apple-tab-span" style="white-space: pre;"> </span>Decisions on which port to block when two ports have equal cost depend on the port priority and identity.</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>All trunking ports are designated and not blocked.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Root switches have all ports set as root ports.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><span style="color: red;">Non-root switches each have only one root port.</span><br />
<br />
<span style="font-size: large;">4.What three link types have been defined for Rapid Spanning-Tree Protocol? (Choose three.)</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">shared</span></i><br />

<br />
<span style="font-size: large;">5.What two features of the Spanning-Tree Protocol contribute to the time it takes for a switched network to converge after a topology change occurs? (Choose two.)</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">the max-age timer</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>the spanning-tree hold down timer<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><span style="color: red;">the forward delay</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>the spanning-tree path cost<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>the blocking delay<br />
<br />
<span style="font-size: large;">6.What Rapid Spanning Tree Protocol (RSTP) role is assigned to the forwarding port elected for every Ethernet LAN segment that links two switches?</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>alternate<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>backup<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">designated</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>edge<br />
<br />
<span style="font-size: large;">7.How can a network administrator influence which STP switch becomes the root bridge?</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Configure all the interfaces on the switch as the static root ports.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Change the BPDU to a lower value than that of the other switches in the network.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Assign a lower IP address to the switch than that of the other switches in the network.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">Set the switch priority to a smaller value than that of the other switches in the network.</span></i><br />
<br />
<span style="font-size: large;">8.Which statement or set of paired statements correctly compares STP with RSTP?</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>STP and RSTP have the same BPDU format and flag field information.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>STP specifies backup ports. RSTP has only root ports, alternate ports, and designated ports.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>STP port states are independent of port roles. RSTP ties together the port state and port role.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">STP waits for the network to converge before placing ports into forwarding state. RSTP places designated ports into forwarding state immediately.</span></i><br />
<br />
<span style="font-size: large;">9.Which two statements describe the BIDs used in a spanning tree topology? (Choose two.)</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>They are sent out by the root bridge only after the inferior BPDUs are sent.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">They consist of a bridge priority and MAC address.</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Only the root bridge will send out a BID.<br />
<i><span style="color: red;"><span class="Apple-tab-span" style="white-space: pre;"> </span>They are used by the switches in a spanning tree topology to elect the root bridge.</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>The switch with the fastest processor will have the lowest BID.<br />
<br />
<span style="font-size: large;">10.In which STP state does a port record MAC addresses but not forward user data?</span><br />

<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">one root bridge per network</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>all non-designated ports forwarding<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><span style="color: red;">one root port per non-root bridge</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>multiple designated ports per segment<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>one designated port per network<br />
<br />
<span style="font-size: large;">12.Which two items are true regarding the spanning-tree portfast command? (Choose two.)</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">PortFast is Cisco proprietary.</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>PortFast can negatively effect DHCP services.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>PortFast is used to more quickly prevent and eliminate bridging loops.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Enabling PortFast on trunks that connect to other switches improves convergence.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">If an access port is configured with PortFast, it immediately transitions from a blocking to a forwarding state.</span></i><br />
<br />
<span style="font-size: large;">13.Refer to the exhibit.</span><br />

<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">The priority was statically configured to identify the root.</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>STP is disabled on this switch.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>The timers have been altered to reduce convergence time.<br />
<br />
<span style="font-size: large;">14.Which two criteria does a switch use to select the root bridge? (Choose two.)</span><br />
<i><span style="color: red;"><span class="Apple-tab-span" style="white-space: pre;"> </span>bridge priority</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>switching speed<br />

<span style="font-size: large;">Server sends an ARP request for the MAC address of its default gateway. If STP is not enabled, what will be the result of this ARP request?</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Router_1 will drop the broadcast and reply with the MAC address of the next hop router.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Switch_A will reply with the MAC address of the Router_1 E0 interface.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">Switch_A and Switch_B will continuously flood the message onto the network.</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>The message will cycle around the network until its TTL is exceeded.<br />
<br />
<span style="font-size: large;">16.Which three statements are accurate regarding RSTP and STP? (Choose three.)</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>RSTP uses a faster algorithm to determine root ports.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>RSTP introduced the extended system ID to allow for more than 4096 VLANs.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">Both RSTP and STP use the portfast command to allow ports to immediately transition to forwarding state.</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Like STP PortFast, an RSTP edge port that receives a BPDU loses its edge port status immediately and becomes a normal spanning-tree port.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">Configuration commands to establish primary and secondary root bridges are identical for STP and RSTP.</span></i><br />
<i><span style="color: red;"><span class="Apple-tab-span" style="white-space: pre;"> </span>Because of the format of the BPDU packet, RSTP is backward compatible with STP.</span></i><br />
<br />
<span style="font-size: large;">17.In which two ways is the information that is contained in BPDUs used by switches? (Choose two.)</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>to negotiate a trunk between switches<br />

<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">to identify the shortest path to the root bridge</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>to prevent loops by sharing bridging tables between connected switches<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">to determine which ports will forward frames as part of the spanning tree</span></i><br />
<br />
<span style="font-size: large;">18.Refer to the exhibit. </span><br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-dc81XfC-FBw/UAfUtGTN5SI/AAAAAAAAApA/0VBj34MTJH4/s1600/18.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-dc81XfC-FBw/UAfUtGTN5SI/AAAAAAAAApA/0VBj34MTJH4/s1600/18.jpg" /></a></div><span style="font-size: large;"><br />
</span><br />
<span style="font-size: large;">All switches in the network have empty MAC tables. STP has been disabled on the switches in the network. How will a broadcast frame that is sent by host PC1 be handled on the network?</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Switch SW1 will block the broadcast and drop the frame.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><i><span style="color: red;">Switch SW1 will forward the broadcast out all switch ports, except the originating port. This will generate an endless loop in the network.</span></i><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Switch SW1 will forward the broadcast out all switch ports, except the originating port. All hosts in the network will reply with a unicast frame sent to host PC1.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Switch SW1 will forward the traffic out all switch ports except the originating port as a unicast frame. All hosts in the network will reply with a unicast frame sent to switch SW1.<br />
<br />
<span style="font-size: large;">19.Which two actions does an RSTP edge port take if it receives a BPDU? (Choose two.)</span><br />

<span class="Apple-tab-span" style="white-space: pre;"> </span>VTP is only compatible with the 802.1Q standard.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>VTP adds to the complexity of managing a switched network.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>VTP allows a switch to be configured to belong to more than one VTP domain.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><span style="color: red;"><i>VTP dynamically communicates VLAN changes to all switches in the same VTP domain.</i></span><br />

<span style="font-size: large;">8.What are two characteristics of VLAN1 in a default switch configuration? (Choose two.)</span><br />
<br />
VLAN1 should renamed.<br />
<br />
<span style="color: red;">VLAN 1 is the management VLAN.</span><br />
<br />
<span style="color: red;">All switch ports are members of VLAN1.</span><br />
<br />
Only switch port 0/1 is assigned to VLAN1.<br />
<br />
Links between switches must be members of VLAN1.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">9.What switch port modes will allow a switch to successfully form a trunking link if the neighboring switch port is in "dynamic desirable" mode?</span><br />
<br />
dynamic desirable mode<br />
<br />

<span style="font-size: large;">Computer B is unable to communicate with computer D. What is the most likely cause of this problem?</span><br />
<br />
The link between the switches is up but not trunked.<br />
<br />
VLAN 3 is not an allowed VLAN to enter the trunk between the switches.<br />
<br />
The router is not properly configured to route traffic between the VLANs.<br />
<br />
<span style="color: red;">Computer D does not have a proper address for the VLAN 3 address space.</span><br />
<br />
<span style="font-size: large;">11.What statement about the 802.1q trunking protocol is true?</span><br />
<br />
802.1q is Cisco proprietary.<br />
<br />
802.1q frames are mapped to VLANs by MAC address.<br />
<br />
802.1q does NOT require the FCS of the original frame to be recalculated.<br />
<br />
<span style="color: red;">802.1q will not perform operations on frames that are forwarded out access ports.</span><br />

<span style="font-size: large;">Which two conclusions can be drawn regarding the switch that produced the output shown? (Choose two.)</span><br />
<br />
The network administrator configured VLANs 1002-1005.<br />
<br />
The VLANs are in the active state and are in the process of negotiating configuration parameters.<br />
<br />
A FDDI trunk has been configured on this switch.<br />
<br />
<span style="color: red;">The command switchport access vlan 20 was entered in interface configuration mode for Fast Ethernet interface 0/1.</span><br />
<br />
<span style="color: red;">Devices attached to ports fa0/5 through fa0/8 cannot communicate with devices attached to ports fa0/9 through fa0/12 without the use of a Layer 3 device.</span><br />

<span style="font-size: large;">Company HR is adding PC4, a specialized application workstation, to a new company office. The company will add a switch, S3, connected via a trunk link to S2, another switch. For security reasons the new PC will reside in the HR VLAN, VLAN 10. The new office will use the 172.17.11.0/24 subnet. After installation, users on PC1 are unable to access shares on PC4. What is the likely cause?</span><br />
<br />
The switch to switch connection must be configured as an access port to permit access to VLAN 10 on S3.<br />
<br />
The new PC is on a different subnet so Fa0/2 on S3 must be configured as a trunk port.<br />
<br />
<span style="color: red;">PC4 must use the same subnet as PC1.</span><br />
<br />
A single VLAN cannot span multiple switches.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">14.The network administrator wants to separate hosts in Building A into two VLANs numbered 20 and 30. Which two statements are true concerning VLAN configuration? (Choose two.)</span><br />
<br />
<span style="color: red;">The VLANs may be named.</span><br />
<br />
VLAN information is saved in the startup configuration.<br />
<br />
Non-default VLANs created manually must use the extended range VLAN numbers.<br />
<br />
<span style="color: red;">The network administrator may create the VLANs in either global configuration mode or VLAN database mode.</span><br />
<br />
Both VLANs may be named BUILDING_A to distinguish them from other VLANs in different geographical locations.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">15.Refer to the exhibit.</span><br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-Efcz3Wtk7ns/UAeHl79EcbI/AAAAAAAAAnI/9CzrQvCsAd4/s1600/15.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-Efcz3Wtk7ns/UAeHl79EcbI/AAAAAAAAAnI/9CzrQvCsAd4/s1600/15.jpg" /></a></div><br />
<span style="font-size: large;">The exhibited configurations do not allow the switches to form a trunk. What is the most likely cause of this problem?</span><br />
<br />
Cisco switches only support the ISL trunking protocol.<br />
<br />
<span style="color: red;">The trunk cannot be negotiated with both ends set to auto.</span><br />
<br />
By default, Switch1 will only allow VLAN 5 across the link.<br />
<br />
A common native VLAN should have been configured on the switches.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">16.What is the effect of the switchport mode dynamic desirable command?</span><br />
<br />
DTP cannot negotiate the trunk since the native VLAN is not the default VLAN.<br />
<br />
The remote connected interface cannot negotiate a trunk unless it is also configured as dynamic desirable.<br />
<br />
The connected devices dynamically determine when data for multiple VLANs must be transmitted across the link and bring the trunk up as needed.<br />
<br />
<span style="color: red;">A trunk link is formed if the remote connected device is configured with the switchport mode dynamic auto or switchport mode trunk commands.</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">17.Which two statements describe the benefits of VLANs? (Choose two.)</span><br />
<br />
VLANs improve network performance by regulating flow control and window size.<br />
<br />
VLANs enable switches to route packets to remote networks via VLAN ID filtering.<br />
<br />
VLANs reduce network cost by reducing the number of physical ports required on switches.<br />
<br />
<span style="color: red;">VLANs improve network security by isolating users that have access to sensitive data and applications.</span><br />
<br />
<span style="color: red;">VLANs divide a network into smaller logical networks, resulting in lower susceptibility to broadcast storms.</span><br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">18.What is a valid consideration for planning VLAN traffic across multiple switches?</span><br />
<br />
Configuring interswitch connections as trunks will cause all hosts on any VLAN to receive broadcasts from the other VLANs.<br />
<br />
<span style="color: red;">A trunk connection is affected by broadcast storms on any particular VLAN that is carried by that trunk.</span><br />
<br />
Restricting trunk connections between switches to a single VLAN will improve efficiency of port usage.<br />
<br />
Carrying all required VLANs on a single access port will ensure proper traffic separation.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">19.Which statement describes how hosts on VLANs communicate?</span><br />
<br />
Hosts on different VLANs use VTP to negotiate a trunk.<br />
<br />
<span style="color: red;">Hosts on different VLANs communicate through routers.</span><br />
<br />
Hosts on different VLANs should be in the same IP network.<br />
<br />
Hosts on different VLANs examine VLAN ID in the frame tagging to determine if the frame for their network.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">20.What happens to the member ports of a VLAN when the VLAN is deleted?</span><br />
<br />
<span style="color: red;">The ports cannot communicate with other ports.</span><br />
<br />
The ports default back to the management VLAN.<br />
<br />
The ports automatically become a part of VLAN1.<br />
<br />
The ports remain a part of that VLAN until the switch is rebooted. They then become members of the management VLAN.<br />
<br />
<span style="font-size: large;">21.Refer to the exhibit.</span><br />

<br />
The switch will request that the sending node resend the frame.<br />
<br />
The switch will issue an ARP request to confirm that the source exists.<br />
<br />
<span style="color: red;">The switch will map the source MAC address to the port on which it was received.</span><br />
<br />
The switch ends an acknowledgement frame to the source MAC of this incoming frame.<br />

<span style="font-size: large;">The exhibit shows partial output of the show running-config command. The enable password on this switch is "cisco." What can be determined from the output shown?</span><br />
<br />
The enable password is encrypted by default.<br />
<br />
An MD5 hashing algorithm was used on all encrypted passwords.<br />
<br />
<span style="color: red;">Any configured line mode passwords will be encrypted in this configuration.</span><br />
<br />
This line represents most secure privileged EXEC mode password possible.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">3.Which two statements are true about EXEC mode passwords? (Choose two.)</span><br />
<br />
The enable secret password command stores the configured password in plain text.<br />
<br />
<span style="color: red;">The enable secret password command provides better security than the enable password.</span><br />
<br />
<span style="color: red;">The enable password and enable secret password protect access to privileged EXEC mode.</span><br />
<br />
The service password-encryption command is required to encrypt the enable secret password.<br />
<br />
Best practices require both the enable password and enable secret password to be configured and used simultaneously.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">4.Which two statements about Layer 2 Ethernet switches are true? (Choose two.)</span><br />

<span style="font-size: large;">5.What happens when the transport input ssh command is entered on the switch vty lines?</span><br />
<br />
The SSH client on the switch is enabled.<br />
<br />
<span style="color: red;">Communication between the switch and remote users is encrypted.</span><br />
<br />
A username/password combination is no longer needed to establish a secure remote connection to the switch.<br />
<br />
The switch requires remote connections via proprietary client software.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">6.What are two ways to make a switch less vulnerable to attacks like MAC address flooding, CDP attacks, and Telnet attacks? (Choose two.)</span><br />

<span style="font-size: large;">What does the "2" stand for in the router ospf 2 statement?</span><br />
<br />
The number 2 is the autonomous system number.<br />
<br />
The number 2 indicates the number of networks advertised by OSPF.<br />
<br />
<span style="color: red;">The number 2 identifies this particular instance of OSPF on this router.</span><br />
<br />
The number 2 indicates the priority of the OSPF process on this router.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
<span style="font-size: large;">2.Router R1 is participating in the OSPF routing protocol as well as the EIGRP routing protocol. If R1 learns of network 192.168.10.0/24 from both the OSPF and internal EIGRP routing protocols, how will the route appear in the routing table of R1?</span><br />
<br />
Only the route learned from OSPF will appear in the routing table.<br />
<br />
<span style="color: red;">Only the route learned from EIGRP will appear in the routing table.</span><br />
<br />
Both routes will appear in the routing table and they will be used for load balancing.<br />
<br />
Neither route will appear in the routing table until the network administrator selects which one to use.<br />
