Implementing Cisco IP Switched Networks

Question No: 71

A switch is added into the production network to increase port capacity. A network engineer is configuring the switch for DHCP snooping and IP Source Guard, but is unable to configure ip verify source under several of the interfaces. Which option is the cause of the problem?

  1. The local DHCP server is disabled prior to enabling IP Source Guard.

  2. The interfaces are configured as Layer 3 using the no switchport command.

  3. No VLANs exist on the switch and/or the switch is configured in VTP transparent mode.

  4. The switch is configured for sdm prefer routing as the switched database management template.

  5. The configured SVIs on the switch have been removed for the associated interfaces.

Answer: B

Question No: 72

A network engineer is extending a LAN segment between two geographically separated data centers. Which enhancement to a spanning-tree design prevents unnecessary traffic from crossing the extended LAN segment?

  1. Modify the spanning-tree priorities to dictate the traffic flow.

  2. Create a Layer 3 transit VLAN to segment the traffic between the sites.

  3. Use VTP pruning on thetrunk interfaces.

  4. Configure manual trunk pruning between the two locations.

Answer: C

Question No: 73

Refer to the exhibit

***Exhibitis Missing***

A network engineer deployed an older switch with the same spanning-tree priority as the existing root, which caused a network outage. In which two locations should the Spanning Tree protocol root guard feature be implemented? (Choose two.)

  1. On the designated root switch downlinks to the access layer.

  2. On all of non-root switch facing ports of the access layer

  3. On the access layers root facing ports

  4. On Layer 3 boundaries in the distribution layer

  5. Globally on all network switches.

Answer: A,B

Question No: 74

Interface FastEthernet0/1 is configured as a trunk interface that allows all VLANs. This command is configured globally:

monitor session 2 filtervlan 1 – 8, 39, 52

What is the result of the implemented command?

  1. All VLAN traffic is sent to the SPAN destination interface.

  2. Traffic from VLAN 4 is not sent to the SPAN destination interface.

  3. Filtering a trunked SPAN port effectively disablesSPAN operations for all VLANs.

  4. The trunk#39;s native VLAN must be changed to something other than VLAN 1.

  5. Traffic from VLANs 1 to 8, 39, and 52 is replicated to the SPAN destination port.

Answer: E

Question No: 75

Ferris Plastics, Inc. is a medium sized company, with an enterprise network (access, distribution and core switches) that provides LAN connectivity from user PCs to corporate servers. The distribution switches areconfigured to use HSRP to provide a high availability solution.

  • DSW1 -primary device for VLAN 101 VLAN 102 and VLAN 105

  • DSW2 – primary device for VLAN 103 and VLAN 104

  • A failure of GigabitEthemet1/0/1 on primary device should cause the primary device to release its status as the primary device, unless GigabitEthernet1/0/1 on backup device has also failed.

    Troubleshooting has identified several issues. Currently all interfaces are up. Using the running configurations and show commands, you have been asked to investigate and respond to the following question.

    During routine maintenance, GigabitEthernet1/0/1 on DSW1 was shut down. All other interfaces were up. DSW2 became the active HSRP device for VLAN 101 as desired. However, afterGigabitEthemet1/0/1 on DSW1 was reactivated, DSW1 did not become the active router for VLAN 101 as desired. What needs to be done to make the group for VLAN 101 function properly?

    1. Enable preempt in the VLAN 101 HSRP group on DSW1.

    2. Disable preempt inthe VLAN 101 HSRP group on DSW2#39;s.

    3. In the VLAN 101 HSRP group on DSW1, decrease the priority value to avaluethatis less #39; than the priority value configured in the VLAN 101 HSRP group on DSW2.

    4. Decrease the decrement value in the track command for the VLAN 101 HSRP group on U DSWTs to a values less than the value in the track command for the VLAN 101 HSRP group on DSW2.

    Which statement about using EtherChannel on Cisco IOS switches is true?

    1. A switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel. TheEtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 8 Gbps only for Gigabit EtherChannel.

    2. A switch can support up to 10 compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 1000 Mbps only for Fast EtherChannel or 8 Gbps only for Gigabit EtherChannel.

    3. A switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 16 Gbps only for Gigabit EtherChannel.

    4. A switch can support up to 10 compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 1000 Mbps only for Fast EtherChannel or 10 Gbps only for Gigabit EtherChannel.

    Answer: A

    Question No: 79

    For client server failover purposes, the application server team has indicated that they must nothave the standard 30 second delay before their switchport enters a forwarding state. For their disaster recovery feature to operate successfully, they require the switchport to enter a forwarding state immediately. Which spanning-tree feature satisfies this requirement?

    1. Rapid Spanning-Tree

    2. Spanning-Tree Timers

    3. Spanning-Tree FastPort

    4. Spanning-Tree PortFast

    5. Spanning-Tree Fast Forward
