• Question 73:

  Which two options are two results of using the command spanning-tree vlan 50 root primary within a spanning-tree network under global configuration? (Choose two.)

  A. Spanning tree determines the priority of the current root for VLAN 50 and reduces the priority of the local switch to a lower value.

  C. The spanning-tree timers are reduced to improve the convergence time for VLAN 50.
  D. All ports that are configured on the current switch with VLAN 50 transition to designated ports.
  E. The switchport that is configured for VLAN 50 is the primary connection to the spanning- tree root switch.
  A. Spanning tree determines the priority of the current root for VLAN 50 and reduces the priority of the local switch to a lower value.
  D. All ports that are configured on the current switch with VLAN 50 transition to designated ports.

• Question 74:

  RSPAN has been configured on a Cisco Catalyst switch; however, traffic is not being replicated to the remote switch. Which type of misconfiguration is a cause?

  A. The RSPAN designated VLAN is missing the remote span command.
  B. The local and remote RSPAN switches are configured using different session IDs.
  C. The local RSPAN switch is replicating only Rx traffic to the remote switch.
  D. The local switch is overloaded with the amount of sourced traffic that must be replicated to the remote switch.
  A. The RSPAN designated VLAN is missing the remote span command.

• Question 75:

  A network engineer configured an Ethernet switch using these commands.

  Switchone(config) # Spanning-tree portfast bpdufilter default

  Which statement about the spanning-tree portfast feature on the switch is true?

  A. If an interface is enabled for portfast receives BDPU, the port goes through the spanning-tree listening, learning, and forwarding states.
  B. If an interface is enabled for portfast receives BDPU, the port does not go through the spanning-tree listening, learning, and forwarding states.
  C. If an interface is enabled for portfast receives BDPU, the port is shut down immediately.
  D. If an interface is enabled for portfast receives BDPU, the port goes into the spanning- tree inconsistent state.
  A. If an interface is enabled for portfast receives BDPU, the port goes through the spanning-tree listening, learning, and forwarding states.

• Question 76:

  Refer to the exhibit.

  

  Which configuration ensures that the Cisco Discovery Protocol packet update frequency sent from DSW1 to ALS1 is half of the default value?

  A. DSW1(config)#cdp timer 90
  B. DSW1(config-if)#cdp holdtime 60
  C. DSW1(config)#cdp timer 30
  D. DSW1(config)#cdp holdtime 90
  E. DSW1(config-if)#cdp holdtime 30
  F. DSW1(config-if)#cdp timer 60
  C. DSW1(config)#cdp timer 30

• Question 77:

  A network engineer must adjust the STP interface attributes to influence root port selection. Which two elements are used to accomplish this? (Choose two.)

  A. port-priority
  B. cost
  C. forward-timers
  D. link type
  E. root guard
  A. port-priority
  B. cost

• Question 78:

  Which statement about the use of SDM templates in a Cisco switch is true?

  A. SDM templates are used to configure system resources in the switch to optimize support for specific features, depending on how the switch is used in the network.
  B. SDM templates are used to create Layer 3 interfaces (switch virtual interfaces) to permit hosts in one VLAN to communicate with hosts in another VLAN.
  C. SDM templates are used to configure ACLs that protect networks and specific hosts from unnecessary or unwanted traffic.
  D. SDM templates are used to configure a set of ACLs that allows the users to manage the flow of traffic handled by the route processor.
  E. SDM templates are configured by accessing the switch using the web interface.
  A. SDM templates are used to configure system resources in the switch to optimize support for specific features, depending on how the switch is used in the network.

• Question 79:

  What is the effect of configuring the following command on a switch?

  Switch(config) # spanning-tree portfast bpdufilter default

  A. If BPDUs are received by a port configured for PortFast, then PortFast is disabled and the BPDUs are processed normally.
  B. If BPDUs are received by a port configured for PortFast, they are ignored and none are sent.
  C. If BPDUs are received by a port configured for PortFast, the port transitions to the forwarding state.
  D. The command enables BPDU filtering on all ports regardless of whether they are configured for BPDU filtering at the interface level.
  A. If BPDUs are received by a port configured for PortFast, then PortFast is disabled and the BPDUs are processed normally.

• Question 80:

  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 are configured 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.

  

  If GigabitEthemet1/0/1 on DSW2 is shutdown, what will be the resulting priority value of the VLAN 105 HSRP group on router DSW2?

  A. 90
  B. 100
  C. 150
  D. 200
  A. 90
