• Question 156:

  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.

  

  During routine maintenance, it became necessary to shut down the GigabitEthernet1/0/1 interface on DSW1. All other interfaces were up. During this time, DSW1 remained the active device for the VLAN 102 HSRP group. You have determined that there is an issue with the decrement value in the track command for the VLAN 102 HSRP group. What needs to be done to make the group function properly?

  A. The decrement value on DSW1 should be greaterthan 5 and less than 15. 0
  B. The decrement value on DSW1 should be greaterthan 9 and less than 15.
  C. The decrement value on DSW1 should be greaterthan 11 and less than 19.
  D. The decrement value on DSWTs should be greaterthan 190 and less than 200.
  E. The decrement value on DSWTs should be greaterthan 195 and less than 205.
  C. The decrement value on DSW1 should be greaterthan 11 and less than 19.

• Question 157:

  An engineer is configuring an EtherChannel between two switches using LACP. If the EtherChannel mode on switch 1 is configured to active, which two modes on switch 2 establish an operational EtherChannel? (Choose two.)

  A. active
  B. auto
  C. desirable
  D. on
  E. passive
  A. active
  E. passive

• Question 158:

  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?

  A. Modify the spanning-tree priorities to dictate the traffic flow.
  B. Create a Layer 3 transit VLAN to segment the traffic between the sites.
  C. Use VTP pruning on the trunk interfaces.
  D. Configure manual trunk pruning between the two locations.
  C. Use VTP pruning on the trunk interfaces.

• Question 159:

  On which layer does IP source guard provide filtering to prevent a malicious host from impersonating the IP address of a legitimate host?

  A. Layer 1
  B. Layer 2
  C. Layer 3
  D. Layer 7
  B. Layer 2

• Question 160:

  What is the default HSRP priority?

  A. 50
  B. 100
  C. 120
  D. 1024
  B. 100
