• Question 826:

  HSRP 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 HSRPto provide a high availability solution.

  -DSW1 -primary device for VLAN 101 VLAN 102 andVLAN 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.

  Use "show run" command to show. The left Vlan102 is console1 of DS1. Priority value is 200, we should decrement value in the track command from 11 to 18. Because 200 - 11 = 189 < 190 ( priority of Vlan102 on DS2 ).

• Question 827:

  A network engineer configured a fault-tolerance link on Gigabit Ethernet links G0/1, G0/2, G0/3, and G0/4 between two switches using Ethernet port-channel. Which action allows interface G0/1 to always actively forward traffic in the port-channel?

  A. Configure G0/1 as half duplex and G0/2 as full duplex.
  B. Configure LACP port-priority on G0/1 to 1.
  C. Configure LACP port-priority on G0/1 to 65535.
  D. LACP traffic goes through G0/4 because it is the highest interface ID.
  B. Configure LACP port-priority on G0/1 to 1.

  ---

  A LACP port priority is configured on each port using LACP. The port priority can be configured automatically or through the CLI. LACP uses the port priority with the port number to form the port identifier. The port priority determines which

  ports should be put in standby mode when there is a hardware limitation that prevents all compatible ports from aggregating. The higher the number, the lower the priority. The valid range is from 1 to 65535. The default is 32768.
