• Question 23:

  An EtherChannel bundle has been established between a Cisco switch and a corporate web server. The network administrator noticed that only one of the EtherChannel links is being utilized to reach the web server. What should be done on the Cisco switch to allow for better EtherChannel utilization to the corporate web server?

  A. Enable Cisco Express Forwarding to allow for more effective traffic sharing over the EtherChannel bundle.
  B. Adjust the EtherChannel load-balancing method based on destination IP addresses.
  C. Disable spanning tree on all interfaces that are participating in the EtherChannel bundle.
  D. Use link-state tracking to allow for improved load balancing of traffic upon link failure to the server.
  E. Adjust the EtherChannel load-balancing method based on source IP addresses.
  E. Adjust the EtherChannel load-balancing method based on source IP addresses.

• Question 24:

  For client server failover purposes, the application server team has indicated that they must not have 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?

  A. Rapid Spanning-Tree
  B. Spanning-Tree Timers
  C. Spanning-Tree FastPort
  D. Spanning-Tree PortFast
  E. Spanning-Tree Fast Forward
  D. Spanning-Tree PortFast

• Question 25:

  Refer to the exhibit.

  

  Why would the switch be considered as a root bridge?

  A. The bridge priority is 1 and all ports are forwarding.
  B. The switch priority for VLAN 1 and the macro specifies "This Bridge is the root".
  C. The bridge priority is 128.19 and all ports are forwarding.
  D. The switch priority value is zero, it has the lowest priority value for VLAN 1.
  D. The switch priority value is zero, it has the lowest priority value for VLAN 1.

• Question 26:

  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, 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, after GigabitEthemet1/0/1 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?

  A. Enable preempt in the VLAN 101 HSRP group on DSW1.
  B. Disable preempt in the VLAN 101 HSRP group on DSW2's.
  C. In the VLAN 101 HSRP group on DSW1, decrease the priority value to avaluethatis less ' than the priority value configured in the VLAN 101 HSRP group on DSW2.
  D. 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.
  A. Enable preempt in the VLAN 101 HSRP group on DSW1.

• Question 27:

  An access switch at a remote location is connected to the spanning-tree root with redundant uplinks. A network engineer notices that there are issues with the physical cabling of the current root port. The engineer decides to force the secondary link to be the desired forwarding root port.

  Which action accomplishes this task?

  A. Change the link-type to point-to-point.
  B. Enable Rapid Spanning Tree to converge using the secondary link.
  C. Adjust the secondary link to have a lower priority than the primary link.
  D. Apply a BPDU filter on the primary interface of the remote switches.
  C. Adjust the secondary link to have a lower priority than the primary link.

• Question 28:

  Refer to the exhibit.

  

  Switch A, B, and C are trunked together and have been properly configured for VTP. Switch C receives VLAN information from the VTP server Switch A, but Switch B does not receive any VLAN information. What is the most probable cause of this behavior?

  A. Switch B is configured in transparent mode.
  B. Switch B is configured with an access port to Switch A, while Switch C is configured with a trunk port to Switch B.
  C. The VTP revision number of the Switch B is higher than that of Switch A.
  D. The trunk between Switch A and Switch B is misconfigured.
  A. Switch B is configured in transparent mode.

• Question 29:

  A network engineer deployed a switch that operates the LAN base feature set and decides to use the SDM VLAN template. The SDM template is causing the CPU of the switch to spike during peak working hours. What is the root cause of this issue?

  A. The VLAN receives additional frames from neighboring switches.
  B. The SDM VLAN template causes the MAC address-table to overflow.
  C. The VLAN template disables routing in hardware.
  D. The switch needs to be rebooted before the SDM template takes effect.
  C. The VLAN template disables routing in hardware.

• Question 30:
