• Question 94:

  You have been asked to install and configure a new switch in a customer network. Use the console access to the existing and new switches to configure and verify correct device configuration.

  

  You are adding new VLANs. VLAN500 and VLAN600 to the topology in such way that you need to configure SW1 as primary root for VLAN 500 and secondary for VLAN 600 and SW2 as primary root for VLAN 600 and secondary for VLAN

  500. Which configuration step is valid?

  A. Configure VLAN 500 and VLAN 600 on both SW1 and SW2
  B. Configure VLAN 500 and VLAN 600 on SW1 only
  C. Configure VLAN 500 and VLAN 600 on SW2 only
  D. Configure VLAN 500 and VLAN 600 on SW1 ,SW2 and SW4
  E. On SW2; configure vtp mode as off and configure VLAN 500 and VLAN 600; configure back to vtp server mode.

• Question 95:

  After an EtherChannel is configured between two Cisco switches, interface port channel 1 is in the down/down state. Switch A is configured with channel-group 1 mode active, while Switch B is configured with channel-group 1 mode desirable. Why is the EtherChannel bundle not working?

  A. The switches are using mismatched EtherChannel negotiation modes.
  B. The switch ports are not configured in trunking mode.
  C. LACP priority must be configured on both switches.
  D. The channel group identifier must be different for Switch A and Switch B.
  A. The switches are using mismatched EtherChannel negotiation modes.

• Question 96:

  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 and DSW2. All other interfaces were up. During this time, DSW1 became the active router for the VLAN 104HSRP group. As related to the VLAN 104HSRP group, what can to be done to make the group function properly?

  A. On DSW1, disable preempt.
  B. On DSW2 decrease the priority value to a value less than 150.
  C. On DSW1, increase the decrement value in the track command to a value greater than 6.
  D. On DSW1, decrease the decrement value in the track command to a value less than 1.
  C. On DSW1, increase the decrement value in the track command to a value greater than 6.

• Question 97:

  Refer to the exhibit.

  

  When troubleshooting a network problem, a network analyzer is connected to Port f0/1 of a LAN switch. Which command can prevent BPDU transmission on this port?

  A. spanning-tree portfast bpduguard enable
  B. spanning-tree bpduguard default
  C. spanning-tree portfast bpdufilter default
  D. no spanning-tree link-type shared
  C. spanning-tree portfast bpdufilter default

• Question 98:

  A network engineer is setting up a new switched network. The network is expected to grow and add many new VLANs in the future. Which Spanning Tree Protocol should be used to reduce switch resources and managerial burdens that are associated with multiple spanning-tree instances?

  A. RSTP
  B. PVST
  C. MST
  D. PVST+
  E. RPVST+
  C. MST

• Question 99:

  On which interface can port security be configured?

  A. static trunk ports
  B. destination port for SPAN
  C. EtherChannel port group
  D. dynamic access point
  A. static trunk ports

• Question 100:

  Refer to the exhibit.

  

  Users of PC-1 experience slow connection when a webpage is requested from the server. To increase bandwidth, the network engineer configured an EtherChannel on interfaces Fa1/0 and Fa0/1 of the server farm switch, as shown here:

  Server_Switch#sh etherchannel load-balance

  EtherChannel Load-Balancing Operational State (src-mac):

  Non-IP: Source MAC address

  IPv4: Source MAC address

  IPv6: Source IP address

  Server_Switch#

  However, traffic is still slow. Which action can the engineer take to resolve this issue?

  A. Disable EtherChannel load balancing.
  B. Upgrade the switch IOS to IP services image.
  C. Change the load-balance method to dst-mac.
  D. Contact Cisco TAC to report a bug on the switch.
  C. Change the load-balance method to dst-mac.
