Q54. 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.

Answer: C

B. primary VLAN

C. community VLAN

D. promiscuous VLAN

Answer: A


Q57. 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.

Answer: A

B. Configure a SPAN session to monitor the received traffic on interface g0/4 for all VLANs except VLAN 3.

C. Configure a SPAN session to monitor the received traffic on interface g0/5 only for VLAN 3.

D. Configure a SPAN session to monitor the received traffic on interface g0/5 for all VLANs except VLAN 3.

C. access

D. routing

Answer: A


Q61. A network engineer notices inconsistent Cisco Discovery Protocol neighbors according to the diagram that is provided. The engineer notices only a single neighbor that uses Cisco Discovery Protocol, but it has several routing neighbor relationships. What would cause the output to show only the single neighbor?

A. The routers are connected via a Layer 2 switch.

B. IP routing is disabled on neighboring devices.

C. Cisco Express Forwarding is enabled locally.

D. Cisco Discovery Protocol advertisements are inconsistent between the local and remote devices.

Answer: A


Q62. 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.

Answer: A


Q63. Which statement describes what happens if all VSL connections between the virtual switch

members are lost?
