Q61. A network engineer changed the port speed and duplex setting of an existing EtherChannel bundle that uses the PAgP protocol. Which statement describes what happens to all ports in the bundle?

A. PAgP changes the port speed and duplex for all ports in the bundle.

B. PAgP drops the ports that do not match the configuration.

C. PAgP does not change the port speed and duplex for all ports in the bundle until the switch is rebooted.

D. PAgP changes the port speed but not the duplex for all ports in the bundle.

Answer: A


Q62. Which First Hop Redundancy Protocol is an IEEE Standard?

A. GLBP

B. HSRP

C. VRRP

D. OSPF

Answer: C


Q63. Several new switches have been added to the existing network as VTP clients. All of the new switches have been configured with the same VTP domain, password, and version. However, VLANs are not passing from the VTP server (existing network) to the VTP clients. What must be done to fix this?

A. Remove the VTP domain name from all switches with "null" and then replace it with the new domain name.

B. Configure a different native VLAN on all new switches that are configured as VTP clients.

C. Provision one of the new switches to be the VTP server and duplicate information from the existing network.

D. Ensure that all switch interconnects are configured as trunks to allow VTP information to be transferred.

Answer: D


Q64. after configuring new data VLANs 1020 through 1030 on the VTP server, a network engineer notices that none of the VTP clients are receiving the updates. What is the problem?

A. The VTP server must be reloaded.

B. The VTP version number must be set to version 3.

C. After each update to the VTP server, it takes up to 4 hours propagate.

D. VTP must be stopped and restarted on the server.

E. Another switch in the domain has a higher revision number than the server.

Answer: B


Q65. which statement about the use of PAgP link aggregation on a Cisco switch that is running Cisco IOS Software is true?

A. PAgP modes are off, auto, desirable, and on. Only the combinations auto-desirable, desirable-desirable, and on-on allow the formation of a channel.

B. PAgP modes are active, desirable, and on. Only the combinations active-desirable, desirable-desirable, and on-on allow the formation of a channel.

C. PAgP modes are active, desirable, and on. Only the combinations active-active, desirable-desirable, and on-on allow the formation of a channel.

D. PAgP modes are off, active, desirable, and on. Only the combinations auto-auto, desirable-desirable, and on-on allow the formation of a channel.

Answer: A


Q66. Which statement about using EtherChannel on Cisco IOS switches is true?

A. A switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 8 Gbps only for Gigabit EtherChannel.

B. A switch can support up to 10 compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 1000 Mbps only for Fast EtherChannel or 8 Gbps only for Gigabit EtherChannel.

C. A switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 16 Gbps only for Gigabit EtherChannel.

D. A switch can support up to 10 compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 1000 Mbps only for Fast EtherChannel or 10 Gbps only for Gigabit EtherChannel.

Answer: A


Q67. Which private VLAN can have only one VLAN and be a secondary VLAN that carries unidirectional traffic upstream from the hosts toward the promiscuous ports and the gateway?

A. isolated VLAN

B. primary VLAN

C. community VLAN

D. promiscuous VLAN

Answer: A


Q68. Which statement describes what happens when a switch enters dual active recovery mode?

A. The switch shuts down and waits for the VSL link to be restored before sending traffic.

B. All interfaces are shut down in the formerly active virtual switch member, but the new active virtual switch forwards traffic on all links.

C. The switch continues to forward traffic out all links and enables spanning tree on VSL link and all other links to prevent loops.

D. The VSS detects which system was last in active state and shuts down the other switch.

Answer: B


Q69. Which option is a benefit of using VSS?

A. reduces cost

B. simplifies configuration

C. provides two independent supervisors with two different control planes

D. removes the need for a First Hop Redundancy Protocol

Answer: D


Q70. A Cisco Catalyst switch that is prone to reboots continues to rebuild the DHCP snooping database. What is the solution to avoid the snooping database from being rebuilt after every device reboot?

A. A DHCP snooping database agent should be configured.

B. Enable DHCP snooping for all VLANs that are associated with the switch.

C. Disable Option 82 for DHCP data insertion.

D. Use IP Source Guard to protect the DHCP binding table entries from being lost upon rebooting.

E. Apply ip dhcp snooping trust on all interfaces with dynamic addresses.

Answer: A
