Q4. A network engineer configured an Ethernet switch using these commands. Switchone(config) # Spanning-tree portfast bpdufilter default

Which statement about the spanning-tree portfast feature on the switch is true?

A. If an interface is enabled for portfast receives BDPU, the port goes through the spanning-tree listening, learning, and forwarding states.

B. If an interface is enabled for portfast receives BDPU, the port does not go through the spanning-tree listening, learning, and forwarding states.

C. If an interface is enabled for portfast receives BDPU, the port is shut down immediately.

D. If an interface is enabled for portfast receives BDPU, the port goes into the spanning- tree inconsistent state.

Answer: A

Q5. 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

Q6. Refer to the exhibit.

How can the traffic that is mirrored out the GigabitEthernet0/48 port be limited to only traffic that is received or transmitted in VLAN 10 on the GigabitEthernet0/1 port?

A. Change the configuration for GigabitEthernet0/48 so that it is a member of VLAN 10.

B. Add an access list to GigabitEthernet0/48 to filter out traffic that is not in VLAN 10.

C. Apply the monitor session filter globally to allow only traffic from VLAN 10.

D. Change the monitor session source to VLAN 10 instead of the physical interface.

Answer: C

Q7. 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

Q8. What does the command vlan dot1q tag native accomplish when configured under global

configuration?

A. All frames within the native VLAN are tagged, except when the native VLAN is set to 1.

B. It allows control traffic to pass using the non-default VLAN.

C. It removes the 4-byte dot1q tag from every frame that traverses the trunk interface(s).

D. Control traffic is tagged.

Answer: D

Q9. Interface FastEthernet0/1 is configured as a trunk interface that allows all VLANs. This command is configured globally:

monitor session 2 filter vlan 1 - 8, 39, 52

What is the result of the implemented command?

A. All VLAN traffic is sent to the SPAN destination interface.

B. Traffic from VLAN 4 is not sent to the SPAN destination interface.

C. Filtering a trunked SPAN port effectively disables SPAN operations for all VLANs.

D. The trunk's native VLAN must be changed to something other than VLAN 1.

E. Traffic from VLANs 1 to 8, 39, and 52 is replicated to the SPAN destination port.

Answer: E
