Answer: C

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

A. switch1
channel-group 1 mode active switch2
channel-group 1 mode auto
B. switch1
channel-group 1 mode desirable switch2
channel-group 1 mode passive
C. switch1
channel-group 1 mode on switch2
channel-group 1 mode auto
D. switch1
channel-group 1 mode desirable switch2
channel-group 1 mode auto
Answer: D
Q9. What is the maximum number of 10 Gigabit Ethernet connections that can be utilized in an EtherChannel for the virtual switch link?
A. 4
B. 6
C. 8
D. 12
Answer: C
Q10. Which statement describes what happens if all VSL connections between the virtual switch
members are lost?
A. Both virtual switch members cease to forward traffic.
B. The VSS transitions to the dual active recovery mode, and both virtual switch members continue to forward traffic independently.
C. The virtual switch members reload.
D. The VSS transitions to the dual active recovery mode, and only the new active virtual switch continues to forward traffic.
Answer: D
Q11. Which VLAN range is eligible to be pruned when a network engineer enables VTP pruning on a switch?
A. VLANs 1-1001
B. VLANs 1-4094
C. VLANs 2-1001
D. VLANs 2-4094
Answer: C
Q12. A new network that consists of several switches has been connected together via trunking interfaces. If all switches currently have the default VTP domain name "null", which statement describes what happens when a domain name is configured on one of the switches?
A. The switch with the non-default domain name restores back to "null" upon reboot.
B. Switches with higher revision numbers does not accept the new domain name.
C. VTP summary advertisements are sent out of all ports with the new domain name.
D. All other switches with the default domain name become VTP clients.
Answer: C
Q13. What happens on a Cisco switch that runs Cisco IOS when an RSTP-configured switch receives 802.1d BPDU?
A. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives an 802.1d BPDU, it responds with an 802.1d BPDU and eventually the two switches run 802.1d to communicate.
B. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it responds with a 802.1d BPDU and eventually the two switches run 802.1d to communicate.
C. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU.
D. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU and eventually the two switches run 802.1d to communicate.
Answer: A
Q14. 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.
Answer: A
Q15. 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
