Q2. After UDLD is implemented, a Network Administrator noticed that one port stops receiving UDLD packets. This port continues to reestablish until after eight failed retries. The port then transitions into the errdisable state. Which option describes what causes the port to go into the errdisable state?

D. UDLD timers are inconsistent.

Answer: B

Q3. A network engineer is trying to deploy a PC on a network. The engineer observes that when the PC is connected to the network, it takes 30 to 60 seconds for the PC to see any activity on the network interface card. Which Layer 2 enhancement can be used to eliminate this delay?

A. Configure port duplex and speed to auto negotiation.

B. Configure port to duplex full and speed 1000.

C. Configure spanning-tree portfast.

D. Configure no switchport.

Answer: C

Q4. Which option is a benefit of using VSS?

A. reduces cost

B. simplifies configuration

Q6. 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

Q7. 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

Answer: B

Q10. 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
