Refer to the exhibit. DHCP snooping is enabled for selected VLANs to provide security on the network. How do the switch ports handle the DHCP messages?
A. Ports Fa2/1 and Fa2/2 source DHCP requests only. Port Fa3/1 is eligible to source all DHCP messages and respond to DHCP requests.
B. Ports Fa2/1 and Fa2/2 respond to DHCP requests only. Port Fa3/1 is eligible to source all DHCP messages.
C. Ports Fa2/1 and Fa2/2 are eligible to source all DHCP messages and respond to DHCP requests. Port Fa3/1 can source DHCP request only.
D. All three ports, Fa2/1, Fa2/2, and Fa3/1, are eligible to source all DHCP messages and respond to DHCP requests.
Answer: C

Refer to the exhibit. Based on the output of the show command, what can you determine regarding EIGRP routing being performed by the switch?
A. There are 20 neighbors in the EIGRP neigbor table.
B. EIGRP is running normally and receiving IPv4 routing updates.
C. EIGRP status cannot be determined. The command show ip eigrp topology would determine the routing protocol status.
D. The switch has not established any neighbor relationships. Further network testing and troubleshooting must be performed to determine the cause of the problem.

QUESTION NO: 179
Why is BPDU guard an effective way to prevent an unauthorized rogue switch from altering the spanning-tree topology of a network?
A.BPDU guard can guarantee proper selection of the root bridge.
B.BPDU guard can be utilized along with PortFast to shut down ports when a switch is connected to the port.
C.BPDU guard can be utilized to prevent the switch from transmitting BPDUs and incorrectly altering the root bridge election.

Answer: B
QUESTION NO: 180
Refer to the exhibit and the partial configuration of switch SW_A and SW_B. STP is configured on all switches in the network. SW_B receives this error message on the console port:
00:06:34: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on FastEthernet0/5 (not half duplex), with SW_A FastEthernet0/4 (half duplex), with TBA05071417(Cat6K-B) 0/4 (half duplex).
What would be the possible outcome of the problem?
A. The root port on switch SW_A will automatically transition to full-duplex mode.
B. The root port on switch SW_B will fallback to full-duplex mode.
C. The interfaces between switches SW_A and SW_B will transition to a blocking state.
D. Interface Fa 0/6 on switch SW_B will transition to a forwarding state and create a bridging loop.
