QUESTION 26
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 is 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 fall back 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.

Answer: D

QUESTION 27

A.    IP traffic matching access list ABC is forwarded through VLANs 5-10.
B.    IP traffic matching VLAN list 5-10 is forwarded, and all other traffic is dropped.
C.    All VLAN traffic matching VLAN list 5-10 is forwarded, and all traffic matching access list ABC is dropped.
D.    All VLAN traffic in VLANs 5-10 that match access list ABC is forwarded, and all other traffic is dropped.

Answer: D

QUESTION 28
Which two statements about HSRP are true? (Choose two.)

A.    Load sharing with HSRP is achieved by creating multiple subinterfaces on the HSRP routers.
B.    Load sharing with HSRP is achieved by creating HSRP groups on the HSRP routers.
C.    Routers configured for HSRP must belong only to one group per HSRP interface.
D.    Routers configured for HSRP can belong to multiple groups and multiple VLANs.
E.    All routers configured for HSRP load balancing must be configured with the same priority.

Answer: BD

QUESTION 29
Which statement about 802.1x port-based authentication is true?

A.    Hosts are required to have an 802.1x authentication client or utilize PPPoE.
B.    Before transmitting data, an 802.1x host must determine the authorization state of the switch.
C.    RADIUS is the only supported authentication server type.
D.    If a host initiates the authentication process and does not receive a response, it assumes it is not authorized.

Answer: C

QUESTION 30
Refer to the exhibit. Switch S1 has been configured with the command spanning-tree mode rapid-pvst. Switch S3 has been configured with the command spanning-tree mode mst. Switch S2 is running the IEEE 802.1D instance of Spanning Tree. What is the result?

A.    IEEE 802.1w and IEEE 802.1s are compatible. IEEE 802.1d is incompatible. Switches S1 and S3 can pass traffic between themselves. Neither can pass traffic to switch S2.
B.    Switches S1, S2, and S3 can pass traffic between themselves.
C.    Switches S1, S2, and S3 can pass traffic between themselves. However, if the topology is changed, switch S2 does not receive notification of the change.
D.    IEEE 802.1d, IEEE 802.1w, and IEEE 802.1s are incompatible. All three switches must use the same standard or no traffic can pass between any of the switches.
