QUESTION 81

What is the effect of configuring the following command on a switch?

 

Switch(config) # spanning-tree portfast bpdufilter default

 

A.        If BPDUs are received by a port configured for PortFast, then PortFast is disabled and the

BPDUs are processed normally.

B.        If BPDUs are received by a port configured for PortFast, they are ignored and none are sent.

C.        If BPDUs are received by a port configured for PortFast, the port transitions to the

forwarding state.

D.        The command enables BPDU filtering on all ports regardless of whether they are configured

for BPDU filtering at the interface level.

 

Correct Answer: A

(Choose three.)

 

clip_image002

 

A.       The final active router is the router with IP address 172.16.11.111.

B.       The router with IP address 172.16.11.111 has preempt configured.

C.       The priority of the router with IP address 172.16.11.112 is preferred over the router with IP address 172.16.11.111.

D.       The IP address 172.16.11.115 is the virtual HSRP IP address.

E.        The router with IP address 172.16.11.112 has nonpreempt configured.

F.        The router with IP address 172.16.11.112 is using default HSRP priority.

clip_image006

 

A.       enables LACP unconditionally

B.       enables PAgP only if a PAgP device is detected

QUESTION 85

Refer to the exhibit. Which two statements are true? (Choose two.)

 

clip_image008

 

A.       Interface gigabitethernet 0/1 has been configured as Layer 3 ports.

B.       Interface gigabitethernet 0/1 does not appear in the show vlan output because switchport is

enabled.

C.       Interface gigabitethernet 0/1 does not appear in the show vlan output because it is

configured as a trunk interface.

D.       VLAN2 has been configured as the native VLAN for the 802.1q trunk on interface

gigabitethernet 0/1.

E.        Traffic on VLAN 1 that is sent out gigabitethernet 0/1 will have an 802.1q header applied.

F.        Traffic on VLAN 2 that is sent out gigabitethernet 0/1 will have an 802.1q header applied.

 

Correct Answer: CF

 

 

 

QUESTION 86

Which two statements about HSRP, VRRP, and GLBP are true? (Choose two.)

 

A.       GLBP allows for router load balancing of traffic from a network segment without the

different host IP configurations needed to achieve the same results with HSRP.

B.       GLBP allows for router load balancing of traffic from a network segment by utilizing the

creation of multiple standby groups.

C.       GLBP and VRRP allow for MD5 authentication, whereas HSRP does not.

D.       Unlike HSRP and VRRP, GLBP allows automatic selection and simultaneous use of multiple

available gateways.

E.        HSRP allows for multiple upstream active links being simultaneously used, whereas GLBP

does not.

 

Correct Answer: AD

 

 

QUESTION 87

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:

&nb
sp;

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?

clip_image010

 

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 Fa0/6 on switch SW_B will transition to a forwarding state and create a bridging loop.

 

Correct Answer: D

 

 

QUESTION 88

Refer to the exhibit. Which statement is true?

 

clip_image012

 

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.

 

Correct Answer: D

 

 

QUESTION 89

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.

 

Correct Answer: BD

 

 

QUESTION 90

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.
