QUESTION 231

A network administrator is troubleshooting the OSPF configuration of routers R1 and R2. The routers cannot establish an adjacency relationship on their common Ethernet link. The graphic shows the output of the show ip ospf interface e0 command for routers R1 and R2. Based on the information in the graphic, what is the cause of this problem?

A.        The OSPF area is not configured properly.

B.        The priority on R1 should be set higher.

C.        The cost on R1 should be set higher.

D.        The hello and dead timers are not configured properly.

E.         A backup designated router needs to be added to the network.

F.         The OSPF process ID numbers must match.

 

Correct
Answer: D

A.        amount of RAM

B.        bridge priority

C.        IOS version

D.        IP address

QUESTION 233

Refer to the exhibit. This command is executed on 2960Switch:

 

2960Switch(config)# mac-address-table static 0000.00aa.aaaa vlan 10 interface fa0/1

 

Which two of these statements correctly identify results of executing the command?

(Choose two.)

 

clip_image002

 

A.       Port security is implemented on the fa0/1 interface.

B.       MAC address 0000.00aa.aaaa does not need to be learned by this switch.

C.       Only MAC address 0000.00aa.aaaa can source frames on the fa0/1 segment.

D.       Frames with a Layer 2 source address of 0000.00aa.aaaa will be forwarded out fa0/1.

< font color="#000000">E.        MAC address 0000.00aa.aaaa will be listed in the MAC address table for interface fa0/1 only.

 

Correct Answer: BE

 

 

QUESTION 234

Refer to the exhibit. Which statement is true?

 

clip_image003

 

A.       The Fa0/11 role confirms that Switch A is the root bridge for VLAN 20.

B.       VLAN 20 is running the Per VLAN Spanning Tree Protocol.

C.       The MAC address of the root bridge is 0017.596d.1580.

D.       Switch A is not the root bridge, because not all of the interface roles are designated.

 

Correct Answer: D

 

 

QUESTION 235

A.       RSTP cannot operate with PVST+.

B.       RSTP defines new port roles.

C.       RSTP defines no new port states.

D.       RSTP is a proprietary implementation of IEEE 802.1D STP.

E.        RSTP is compatible with the original IEEE 802.1D STP.

 

Correct Answer: BE

 

 

QUESTION 236

Refer to the exhibit. A junior network administrator was given the task of configuring port security on SwitchA to allow only PC_A to access the switched network through port fa0/1. If any other device is detected, the port is to drop frames from this device. The administrator configured the interface and tested it with successful pings from PC_A to RouterA, and then observes the output from these two show commands. Which two of these changes are necessary for SwitchA to meet the requirements? (Choose two.)

 

clip_image005


A.       Port security needs to be globally enabled.

B.       Port security needs to be enabled on the interface.

C.       Port security needs to be configured to shut down the interface in the event of a violation.

D.       Port security needs to be configured to allow only one learned MAC address.

E.        Port security interface counters need to be cleared before using the show command.

F.        The port security configuration needs to be saved to NVRAM before it can become active.

 

Correct Answer: BD

B.     switch(config-if)#switchport mode trunk

switch(config-if)#switchport port-security mac-address 1

 

C.     switch(config-if)#switchport mode access

switch(config-if)#switchport port-security maximum 1

 

D.     switch(config-if)#switchport mode access
