QUESTION 273

A network administrator is troubleshooting a problem of a CAPWAP access point that intermittently disconnects from the WLC. The administrator is trying to determine when the problem is happening. UDP port 514 is allowed. What is the best option for successfully gathering comprehensive information about the problem?

 

A.

Configure a script to log into the WLC to gather logs and save them on a PC, where they can be reviewed daily.

B.

The CAPWAP AP has no syslog capability but the WLC does have syslog capability. Configure the

WLC for syslog and level 1.

C.

Configure the CAPWAP AP and the WLC for syslog and level 6.

D.

Configure the CAPWAP AP for buffered logging and level 7. Configure the WLC for syslog and level 7.

E.

Configure the CAPWAP AP and the WLC for syslog and level 1.

 

Answer: C

 

 

QUESTION 274

Refer to the exhibit. You are testing the mesh AP feature in your lab. You begin by changing the AP mode from local to bridge on one of your Cisco 3500 Series APs. The AP reboots and attempts to rejoin the controller, but it fails to do so. Based upon the information in the exhibit, which two of these options would allow the AP to join the WLC? (Choose two.)

 

clip_image004

 

A.

Add 08:d0:9f:22:9e:10 to the AP Authorization List

B.

Add 08:d0:9f:22:9e:10 to the MAC Address Filter

C.

Add 64:9e:f3:0e:b6:76 to the AP Authorization List

D.

Add 64:9e:f3:0e:b6:76 to the MAC Address Filter

 

Answer: CD

 

 

QUESTION 275

Refer to the exhibit. A network administrator is configuring and installing an indoor mesh network using two CAPWAP APs. The APs were out of the box and have already been installed in their designated locations. The RAP is joined to the controller and configured appropriately, but the MAP is not visible on the WLC. In the output shown, which of these explanations is the most likely reason for the issue?

 

clip_image006

 

A.

The MAP should have been primed to the WLC before being deployed.

The Bridge Group Name is not configured by default.

The AP policy for the MAP is not configured.

B.

The MAP should have been primed to the WLC before being deployed.

The Bridge Group Name uses the MAC address and is configured but does not match, which is the

reason for the failure.

C.

The MAP does not have to be primed to the WLC before being deployed to the field because the

WLC discovery process is different for MAPs than it is for RAPs. The Bridge Group Name does not

have to match but the RAP has to have the MAP MAC address added to its database.

D.

The MAP should have been primed to the WLC before being deployed.

The Bridge Group Name does not need to match.

The MAP is running an LWAPP image that requires its MAC address to be configured in the RAP

in order for a successful join.

E.

The MAP does not have to be primed to the WLC before being deployed.

The Bridge Group Name needs to match. The AP policy is automatically populated by the MAP

discovery process via CAPWAP, but is failing in this example.

 

Answer: A

 

 

QUESTION 276

Your customer is attempting to create two WLANs with identical SSIDs and identical Layer 2 security policies on their WLC 5508, without success. Which two of these actions would help them? (Choose two.)

B.

Assign each WLAN to a different interface.

C.

Set the WLAN IDs to a number greater than 17.

CAPWAP

D.

Location

 

Answer: C

 

 

QUESTION 278

Upon troubleshooting, you determine that the users who are unable to receive the multicast video are all connected at 9 Mbps. Users that are connected at a data rate of 12 Mbps or higher are able to receive the multicast video. Which data rate can you modify to fix the problem?

 

clip_image008

 

A.

Change 6 Mbps to Supported.

B.

Change 6 Mbps to Mandatory.

C.

Change 9 Mbps to Supported.

B.

The client must use WPA2 with AES-CCMP.

C.

The client must use either EAP or PSK to obtain the PMK.

D.
