CWNP Exam CWNA-109 Topic 6 Question 12 Discussion

Actual exam question for CWNP's CWNA-109 exam

Question #: 12
Topic #: 6

You are troubleshooting a controller-based AP that is unable to locate the controller. DHCP is not use and the controller is located at 10.10.10.81/24 while the AP is on the 10.10.16.0/24 network. What should be inspected to verify proper configuration?

ANTP

BBOOTH

CDNS

DAP hosts file

Show Suggested Answer

Suggested Answer: C

What should be inspected to verify proper configuration isDNS. DNS stands for Domain Name System and is a service that resolves hostnames to IP addresses. In a controller-based AP deployment, DNS can be used to help the AP locate the controller by using a predefined hostname such as CISCO-CAPWAP-CONTROLLER or aruba-master. The AP sends a DNS query for this hostname and receives an IP address of the controller as a response. Therefore, if DNS is not configured properly or if there is no DNS entry for the controller hostname, the AP may not be able to locate the controller. NTP, BOOTP, and AP hosts file are not relevant for this scenario.Reference:[CWNP Certified Wireless Network Administrator Official Study Guide: Exam CWNA-109], page 374; [CWNA: Certified Wireless Network Administrator Official Study Guide: Exam CWNA-109], page 364.

Haha, what's BOOTH? Sounds like a typo or a joke answer! Anyway, I'm going with C) DNS too.

Let's make sure DNS is properly configured. That might be the problem.

I believe we should also inspect the AP hosts file.

I disagree, I think the answer is D) AP hosts file. If the DHCP is not in use, the AP needs to have the controller's IP address configured in its local hosts file.

Hmm, this one's tricky. I'd say the correct answer is C) DNS. The AP needs to be able to resolve the controller's hostname to its IP address, and that's what DNS is for.

But wouldn't checking the AP hosts file also be important? It could have the controller's IP address listed there.

I think you're right, C) DNS is the correct answer. The AP needs to know how to reach the controller.
