Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 193

The security policy mandates that only controller web management traffic is allowed from the IT subnet. In testing, an engineer is trying to connect to a WLAN with
Web Authentication for guest users, but the page is timing out on the wireless client browser. What is the cause of the issue?

Answer options

• A. The implemented CPU ACL on the controller is blocking HTTP/HTTPS traffic from the guest clients.
• B. Web Authentication Redirect is not supported with CPU ACLs.
• C. The DNS server that is configured on the controller is incorrect.
• D. Web Authentication Redirect is supported only with Internet Explorer, and the client is using Google Chrome.

Correct answer: A

Explanation

The correct answer is A because the implemented CPU ACL is restricting HTTP/HTTPS traffic, preventing guest clients from reaching the Web Authentication page. Option B is incorrect because the compatibility of Web Authentication Redirect with CPU ACLs does not affect the current issue. Options C and D are also not valid as they do not directly relate to the timeout problem experienced by the client.
