Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 193

A Cisco ISE administrator is setting up Central Web Authentication to be used for user endpoint authentication. The client cannot reach the guest portal to log in and gain access, but DNS is functioning properly and the guest portal is enabled. What else must be configured to gain access?

Answer options

• A. Allow port TCP/8443 on the firewall.
• B. Configure HTTP to HTTPS redirection.
• C. Configure the guest portal to listen on TCP/8443.
• D. Allow redirection from any client IP range.

Correct answer: A

Explanation

The correct answer is A because allowing TCP/8443 on the firewall is essential for the client to reach the guest portal, which uses this port for secure communication. Options B and C are not correct as they do not address the firewall's role in connectivity, and option D is irrelevant since the issue is specific to port access rather than client IP address ranges.
