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?
- Allow port TCP/8443 on the firewall.
- Configure HTTP to HTTPS redirection.
- Configure the guest portal to listen on TCP/8443.
- Allow redirection from any client IP range.
Answer(s): B
Explanation:
HTTP to HTTPS redirection ensures that when a client attempts to access the guest portal using HTTP (port 80), they are automatically redirected to the secure HTTPS (port 443) version of the portal. This redirection helps enforce secure communication and prevents users from accessing the portal over an unencrypted connection.
