An SSL vServer is down after creation. Which of the following issues would most likely cause the vServer to stay DOWN?

• A. The SSL Certificate is NOT bound to the vServer.
• B. SSLv3 is disabled.
• C. The SSL services are NOT on the 10.102.29.X network.
• D. The vServer SSL port is NOT set to port 443.

Answer: (A)

A TLS handshake can only succeed if the SSL vServer has a certificate bound to it, with its private key available. Without a bound certificate, the vServer has nothing to present to clients during the handshake, so TLS cannot be established and the vServer stays down. Disabling SSLv3 doesn’t prevent TLS from working; the service can still negotiate a TLS session with modern clients, so the vServer wouldn’t typically be down just for that. If the backend SSL services aren’t on the expected network, that affects reachability to the real servers behind the vServer, but the front-end would still be able to come up and respond to TLS handshakes once a certificate is bound. Setting the vServer to listen on a port other than 443 would mean clients attempting HTTPS on 443 can’t reach it, but the vServer itself isn’t inherently down—it’s just listening on a different port.
