5The answer is B, SSL_TCP, and this one tripped me up the first time because SSL_Bridge sounds like it would fit when you hear "TCP traffic." SSL_Bridge is the trap, it passes the encrypted traffic straight through to the back end without terminating the SSL session, so the server handles decryption, not the NetScaler. SSL_TCP is specifically designed for connection-based content switching where the appliance offloads SSL decryption before the traffic ever reaches your back-end servers, which is exactly what the question describes. If the traffic were HTTP-based you would reach for SSL_HTTP, but since this is raw TCP the SSL_TCP vserver is the right call every time.
Wesley nailed the SSL_Bridge trap, and the one thing worth adding is that SSL_TCP also lets the NetScaler do certificate-based client authentication before the connection even touches the back end, which is a bonus reason to reach for it on TCP offload scenarios.
SSL_TCP is your guy here, not SSL_Bridge which stays encrypted all the way, so B wins.
C, because you need HTTP-layer inspection after decryption, not raw TCP passthrough.
Hey Brenda, close call but it is actually B, because that scenario calls for inspection at the point before re-encryption hands off to the destination, which is exactly where B places the control, not at the HTTP application layer after the fact like C describes.
