Which is an advantage of terminating SSL communication at the BIGIP rather than the ultimate web server.

By terminating SSL at the BIG-IP, the BIG-IP handles the CPU-intensive encryption and decryption, sending unencrypted (or re-encrypted) traffic to the backend web servers, which significantly reduces the processing load on those servers.

Terminating SSL at the BIG-IP does not eliminate all unencrypted traffic from the internal network; traffic between the BIG-IP and web servers might still be unencrypted unless re-encrypted, and other internal network traffic is unaffected.

SSL certificates are still required for the BIG-IP to present to clients, so purchasing certificates from a certificate authority is not eliminated.

The BIG-IP itself often uses SSL acceleration hardware (either built-in or external) to efficiently handle SSL termination, so the need for acceleration hardware is not eliminated but rather centralized.
