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

SSL/TLS encryption and decryption are computationally expensive operations. By terminating SSL at the BIG-IP, web servers receive plain HTTP connections and are relieved of all cryptographic overhead, allowing them to dedicate their CPU cycles to serving application content and improving overall throughput and scalability.

Terminating SSL at the BIG-IP actually introduces unencrypted traffic on the internal network between the BIG-IP and the web servers unless a ServerSSL profile is used to re-encrypt that leg.

Same technical flaw as option B - SSL offload without re-encryption means traffic between the BIG-IP and pool members travels in cleartext internally.

An SSL certificate is still required and must be installed on the BIG-IP itself to present to connecting clients; offloading SSL does not eliminate the certificate requirement.

SSL acceleration hardware may still be needed or beneficial at the BIG-IP tier itself, especially under high connection volumes, so this advantage is not eliminated.
