Actual exam question for ISC's CC exam
Question #: 396
Topic #: 1
Which TLS extension is used to optimize the TLS handshake process by reducing the number of round trips between the client and server?

Suggested Answer: C Vote an answer

TLS Session Resumption is used to optimize the TLS handshake process by reducing the number of round trips required between the client and server. Instead of performing a full handshake, session resumption allows previously negotiated security parameters to be reused.
This significantly improves performance and reduces latency, especially for applications with frequent connections such as web services and APIs. Session resumption can be implemented using session IDs or session tickets.
TLS renegotiation re-establishes parameters mid-session, TLS heartbeat is unrelated and historically associated with vulnerabilities, and "TLS FastTrack" is not a valid standard. TLS Session Resumption is formally defined in TLS specifications and is widely used in modern secure communications.
