Question

what happens during a tls handshake?

a the server provides its digital certificate to the client for authentication.
b the server and client agree on a data compression method.
c the servers processing load is reduced.
d the client and server negotiate network congestion management.

Explanation:

Analyze the purpose of a TLS handshake

Using the SSL TLS Protocol knowledge point
The TLS handshake establishes a secure session by negotiating cipher suites, exchanging keys, and authenticating the identity of the communicating parties.

Evaluate the role of digital certificates

Using the Digital Certificates knowledge point
During the handshake, the server sends its digital certificate to the client so the client can verify the server's identity.

Assess the incorrect options

• Option B: Modern TLS versions (like TLS 1.3) disable compression due to security vulnerabilities (e.g., CRIME).
• Option C: Cryptographic handshakes increase processing load rather than reducing it.
• Option D: Congestion management is handled at the Transport Layer (TCP), not by TLS.

Answer:

• (A) The server provides its digital certificate to the client for authentication. (Correct answer)
• (B) The server and client agree on a data compression method.
• (C) The server's processing load is reduced.
• (D) The client and server negotiate network congestion management.
