Phrase: TLS ServerHello | Statement: [Max Fragment Length extension, usedIn, TLS ServerHello]

Target entity: TLS ServerHello
Context triple: [Max Fragment Length extension, usedIn, TLS ServerHello]

• A. ServerHello with extensions chosen
  ServerHello with extensions is a TLS handshake message variant that allows a server to include additional extension data to negotiate optional protocol features and capabilities with a client.
• B. TLS 1.2 Finished message
  The TLS 1.2 Finished message is the protocol’s final handshake message that proves both parties share the same session keys and that the preceding handshake messages have not been tampered with.
• C. TLS heartbeat extension (later deprecated)
  The TLS heartbeat extension was a Transport Layer Security protocol feature designed to keep secure connections alive and test reachability, later becoming widely known for the critical Heartbleed vulnerability that led to its deprecation.
• D. Server Name Indication extension
  The Server Name Indication (SNI) extension is a TLS protocol feature that allows a client to indicate the hostname it is trying to connect to at the start of the handshake so that the server can present the correct certificate for virtual hosting.
• E. ALPN (Application-Layer Protocol Negotiation)
  ALPN (Application-Layer Protocol Negotiation) is a TLS extension that allows clients and servers to agree on which application-layer protocol (such as HTTP/2 or SPDY) to use over a secure connection during the TLS handshake.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
