Phrase: ServerHello with extensions | Statement: [RFC 3546, definesMessageBehavior, ServerHello with extensions]

Target entity: ServerHello with extensions
Context triple: [RFC 3546, definesMessageBehavior, ServerHello with extensions]

• A. 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.
• 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 1.1
  TLS 1.1 is an older version of the Transport Layer Security protocol that improved upon earlier SSL standards but has since been deprecated in favor of more secure versions like TLS 1.2 and 1.3.
• D. QUIC TLS usage specification
  The QUIC TLS usage specification is an IETF document that defines how the QUIC transport protocol integrates and uses TLS for secure, encrypted internet communication.
• E. RFC 8446
  RFC 8446 is the Internet standard that specifies TLS 1.3, a major revision of the Transport Layer Security protocol focused on improved security and performance for encrypted communications.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
