Phrase: Trusted CA Indication extension | Statement: [RFC 6066, defines, Trusted CA Indication extension]

Target entity: Trusted CA Indication extension
Context triple: [RFC 6066, defines, Trusted CA Indication extension]

• A. Client Certificate URL extension
  The Client Certificate URL extension is a Transport Layer Security (TLS) mechanism that allows a client to provide a URL from which its certificate can be retrieved, rather than sending the certificate directly in the handshake.
• B. OCSP
  OCSP (Online Certificate Status Protocol) is an internet protocol used to obtain the real-time revocation status of digital certificates in public key infrastructures.
• C. 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.
• D. Certificate Enrollment Web Service
  Certificate Enrollment Web Service is a Windows server role service that enables certificate enrollment and renewal over HTTPS, typically used with Active Directory Certificate Services to support remote and policy-based certificate requests.
• E. DST Root CA X3
  DST Root CA X3 is a widely trusted root certificate authority operated by IdenTrust that historically provided the cross-signed trust anchor enabling broad browser compatibility for Let’s Encrypt certificates.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
