Google’s HTTPS infrastructure

Target entity: Google’s HTTPS infrastructure
Context triple: [Adam Langley, contributedTo, Google’s HTTPS infrastructure]

• A. Google’s global edge network
  Google’s global edge network is a worldwide infrastructure of distributed data centers and points of presence that delivers low-latency, high-performance connectivity and security services for Google and Google Cloud customers.
• B. Cleartext Considered Obsolete: Use of Transport Layer Security (TLS) for Email Submission and Access
  "Cleartext Considered Obsolete: Use of Transport Layer Security (TLS) for Email Submission and Access" (RFC 8314) is an IETF standards-track document that recommends and defines best practices for using TLS to secure email submission and retrieval protocols instead of unencrypted connections.
• C. Negotiated Finite Field Diffie-Hellman Ephemeral Parameters for Transport Layer Security (TLS)
  "Negotiated Finite Field Diffie-Hellman Ephemeral Parameters for Transport Layer Security (TLS)" is an IETF standard (RFC 7919) that defines secure, standardized finite-field Diffie-Hellman parameter sets for use in TLS to improve cryptographic security and interoperability.
• D. AT-TLS (Application Transparent TLS)
  AT-TLS (Application Transparent TLS) is an IBM z/OS networking function that transparently provides TLS encryption and decryption for application traffic without requiring changes to the applications themselves.
• E. DNS over DTLS
  DNS over DTLS is a protocol that secures DNS queries using Datagram Transport Layer Security over UDP, providing encryption and integrity while preserving DNS’s low-latency, connectionless nature.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
