Why each option

This question asks if the purpose of Docker Content Trust (DCT) is to enable mutual TLS between the Docker client and server.

AYes

Mutual TLS is a security feature for authenticating both client and server during communication, which is distinct from the primary goal of Docker Content Trust, which is image content integrity and provenance.

BNoCorrect

Docker Content Trust (DCT) focuses on verifying the integrity and authenticity of Docker images through digital signatures, ensuring the image content has not been tampered with and comes from a trusted publisher; it does not directly enable or manage mutual TLS, which is a separate communication security mechanism.
