Docker Content Trust (DCT) is not used to indicate official images on Docker Hub.
Official Images on Docker Hub:
* Are managed and maintained by Docker, Inc.
* Are identified by their namespace location (no username prefix)
* Have a "Official Image" badge on Docker Hub
* Go through Docker's verification process
* Example: nginx, ubuntu, mysql (vs. username/nginx)
B is correct.
No, Docker Content Trust (DCT) does not inherently indicate whether an image on Docker Hub is an official image. Docker Content Trust is focused on ensuring the authenticity and integrity of an image through cryptographic signatures. It guarantees that the image being pulled or pushed has been signed by a trusted party, providing confidence that the image has not been tampered with.
