What is the Podman command to log in to registry.access.redhat.com?

• A. sudo podman login -u username -p password registry.access.redhat.com
• B. sudo podman login registry.access.redhat.com -u username -p password
• C. sudo podman registry login -u username -p password
• D. sudo podman login --registry registry.access.redhat.com -u username -p password

Answer: (A)

Podman login authenticates to a registry by providing credentials with -u and -p and placing the registry address as the final argument. The command shown uses sudo to run with the needed privileges, supplies the username and password, and then specifies the registry host at the end, matching the standard syntax: podman login -u USERNAME -p PASSWORD REGISTRY. This is the correct form because the registry target is the positional argument and the credential options come before it. The other structures either misplace the registry, imply a non-existent subcommand, or use an unrecognized option, so they wouldn’t be valid.
