Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
/etc/containers/registries.conf using the unqualified-search-registries parameter
Why this is correct
The unqualified-search-registries setting allows Podman to prefix short image names with specified registry domains.
- ✗
/etc/sysconfig/podman using the SEARCH_REGISTRIES variable
Why it's wrong here
System environment configuration files do not control Podman short-name resolution logic.
- ✗
/etc/containers/registries.d/default.yaml using the search-domains parameter
Why it's wrong here
registries.d contains transport scopes and signature requirements, not short-name search expansion lists.
- ✗
~/.config/containers/auth.json using the default-registry key
Why it's wrong here
auth.json only stores authentication tokens and credentials.
