What is the effect of setting an ACR retention policy to 7 days?
- A All tags older than 7 days are deleted
- B Untagged manifests older than 7 days are deleted automatically (correct answer)
- C The registry is deleted after 7 days of inactivity
- D Soft-deleted items are purged after 7 days
Shortcut: The retention policy applies only to untagged manifests. Tagged images are unaffected; removing those requires az acr purge with explicit tag filters.
