After applying an update—even if it “appears” successful—the next step is validation. In CompTIA Cloud+ (CV0-004) operational procedures, change management and maintenance activities require post-change verification to confirm the service is functioning as intended and that no regressions were introduced. For a code repository running on a VM, this includes confirming the repository service starts correctly, users can authenticate, read/write operations work, hooks/integrations function, and logs show no errors. This step also supports incident prevention and rapid rollback decision-making if issues are detected.

Option A (Back up the repository) is typically performed before making changes to protect against failed updates. Option C (Restore the repository) is only appropriate if testing reveals a failure or corruption and recovery is needed. Option B (Decommission the repository) is unrelated to a routine upgrade. Therefore, the most correct immediate action after the update is to test repository functionality to ensure availability, integrity, and expected operational behavior.
