What is the command line to verify the backup was created?

The correct answer from the provided CCSA item is D. The Gaia backup workflow uses Gaia Portal and Gaia Clish to create and review system backups. In the answer set, show backups is the only valid-looking Gaia Clish command intended to list backup information and confirm that backup output exists. The other options are malformed: show backup last-successful, show backup list-successful, and show backup successful are not proper Gaia-style commands for listing created backups. Check Point’s R82 Gaia documentation also describes verification/recovery workflows where administrators can open the gateway shell and use Gaia Clish backup-related show commands, including show backup logs, to locate the compressed backup file name after a backup operation. The course item’s expected command is therefore show backups, while the broader operational point is to verify backup creation from Gaia backup status/log information and ensure the generated .tgz backup file is present before relying on it.
