A BIG-IP Administrator needs to restore an encrypted UCS archive from the command line using the TMSH utility. Which TMSH command should the BIG-IP Administrator use to accomplish this?
Restoring system states from backups is a fundamental Control Plane administrative task2. When a User Configuration Set (UCS) archive is created with encryption, it requires the correct passphrase to be decrypted and loaded during the restoration process.
UCS Command Structure: The tmsh load /sys ucs command is the specific utility for restoring these comprehensive configuration archives.
Encrypted Restores: If the archive was encrypted during creation, the passphrase argument must be appended to the command followed by the actual password used to encrypt the file.
Comparison with Other Options:
load /sys config file is used for loading text-based configuration files (like bigip.conf), not full UCS archives6.
The no-license flag is used when you want to restore a configuration without overwriting the existing license (common during RMA replacements), but it does not provide the mechanism for entering an encryption passphrase.
