An administrator is upgrading a BIG-IP device and wants to ensure they can roll back if the upgrade fails. They have created a UCS archive. What else should they do to ensure a clean rollback?

Document the current configuration and custom files.

Record the current license key and re-enter it after the upgrade.

Note the current firmware version and download it for reinstallation.

Take a screenshot of the current configuration screens.

An administrator is about to upgrade a BIG-IP device and has created a UCS archive. What should they do with the archive to ensure it is available if the upgrade fails?

Print a copy of the configuration and keep it in a file.

Email it to the F5 support team.

Store it on an external server or removable media.

Store it on the same device's hard drive.

After completing a rolling upgrade of a BIG-IP pair, the administrator fails over traffic to the newly upgraded device. What is the first step to confirm the upgrade was successful?

Reboot the device to ensure the new version is stable.

Check the system logs for any warnings or errors.

Run a traffic test to ensure traffic flows correctly.

Verify that the configuration is intact and matches the pre-upgrade state.

A BIG-IP device is running version 12.1 and the target version is 15.1. The vendor documentation states that direct upgrades from 12.1 to 15.1 are not supported. What should the administrator do to ensure a successful upgrade?

Upgrade directly to 15.1 and rely on the configuration backup if it fails.

Upgrade to an intermediate version, such as 13.1, before upgrading to 15.1.

Skip the intermediate version and use a different target version that is supported.

Perform a factory reset and then install 15.1 directly.

A company runs a pair of BIG-IP devices in an active/standby configuration. They need to upgrade both devices to a new version with minimal traffic disruption. The standby device is currently in a failed state and cannot be brought online before the maintenance window. What should the administrator do to minimize downtime during the upgrade?

Upgrade both devices simultaneously during the maintenance window to save time.

Upgrade the standby device first, then fail over to it, and upgrade the original active device.

Perform the upgrade on the active device first, then fail over to it after the standby is upgraded.

Repair or replace the failed standby device before starting the upgrade, then perform a rolling upgrade.
