Given that BIGIP-.iso and Hotfix-BIGIP--ENG.iso have been uploaded to /shared/images on an F5 device, what is the appropriate tmsh command to prepare and update the BIG-IP device with the hotfix of a software version on a new volume HD1.2?

Suggested Answer: B

When installing a BIG-IP software version with a HotFix on a new boot volume, F5 requires that both the base TMOS image and the HotFix image be installed together as part of the same installation workflow.

The correct process is:

Specify the base TMOS ISO

Specify the HotFix ISO that corresponds to that base version

Instruct the system to create a new boot volume

Install both images into that new volume

This is achieved with the following tmsh syntax:

tmsh install /sys software BIGIP-<version>.iso hotfix Hotfix-BIGIP-<version>-ENG.iso create-volume HD1.2

This command:

Installs the base image first

Applies the HotFix on top of the base image

Creates and installs everything on HD1.2

Leaves the currently active volume untouched for rollback

Why the other options are incorrect

A . Installing only the hotfix

A HotFix cannot be installed by itself on a new volume. A base image must already be present.

C . Using create instead of install

The create keyword is not valid for software installation operations.

D . Using copy

The copy command does not install software images or hotfixes.

I think it's A, but I'm not completely sure if the syntax is right for creating a new volume.
