Suggested Answer: C Vote an answer
When installing a HotFix on a BIG-IP device, F5 best practices require:
* Installing the base TMOS image on a new, unused boot volume (HD1.2)
* This ensures the upgrade happens on a clean volume.
* The existing active boot location remains untouched for rollback.
* Installing the HotFix onto the SAME new boot volume (HD1.2)
* HotFixes must be applied on top of a base version.
* They cannot be installed on an empty volume.
* They must match the base image version.
* Activating the new boot volume (HD1.2)
* The system reboots into the updated software stack.
* Activation happensafterbase + HotFix installation is complete.
This sequence is exactly shown inOption C:
Install base Image in HD1.2
Install HotFix in HD1.2
Activate HD1.2
Why the other options are incorrect:
A). Install HotFix before base image
* Impossible.
* HotFix requires an installed base version first.
B). Installing HotFix on HD1.1 (active boot volume)
* Not recommended.
* Upgrading in-place removes rollback safety.
* HotFix cannot be applied cleanly without applying base image first.
D). Activate HD1.2 before installing anything
* You cannot activate an empty boot volume.
* Activation only occurs after the base + HotFix software is installed.
