Question

A BIG-IP Administrator needs to install a HotFix on a standalone BIG-IP device, which has HD1.1 as the Active Boot Location. The BIG-IP Administrator has already re-activated the license and created an UCS archive of the configuration. In which sequence should the BIG-IP Administrator perform the remaining steps?

Options

  • AInstall HotFix in HD 1.1, Reboot the BIG-IP device. Install UCS Archive
  • BInstall HotFix in HO 1.2, Install base Image in HD 1.2, Activate HD1.2
  • CInstall base Image in HD1.2, Install HotFix in HD1.2, Activate HD 1.2
  • DActivate HD 1.2, Install base image in HD 1.2. Install HotFix in HD 1.2

Why each option

When applying a HotFix to a BIG-IP system with multiple boot locations, the best practice is to install the base image and then the HotFix onto an inactive boot location, followed by activating that new boot location. This process ensures a clean installation and provides a rollback option.

AInstall HotFix in HD 1.1, Reboot the BIG-IP device. Install UCS Archive

Installing a HotFix directly into the active boot location (HD1.1) is generally not recommended as it doesn't provide a clean rollback option and the base image isn't explicitly mentioned, which is crucial.

BInstall HotFix in HO 1.2, Install base Image in HD 1.2, Activate HD1.2

Installing the HotFix before the base image in the new boot location is incorrect because HotFixes are cumulative updates that require a specific base version to be present first.

CInstall base Image in HD1.2, Install HotFix in HD1.2, Activate HD 1.2Correct

The correct sequence for installing a HotFix on a BIG-IP involves first installing the appropriate base image (major version) onto an inactive boot location (HD1.2 in this case) to provide a fresh foundation. Next, the HotFix, which contains cumulative patches for that base version, is installed on top of the newly installed base image in the same boot location. Finally, this new boot location (HD1.2) is activated, allowing the system to boot into the updated software upon reboot.

DActivate HD 1.2, Install base image in HD 1.2. Install HotFix in HD 1.2

Activating HD1.2 before installing the base image and HotFix would result in booting to an empty or previous state, which is not the intended outcome for a new software installation.
