An administrator needs to complete the upgrade process from V7.3.1 to V7.3.2. What is the correct procedure?

Question

Options

• ACopy the ISO file extension to the recommended directories and use this file
• BUse the ISO file to execute the upgrade process
• CDo a clean installation using the ISO file on a bootable USB device
• DCopy the SFS file extension to the recommended directories and use this file

• B
  3% (1)
• C
  5% (2)
• D
  76% (28)

Explanation

Option D is correct because minor version upgrades (like V7.3.1 to V7.3.2) use SFS (System File System) files, not ISO files - you copy the SFS file to the recommended directories and apply it as an in-place upgrade, preserving existing configuration and data.

Option A is wrong for the same reason - using an ISO (not SFS) copied to directories is incorrect file format for this upgrade type. Option B is wrong because executing an ISO directly is not the proper upgrade mechanism for a minor patch release; the ISO isn't designed to run as an upgrade executable. Option C is wrong because a clean installation via bootable USB is a drastic, destructive process reserved for fresh deployments, not incremental version bumps - it would wipe existing configurations.

Memory tip: Think SFS = Small step upgrade (in-place, copy to directory), while ISO = full Install from Scratch Only. When the version change is minor (last digit), think SFS and directories, not ISO and USB drives.
