What is the next step after performing a UCS firmware upgrade, and downloading the latest drivers both for your RAID Controller and your Fibre Channel HBA? Check the HCL

Question

Options

• ANo Drivers are needed in a UCS environment
• BApply the device driver update to the devices
• CNo need to do anything Drivers are automatically installed for you
• DTest device driver compatibility

• A

• B
  3% (1)
• C
  8% (3)
• D
  84% (32)

Explanation

After downloading updated drivers and checking the Hardware Compatibility List (HCL), testing device driver compatibility (D) is the correct next step because verifying that the drivers work correctly in your specific UCS environment before deployment prevents production outages - the HCL confirms Cisco approves the driver, but testing confirms it actually functions properly in your setup.

Why the distractors are wrong:

• A is wrong because drivers absolutely are required in UCS environments - RAID controllers and FC HBAs depend on them to communicate with the OS.
• B is wrong because applying drivers before testing is skipping a critical validation step; applying comes after successful compatibility testing, not before.
• C is wrong because UCS does not automatically install updated drivers for you - driver management is a manual process the administrator owns.

Memory tip: Think of the sequence as D-T-A - Download, Test, Apply. The HCL check falls between downloading and testing: it's your "approved list" sanity check, but you still need to validate compatibility in your environment before touching production. Never skip the "T."
