Question 130

A change board is planning a verified response to this server event: An administrator updates RAID controller firmware across all storage nodes at once without checking the vendor-supported driver and firmware matrix. For the Firmware compatibility and staged maintenance issue, which response elements belong in the approved plan? Select TWO answers.

  1. Record installed firmware/driver versions, vendor advisories, compatibility notes and maintenance dependency order.
  2. Place BMC access on an isolated management network, change default credentials, restrict administrator access and maintain supported firmware.
  3. Validate the hardware compatibility matrix, test firmware and drivers in a pilot, arrange rollback and stagger production maintenance.
  4. Critical spare parts and tested replacement procedures are available, with sensor warnings resolved before failure.
  5. Install the newest firmware everywhere simultaneously without checking compatibility or rollback.

Explanation

Correct Answer

A:

These observations investigate the exact Firmware compatibility and staged maintenance failure rather than unrelated components. Use findings to decide whether to: Validate the hardware compatibility matrix, test firmware and drivers in a pilot, arrange rollback and stagger production maintenance.

C:

BIOS, BMC, controller firmware and drivers can have version dependencies; simultaneous fleet updates amplify risk. This is the appropriate targeted correction for Firmware compatibility and staged maintenance.

Incorrect Answers

B:

For this incident, the relevant principle is: BIOS, BMC, controller firmware and drivers can have version dependencies; simultaneous fleet updates amplify risk. It does not directly address the reported Firmware compatibility and staged maintenance fault or prove its repair.

D:

For this incident, the relevant principle is: BIOS, BMC, controller firmware and drivers can have version dependencies; simultaneous fleet updates amplify risk. This statement concerns Preventive hardware maintenance and spares, a different Server+ technical control.

E:

Incident: An administrator updates RAID controller firmware across all storage nodes at once without checking the vendor-supported driver and firmware matrix.

Question 131

A server administrator is investigating a server issue involving preventive hardware maintenance and spares: A remote branch stores no spare fans or drives and repeatedly waits days for replacements after predictable wear alerts. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.

  1. Wait for complete service outage before acting on persistent hardware health alarms.
  2. Validate the hardware compatibility matrix, test firmware and drivers in a pilot, arrange rollback and stagger production maintenance.
  3. Use lifecycle and alert data to schedule preventive maintenance, stock qualified critical spares and document replacement runbooks.
  4. Check component hot-swap support, follow power isolation requirements and use approved ESD handling procedures.

Explanation

Correct Answer

C:

Before rollout, confirm the problem with: Correlate sensor alarms, fault trends, part numbers, vendor lifecycle notices and support response agreements. Preventive maintenance reduces recoverable downtime by detecting degrading components and planning compatible replacements.

Incorrect Answers

A:

This is the unsafe shortcut in the Preventive hardware maintenance and spares scenario, not a justified remediation or diagnostic. Preventive maintenance reduces recoverable downtime by detecting degrading components and planning compatible replacements.

B:

That option would validate the hardware compatibility matrix, test firmware and drivers in a pilot, arrange rollback and stagger production maintenance, but it addresses a different concern. Preventive maintenance reduces recoverable downtime by detecting degrading components and planning compatible replacements.

D:

That option would check component hot-swap support, follow power isolation requirements and use approved ESD handling procedures, but it addresses a different concern. Preventive maintenance reduces recoverable downtime by detecting degrading components and planning compatible replacements.

Question 132

While reviewing the CompTIA Server+ administration incident, a technician learns: A remote branch stores no spare fans or drives and repeatedly waits days for replacements after predictable wear alerts. Which principle most directly explains how to address the described issue safely? Select ONE best answer.

  1. Two PSUs are not a redundant power design when both depend on one upstream power device or circuit.
  2. RAID 0 offers no disk fault tolerance; parity and mirrors have different write and rebuild characteristics, and none replaces backup.
  3. Rack placement must satisfy structural loading, chassis mounting specifications and designed airflow; a physically fitting rail is not proof of safe installation.
  4. Preventive maintenance reduces recoverable downtime by detecting degrading components and planning compatible replacements.

Explanation
