Difficulty: HardTroubleshooting Methodology

Following an unexpected power outage, a system administrator replaces a damaged internal power supply on a high-availability network storage unit. The unit boots cleanly into the management dashboard. To adhere strictly to Step 5 (Verify full system functionality and, if applicable, implement preventive measures) of the CompTIA troubleshooting methodology, which of the following actions should the administrator perform? (Select TWO.)

  1. Execute a synthetic storage stress test and monitor volume I/O to ensure system stability under load.Answer
  2. Connect the storage unit to an online uninterruptible power supply (UPS) and verify power redundancy policies.Answer
  3. C
    Document the incident root cause, replacement component details, and resolution time in the ticketing system.
  4. D
    Re-assign IP address leases on the network switch using Layer 2 DHCP scope properties.

Answer

The administrator should execute a synthetic storage stress test to confirm load stability and connect the storage unit to an online UPS while verifying power redundancy policies.
Verifying full system functionality requires testing the system under realistic operational stress to ensure stability. Implementing preventive measures involves configuring hardware redundancy, such as an uninterruptible power supply (UPS), to safeguard against future power disruptions.

Step-by-Step Solution

1
Identify the current stage in the CompTIA 6-step troubleshooting methodology.
The scenario specifies that the repair (replacing the faulty power supply) is complete, placing the technician at Step 5: Verify full system functionality and implement preventive measures.
Correctly establishing the current stage dictates which actions are methodologically appropriate before proceeding to final documentation.
2
Evaluate potential actions for verifying full system functionality.
Running synthetic workloads under observation confirms that the storage unit remains operational and stable under load.
Verification requires active testing to ensure the original symptom does not recur under standard operating conditions.
3
Evaluate potential actions for implementing preventive measures.
Connecting the device to an uninterruptible power supply (UPS) prevents future electrical blackouts from damaging the system.
Preventive measures mitigate the risk of repeat incidents caused by similar environmental or hardware triggers.
