CompTIA SK0-005 Practice Test 7
Question 60
A change board is planning a verified response to this server event: A file server with small random writes is being migrated from mirrored disks to a parity-only stripe solely to maximize reported usable capacity. For the RAID fault tolerance versus performance issue, which response elements belong in the approved plan? Select TWO answers.
- Both planned storage paths are available and storage latency remains within limits during controlled network failover.
- Choose a RAID level that meets measured capacity, write profile and disk-failure tolerance requirements, and retain independent backups.
- Assume that any RAID level, including striping without parity, guarantees single-disk survival.
- Select enterprise SSD endurance for the expected write volume and monitor NVMe health, utilization and replacement thresholds.
- Review workload I/O pattern, required fault tolerance, array health, usable capacity and rebuild time estimates.
Explanation
Correct Answer
B:RAID 0 offers no disk fault tolerance; parity and mirrors have different write and rebuild characteristics, and none replaces backup. Before rollout, confirm the problem with: Review workload I/O pattern, required fault tolerance, array health, usable capacity and rebuild time estimates.
E:These observations investigate the exact RAID fault tolerance versus performance failure rather than unrelated components. The expected technical relationship is: RAID 0 offers no disk fault tolerance; parity and mirrors have different write and rebuild characteristics, and none replaces backup.
Incorrect Answers
A:This statement concerns iSCSI network isolation and MPIO, a different Server+ technical control. It does not directly address the reported RAID fault tolerance versus performance fault or prove its repair.
C:This is the unsafe shortcut in the RAID fault tolerance versus performance scenario, not a justified remediation or diagnostic. RAID 0 offers no disk fault tolerance; parity and mirrors have different write and rebuild characteristics, and none replaces backup.
D:That option would select enterprise SSD endurance for the expected write volume and monitor NVMe health, utilization and replacement thresholds, but it addresses a different concern. RAID 0 offers no disk fault tolerance; parity and mirrors have different write and rebuild characteristics, and none replaces backup.
Question 61
A server administrator is investigating a server issue involving hot spare eligibility and rebuild supervision: A disk array enters a degraded state after one member fails, but its designated hot spare is smaller than the failed drive and never joins the rebuild. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.
- Provide compatible spare capacity and interface, replace the failed member, monitor the rebuild and verify array redundancy after completion.
- Choose a RAID level that meets measured capacity, write profile and disk-failure tolerance requirements, and retain independent backups.
- Declare an array healthy as soon as a replacement disk's activity light turns on.
- Rescan the device, extend the correct partition or volume manager layer and grow the supported filesystem using a backed-up change plan.
Explanation
Correct Answer
A:An array may remain vulnerable while degraded or rebuilding; a spare is useful only if the controller can use it.
Incorrect Answers
B:That option would choose a RAID level that meets measured capacity, write profile and disk-failure tolerance requirements, and retain independent backups, but it addresses a different concern.

D:This statement concerns Filesystem growth after LUN expansion, a different Server+ technical control. It does not directly address the reported Hot spare eligibility and rebuild supervision fault or prove its repair. For this incident, the relevant principle is: An array may remain vulnerable while degraded or rebuilding; a spare is useful only if the controller can use it. A targeted investigation checks: Examine controller event logs, physical drive size/type, spare assignment, rebuild progress and media-error counters. The desired recovery condition is: The rebuild completes without new errors and the controller reports all expected redundancy restored.
Question 62
While reviewing the CompTIA Server+ administration incident, a technician learns: A disk array enters a degraded state after one member fails, but its designated hot spare is smaller than the failed drive and never joins the rebuild. Which principle most directly explains how to address the described issue safely? Select ONE best answer.
- SAN high availability requires correctly presented LUNs over multiple independent usable fabric paths, not redundant cables alone.
- Flash storage performance and life depend on workload write intensity, remaining spare blocks and device health telemetry.
- Stable iSCSI performance and resilience depend on end-to-end network path design and host multipathing, not simply the number of NICs.
- An array may remain vulnerable while degraded or rebuilding; a spare is useful only if the controller can use it.
