CompTIA SK0-005 Practice Test 12
Question 110
A change board is planning a verified response to this server event: A storage server's SSD latency spikes and spare capacity falls below vendor guidance, but its SMART wear and media warnings are ignored. For the NVMe endurance and capacity monitoring issue, which response elements belong in the approved plan? Select TWO answers.
- Select enterprise SSD endurance for the expected write volume and monitor NVMe health, utilization and replacement thresholds.
- Review daily written bytes, manufacturer endurance ratings, NVMe critical warnings, percent-used and latency statistics.
- Use dedicated or appropriately isolated iSCSI paths with supported MPIO, correct initiator/target configuration and measured QoS.
- The host sees the intended LUN with active or standby paths on both fabrics and survives a single-fabric maintenance test.
- Treat SSDs as maintenance-free because they have no mechanical moving parts.
Explanation
Correct Answer
A:Flash storage performance and life depend on workload write intensity, remaining spare blocks and device health telemetry. This is the appropriate targeted correction for NVMe endurance and capacity monitoring.
B:These observations investigate the exact NVMe endurance and capacity monitoring failure rather than unrelated components. The expected technical relationship is: Flash storage performance and life depend on workload write intensity, remaining spare blocks and device health telemetry.
Incorrect Answers
C:That option would use dedicated or appropriately isolated iSCSI paths with supported MPIO, correct initiator/target configuration and measured QoS, but it addresses a different concern. Flash storage performance and life depend on workload write intensity, remaining spare blocks and device health telemetry. This statement concerns iSCSI network isolation and MPIO, a different Server+ technical control.
D:This statement concerns Fibre Channel SAN zoning and multipath, a different Server+ technical control. It does not directly address the reported NVMe endurance and capacity monitoring fault or prove its repair.
E:Incident: A storage server's SSD latency spikes and spare capacity falls below vendor guidance, but its SMART wear and media warnings are ignored.
Question 111
A server administrator is investigating a server issue involving esd and hot-swap replacement procedure: A technician opens a live chassis and pulls a non-hot-swappable adapter without verifying maintenance instructions or grounding. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.
- Assume every modular server part is hot-swappable and ESD precautions are optional.
- Validate the hardware compatibility matrix, test firmware and drivers in a pilot, arrange rollback and stagger production maintenance.
- Use lifecycle and alert data to schedule preventive maintenance, stock qualified critical spares and document replacement runbooks.
- Check component hot-swap support, follow power isolation requirements and use approved ESD handling procedures.
