CompTIA SK0-005 Practice Test 66
Question 650
A change board is planning a verified response to this server event: A hardware controller repeatedly drops one SATA drive from a hot-swap bay, and the team assumes the filesystem is the root cause. For the RAID degraded state and predictive drive failure issue, which response elements belong in the approved plan? Select TWO answers.
- Resolve physical media and negotiated speed/duplex compatibility, replacing defective optics or cabling as evidence dictates.
- Back up critical data, inspect controller/media events, replace failed components and rebuild with monitored redundancy.
- Read RAID member status, SMART/media diagnostics, backplane events, parity consistency and backup freshness.
- The affected application can write while block, inode and quota headroom meet policy.
- Force repeated rebuilds on failing drives without checking backup and additional media errors.
Explanation
Correct Answer
B:A successful outcome is: The array returns to a healthy redundant state with error-free checks and a verified recovery copy. Degraded or unstable storage may be one additional fault from data loss; immediate integrity and rebuild priorities matter.
C:Confirm remediation through: The array returns to a healthy redundant state with error-free checks and a verified recovery copy.
Incorrect Answers
A:This statement concerns NIC port errors and duplex mismatch, a different Server+ technical control.
D:A targeted investigation checks: Read RAID member status, SMART/media diagnostics, backplane events, parity consistency and backup freshness.
E:Incident: A hardware controller repeatedly drops one SATA drive from a hot-swap bay, and the team assumes the filesystem is the root cause.
Question 651
A server administrator is investigating a server issue involving filesystem full, inode exhaustion and quotas: A Linux server reports no free space despite many gigabytes available because millions of tiny files exhausted inodes. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.
- Expand the storage LUN whenever an application reports ENOSPC without checking inode or quota conditions.
- Inspect cache-protection health and replace or restore supported battery/flash protection before using safe cache policy.
- Validate zoning, masking, path policies and fabric independence; restore optimized healthy multipath.
- Identify whether blocks, inodes, quotas or reserved space is exhausted; reclaim or expand only the constrained resource.
Explanation
Correct Answer
D:Filesystem write failures can arise from inode or quota limits as well as free-block exhaustion. For this case, A Linux server reports no free space despite many gigabytes available because millions of tiny files exhausted inodes.
Incorrect Answers
A:This is the unsafe shortcut in the Filesystem full, inode exhaustion and quotas scenario, not a justified remediation or diagnostic. Filesystem write failures can arise from inode or quota limits as well as free-block exhaustion.
B:That option would inspect cache-protection health and replace or restore supported battery/flash protection before using safe cache policy, but it addresses a different concern. Filesystem write failures can arise from inode or quota limits as well as free-block exhaustion.
C:That option would validate zoning, masking, path policies and fabric independence; restore optimized healthy multipath, but it addresses a different concern. Filesystem write failures can arise from inode or quota limits as well as free-block exhaustion.
Question 652
While reviewing the CompTIA Server+ administration incident, a technician learns: A Linux server reports no free space despite many gigabytes available because millions of tiny files exhausted inodes. Which principle most directly explains how to address the described issue safely? Select ONE best answer.
- Filesystem write failures can arise from inode or quota limits as well as free-block exhaustion.
- Degraded or unstable storage may be one additional fault from data loss; immediate integrity and rebuild priorities matter.
- Evidence quality depends on provenance, timing and preservation, not only the volume of screenshots taken after recovery.
- Incident resolution includes timely escalation, safe rollback and documented follow-through, not just a green monitor.
Explanation
Correct Answer
A:Applying it leads to this operational action: Identify whether blocks, inodes, quotas or reserved space is exhausted; reclaim or expand only the constrained resource. The acceptance test is: The affected application can write while block, inode and quota headroom meet policy.
