CompTIA SK0-005 Practice Test 25
Question 240
A change board is planning a verified response to this server event: A middleware daemon is repeatedly killed by memory pressure, and operators only reboot the host without inspecting service dependencies. For the Service dependency and restart management issue, which response elements belong in the approved plan? Select TWO answers.
- Target latency and throughput hold under representative peak load with monitored headroom.
- Configure every service to restart infinitely without investigating failed dependencies or resource exhaustion.
- Inspect service manager status, dependency graph, journal or event logs and memory/CPU pressure during startup.
- Correct service startup ordering and resource limits, monitor dependency health and validate controlled restarts.
- Right-size vCPU and RAM allocations using contention telemetry and supportable reservations or resource controls.
Explanation
Correct Answer
C:These observations investigate the exact Service dependency and restart management failure rather than unrelated components. The expected technical relationship is: A running OS is not evidence that dependent services, resource budgets and health checks are correctly configured.
D:A running OS is not evidence that dependent services, resource budgets and health checks are correctly configured. A successful outcome is: All required services start in order after reboot and pass application-level health checks.
Incorrect Answers
A:For this incident, the relevant principle is: A running OS is not evidence that dependent services, resource budgets and health checks are correctly configured. This statement concerns Server resource monitoring and capacity planning, a different Server+ technical control.
B:Incident: A middleware daemon is repeatedly killed by memory pressure, and operators only reboot the host without inspecting service dependencies.
E:For this incident, the relevant principle is: A running OS is not evidence that dependent services, resource budgets and health checks are correctly configured. The desired recovery condition is: All required services start in order after reboot and pass application-level health checks.
Question 241
A server administrator is investigating a server issue involving server resource monitoring and capacity planning: An API node saturates CPU every morning but the operations team has no baseline for usage spikes or headroom. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.
- Add more disk gigabytes whenever any performance metric worsens.
- Baseline CPU, memory, IOPS, network and latency against workload SLOs; adjust constrained capacity using measured evidence.
- Align share/export permissions with filesystem ACLs, least-privilege group membership and documented inheritance tests.
- Correct service startup ordering and resource limits, monitor dependency health and validate controlled restarts.
Explanation
Correct Answer
B:Capacity planning must identify the bottleneck resource and trend, not confuse free capacity with sufficient throughput. For this case, An API node saturates CPU every morning but the operations team has no baseline for usage spikes or headroom.
Incorrect Answers
A:This is the unsafe shortcut in the Server resource monitoring and capacity planning scenario, not a justified remediation or diagnostic. Capacity planning must identify the bottleneck resource and trend, not confuse free capacity with sufficient throughput.

A targeted investigation checks: Collect resource counters, queue depth, latency percentile, working-set and workload time series. The desired recovery condition is: Target latency and throughput hold under representative peak load with monitored headroom.
