CompTIA SK0-005 Practice Test 18
Question 170
A change board is planning a verified response to this server event: A database server stores application data, temporary files and backups together on a single undersized filesystem with no growth plan. For the Partition and mount strategy for server roles issue, which response elements belong in the approved plan? Select TWO answers.
- A fresh node installs the approved version reproducibly without credential disclosure or rogue boot sources.
- Inspect filesystem usage by mount, expected data/log growth, backup layout and application storage paths.
- Separate high-growth data and logs from critical system space using supported mount points, volume sizing and monitoring.
- Leave unlimited application logs on the OS boot volume because unused disk exists elsewhere.
- Implement desired-state checks and idempotent updates with logs and bounded retries so repeated runs converge.
Explanation
Correct Answer
B:These observations investigate the exact Partition and mount strategy for server roles failure rather than unrelated components. Incident: A database server stores application data, temporary files and backups together on a single undersized filesystem with no growth plan.
C:Before rollout, confirm the problem with: Inspect filesystem usage by mount, expected data/log growth, backup layout and application storage paths. This is the appropriate targeted correction for Partition and mount strategy for server roles.
Incorrect Answers
A:For this incident, the relevant principle is: File-system layout should reflect workload growth and recovery boundaries rather than only installer defaults. This statement concerns PXE and unattended installation integrity, a different Server+ technical control.
D:Instead, the supported correction is: Separate high-growth data and logs from critical system space using supported mount points, volume sizing and monitoring. Discriminate using: Inspect filesystem usage by mount, expected data/log growth, backup layout and application storage paths.
E:For this incident, the relevant principle is: File-system layout should reflect workload growth and recovery boundaries rather than only installer defaults. It does not directly address the reported Partition and mount strategy for server roles fault or prove its repair.
Question 171
A server administrator is investigating a server issue involving golden image lifecycle and os support: A team installs new servers from a two-year-old image containing unsupported packages and then skips patching because image deployment succeeded. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.
- Separate high-growth data and logs from critical system space using supported mount points, volume sizing and monitoring.
- Maintain supported, patched golden images with version pinning, vulnerability scanning and reproducible configuration validation.
- Restrict PXE and imaging infrastructure to trusted networks and protect signed, versioned images and unattended-install credentials.
- Treat an old image as secure indefinitely because it was once approved.
Explanation
Correct Answer
B:A successful OS install does not establish ongoing supportability or image provenance; images require lifecycle controls.
Incorrect Answers
A:This statement concerns Partition and mount strategy for server roles, a different Server+ technical control. It does not directly address the reported Golden image lifecycle and OS support fault or prove its repair. For this incident, the relevant principle is: A successful OS install does not establish ongoing supportability or image provenance; images require lifecycle controls. A targeted investigation checks: Compare OS vendor support dates, package inventory, image build ID and scan findings against the approved baseline. The desired recovery condition is: Newly deployed hosts match a supported baseline with documented provenance and no unapproved critical gaps.
C:This statement concerns PXE and unattended installation integrity, a different Server+ technical control. It does not directly address the reported Golden image lifecycle and OS support fault or prove its repair. For this incident, the relevant principle is: A successful OS install does not establish ongoing supportability or image provenance; images require lifecycle controls. A targeted investigation checks: Compare OS vendor support dates, package inventory, image build ID and scan findings against the approved baseline. The desired recovery condition is: Newly deployed hosts match a supported baseline with documented provenance and no unapproved critical gaps.
D:This is the unsafe shortcut in the Golden image lifecycle and OS support scenario, not a justified remediation or diagnostic. A successful OS install does not establish ongoing supportability or image provenance; images require lifecycle controls.
Question 172
While reviewing the CompTIA Server+ administration incident, a technician learns: A team installs new servers from a two-year-old image containing unsupported packages and then skips patching because image deployment succeeded. Which principle most directly explains how to address the described issue safely? Select ONE best answer.
- A running OS is not evidence that dependent services, resource budgets and health checks are correctly configured.
- UEFI, GPT and the installed bootloader must match a supported boot path; changing boot mode after installation can prevent startup.
- A successful OS install does not establish ongoing supportability or image provenance; images require lifecycle controls.
- Virtual network topology must be consistent across hosts, and hypervisor port groups enforce connectivity and isolation.

Question 175
A change board is planning a verified response to this server event: A team installs new servers from a two-year-old image containing unsupported packages and then skips patching because image deployment succeeded. For the Golden image lifecycle and OS support issue, which response elements belong in the approved plan? Select ONE best answer.
- Treat an old image as secure indefinitely because it was once approved.
- Align firmware boot mode, supported GPT partitioning and Secure Boot policy with the OS image before installation.

Question 177
While reviewing the CompTIA Server+ administration incident, a technician learns: An automation pipeline rebuilds production servers but never records the OS image version or package bill of materials for rollback. Which principle most directly explains how to address the described issue safely? Select ONE best answer.
- DNS answers depend on resolver selection, authoritative records and caching; a ping of one host does not validate all name-resolution paths.
- A successful OS install does not establish ongoing supportability or image provenance; images require lifecycle controls.
