CompTIA SK0-005 Practice Test 16
Question 150
A change board is planning a verified response to this server event: A replacement boot disk exceeds the legacy MBR addressing design and the new operating system image cannot use the planned partition layout. For the UEFI boot and GPT provisioning issue, which response elements belong in the approved plan? Select TWO answers.
- Inspect boot mode, partition-table format, Secure Boot state, boot entries and installation media support.
- Toggle between legacy BIOS and UEFI at random after installation to make an incompatible bootloader work.
- Correct service startup ordering and resource limits, monitor dependency health and validate controlled restarts.
- Newly deployed hosts match a supported baseline with documented provenance and no unapproved critical gaps.
- Align firmware boot mode, supported GPT partitioning and Secure Boot policy with the OS image before installation.
Explanation
Correct Answer
A:These observations investigate the exact UEFI boot and GPT provisioning failure rather than unrelated components. The expected technical relationship is: UEFI, GPT and the installed bootloader must match a supported boot path; changing boot mode after installation can prevent startup.
E:UEFI, GPT and the installed bootloader must match a supported boot path; changing boot mode after installation can prevent startup. This is the appropriate targeted correction for UEFI boot and GPT provisioning.
Incorrect Answers
B:Incident: A replacement boot disk exceeds the legacy MBR addressing design and the new operating system image cannot use the planned partition layout.
C:For this incident, the relevant principle is: UEFI, GPT and the installed bootloader must match a supported boot path; changing boot mode after installation can prevent startup. It does not directly address the reported UEFI boot and GPT provisioning fault or prove its repair.
D:For this incident, the relevant principle is: UEFI, GPT and the installed bootloader must match a supported boot path; changing boot mode after installation can prevent startup. This statement concerns Golden image lifecycle and OS support, a different Server+ technical control.
Question 151
A server administrator is investigating a server issue involving pxe and unattended installation integrity: A provisioning VLAN receives PXE replies from an unauthorized imaging server and installs the wrong operating-system build on new nodes. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.
- Align firmware boot mode, supported GPT partitioning and Secure Boot policy with the OS image before installation.
- Use any responding PXE image server and store administrative passwords in public install scripts.
- 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.
Explanation
Correct Answer
D:A successful outcome is: A fresh node installs the approved version reproducibly without credential disclosure or rogue boot sources. For this case, A provisioning VLAN receives PXE replies from an unauthorized imaging server and installs the wrong operating-system build on new nodes.
Incorrect Answers
A:For this incident, the relevant principle is: Network boot is a high-trust supply chain; authenticated image provenance and secret protection matter as much as automation speed. A targeted investigation checks: Trace DHCP/PXE boot source, image hashes and signatures, access ACLs and answer-file permissions.
B:This is the unsafe shortcut in the PXE and unattended installation integrity scenario, not a justified remediation or diagnostic. Network boot is a high-trust supply chain; authenticated image provenance and secret protection matter as much as automation speed.
C:For this incident, the relevant principle is: Network boot is a high-trust supply chain; authenticated image provenance and secret protection matter as much as automation speed. This statement concerns Golden image lifecycle and OS support, a different Server+ technical control.
Question 152
While reviewing the CompTIA Server+ administration incident, a technician learns: A provisioning VLAN receives PXE replies from an unauthorized imaging server and installs the wrong operating-system build on new nodes. 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.
- Live migration depends on compatible host features and enough resources on the target, even if the guest OS is unchanged.
- File-system layout should reflect workload growth and recovery boundaries rather than only installer defaults.
- Network boot is a high-trust supply chain; authenticated image provenance and secret protection matter as much as automation speed.
