The five questions
1. Refer to the exhibit. A technician checks the Print Spooler on a Windows server with PowerShell and must bring it back without rebooting. Which command restarts this stopped service?
- A. Restart-Service -Name Spooler
- B. Start-Process -FilePath Spooler
- C. Restart-Computer -Force Spooler
- D. Set-Service -Name Spooler -StartupType Automatic
Correct answer: A.
Restart-Service stops and starts a Windows service, and on an already-stopped service it simply starts it; naming Spooler brings the Print Spooler back to Running without a reboot, which is what the scenario needs.
Why the others are wrong. Start-Process launches an executable file, not a registered service, so it cannot control Spooler. Restart-Computer reboots the whole server, which is far more disruptive than needed. Set-Service with -StartupType Automatic only changes how the service starts at boot; it does not start the stopped service now.
2. When loading equipment into a server rack, which two practices improve stability and cooling in the enclosure? (Choose two.)
- A. Leave power cables coiled inside intakes
- B. Mount the heaviest devices near the bottom
- C. Fill all gaps with cardboard filler
- D. Install blanking panels over empty slots
- E. Stack servers directly without rails
Correct answer: B.
Mounting the heaviest devices near the bottom lowers the rack's center of gravity for stability, and installing blanking panels over empty slots blocks hot-air recirculation, so both directly improve stability and cooling.
Why the others are wrong. Leaving power cables coiled inside intakes obstructs airflow rather than helping it. Filling gaps with cardboard is a fire hazard and not an approved airflow blocker. Stacking servers without rails is unsafe and unsupported, so none of these three improve the enclosure.
3. A technician is planning rack space for a new server the vendor lists as occupying 2U. How much vertical rack height will the server consume?
- A. 3.5 inches
- B. 1.75 inches
- C. 5.25 inches
- D. 7 inches
Correct answer: A.
A rack unit, or U, equals 1.75 inches of vertical height, so a 2U server occupies two of those units, which is exactly 3.5 inches of space in the rack.
Why the others are wrong. 1.75 inches is only a single rack unit, or 1U, not two. 5.25 inches represents 3U of height, and 7 inches represents 4U, so both of those figures overstate the space a 2U chassis actually consumes in the rack.
4. A security team wants a domain controller with the smallest attack surface and fewest monthly patches, managed remotely with no local GUI. Which Windows Server installation option best fits?
- A. Desktop Experience
- B. Server Core
- C. Windows Admin Center only
- D. Nano Server container image
Correct answer: B.
Server Core installs without the full desktop shell, so it has fewer components, a smaller attack surface, and fewer patches each month; it is administered remotely with PowerShell, RSAT, or Windows Admin Center, which matches every stated requirement.
Why the others are wrong. Desktop Experience adds the full GUI and more components, increasing patch load and attack surface. Windows Admin Center is a management tool, not an installation option you select at setup. Nano Server is now only a container base image and cannot run the domain controller role, so it does not fit a DC.
5. A technician grants a new help-desk employee only the permissions needed to reset user passwords and nothing more. Which security principle does this practice follow?
- A. Separation of duties
- B. Least privilege
- C. Defense in depth
- D. Implicit deny
Correct answer: B.
Least privilege means giving a user only the access required to perform their job and nothing extra, which is exactly reset-password rights and no more, limiting the damage if the account is misused or compromised.
Why the others are wrong. Separation of duties splits a sensitive task across people so no single person controls it, which granting one narrow right does not do. Defense in depth layers multiple controls rather than scoping one account. Implicit deny blocks anything not expressly allowed but does not describe assigning minimal rights.
6. A user reports that an application server 'feels slow' this morning. Following the CompTIA troubleshooting methodology, what should the technician do first?
- A. Establish a plan of action to resolve the issue
- B. Reboot the server to clear the slow condition
- C. Document the findings and the final resolution
- D. Identify the problem by gathering information and questioning the user
Correct answer: D.
The first methodology step is to identify the problem: gather information, question the user, and identify symptoms before forming any theory. Acting before understanding the issue risks wasting effort or masking the real cause of the slowness.
Why the others are wrong. Establishing a plan of action is step four and cannot precede identifying the problem. Rebooting is an untested change made before any theory exists and may destroy evidence of the cause. Documenting findings is the final step, done only after the issue is resolved and functionality verified with the user.
7. A small office with no data-center rack needs a single file server that sits on the floor beside a desk. Which server form factor fits best?
- A. Blade server
- B. 1U rack server
- C. 2U rack server
- D. Tower server
Correct answer: D.
A tower server is a self-contained standalone unit that sits on the floor or a desk and needs no rack, making it the right fit for a small office without any rack infrastructure.
Why the others are wrong. Blade servers require a chassis and a rack, adding cost and complexity a small office does not need. Both the 1U and 2U rack servers assume a mounting rack is present, which this office does not have available for installation.
8. An administrator must add the DNS Server role to a Server Core system that has no graphical Server Manager. Which command installs the role?
- A. Add-Role DNS
- B. Install-WindowsFeature DNS -IncludeManagementTools
- C. Set-Service DNS -StartupType Automatic
- D. Enable-WindowsOptionalFeature -FeatureName DNS
Correct answer: B.
Install-WindowsFeature is the PowerShell cmdlet that installs a server role such as DNS on Server Core, and -IncludeManagementTools adds the matching admin tools; it runs with no GUI, meeting the headless requirement.
Why the others are wrong. Add-Role is not a real cmdlet. Set-Service only changes an existing service's startup type; it cannot install a role that is not present. Enable-WindowsOptionalFeature manages optional client features, not server roles, and DNS is not a valid feature name there, so it fails.
