Older motherboards use 20-pin connectors, while newer power supplies use 24-pin connectors. An adapter resolves the compatibility issue cost-effectively.

Why Not A (Adjust the input voltage): Input voltage adjustment is unrelated to connector compatibility.

Why Not B (Install a modular power supply): While modular supplies are versatile, this doesn’t address the connector issue directly.

Why Not C (Rebuild the failed power supply): Rebuilding is costly and complex compared to using an adapter.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 3.4, power supply compatibility​.

A crimper is specifically used to attach RJ45 connectors to the ends of network cables. It pressesthe connector pins into the cable's wires, establishing a secure electrical connection. A punchdown tool is used for wiring patch panels or keystone jacks, not for attaching connectors.

Bluetooth is a wireless technology designed for short-range communication between devices. It is a classic example of a Personal Area Network (PAN), which supports communication between devices like smartphones, headsets, keyboards, and mice within a few meters. PANs are smaller in scope compared to LANs or WANs.

In networked print environments, print jobs are processed through a system service called the print spooler. CompTIA A+ stresses that when shared printers fail due to job overload, the problem often lies with a hung or overloaded spooler service, especially when multiple jobs are sent simultaneously. The spooler queues, organizes, and processes print jobs; if it becomes overwhelmed or corrupted, printing stops completely even though the network and printer hardware remain functional.

After verifying network connectivity—as the question states— the next logical and CompTIA-aligned troubleshooting step is to restart the spooler service (D). Restarting it clears stuck or corrupt jobs, reinitializes print processing, and restores functionality without requiring a full server reboot or reinstallation of drivers.

Rebooting the server (A) may work but is unnecessarily disruptive and affects multiple services. Reinstalling printer drivers (B) is only warranted for driver corruption issues and is not the first step for spooler congestion. Resetting the printer to factory defaults (C) erases settings and is far too drastic for a simple print queue issue.

Therefore, the most efficient and technically correct action is restarting the print spooler service, restoring printing immediately while maintaining normal server operations.

Adegraded RAID 1array usually meansone of the drives has failed or is failing. The correctnext step is torun diagnostics on each driveto identify the faulty one. RAID 1 uses mirroring, so one good drive should still contain all the data.

Option B:chkdsk checks file system integrity, not hardware drive health.

Option C:Rebuilding should only occurafteridentifying and replacing a faulty drive.

Option D:RAID 0 offers no redundancy and would destroy data in this context.

Objective 3.5: Given a scenario, troubleshoot problems related to storage devices.

Comprehensive and Detailed Explanation

CompTIA A+ describes swollen or warped laptop chassis components as a classic symptom of a failing or swollen lithium-ion battery.

A swollen battery can:

Warp the keyboard

Push the bottom panel outward

Bend or distort the laptop frame

This is a safety hazard and requires immediate replacement.

Why the other answers are incorrect

B. RAM – Cannot cause physical warping.

C. Keyboard – May fail electronically, but does not physically deform itself.

D. HDD – Located away from the keyboard and cannot distort the chassis.

Final Answer: A

CompTIA A+ highlights that swollen or expanding batteries especially lithium-ion batteries can physically warp the laptop chassis, keyboard, or trackpad. This happens when internal chemical reactions cause the battery to swell. Distorted keyboards, bulging trackpads, and lifted chassis panels are classic symptoms of battery failure.

RAM and HDD issues do not cause physical deformation. A broken keyboard may malfunction electronically, but it will not bulge upward unless forced by something underneath typically an expanding battery.

The A+ safety domain also warns technicians not to puncture swollen batteries and to replace them immediately due to fire hazards.

Therefore, a failing (swollen) laptop battery is the most likely cause.

ECC (Error-Correcting Code) RAM is commonly used in servers because it can detect and correct memory errors, providing greater stability and reliability for mission-critical environments.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.2 – Types of RAM:

“Servers often require ECC memory, which can detect and correct single-bit errors, preventing data corruption and increasing system reliability.”
