A user reports that their desktop PC does not turn on. Which of the following components would most likely cause the issue?
Correct Answer:
A
Comprehensive and Detailed In-Depth Explanation:
If a desktopfails to power on entirely, the most probable cause is afaulty Power Supply Unit (PSU). If there are no lights, fans, or POST beeps, the PSU may have failed, cutting off all power to the motherboard and components.
✑ Option B (GPU):Could prevent video output, but the system would still power on
and beep.
✑ Option C (RAM):Missing or faulty RAM would cause POST errors but not prevent startup entirely.
✑ Option D (CPU):A bad CPU may cause POST failure, but the system would usually at least power on.

A user's wireless headset shows a "connected" status when turned on, but the Bluetooth list on the user's phone shows that the headset is "not connected." Which of the following should the technician do?
Correct Answer:
C
Comprehensive and Detailed In-Depth Explanation:
When a device shows asnot connectedeven though it previously paired, the most effective action is tore-pair the devices. This resets the Bluetooth connection, clears any corruption in pairing profiles, and re-establishes communication.
✑ Option A:Entering a PIN is only relevant during initial pairing and may not be
prompted again.
✑ Option B:Turning off Wi-Fi doesn??t typically affect Bluetooth; they operate on similar frequencies but don??t conflict this way in normal use.
✑ Option D:If Bluetooth were disabled, the device wouldn??t appear at all, not just show as ??not connected.??

A technician receives a S.M.A.R.T. error on a PC. When the technician presses the Esc key, the PC continues to turn on without any further issues. Which of the following should the technician do next?
Correct Answer:
A
Comprehensive and Detailed Step-by-Step Explanation:
S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology):
S.M.A.R.T. is a monitoring system integrated into modern HDDs and SSDs that detects and reports on various indicators of drive health and reliability.
A S.M.A.R.T. error indicates that the drive is showing signs of impending failure, even if the PC continues to boot and work normally for the time being.
Next Steps:
The appropriate action is to replace the hard drive (HDD) because a S.M.A.R.T. error is an early warning of possible hardware failure. Ignoring the warning could result in data loss if the drive fails completely.
The technician should also back up the user's data immediately to avoid losing critical information.
Incorrect Options:
* B. Update the PC's BIOS: While keeping the BIOS updated is a good practice, it does not address the S.M.A.R.T. error, which is specific to the HDD.
* C. Close the ticket: Closing the ticket without resolving the issue would be improper, as the S.M.A.R.T. error is a hardware problem that needs to be addressed to prevent future data loss or downtime.
* D. Change the NIC: The NIC (Network Interface Card) is unrelated to the storage system and would not resolve a S.M.A.R.T. error.
Key Takeaway:
A S.M.A.R.T. error is a critical indicator of HDD health issues, and the drive should be replaced as soon as possible. Backing up data is also essential.

A customer reports a problem connecting to network resources. After asking open-ended questions, the technician determines the issue likely exists on the remote server. Which of the following should the technician do next?
Correct Answer:
B
After determining the issue is likely on the remote server, the technician should test the theory to confirm the root cause before proceeding.
Why Not A (Document the findings): Documentation comes after confirming the issue. Why Not C (Gather information): Information gathering is already completed.
Why Not D (Establish a plan of action): This is done after confirming the issue. CompTIA A+ Exam Reference: Core 2 (220-1102), Section 3.1, troubleshooting methodology.

A user prints a job from a laser printer. The user wipes the page, and the words and images come off of it. The technician replaces the toner cartridge, but the issue persists. Which of the following components should the technician replace next?
Correct Answer:
A
Comprehensive and Detailed In-Depth Explanation:
Inlaser printers, thefuser unitis responsible formelting the toner onto the paperusing heat and pressure. If the toner rubs off easily, it's a clear sign thefuser is failing or not heating properly. Replacing the fuser will ensure the toner bonds correctly to the paper.
✑ Option B (Drum):Transfers the image, but doesn't fuse the toner.
✑ Option C (Developer roller):Applies toner to the drum — wouldn??t cause toner to rub off.
✑ Option D (Discharge lamp):Prepares the drum for a new image; not related to
toner adhesion.
