At ValidExamDumps, we consistently monitor updates to the CompTIA 220-1201 exam questions by CompTIA. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the CompTIA A+ Certification Exam: Core 1 exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by CompTIA in their CompTIA 220-1201 exam. These outdated questions lead to customers failing their CompTIA A+ Certification Exam: Core 1 exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the CompTIA 220-1201 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
A technician is troubleshooting a computer that has random BSOD alerts and intermittently freezes during normal use. Performance degrades as the day goes on. No new software or hardware changes have been implemented. Freezing occurs under performance-intensive operations. Which of the following hardware components is most likely at fault?
Comprehensive and Detailed Step-by-Step
Random BSODs (Blue Screen of Death), intermittent freezing, and degraded performance under load are common symptoms of failing or faulty RAM (Random Access Memory). Here's the reasoning:
RAM Module (Correct Answer):
Faulty or failing RAM can cause random BSODs due to memory errors when the system attempts to read or write to corrupted memory locations.
Intermittent freezing, especially under performance-intensive operations, can occur because the CPU relies heavily on RAM for active processing tasks.
Over time, heat generated during usage can exacerbate RAM instability, leading to progressively worse performance throughout the day.
Solution: The technician should run a memory diagnostic tool, such as Windows Memory Diagnostic or MemTest86, to confirm if the RAM is at fault.
Incorrect Options:
A . Video Card: A faulty video card can cause graphical glitches, screen artifacts, or crashes, but it is unlikely to cause system-wide performance degradation and random freezing under normal operations unless the issue is specific to GPU-intensive tasks (e.g., gaming or video rendering).
B . HDD: A failing hard drive can cause system slowdowns and freezing, but it typically produces other symptoms such as read/write errors, boot failures, or clicking sounds. HDD issues do not usually cause BSODs unless critical system files are corrupted.
D . TPM (Trusted Platform Module): A TPM is a hardware-based security module used for encryption and secure authentication. It does not affect performance or cause BSODs or freezing under normal operation.
Key Takeaway:
The symptoms described (random BSODs, intermittent freezing, and degraded performance under load) are most likely caused by faulty or failing RAM. Memory diagnostic tools should be used to confirm the issue.
Each lime a user ties to print, the paper becomes stuck at the last stage of the print job and the user has to poll me paper out of the printer. Which of the following is me most likely cause?
If paper gets stuck at the last stage of printing, the rollers responsible for moving the paper through the printer are likely worn out or dirty.
Why Not B (Tray assembly): The tray assembly manages paper loading, not feeding during the print process.
Why Not C (Toner): Toner is unrelated to paper jams.
Why Not D (Printhead): Printheads manage ink/toner distribution, not paper movement.
CompTIA A+ Exam Reference: Core 2 (220-1102), Section 4.6, printer troubleshooting.
A user brings a laptop to work every morning, correctly seats it in the docking station and then opens the laptop to begin work with no issues After the user left the laptop at home during a two-week vacation the laptop is no longer working. Upon returning to the office, the user reports that the keyboard and display are no longer working Which of the following should the technician ask the user to do first?
Reasoning: Many docking stations provide power and functionality only when the laptop is properly powered on. If the laptop was powered off (e.g., during the vacation), docking it will not automatically turn it on. The technician should first ensure the laptop is powered on by pressing the power button.
This is a common troubleshooting step when laptops in docking stations appear non-functional.
Relevance to CompTIA A+ Core 1: This falls under Objective 5.2, which covers diagnosing and resolving common laptop and mobile device issues.
Why the Other Options Are Incorrect:
A . Ensure the docking station is plugged in:
While ensuring power to the docking station is important, the scenario specifies that the issue occurred after a vacation. The likelihood of the docking station losing power coincidentally during the vacation is low. Verifying the laptop's power state should be the first step.
C . Plug the laptop in and let it charge overnight:
There is no indication the laptop's battery is drained. While charging could resolve a dead battery, the user is more likely experiencing an issue where the laptop is powered off but docked, so charging overnight is not the best first step.
D . Connect the laptop directly to the network:
A network connection will not resolve the primary issue of the keyboard and display not working. Addressing the laptop's power state is a higher priority.
Practical Example:
If a user returns from a vacation and places a powered-off laptop into a docking station, it may not automatically power on. Pressing the power button ensures the laptop is operational and communicating with the docking station.

A customer needs to install a new printer in their network. The customer reports that users had intermittent connectivity issues with previous printers. Which of the following should the technician configure on the new printer to prevent this issue?
Comprehensive and Detailed Explanation From Exact Extract:
Intermittent connectivity issues with network printers are commonly caused by changing IP addresses when using DHCP. Assigning a static IP address ensures that the printer is always reachable at the same IP address by client machines.

Which of the following should a technician use to terminate a Cat 6 cable to a patch panel?
Comprehensive and Detailed Explanation From Exact Extract:
A punchdown tool is specifically used to insert wires into a punchdown block in patch panels, which is typical for Cat 6 and similar cabling. It ensures a secure and correct connection by pushing the wire into a metal groove that slices the insulation.
