220-1201 CompTIA A+ Core 1Exam (2025) Questions and Answers

To change adomain passwordfrom a remote location, the system must communicate with thedomain controller. Since the user is working from home, they need toconnect to the corporate VPNto establish that secure connection. Without it, the password change cannot be authenticated.

Option A:Restarting will not resolve the lack of connection to the domain controller.

Option C:Resetting the password in AD could help, but doesn’t let the user reset it themselves.

Option D:The user may already be on Wi-Fi; the issue is with connecting to thecorporate network, not local.

If a print spooler crashes specifically with one application and no issue occurs on other systems, the most likely root cause is a bug within that specific application. Restarting the spooler and reinstalling drivers resolves system-wide or hardware-related issues—not app-specific failures. This indicates the application may be sending malformed print data.

Fiber optic connections provide the highest data transfer rates and symmetrical upload and download speeds. This makes fiber the ideal choice for applications requiring high-speed connectivity, such as video conferencing, large file transfers, and cloud-based workflows.

Comprehensive and Detailed Step-by-Step Explanation:

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.

Security groups are used to manage access permissions to network resources, ensuring only authorized HR department members can access the shared materials.

Why Not B (Audit logs): Audit logs monitor activity but do not restrict access.

Why Not C (Time-of-day access): Time-of-day access limits when users can access resources but doesn’t specify user permissions.

Why Not D (Print server): A print server manages print jobs but does not control file access.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 2.5, access control and permissions​.

Reasoning: Projectors have air filters that prevent dust from entering the internal components. A clogged filter can cause the projector to overheat, resulting in shutdowns and even strange smells due to overheating components. Cleaning the filter is a standard troubleshooting step when projectors exhibit overheating symptoms.

Why the Other Options Are Incorrect:

A. Replace the bulb:

While a failing bulb may eventually cause issues, it would not typically result in a strange smell or repeated shutdowns after a fixed period. Bulb issues usually manifest as dim or flickering images.

B. Check the projector configuration:

Configuration settings, such as resolution or input options, would not cause overheating or shutdowns. This option does not address the described symptoms.

D. Adjust the gamma settings:

Gamma settings affect display brightness and contrast but have no impact on overheating or strange smells.

Practical Example:

Dust accumulation in projectors is a common issue, especially in environments with poor air circulation. A clogged filter causes restricted airflow, leading to overheating and automatic shutdowns to protect internal components. Cleaning the filter typically resolves this issue.

The degraded status on Server 2 indicates a RAID-5 issue, typically due to a failed or failing drive. In RAID-5 configurations, when one drive fails, the system can still operate but with reduced performance as parity data is used to rebuild missing data on-the-fly.

Recommended Replacement Drive:

To minimize performance degradation, the replacement drive should be:

SAS HDD with the same specifications (64KB stripe size, no read-ahead, and write-back policy).

Matching the configuration exactly ensures seamless integration and optimizes recovery speed in the RAID-5 array.

In RAID-5, degraded performance is expected when one drive fails, as parity data needs to rebuild missing information during each read/write process. Replacing the failed drive restores the RAID array to optimal status, reducing the load on existing drives and returning the system to normal read/write performance. The write-back policy and disabled disk cache settings are designed to reduce latency and increase efficiency, essential for handling real-time applications.

Looking at the network configurations and outputs from both PCs and servers, here are the possible issues and solutions:

1. PC 1

Issue: The IP address for PC1 is 192.168.1.1, which conflicts with Server 1 (which also uses 192.168.1.1).

Solution: Change the IP address on PC1 to a unique one within the range, like 192.168.1.3.

2. PC 2

Issue: PC 2 is configured with 192.168.1.2, which conflicts with Server 2 that has the same IP address.

Solution: Update the IP address on PC 2 to something unique, like 192.168.1.4.

3. Server 1

Issue: The IP address for Server 1 is 192.168.1.1, which conflicts with PC1.

Solution: Since Server 1 and PC1 are using the same IP address, change one of them. For Server 1, you could change the IP address to 192.168.1.5.

4. Server 2

Issue: Server 2 is using the IP address 192.168.1.2, which conflicts with PC2.

Solution: Update Server 2 to use a different IP address, such as 192.168.1.6.

General Remediation:

The primary problem here is overlapping IP addresses, leading to connectivity issues. Each device on the network must have a unique IP address. After making these changes, ensure that all devices can communicate properly by testing the connection between devices and verifying they can access shared resources.
