Note: Premium Questions for 220-1201 were last updated On Aug. 22, 2025 (see below)
An employee who travels worldwide wants a workstation to perform the same whether the workstation is in the corporate office environment or elsewhere. Which of the following should a technician implement?
A technician receives several complaints from the same office about VoIP calls sounding broken up, being difficult to hear, and having lagging audio. The technician arrives on-site and runs an internet speed test on several wired and wireless computers. Internet speed seems normal throughout the office. Which of the following should the technician do to fix the call issues?
Quality of Service (QoS) prioritizes VoIP traffic on the network, reducing jitter, latency, and packet loss to improve call quality.
From CompTIA A+ 220-1101 Official Study Guide, Objective 2.4 -- Network troubleshooting:
''Enabling QoS in the router ensures time-sensitive traffic, like VoIP, receives network priority, reducing dropped or lagging calls.''

A technician is having issues replacing a laptop's wireless card because the cover seems to be stuck Which of the following should the technician do next to troubleshoot this issued
A . Check the product manual for the procedure:
When hardware is not easily accessible, always consult the product manual for proper disassembly procedures. Forcing the cover can damage the laptop or void the warranty.
Product manuals often provide step-by-step instructions for safely accessing internal components.
Incorrect Options:
B . Use a pry tool to force the cover open: Forcing the cover can cause physical damage to the device.
C . Insert the wireless card into the M.2 slot: This step cannot be performed until the cover is properly removed.
D . Try to move the cover by sliding it in all directions: Randomly sliding the cover can cause damage if the correct removal method is not followed.
Key Takeaway: Always refer to the product manual to ensure safe and proper disassembly of laptop components.
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.
SIMULATION
A technician is installing a wireless access point and is required to run all cabling and make patch cords if necessary.
INSTRUCTIONS
Part 1
For each cable type, click the (+) to select the appropriate connector and tool.
part 2
An access point was moved and no longer has connectivity. Connect the access point, patch panel, and switch by clicking the (+) to select the appropriate cable end for each corresponding location to create a link.
