Free Practice Questions for CompTIA 220-1201 Exam

A fileshare becoming slow over time and then failing completely strongly suggests storage subsystem degradation, often due to a failing RAID array. CompTIA A+ explains that slow file access is an early sign of a degraded array, and eventual unavailability indicates the array may have failed or entered a critical state.

Since the technician can still RDP into the server, the OS is functioning, meaning memory is likely not the issue. Network connectivity is sufficient for remote login. Backup integrity does not affect real-time file availability.

Thus, the next step is to check the RAID array status, which directly controls the server’s storage performance and availability precisely what CompTIA identifies as the primary point of failure in such scenarios.

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

A PoE injector is used to add power to an Ethernet cable, enabling the cable to deliver both power and data. This is crucial when connecting to PoE-enabled devices like IP cameras or wireless access points that are far from power outlets.

A valid public IP address must fall outside the private IP address ranges:

10.0.0.0 to 10.255.255.255

172.16.0.0 to 172.31.255.255

192.168.0.0 to 192.168.255.255

66.157.195.20 is outside these ranges, making it a public IP address.

Why Not A, C, D: These IPs fall within private IP address ranges.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.6, IP addressing​.

An uninterruptible power supply (UPS) protects systems against power outages by providing temporary backup power, giving users time to save data and safely shut down.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.3 – Power protection:

“A UPS supplies backup power to prevent data loss and hardware damage during outages or surges, ensuring system integrity.”

A managed switch provides advanced features such as traffic monitoring and VLAN configuration, allowing a technician to view network statistics for devices on the local subnet.

Why Not B (Router): A router connects different networks and directs traffic between them but does not provide detailed subnet-level statistics.

Why Not C (Access point): Access points provide wireless connectivity but lack traffic monitoring features.

Why Not D (Firewall): A firewall filters traffic but is not used for monitoring detailed statistics on a local subnet.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.6, network monitoring tools​.

The baseline documentation says the valid network range ends at 192.168.232.255, but the user’s gateway is 192.168.233.1, which is outside the permitted network range. CompTIA A+ emphasizes that devices must have a gateway inside their own subnet.

Given a mask of 255.255.255.0, the user’s subnet is 192.168.223.x, so the gateway must be in 192.168.223.x, not 192.168.233.x.

DNS settings are public and acceptable. The IP address and subnet mask are valid within the documented address space.

Therefore, the incorrect setting is the gateway, which prevents external routing. Correcting it resolves the connection issue, matching CompTIA’s routing and TCP/IP troubleshooting procedures.

USB-Cis a versatile connector capable oftransmitting data, video, audio, and power. With standards likeDisplayPort over USB-C or Thunderbolt 3/4, it can be used for external displays, file transfers, charging, and more all through one cable.

Option B (HDMI):Supports video and audio but not general data transfer.

Option C (DisplayPort):Similar to HDMI supports video/audio but not general file transfer.

Option D (VGA):Legacy analog video only no data or audio support.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.1: Identify common connector types.

Abulging tablet casingis a classic sign of aswollen lithium-ion battery, often caused by age, overheating, or overcharging. This is adangerous condition, as swollen batteries can rupture or catch fire. It also explains why the tablet only works when plugged in the battery is no longer holding a charge.

Option A:Power supply issues wouldn’t cause physical bulging.

Option B:A bad charge port wouldn’t cause screen damage or physical distortion.

Option D:A broken screen could cause display issues, but not the bulging chassis.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.4: Given a scenario, configure settings and use cases for laptops and mobile devices.

Amaintenance kitfor a laser printer often includesrollers, fuser, and other partsthat wear out over time. If the printer issmudging and misfeeding, it's a sign thatmultiple components are failing, which a maintenance kit is designed to resolve.

Option A (Fuser):May cause smudging if it's not heating correctly, but it won’t resolve paper misfeeds alone.

Option C (Corona wire):Can cause poor image quality if dirty but doesn’t affect paper feeding.

Option D (Toner cartridge):Can cause streaks if defective, but not paper feed issues.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.4: Given a scenario, install and configure printers.
