220-1201 Exam Dumps - CompTIA A+ Questions and Answers

The correct answer is B. Inspect and replace the printer rollers.

According to CompTIA A+ Core 1 220-1201 objectives under Printers:

Frequent paper jams with no visible obstruction are often caused by worn or dirty feed rollers, which fail to grip and feed paper properly.

Inspecting and replacing the rollers ensures smooth paper feeding and prevents repeated jams, particularly in high-use network printers.

Why the other options are incorrect:

A. Check for firmware updates: Firmware updates address software or functionality issues, not mechanical paper feeding problems.

C. Reseat the fuser assembly: Fuser issues typically cause smudging or incomplete toner adhesion, not paper jams.

D. Clean the corona wire: The corona wire affects toner adhesion and print quality, not paper feeding.

The correct answer is B. USB.

In the CompTIA A+ Core 1 (220-1201) objectives under mobile devices and connectivity methods, tethering refers to sharing a mobile device’s internet connection with another device such as a laptop. There are several tethering methods, including USB tethering, Bluetooth tethering, and Wi-Fi hotspot.

USB tethering is considered the most stable and reliable (tethered) connection because:

It uses a physical cable connection, eliminating wireless interference.

It provides consistent bandwidth and low latency.

It also charges the phone while connected, which is an added benefit.

It is less prone to disconnections compared to wireless methods.

Why the other options are incorrect:

A. Bluetooth

Bluetooth tethering is slower and less stable due to limited bandwidth and susceptibility to interference. It is not ideal for high-performance or stable connections.

C. Hotspot

A mobile hotspot uses Wi-Fi, which is wireless, not tethered. While convenient, it is less stable than a wired USB connection and can be affected by interference and signal range.

D. NFC

NFC (Near Field Communication) is used for very short-range communication like payments or quick pairing. It is not used for maintaining a continuous network connection.

Final Answer: B. USB

The correct answer is C. ECC (Error-Correcting Code).

In the CompTIA A+ Core 1 (220-1201) hardware objectives, RAM types and features include technologies designed to improve reliability and data integrity.

ECC memory is specifically designed to detect and correct data errors (faults) in memory automatically. It uses additional bits to store error-checking information, allowing the system to:

Detect single-bit and some multi-bit errors

Automatically correct errors without system interruption

Improve system stability, especially in servers and critical systems

This makes ECC the best choice for recovering from data faults.

Why the other options are incorrect:

A. Capacity

Capacity refers to how much data the RAM can hold (e.g., 8GB, 16GB). It has nothing to do with error detection or correction.

B. Speed

Speed (measured in MHz or MT/s) affects performance but does not provide any fault recovery capability.

D. DDR

DDR (Double Data Rate) refers to the generation/type of RAM (e.g., DDR3, DDR4, DDR5). It improves performance but does not handle errors.

E. Parity

Parity memory can detect errors but cannot correct them. Since the question specifically asks for recovery from faults, ECC is the correct answer because it both detects and corrects errors.

Final Answer: C. ECC

The correct answer is C. Virtualization.

According to CompTIA A+ Core 1 220-1201 objectives under Networking and Cloud/Virtualization Concepts:

Virtualization allows a single physical server to host multiple virtual machines (VMs), each running its own operating system and applications.

This reduces hardware costs because fewer physical servers are required to run multiple workloads, and it improves resource utilization, scalability, and management.

Why the other options are incorrect:

A. Containerization: Optimizes application deployment by packaging applications and dependencies, but containers share the host OS kernel and are not full OS instances.

B. Cloud computing: Refers to delivering computing services over the internet; it can use virtualization but is broader and not specifically focused on reducing physical hardware.

D. Remote desktop services: Provides remote access to desktops or applications; it does not reduce hardware requirements for hosting multiple OS environments.

The correct answer is A. Loopback plug.

According to CompTIA A+ Core 1 220-1201 objectives under Networking:

A loopback plug is used to test a network interface card (NIC) port by sending a signal out of the port and back into the same port, verifying that the NIC can send and receive data properly.

This is a common diagnostic tool when troubleshooting network connectivity issues on individual devices.

Why the other options are incorrect:

B. Toner probe: Used for tracing and locating cables, not for testing NIC ports.

C. Cable tester: Checks the integrity of network cables but does not verify NIC send/receive functionality.

D. Network tap: Passively monitors network traffic but does not test the NIC port itself.

Because the smudges are not in the original document, CompTIA A+ troubleshooting logic indicates the problem is occurring inside the print process, not in the application or file. For laser printers, smudging commonly points to an issue with the imaging components—especially the drum/photoconductor unit (and sometimes the fuser). A+ Core 1 (220-1201) printer troubleshooting emphasizes starting with the most likely, easiest-to-verify causes before replacing parts. Inspecting the drum is a diagnostic step that can reveal visible defects such as scratches, toner buildup, contamination, or worn surfaces that cause toner to transfer incorrectly, leading to streaks or smears on output.

Replacing the toner (D) is a corrective action and may be unnecessary if the drum is damaged. Changing paper type (A) can help with some issues (like poor fusing or humidity-related problems), but it’s less directly tied to consistent smudges caused by the imaging process. Firmware updates (C) are rarely the first step for print-quality defects; they’re more relevant to compatibility, bugs, or feature issues—not physical smearing. Therefore, inspecting the printer drum first best matches A+ methodology and common laser printer failure points.

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.

The correct answers are E. NFC and F. Location services.

According to CompTIA A+ Core 1 220-1201 objectives under Mobile Devices and Security:

NFC (Near-Field Communication): Enables the device to communicate with contactless payment terminals, which is essential for detecting nearby stores that accept contactless payments.

Location services: Allows the application to determine the user’s geographic location so it can provide notifications only when the user is near a participating store.

Why the other options are incorrect:

A. MDM (Mobile Device Management): Manages device policies but does not enable location-based notifications or contactless payments.

B. Contact syncing: Synchronizes contacts; unrelated to payment notifications.

C. Bluetooth: Can be used for some proximity services, but NFC is required for contactless payment detection.

D. Hotspot: Provides internet access; not required for proximity detection in this context.

The correct answer is D. Verify the audio output assignment.

According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Troubleshooting:

HDMI carries both video and audio signals. If video displays correctly but audio is not heard, it is often because the computer is still outputting sound to its internal speakers rather than the HDMI-connected device.

The user should check the audio output settings in the operating system and ensure the HDMI device (TV or projector) is selected as the audio output device.

Why the other options are incorrect:

A. Adjust the volume settings: Volumes are already at 50%, so adjusting them will not solve the problem if the audio output is assigned incorrectly.

B. Swap the HDMI cable: The video is working fine, so the cable is likely functional.

C. Reinsert the HDMI cable: Unlikely to resolve audio assignment issues if the connection is already working for video.

The correct answer is A. Better compatibility.

According to CompTIA A+ Core 1 220-1201 objectives under Software Troubleshooting and Virtualization:

Application virtualization allows applications to run in an isolated environment on a client device without being installed directly on the operating system.

This improves compatibility, as applications can operate regardless of OS differences, avoiding conflicts with other installed applications or system configurations.

Why the other options are incorrect:

B. Reduced network latency: Application virtualization does not inherently reduce network latency; network performance depends on connectivity.

C. Secure telnet access: Telnet is unrelated to application virtualization.

D. Metered utilization: Metering refers to cloud service usage or billing, not a benefit of application virtualization itself.

The correct answer is D. Restart the device.

According to CompTIA A+ Core 1 220-1201 objectives under Mobile Devices and Security:

Warning messages like this can be caused by malicious pop-ups or temporary software glitches. Restarting the device is the safest and quickest first step to clear temporary processes, refresh the system, and remove transient malware or pop-up overlays.

This approach addresses the issue without risking data loss or unnecessary downtime.

Why the other options are incorrect:

A. Force close all running applications: May help if a specific app is causing the pop-up, but restarting achieves this more reliably and fully resets background processes.

B. Replace the tablet with a newer device: Unnecessary and costly for a potentially temporary software issue.

C. Reset the device to default settings: This is a last-resort action, as it erases personal data and settings; it is not the first step.

The correct answer is A. Duplex.

In the CompTIA A+ Core 1 (220-1201) exam objectives under printer settings and configuration, duplex printing refers to printing on both sides of the paper automatically.

Using duplex printing is the best way to reduce resource consumption because:

It cuts paper usage in half, which is the primary resource being conserved.

It is ideal for multi-page documents and multiple copies.

It reduces physical storage and handling requirements.

Why the other options are incorrect:

B. Orientation

Orientation (portrait or landscape) changes the layout of the document but does not reduce resource usage.

C. Tray settings

Tray settings determine which paper tray is used (e.g., plain paper, letterhead), but they do not impact resource consumption.

D. Quality

Print quality (draft, normal, high) may affect ink/toner usage, but it does not reduce paper consumption as effectively as duplex printing, which is the main resource concern in this scenario.

Final Answer: A. Duplex

CompTIA A+ Core 1 (220-1201) display technology objectives emphasize that contrast ratio is strongly influenced by how well a screen can produce true black. OLED (Organic Light-Emitting Diode) panels are known for the highest contrast ratios because each pixel is self-emissive—meaning it generates its own light. When an image requires black, OLED can turn individual pixels completely off, producing near-perfect black levels and extremely high (often “infinite”) contrast in practical terms.

By comparison, LCD panels require a backlight, so black areas still allow some light leakage through the liquid crystal layer, reducing contrast. LED in this context is typically an LED-backlit LCD, not a fundamentally different pixel technology; it improves brightness and efficiency but still relies on backlighting, so contrast is limited by backlight bleed and panel design. QLED is also a type of LCD technology that uses a quantum dot layer to enhance color and brightness, but it still uses a backlight, so it cannot match OLED’s per-pixel shutoff for black levels. Therefore, OLED is the best choice for the highest contrast ratios.

The correct answer is C. Synchronized system clocks.

According to CompTIA A+ Core 1 220-1201 objectives under Networking and Server Services, NTP (Network Time Protocol) is used to synchronize the clocks of computers across a network to a common time source. This is critical for:

Ensuring accurate timestamps for logs and events.

Coordinating scheduled tasks across multiple systems.

Preventing authentication issues in environments that rely on time-based credentials (e.g., Kerberos).

Why the other options are incorrect:

A. Defined network transport protocols: NTP itself is a protocol that uses UDP, but its primary purpose is not defining transport protocols.

B. Enabled print services on the server: NTP does not relate to printing.

D. Defined server options in DHCP: NTP may be referenced by DHCP options, but the act of adding NTP to a server is focused on time synchronization, not DHCP configuration.

A hypervisor is software or firmware that allows multiple operating systems (virtual machines) to run on a single physical host. It manages the allocation of resources and isolation of each VM.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 – Virtualization concepts:

“A hypervisor is the key component of virtualization, enabling a physical server to host multiple virtual machines (VMs), each with its own OS and resources.”
