220-1201 Exam Dumps - CompTIA A+ Core 1 Exam (2026)

The correct answer is A. Containers .

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

Containers provide lightweight, portable environments that package applications and their dependencies, allowing them to run consistently across multiple environments.

Containers are ideal for development teams because they require minimal underlying infrastructure, can be quickly deployed or destroyed, and isolate applications from the host system, making it easier to manage multiple applications simultaneously.

Why the other options are incorrect:

B. IaaS (Infrastructure as a Service): Provides virtualized hardware over the cloud but is more general-purpose; it includes virtual machines, storage, and networking, not minimal isolated application environments.

C. SaaS (Software as a Service): Provides fully managed software to end-users; not intended for deploying custom web applications by a development team.

D. Desktop virtualization: Provides virtual desktop environments to users; it does not provide a minimal, disposable platform for web application development.

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

The correct answer is B. Near-field communication (NFC) .

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

NFC is commonly used for secure access control. Many organizations implement NFC-enabled ID badges or mobile devices to unlock doors, gates, or secure areas.

The mobile device communicates over a very short range (a few centimeters) with a reader to authenticate the user.

Why the other options are incorrect:

A. Hotspot: Provides internet access, not physical building access.

C. Infrared scanner: While used in some legacy devices, it is not commonly implemented for secure mobile access.

D. Geolocation: Can provide location awareness but does not grant direct access to secure physical spaces.

The correct answer is B. Change the fuser temperature .

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

A laser printer fuses toner onto paper using heat and pressure. Thicker paper often requires a higher fuser temperature to properly adhere the toner.

If the output smudges on thick paper but prints fine on standard paper, adjusting the fuser temperature is the first step before performing more invasive maintenance or replacing parts.

Why the other options are incorrect:

A. Install a maintenance kit: Typically includes rollers, belts, and other parts; this is not the first action if the issue is temperature-related.

C. Clean the transfer roller: Cleaning may improve print quality, but smudging on thick paper usually relates to insufficient fusing heat.

D. Install an OEM toner cartridge: The issue is unlikely to be caused by non-OEM toner if standard paper prints correctly.

The correct answer is D. Dual channel .

In the CompTIA A+ Core 1 (220-1201) hardware objectives, memory bandwidth refers to the amount of data that can be transferred between RAM and the CPU in a given amount of time.

Dual channel memory architecture increases bandwidth by:

Allowing the memory controller to access two memory modules simultaneously

Effectively doubling the data transfer rate compared to single-channel configurations

Improving overall system performance, especially in memory-intensive tasks

Why the other options are incorrect:

A. CAS latency

CAS latency measures the delay before data is available after a request. Lower latency improves response time, but it does not significantly increase total bandwidth.

B. ECC

ECC (Error-Correcting Code) improves reliability by detecting and correcting errors, but it does not increase data transfer bandwidth.

C. High clock speed

Higher clock speed does increase bandwidth, but not as significantly as enabling dual channel , which allows parallel data transfer paths and provides a greater overall increase.

Final Answer: D. Dual channel

The correct answer is A. Adjust the SMTP server configurations for email .

Scan-to-email functionality on a multifunction printer relies on proper configuration of an SMTP (Simple Mail Transfer Protocol) server . The printer must know how to send outgoing email, which requires settings such as:

SMTP server address

Port number (commonly 25, 465, or 587)

Authentication credentials (username/password)

Encryption method (SSL/TLS if required)

If scan-to-email is not working, the most common cause is incorrect or missing SMTP configuration. Without this setup, the printer cannot send scanned documents via email.

Why the other options are incorrect:

B. Check the printer ' s IP address configuration

This ensures network connectivity, but since the printer is already in use and the issue is specific to email functionality, IP configuration is unlikely the root cause.

C. Install the printer ' s driver software on all computers

Drivers are needed for printing from computers, but scan-to-email is handled directly by the printer and does not depend on client-side drivers.

D. Configure user authentication settings for email access

While authentication may be required in some setups, it is part of the broader SMTP configuration. The primary and most direct fix is ensuring SMTP settings are correct.

Exam Tip (Core 1 220-1201):

Scan-to-email issues → Check SMTP settings first

Multifunction printers rely on network services (email protocols) , not just drivers

Final Answer: A. Adjust the SMTP server configurations for email

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.
