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

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 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.

In CompTIA A+ Core 1 (220-1201) cloud concepts, the key differentiator between cloud deployment models is where the service is hosted and who owns/uses the underlying infrastructure. If a company’s directory services server (for example, a domain controller providing authentication/authorization and centralized identity management) is located on premises, that points to infrastructure that is owned and operated by the organization for its own internal use. This aligns best with a private cloud model, which is defined as cloud resources dedicated to a single organization and can be implemented on-premises (internally hosted) or in a dedicated off-site environment.

It is not a public cloud because public cloud services are hosted by a third-party provider and shared across multiple customers. It is not hybrid cloud because hybrid requires a mix of on-prem resources and public cloud resources working together (the question only specifies on-prem). It is not community cloud because that involves shared infrastructure among multiple organizations with common needs.

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.

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 B. Reconnect the wireless antennas.

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

Many laptop wireless antennas are routed through the display assembly to provide optimal Wi-Fi and Bluetooth signal strength.

When replacing a laptop display, it is essential to disconnect and then reconnect the wireless antennas to ensure proper connectivity.

Failing to reconnect these antennas can result in weak or no wireless signal.

Why the other options are incorrect:

A. Reattach the heat sinks: Heat sinks are part of the CPU/GPU cooling assembly and are unrelated to replacing the display.

C. Install a new CPU fan: CPU fans are part of the cooling system, not the display assembly.

D. Reset the BIOS to default settings: Not required for physically replacing the display; the BIOS retains settings independently of display hardware.

The correct answer is D. Router.

According to the CompTIA A+ Core 1 (220-1201) objectives for Networking, routers are devices that operate at Layer 3 (Network layer) and are primarily used to connect multiple networks, including LANs, WANs, and the Internet. Routers use IP addressing to determine the best path for forwarding packets between networks.

Why the other options are incorrect:

A. Controller: Generally refers to a device that manages a network or hardware component but does not inherently connect different networks.

B. Bridge: Connects two segments of the same network, not different networks, and operates at Layer 2 (Data Link layer).

C. Hub: Connects devices within the same network segment, simply repeating signals, and does not perform routing between networks.

The correct answer is D. Injector.

Power over Ethernet (PoE) allows network cables to carry electrical power to devices such as wireless access points, IP cameras, and VoIP phones, eliminating the need for separate power supplies. According to the CompTIA A+ Core 1 220-1201 objectives under Networking, PoE can be implemented in the following ways:

PoE-enabled switches: Switches that can supply power directly over the Ethernet ports.

PoE injectors: Devices that add power to an existing Ethernet connection when the switch or router does not provide PoE.

Why the other options are incorrect:

A. Modem: A modem connects a network to the Internet but does not provide PoE functionality.

B. Range extender: Extends the range of a wireless network; does not supply power over Ethernet.

C. Media converter: Converts one type of network media to another (e.g., fiber to copper) but does not implement PoE.

Therefore, when a switch does not natively provide PoE, a PoE injector is the standard solution to add power to the Ethernet line.
