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

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 answer is D. Decreased burn-in .

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

Mini-LED displays use an array of tiny LEDs as a backlight for LCD panels.

Unlike OLED displays , which are susceptible to burn-in (permanent image retention when static content is displayed for long periods), mini-LEDs reduce the risk because the pixels themselves do not emit light individually and are less prone to permanent image retention.

Why the other options are incorrect:

A. Increased contrast: OLED typically provides better contrast because it can turn off individual pixels completely.

B. No backlight: Mini-LEDs still use a backlight, whereas OLEDs do not.

C. Improved viewing angle: OLEDs generally offer wider viewing angles than mini-LED LCDs.

Answer of both steps below.

A group of wires with different colors AI-generated content may be incorrect.

A screenshot of a computer AI-generated content may be incorrect.

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.

When a printout is being cut off, CompTIA A+ Core 1 (220-1201) troubleshooting emphasizes checking the simplest, most likely configuration mismatch first—the printer’s paper size/source settings. Even if the user physically loaded the correct paper, the print job can still be formatted incorrectly if the printer driver, application, or printer itself is set to use a different paper size or a different tray. If the printer thinks it is using a smaller paper size (or a tray configured for smaller paper), it may clip the printable area and truncate the image at the edges.

Changing tray settings (paper size and paper source) aligns the printer’s configuration with the actual media installed, which is a standard first-step for issues related to formatting, clipping, and page boundaries. Image quality (DPI) affects sharpness, not cropping. File type rarely causes consistent edge cutoff compared with page setup mismatches. Adjusting image size could work as a workaround, but CompTIA best practice is to correct the paper/tray and page setup settings first so all prints format properly without editing the document each time.

A printer with text boxes AI-generated content may be incorrect.

To ensure seamless connectivity during (and after) migrating an application server, the best DNS approach in CompTIA A+ Core 1 (220-1201) terms is to use a CNAME (Canonical Name) record, which creates an alias from one hostname to another. Instead of users connecting directly to a server’s changing hostname, they connect to a consistent service name (for example, app.company.com). That name can be configured as a CNAME pointing to the current host (such as server1.company.com). When the application is moved to a new server, the technician updates what the alias ultimately resolves to (or updates the target host’s A/AAAA record), and clients continue using the same familiar application URL/name—minimizing disruption and avoiding the need to reconfigure endpoints across devices.

The other record types are not designed for this purpose. TXT records store text-based information (often verification or policy data). SPF and DKIM are email authentication-related mechanisms (typically implemented via TXT records) used to validate authorized mail senders and message integrity—not application server migration. Because the goal is maintaining a stable name for a service while the underlying host changes, CNAME is the correct record type.

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.
