CompTIA 220-1201 Exam With Confidence Using Practice Dumps

A. Run the maintenance application:

Most modern printers include a built-in maintenance application that can calibrate the print heads and correct alignment issues. Running this tool is the first step to address misalignment.

Incorrect Options:

B. Clean the rollers: Cleaning rollers is typically done to resolve paper feed or jamming issues, not alignment problems.

C. Upgrade the firmware: While updating firmware is beneficial for performance improvements, it is not the first step for fixing alignment.

D. Reinstall the drivers: Misaligned printing is usually hardware-related, not a driver issue.

Key Takeaway: The maintenance application should be run first to resolve alignment issues in a newly installed printer.

A VLAN (Virtual Local Area Network) is the correct solution because it logically separates devices into different broadcast domains on the same physical switching infrastructure. In CompTIA A+ Core 1 (220-1201), VLANs are described as a way to segment a network for security, performance, and management—for example, isolating departments like Accounting and Customer Service so their traffic is separated. Devices assigned to different VLANs cannot communicate directly at Layer 2; communication between VLANs requires a Layer 3 device (such as a router or a Layer 3 switch) using inter-VLAN routing and appropriate access control. This effectively prevents unnecessary broadcast traffic from crossing department boundaries and helps enforce separation policies.

A VPN is used to create an encrypted tunnel over an untrusted network (commonly for remote access or site-to-site connectivity), not for internal departmental segmentation. DNS resolves hostnames to IP addresses and does not isolate networks. DHCP automatically assigns IP configuration (IP address, gateway, DNS servers), but it does not provide segmentation by itself. Therefore, implementing VLANs is the best way to separate the two departments’ networks.

The correct answer is A. RJ11.

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

RJ11 connectors are commonly used for telephone lines and data cables that use two pairs of wires (four wires total).

This connector is standard for analog telephone connections and DSL connections.

Why the other options are incorrect:

B. F-type: Used for coaxial cables, commonly in cable TV or broadband internet, not for two-pair data cables.

C. ST: A type of fiber optic connector, not used for copper two-pair wiring.

D. Molex: Primarily used for power connections in computer hardware, not for network or phone cabling.
