CompTIA Updated 220-1201 Exam Questions and Answers by lea

The correct answer is D. Replace the drive with a cold-swappable drive .

According to CompTIA A+ Core 1 220-1201 objectives under Storage and RAID:

RAID 5 provides both data striping and parity for fault tolerance, but if the RAID controller does not support hot swapping, replacing a failed drive while the system is running is not possible.

Cold-swappable drives are designed to be safely removed and replaced when the system is powered down, which allows maintenance without damaging the array or system.

Why the other options are incorrect:

A. Update the RAID controller firmware to support hot swapping: Firmware updates may add hot swap functionality, but this is not guaranteed and may require a system reboot.

B. Implement a software-based RAID solution: Software RAID requires a system reconfiguration and downtime; it does not immediately resolve the degraded RAID 5 array.

C. Change the drive during off-peak hours: While feasible, this is essentially the same as using a cold-swappable drive but is less precise; using cold-swappable drives ensures safe replacement without downtime considerations.

The correct answer is B. Moving to a supported system under a Type 2 hypervisor .

In the CompTIA A+ Core 1 (220-1201) objectives, virtualization is a key concept for maintaining compatibility with legacy systems. A Type 2 hypervisor (hosted hypervisor) runs on top of an existing operating system and allows users to run a virtual machine (VM) with an older OS.

This solution is ideal because:

It allows the legacy application to run in its required OS environment .

It avoids replacing the application (which could cause data loss or compatibility issues ).

It is cost-effective , as it uses existing hardware.

It minimizes user disruption , since users can continue using the application within a VM.

Why the other options are incorrect:

A. Setting up a bare-metal hypervisor

A Type 1 (bare-metal) hypervisor is more complex, costly, and disruptive. It typically requires dedicating hardware and is not ideal for a single department use case.

C. Upgrading to an alternative product and importing the data

Although this may be a long-term solution, it involves higher cost, potential data loss, retraining, and disruption .

D. Uploading the database to a private cloud

This does not solve the compatibility issue of the legacy application with the new OS.

Final Answer: B. Moving to a supported system under a Type 2 hypervisor

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.

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.
