CompTIA 220-1201 Actual Questions

Virtual Desktop Infrastructure (VDI) delivers a desktop operating system hosted on a centralized server and streams the graphical user interface (GUI) to endpoint devices such as thin clients, zero clients, or standard PCs. According to CompTIA Core 1 (220-1201) virtualization objectives, VDI allows users to access their desktop environments remotely while all processing and data remain on the server.

Option A accurately describes this model: a GUI streamed from a server to thin clients. This approach improves centralized management, enhances security, and simplifies endpoint hardware requirements.

Provisioning a sandbox is an example of test or development virtualization, not desktop virtualization. High-performance workstations with a local OS are physical desktops, not VDI. Launching a virtual machine server on a hypervisor describes server virtualization, not desktop delivery.

CompTIA highlights VDI as a common enterprise solution that separates the desktop environment from the physical device, enabling flexibility, scalability, and centralized control.

If a hard drive is heavily fragmented, file read/write operations can take significantly longer, causing slow backup speeds. Defragmenting the drive organizes the data for more efficient access.

Why Not A (Replace the hard drive ' s USB cable): A faulty cable would typically cause disconnections or errors, not just slower speeds.

Why Not C (Update the storage drivers): This might help if the issue is with system drivers, but the described symptoms point to a fragmentation issue.

Why Not D (Compress the files): Compression reduces file size but does not address the root cause of the slow backups.

Comprehensive and Detailed Explanation

CompTIA A+ describes swollen or warped laptop chassis components as a classic symptom of a failing or swollen lithium-ion battery.

A swollen battery can:

Warp the keyboard

Push the bottom panel outward

Bend or distort the laptop frame

This is a safety hazard and requires immediate replacement.

Why the other answers are incorrect

B. RAM – Cannot cause physical warping.

C. Keyboard – May fail electronically, but does not physically deform itself.

D. HDD – Located away from the keyboard and cannot distort the chassis.

Final Answer: A

An SSD (Solid-State Drive) is the correct choice because it stores data using flash memory (NAND) and is commonly available in large capacities suitable for operating systems, applications, and mass storage. In CompTIA A+ Core 1 terms, SSDs contain no moving parts, which makes them faster and more reliable than mechanical drives for many workloads. They provide significantly improved read/write performance, lower latency, reduced heat output, and better shock resistance—important for both desktops and especially laptops. SSDs are also widely used in modern systems via SATA or NVMe (PCIe) interfaces, with NVMe offering the highest performance for large data transfers.

The other options do not match “flash memory”: DVD-RW is optical media with limited capacity and slower speeds, intended for removable storage rather than large-volume primary storage. An HDD can store large volumes of data but uses magnetic platters and moving heads, not flash memory. Tape is also magnetic media, typically used for backups and archival storage, and while it can store large amounts, it does not use flash and is designed for sequential access rather than fast random access. Therefore, SSD is the best answer.
