220-1202 CompTIA Exam Lab Questions

The amount of installed RAM is the key factor in determining whether a 64-bit OS is needed. A 32-bit operating system cannot effectively address more than 4GB of RAM. Since this system has 16GB of RAM, a 64-bit OS is required to utilize the full memory.

B. An Intel i7 CPU supports both 32-bit and 64-bit OS installations, so it alone doesn’t determine the need.

C. HDD size does not influence OS architecture selection.

D. Ethernet speed is a network consideration and not related to OS architecture.

The correct answer is A. .app, because macOS applications packaged as .app files are typically self-contained application bundles. This means that all required application files are stored within a single directory that appears as one file in Finder. When the .app file is moved to the Trash, the application is effectively removed from the system.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, macOS applications are commonly distributed as .app bundles, allowing for simple installation and removal. This design contrasts with Windows, where applications often install files across multiple directories and require uninstallers.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that dragging a .app file to the Trash is generally sufficient to uninstall the software, although some applications may leave behind preference files or caches. However, from an exam perspective, .app is the only option that supports this uninstall behavior.

The Mike Meyers / Mark Soper Lab Manual further clarifies that .msi and .exe are Windows formats, .rpm is used by Linux package managers, and .pkg installers often install system-wide components that require a formal uninstallation process.

Because .app files support simple drag-to-trash uninstallation, A is the correct answer.

3G networks generally do not provide the bandwidth required for seamless HD video streaming. With only two signal bars and a 3G connection, the mobile device likely cannot maintain the necessary data throughput, resulting in timeouts or buffering failures. This is a classic symptom of insufficient network speed or signal strength.

A. Lack of Wi-Fi may contribute, but the root cause is the low mobile bandwidth, not the Wi-Fi state.

B. A website subscription lapse would return an account error, not a timeout.

D. Full device storage can affect downloads but not streaming from the internet.

With integrated graphics, “VRAM” is often not dedicated memory on a discrete card—graphics may instead borrow system RAM. Quentin Docter explains this directly: if the video card is built into the motherboard, it “likely won’t have its own memory but will share system memory,” meaning the total system RAM is split between the OS and video usage. Docter then answers the key “where do I change this?” question: “Shared memory is configured in the system BIOS/UEFI,” and some BIOS/UEFI setups allow you to set aside a specific amount (example given: 512 MB) for video memory.

That is exactly why the machine can have plenty of DRAM yet fail a VRAM check: the BIOS/UEFI allocation for integrated graphics may be set too low. Adjusting BIOS/UEFI settings to reserve more memory for the integrated GPU is the most direct way to attempt meeting a VRAM requirement (when supported). Device Manager and System Configuration won’t change reserved video memory allocation, and “Virtual RAM” (paging) is unrelated to VRAM. Therefore, BIOS options is correct.
