CompTIA A+ Core 2 (220-1102) — Question 240

A technician installed Windows 10 on a workstation. The workstation only has 3.5GB of usable RAM, even though the technician installed 8GB. Which of the following is the MOST likely reason this system is not utilizing all the available RAM?

Answer options

• A. The system is missing updates.
• B. The system is utilizing a 32-bit OS.
• C. The system's memory is failing.
• D. The system requires BIOS updates.

Correct answer: B

Explanation

The correct answer is B, as a 32-bit operating system can only address up to 4GB of RAM, limiting usable memory. The other options, such as missing updates, failing memory, or needing BIOS updates, do not directly cause the limitation of usable RAM to this extent.
