CompTIA A+ Core 1 (220-1001) — Question 77

Which of the following resources is the MOST critical when using cloud file-storage synchronization applications?

Answer options

• A. Disk speed
• B. I/O bandwidth
• C. RAM utilization
• D. CPU utilization

Correct answer: B

Explanation

I/O bandwidth is the most critical resource because it directly affects the speed and efficiency of data transfer between the local system and the cloud storage. While disk speed, RAM utilization, and CPU utilization are important, they do not have as significant an impact on the overall performance of cloud file synchronization as I/O bandwidth does.
