CompTIA A+ Core 1 (220-1001) — Question 100

A user's smartphone has been slow recently. A technician sees the phone was purchased two months ago, and it is top of the line. About a month ago, a new OS update was installed. To address the issue, the technician runs a hardware diagnostic on the device, and it reports no problems. Which of the following is MOST likely the cause of the performance issue on the device?

Answer options

• A. Too many applications are running updates
• B. The device is currently running in airplane mode
• C. The internal memory is failing on the device
• D. The OS update is too resource intensive for the device

Correct answer: A

Explanation

The most likely cause of the performance issue is that too many applications are running updates, which can consume system resources and slow down the device. The other options are less plausible; airplane mode would not affect performance in this way, a new device is unlikely to have failing internal memory so soon, and while the OS update could be resource-intensive, the hardware diagnostic showed no problems.
