CompTIA A+ Core 2 (220-1102) — Question 634

A customer reports high data usage on a smartphone that reaches its monthly data limit within the first week of each billing cycle. The customer uses the phone primarily for calls and SMS messages with minimal content streaming. A technician troubleshoots the phone and notices that both developer mode and installs from unknown sources are enabled. Which of the following should the technician check next?

Answer options

• A. Storage cache
• B. Malicious applications
• C. Privacy settings
• D. Permissions

Correct answer: B

Explanation

The correct answer is B, as enabling installations from unknown sources can lead to the presence of malicious applications that consume data. The other options, while relevant for general troubleshooting, do not directly address the potential cause of excessive data usage linked to unverified app installations.
