CompTIA A+ Core 2 (220-1102) — Question 632

A user's smartphone data usage is well above average. The user suspects an installed application is transmitting data in the background. The user would like to be alerted when an application attempts to communicate with the internet. Which of the following BEST addresses the user's concern?

Answer options

• A. Operating system updates
• B. Remote wipe
• C. Antivirus
• D. Firewall

Correct answer: D

Explanation

A firewall is designed to monitor and control incoming and outgoing network traffic based on predetermined security rules, which makes it ideal for alerting the user when an application tries to access the internet. Operating system updates, remote wipe, and antivirus solutions do not specifically address the issue of monitoring data transmission from apps.
