CompTIA A+ 220-1102 Practice Question
A user reports that their smartphone is exhibiting unexpected application behavior, high network traffic, and received a data usage limit notification despite normal use. The user also mentions installing an application recently from a source outside the official app store to get premium features for free. As a technician, what is the most likely cause of these symptoms?
These are typical behaviors for a smartphone approaching the end of its service life.
The smartphone's data usage notification settings were mistakenly configured to alert at lower thresholds.
The symptoms are due to a legitimate software update from the smartphone's official vendor.
The device has potentially been compromised due to jailbreaking or root access to install unauthorized applications.
