Free 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?
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.
The smartphone's data usage notification settings were mistakenly configured to alert at lower thresholds.
These are typical behaviors for a smartphone approaching the end of its service life.
