CompTIA Security+ (SY0-501) — Question 794

Joe, an employee, wants to show his colleagues how much he knows about smartphones. Joe demonstrates a free movie application that he installed from a third party on his corporate smartphone. Joe's colleagues were unable to find the application in the app stores. Which of the following allowed Joe to install the application? (Choose two.)

Answer options

• A. Near-field communication.
• B. Rooting/jailbreaking
• C. Ad-hoc connections
• D. Tethering
• E. Sideloading

Correct answer: B, E

Explanation

Joe was able to install the application because of rooting/jailbreaking, which allows users to bypass restrictions and install apps from sources other than official app stores. Sideloading also enabled him to manually install the app from a third-party source. The other options, like Near-field communication, Ad-hoc connections, and Tethering, do not pertain to the installation of applications from outside app stores.
