CompTIA A+ 220-1001/1002 Practice Test

Answer: B - A user has forgotten their Android mobile device password has tried to login too many times; as a result the device will lock until plugged into the computer to which it was last synced.

Key Takeaway:
On most Android devices, the first few incorrect passcodes result in the device locking for a limited amount of time. After this, the device must be plugged into the computer to which it was last synced in order to be unlocked. iPhones have a setting that allows you to set the phone to automatically erase after 10 unsuccessful attempts.
