CompTIA A+ Core 2 (220-1002) — Question 312

Joe, a user, is unable to log into a laptop using his proper network credentials because of an incorrect username or password. However, Joe is able to log in without issue to a coworker's PC using his credentials. Which of the following is the MOST likely cause of the issue?

Answer options

• A. The administrator account was disabled during the installation of the OS
• B. The laptop was not joined to the domain when the OS was installed
• C. The laptop's hard drive was formatted with FAT32 during the OS installation
• D. The OS was not installed with the correct drivers for the laptop's input devices

Correct answer: B

Explanation

The correct answer is B because if the laptop was not joined to the domain, it would not recognize Joe's network credentials. The other options do not directly relate to the issue of domain authentication failure, as they pertain to different aspects of system configuration or hardware compatibility.
