A group policy requires users in an organization to use strong passwords that must be changed every 15 days. Joe and Ann were hired 16 days ago. When Joe
logs into the network, he is prompted to change his password; when Ann logs into the network, she is not prompted to change her password. Which of the following
BEST explains why Ann is not required to change her password?

A.
Ann’s user account has administrator privileges.

B.
Joe’s user account was not added to the group policy.

C.
Ann’s user account was not added to the group policy.

D.
Joe’s user account was inadvertently disabled and must be re-created.

Explanation:
Group policy is used to manage Windows systems in a Windows network domain environment by means of a Group Policy Object (GPO). GPO’s include a number
of settings related to credentials, which includes password expiration. Because Anne was not prompted to change her password, it could only mean that her user
account was not added to the group policy.
Incorrect Answers:
A: Even if Ann’s user account has administrator privileges, if it was added to the group policy it would meet the requirements of the group policy.
B: If Joe’s user account was not added to the group policy, his account would not be required to meet the requirements of the group policy.
D: If Joe’s user account was inadvertently disabled and must be re-created, he would not be prompted to change his password at logon.
