Microsoft MCSA 70-290 Exam Prep

Answer - C - To lock a user’s account after four consecutive failed logon attempts, set the Account lockout threshold value to 4.

Key Takeaway: Account lockout threshold determines the number of failed logon attempts that causes a user account to be locked out. You can set a value between 0 and 999 failed logon attempts. If you set the value to 0, the account will never be locked out. If you set the account lockout duration to 0, the account will be locked out until an administrator explicitly unlocks it.
