Exam 220-1202 Topic 1 Question 61 Discussion

Password complexity rules and account lockout thresholds are controlled through security policies, which are managed via Group Policy on a local system using the Local Group Policy Editor (gpedit.msc). The All-in- One guide explains that Windows security policies can enforce rules like "forcing anyone who logs on... to use a password that's at least eight characters long," and that these are configured via policy tools. It further highlights that "The Group Policy Editor (gpedit.msc) includes the same items as Local Security Policy...
plus many other policies," making gpedit the best match when the exam asks how to edit these settings.
Mike Meyers' Lab Manual repeats this exact exam-relevant point: gpedit includes the security policy settings and is the tool to look for on the A+ exam when the question is about configuring password policy and account policies.
The other snap-ins don't fit: Task Scheduler manages scheduled tasks, Local Users and Groups manages accounts/groups (not password policy enforcement rules), and Performance Monitor tracks performance.
Therefore, gpedit is correct.
