Question:
What is a recommended best practice for a technician who must perform tasks that require administrative access?

• Ask the current user to log off, restart the computer, and then log in with the administrator account.
• Prevent the computer from contacting the network authentication server by disabling the network card and then log in with an administrator account.
• Log off the computer and then log in with an account with administrator privileges.
• Use a standard account with limited permissions, and then use the Run as Administrator option to perform the task that requires elevated privileges.

Explanation: In addition to nontechnical users having a standard user account, it is also a best practice to make technical staff use a limited account. Then when an administrative task is needed, the technician uses the Run as Administrator option and provides the appropriate credentials of an account that has elevated credentials for the one task.
