Which user account has System Administrator privileges from the SIDs list extracted by Peter?

• A. J. Doe
• B. A. Smith
• C. K. Lee
• D. F. Chang

Answer: (D)

System Administrator privileges come from being a member of the built-in Administrators group (or being the built-in Administrator account). In Windows, each account or group has a SID, and certain SIDs identify privileged principals. The Administrators group has the group SID associated with it, and the built-in Administrator account has a user SID with the corresponding privileged RID. When you review a list of SIDs, you look for the SID that maps to that admin principal. In this scenario, the SID that matches the Administrators group or the Administrator account belongs to F. Chang, which is why that user has System Administrator privileges. The other SIDs correspond to non-admin users or groups, so they don’t have those elevated rights.
