Which term describes groups that automatically update membership based on conditions?

• A. Hierarchical Structure
• B. Static Groups
• C. Dynamic Groups
• D. Primary Group

Answer: (C)

Dynamic groups are sets whose members are determined by rules and updated automatically as those rules are met or changed. In practice, you define criteria—such as a user’s department, operating system, or location—and anyone who satisfies those conditions is added to the group, while anyone who no longer fits the criteria is removed. This keeps group membership current without manual updates and makes applying policies or access rights easier and more reliable, especially in changing environments where people move roles or devices change attributes.

The other terms don’t describe automatic, condition-based membership. A hierarchical structure refers to nesting groups within groups, not how members are assigned. Static groups require manual adding and removing of members. The primary group is just a designated single group associated with a user, not an automatically updated membership set.
