What type of group should a System Administrator create to limit a security role to specific users?

Creating a static group is the appropriate choice for limiting a security role to specific users because static groups allow administrators to manually select and control the members within the group. This means that only the designated users who should have a particular security role can be added, ensuring tight control over who has access to certain functionalities or data.

Static groups are particularly useful when the membership does not change frequently, or when precise control over group membership is of paramount importance. By using a static group, the System Administrator can refine access based on specific organizational needs or security requirements.

Dynamic groups, on the other hand, automatically update their membership based on predefined criteria, which may not always align with the need for strict user access control. Combination groups blend static and dynamic elements, leading to more complexity in managing user roles. Conditional groups introduce additional conditions for membership, which might complicate direct administration.

Therefore, for straightforward and controlled access management focused on specific users, a static group stands out as the most effective option.
