What distinguishes a dynamic distribution group from a regular distribution group?

• A. Dynamic distribution group is based on a set of filters or conditions
• B. Dynamic distribution group is static; regular groups are dynamic
• C. Dynamic groups are used for security permissions; regular for email
• D. Dynamic groups are cloud-based; regular are on-prem

Answer: (A)

The key idea is how membership is determined. A dynamic distribution group builds its recipient list by applying a set of filters or conditions to user attributes (like department, location, title, etc.) at the moment an email is sent. This means who receives the message can automatically change as people’s attributes change, without you editing the group itself. In contrast, a regular distribution group has a fixed membership list that you explicitly manage—adding or removing members manually, and changes to a user’s attributes don’t automatically alter who is included.

So the best choice is that a dynamic distribution group is based on filters or conditions, while the regular group uses a static, manually managed membership. The other options aren’t correct because dynamic groups aren’t about security permissions, aren’t defined by cloud versus on-prem, and the core distinction isn’t about static versus dynamic in the opposite sense.
