When you assign users to a group in AppDynamics, you can manage their permissions and access levels more easily. A group is a collection of users who share the same roles and privileges. A role is a set of permissions that define what actions a user can perform on the Controller UI or the Events Service.
According to the System Configuration Guide for Cisco Unified Communications Manager - User Management, the following statement is true about assigning users to a group:
When you add a role to a group, every user in the group is assigned that role: This means that the users in the group inherit the permissions of the role that you add to the group. For example, if you add the Administrator role to a group, then all the users in that group can perform administrative tasks on the Controller UI or the Events Service.
The other statements are false because:
When you assign a user to a group, they can only have the roles assigned to that group: This is not true because a user can belong to multiple groups and have multiple roles. For example, a user can be in both the Administrator and the Operator groups and have the permissions of both roles.
You can list all users in a group that are logged into AppDynamics: This is not true because there is no such feature in AppDynamics that allows you to see thelogin status of the users in a group. You can only see the list of users and groups in the User Management page of the Controller UI or the Events Service.
When the user logs in they can log in with the group credentials: This is not true because a user cannot log in with the group credentials. A user can only log in with their own username and password. The group credentials are not used for authentication, but for authorization.
Therefore, D (When you add a role to a group, every user in the group is assigned that role) is the correct answer. References:
