On a Pure Storage FlashArray, Role-Based Access Control (RBAC) allows administrators to integrate with Directory Services (like Active Directory or OpenLDAP) to control user access. Purity uses a specific hierarchy for its administrative roles, which from highest to lowest privilege are: Array Admin, Storage Admin, Ops Admin, and Read Only.
When a user logs in and is found to be a member of multiple Active Directory or LDAP groups that are mapped to different roles on the FlashArray, Purity's behavior is designed to grant the user the highest level of permissions among those conflicting group mappings. Because the Array Admin role is higher in the hierarchy than the Storage Admin role, the user will successfully log in and be granted full Array Admin permissions.
Here is why the other options are incorrect:
Inability to login (A): Purity handles overlapping group memberships gracefully by defaulting to the highest privilege. It does not lock the user out or cause a login failure.
Storage Admin permissions (B): Because the system grants the highest available mapped privilege, the user will not be restricted to the lower-tier Storage Admin role when they also possess group membership for the Array Admin role.
