The primary purpose of Microsoft Entra Privileged Identity Management (PIM) is to enforce the principle of least privilege. It achieves this by moving away from permanent ("standing") administrative access. Instead, PIM enables organizations to provide just-in-time (JIT) privileged access, where users must request and justify elevation into a role. This access is time-bound, meaning it automatically expires after a set period. This process minimizes the window of opportunity for attackers to compromise highly privileged accounts and reduces the overall security risk associated with standing admin roles.

A. Storing passwords in a separate vault is a function of a password manager or vaulting solution, not the primary purpose of PIM.

B. Automatically backing up configuration settings is a function of backup and recovery tools, which is unrelated to identity and access management.

D. Encrypting network traffic is a function of protocols like TLS or solutions like VPNs, not a role of Privileged Identity Management.
