Question 210
A Windows device appears twice in Entra after it was rebuilt and renamed, confusing asset ownership and conditional access reports. How should the endpoint team implement the requested control?
Explanation
Correct Answer
This is the most targeted action: Correlate device IDs and lifecycle state before removing a verified stale registration. The technical distinction is that display-name similarity is insufficient to distinguish an active device from an orphan. Confirm the change by checking: One active device identity remains after the stale entry is retired and no active access breaks.
Incorrect Answers
This action is appropriate for a different case: A device loses its Entra primary refresh token after a password reset and cloud application single sign-on stops functioning. There, the targeted fix is 'Inspect Entra sign-in/device diagnostics and refresh device authentication through supported steps.' because token and device identity failures should be isolated before reimaging. The current scenario instead requires 'Correlate device IDs and lifecycle state before removing a verified stale registration.' and verification that one active device identity remains after the stale entry is retired and no active access breaks.
This action is appropriate for a different case: A shared meeting-room Windows device should not be associated with an individual employee for sign-in identity and assignment. There, the targeted fix is 'Plan an organization-owned shared device enrollment and appropriate Entra device identity.' because shared-use devices should not inherit an arbitrary employee's personal management scope. The current scenario instead requires 'Correlate device IDs and lifecycle state before removing a verified stale registration.' and verification that one active device identity remains after the stale entry is retired and no active access breaks.
This action is appropriate for a different case: A technician attempts to Entra join company devices using an account that is not permitted to join additional devices. There, the targeted fix is 'Review Entra device-join permissions and per-user device limits before repeating enrollment.' because authentication alone does not override tenant device join restrictions. The current scenario instead requires 'Correlate device IDs and lifecycle state before removing a verified stale registration.' and verification that one active device identity remains after the stale entry is retired and no active access breaks.
