Practice question 313 of 498 · easy

Which identity design most directly supports revoking one compromised IoT device without replacing every fleet credential?

Choose the single best answer.

  1. A.Distinct device identities and scoped credentials
  2. B.Anonymous ingestion for every device
  3. C.One shared hub-owner secret in every device
  4. D.One administrator account reused by all devices
Show the answer and explanation

✓ Correct answer

  • Distinct device identities and scoped credentials

Distinct identities permit targeted revocation. A shared hub-owner secret grants excessive service authority and creates fleet-wide exposure. Anonymous ingestion cannot reliably identify a device. A shared administrator account prevents proper per-device isolation.
