Which of the following describes the outcome of a revoked certificate?

When a certificate is revoked, it indicates a complete cancellation of the holder's rights to practice or operate under that certification. This means that once the certificate is revoked, the individual is permanently barred from using that certification for professional purposes. The revocation is typically a serious consequence often resulting from violations of standards or regulations associated with the certification.

In contrast, other potential outcomes like remaining valid under certain conditions or being subject to future review imply that there is still some pathway to regaining certification, which does not apply when a certificate is irrevocably revoked. Additionally, the requirement to complete additional training would suggest a corrective measure rather than a disqualification from certification altogether. Thus, the outcome associated with a revoked certificate clearly leads to the permanent loss of that certification.
