Which of the following can a TA submit?

A Trusted Agent (TA) plays a crucial role in the management and oversight of Public Key Infrastructure (PKI) within the US Army. Among the various actions a TA can take, submitting a Suspension or Revocation request is particularly important. This ability allows the TA to manage the validity of certificates, which is essential for maintaining the integrity and security of the PKI environment.

The Suspension or Revocation request is a formal mechanism by which a TA can indicate that a user’s certificate should be suspended temporarily or revoked entirely. This may occur for a variety of reasons, such as the user's departure from the organization, loss of access credentials, or changes in access requirements. The timely submission of such requests is critical to prevent unauthorized access and ensure that the PKI remains a trusted system.

In contrast, while the other options may represent valid requests within an organization, they typically fall outside the specific responsibilities and authority assigned to a TA. Requests for user training, additional tokens, or system access typically involve different processes or personnel within the organization and do not directly pertain to the security management functions that TAs are authorized to perform. Thus, the ability of a TA to submit a Suspension or Revocation request is a defining aspect of their role in maintaining PKI
