Which of the following responsibilities are associated with the ETA role?

The responsibilities associated with the Elevated Trusted Agent (ETA) role encompass both verifying a subscriber's identity and resetting their PIN.

Verifying a subscriber's identity is a critical function of the ETA, as it ensures that the individual requesting access to the Public Key Infrastructure (PKI) services is indeed who they claim to be. This step is fundamental in maintaining security and trust within the PKI framework, as it prevents unauthorized access to sensitive data and resources.

Additionally, the ability to reset a subscriber's PIN is another essential task of the ETA. Subscribers may forget their PINs or may need to reset them for security reasons. The ETA plays a pivotal role in managing this process, allowing for the necessary support to maintain users’ access while ensuring the integrity and security of the PKI system.

Together, these responsibilities enable ETAs to effectively support subscribers and uphold the PKI's integrity, making the combined answer of both confirming the subscriber's identity and resetting PINs the most accurate representation of the ETA role's responsibilities.
