What software is required for the TA to reset SIPRNet token PINs?

The correct choice is Token Management Software, which is specifically designed to handle tasks related to token management, including the resetting of PINs for tokens used in secure environments like SIPRNet. This type of software provides system administrators with the tools needed to manage digital certificates, token registration, and the secure handling of authentication processes, essential for maintaining the integrity and security of sensitive information systems.

While other options may seem relevant, they lack the direct functionality associated with token management. Administrative Access Software typically focuses on broader administrative tasks but does not specifically address token management. CIW Software is often associated with the Certified Internet Webmaster program, which does not pertain to cryptographic tokens or SIPRNet operations. Secure Access Software might involve network security measures but does not explicitly provide the PIN reset functionalities necessary for token operations. Thus, Token Management Software is the most appropriate answer for managing SIPRNet token PINs.
