Public Key Infrastructure (PKI) Practice Exam

The correct answer indicates that a subscriber's SIPRNet email address should not be included on the DD Form 2842. This document is primarily used to grant access to specific secure communications and information systems, and it is crucial to maintain the confidentiality and integrity of classified communications. Including external or system-specific email addresses could potentially lead to unauthorized access or breaches of security protocols.

In a PKI context, security best practices emphasize limiting exposure to sensitive information within official documentation. By excluding the SIPRNet email address, the form remains focused on necessary identification and verification without compromising network security.
