Which of the following is NOT an appropriate use of your Common Access Card (CAC)?

The correct choice identifies an inappropriate use of your Common Access Card (CAC) because exchanging it for a visitor pass in another building can lead to a misuse of secure identification protocols. The CAC is specifically designed to be a secure form of identification that provides access to certain systems and facilities for authorized personnel. When you exchange your CAC for a visitor pass, it can compromise the security requirements intended for those who need limited or temporary access.

Using the CAC in a manner not aligned with its intended purpose can also confuse personnel protocols and result in unauthorized access to secure areas or systems. The other options illustrate appropriate practices involving the CAC, such as reporting its loss, using it on secure systems, and storing it in a protective sleeve, which help maintain security and integrity.
