For a scoping a CMMC Level 1 Self-Assessment, which asset types are assessed against CMMC...

The correct answer is D because CMMC Level 1 scoping is driven by whether an asset processes, stores, or transmits Federal Contract Information (FCI). The Level 1 Scoping Guide states that in-scope assets for a Level 1 self-assessment are all assets that process, store, or transmit FCI, and that these assets are part of the CMMC Assessment Scope and assessed against all Level 1 requirements. The guide also defines transmitting as FCI being transferred from one asset to another through physical or digital transport methods. The other options are attractive but incorrect because IoT, Industrial Internet of Things, Restricted Information Systems, and test equipment are treated as Specialized Assets when they can process, store, or transmit FCI but cannot be fully secured. Specialized Assets are documented and managed but are not assessed against CMMC Level 1 requirements in the same way as ordinary in-scope FCI assets. Therefore, the best answer is the general rule: any non-specialized asset transmitting FCI is assessed against CMMC Level 1 practices.
