The CMMC Scoping Guidance allows assets to be classified as Out-of-Scope if:

They are physically/logically isolated, and

They cannot process, store, or transmit CUI.

Extract:

“Out-of-Scope assets are those that cannot process, store, or transmit CUI and are physically or logically separated from CUI assets.”

The VESDA system only monitors environmental conditions and does not interact with CUI. Its segregation supports an out-of-scope classification.

Applicable Requirement (CAP – Scoping and Evidence Validation): When inconsistencies arise about the environment, assessors are required to examine objective artifacts that define boundaries, such as network diagrams and system architecture documentation.

Why A is Correct: Network diagrams objectively show whether systems are hosted on-premises or involve ESPs (cloud, MSSPs, hosting providers). Reviewing them avoids ambiguity from inconsistent verbal descriptions.

Why Other Options Are Insufficient:

B: Interviewing another OSC representative may add to confusion rather than resolve it.

C: Interconnection agreements confirm ESP relationships but do not resolve whether the OSC has on-prem or hybrid environments.

D: Contacting ESPs directly is not part of the assessment process; OSC must provide evidence.

===========

The Physical Protection (PE) practices require that visitors to facilities where CUI is processed must be escorted at all times by an authorized individual. Familiarity or long-term knowledge of the visitor does not remove the requirement.

Extract from PE.L2-3.10.3:

“Escort visitors and monitor visitor activity to ensure they do not access areas or information for which they are not authorized.”

Thus, the correct action is for the contact person (the engineer’s point of contact) to escort the engineer during the entire maintenance activity.

Applicable Requirement (CMMC Scoping Guidance – Specialized Assets): Specialized Assets (e.g., OT, IoT, GFE, test equipment) are not exempt from CMMC practices. OSCs must provide:

Documented identification in SSP/inventory,

Justification of specialized handling,

Evidence that risk-based security measures are implemented.

Why D is Correct: Assessors must see evidence that isolation is actually implemented (not just planned), plus supporting artifacts showing how remaining applicable practices are addressed (monitoring, inventory, access, etc.). Planned measures alone are insufficient.

Why Other Options Are Insufficient:

A: Installation/config builds do not show operational isolation.

B: Scoping statements alone do not demonstrate implementation.

C: SSP language is descriptive but must be supported by implementation evidence.

MP.L2-3.8.4 requires that CUI markings follow the media, meaning when electronic documents are printed, the original markings must carry over to the hard copy. Distribution lists or colored stamps are not specifically required.

Extract:

“Mark media containing CUI with the CUI designation indicators as required. When converting CUI from one medium to another, the original markings must be retained.”

Thus, the assessor should expect to see the original markings carried onto the printouts.

AC.L2-3.1.21 requires that the use of portable storage devices be restricted and explicitly authorized. The described process covers labeling and limiting use but does not include documented management authorization.

Extract:

“Restrict the use of portable storage devices on external systems. Authorization for use must be formally documented and approved by management.”

Thus, the missing element is recorded management authorization.

Practice AC.L2-3.1.3 requires that users are presented with privacy and security notices (system use notifications) at the point of system log-in to ensure that they are aware of authorized usage and monitoring.

Extract:

“Display privacy and security notices (system use notifications) before granting system access.”

Posters, alerts, or general awareness messages do not satisfy this practice because they are not tied directly to system access.

The Escort Visitors practice falls under Physical and Environmental Protection (PE.L2-3.10.3), which requires organizations to escort visitors and monitor visitor activity. To validate this, the assessor should interview personnel responsible for physical access control (security guards, facility access managers) and information security (to confirm integration with CUI protection requirements).

Exact Extracts:

PE.L2-3.10.3: “Escort visitors and monitor visitor activity.”

Assessment Guide: “Interview personnel responsible for physical access control and security monitoring to confirm escort and visitor activity tracking.”

Assessment Objectives: Require evidence of visitor escorts, visitor logs, and monitoring practices.

Why the other options are not correct:

A (Repair/maintenance): Not responsible for escort procedures.

B (Local access control only): Missing the information security link, which ensures visitors cannot access CUI assets.

D (IT management): IT is not responsible for escorting visitors in physical spaces.

The CMMC Assessment Process (CAP), Phase 2 – Conduct the Assessment defines the subphases for generating final recommended results. The steps are:

Determine final practice MET/NOT MET/NA results

Create, finalize, and record recommended final findings

Resolve assessment findings disputes

Extract:

“The assessment team determines the final practice status, records recommended findings, and resolves disputes with the OSC prior to finalizing recommended results.”

The CMMC Scoping Guidance defines Specialized Assets (e.g., OT, IoT, test equipment, manufacturing machines) that may process CUI but do not always meet traditional IT security requirements. These assets are still within scope and must be documented and assessed as Specialized Assets.

Extract:

“Specialized Assets are defined as operational technology, IoT, test equipment, and similar devices that may process CUI but cannot be secured in the same manner as standard assets. They remain in-scope for the assessment.”

Thus, waterjet machines are Specialized Assets in scope.
