Cyber AB CMMC-CCA Dumps Questions Answers

CMMC allows for compensating controls when technical limitations prevent direct application of MFA on certain systems. In such cases, a valid second factor can be a strong physical access control mechanism.

Extract from IA.L2-3.5.3 (Use of multifactor authentication):

“Multifactor authentication can be implemented by combining something you know (e.g., password) with something you have (e.g., physical badge), or something you are (e.g., biometric). Physical access controls, such as badge-protected facilities, can serve as a compensating factor when direct MFA on the system is not technically possible.”

Therefore, badge access to the mission system room serves as a sufficient second factor.

Logical separation refers to the use of technical and access control mechanisms (e.g., role-based access, IAM tools, VLANs) to enforce boundaries between different users, roles, or networks. In contrast, physical separation relies on distinct hardware or physical barriers. Role-based access control within an IAM solution is a textbook example of logical separation, and it is specifically called out in the CMMC/NIST context.

Exact extracts:

“Logical separation may be achieved through the use of virtualization, encryption, or access control mechanisms such as role-based access controls.”

“Assessment Objectives … Determine if: • separation of users and information types is enforced by physical or logical means.”

“Logical separation is implemented using technical solutions such as access control lists, firewalls configured by policy, or identity and access management solutions.”

Why the other options are incorrect:

A (Data loss alerting): This is monitoring, not separation.

B (Badge access): This is a physical access control, not logical separation.

D (Proxy-configured firewall): This is boundary protection/traffic control; depending on setup it may be physical or logical, but the scenario points to role-based IAM as the logical example.

The Lead Assessor is responsible for managing the assessment team and planning the assessment, including defining the methods, techniques, and responsibilities for collecting, managing, and reviewing evidence. Team members execute assigned tasks, but the Lead Assessor provides direction and oversight.

“The assessment team members carry out activities as directed by the Lead Assessor.”

“The C3PAO Quality Oversight and CMMC Quality Assurance are post-assessment quality functions, not evidence planning functions.”

Why other options are not correct:

B: Team members execute tasks but do not define methods and responsibilities.

C: Quality Oversight Managers review assessments after completion, not during planning.

D: CMMC Quality Assurance Professionals conduct QA on assessments, not evidence planning.
