CMMC-CCP Cyber AB Exam Lab Questions

The CAP makes clear that evidence collected during the assessment is evaluated for both adequacy (does the evidence align with the requirement) and sufficiency (is there enough evidence to make a confident determination).

Supporting Extracts from Official Content:

CAP v2.0, Evidence Collection Guidance: “Evidence must be evaluated for adequacy… and for sufficiency, to ensure enough information is available to support the assessor’s determination.”

Why Option A is Correct:

Evidence is assessed based on two qualities only: adequacy and sufficiency.

“Thoroughness” and “appropriateness” are not official CAP terms for evidence evaluation.

References (Official CMMC v2.0 Content):

CMMC Assessment Process (CAP) v2.0, Evidence Evaluation section.

===========

Theprimary goal of CMMC assessment proceduresis to determine whether anOrganization Seeking Certification (OSC)complies with the cybersecurity controls required for its certification level. Themost common purpose of assessment procedures is to obtain evidencethat verifies an organization has properly implemented security practices.

Why "A. Obtain Evidence" is Correct?

CMMC Assessments Require Evidence Collection

TheCMMC Assessment Process (CAP) Guideoutlines that assessors must use three methods to verify compliance:

Examine– Reviewing documentation, policies, and system configurations.

Interview– Speaking with personnel to confirm understanding and execution.

Test– Validating controls through operational or technical tests.

All these methods involve obtaining evidenceto support whether a security requirement has been met.

Alignment with NIST SP 800-171A

CMMC Level 2 assessments follow NIST SP 800-171A, which is designed for evidence-based verification.

Assessors rely on documented artifacts, system logs, configurations, and personnel testimony as evidence of compliance.

Why Other Answers Are Incorrect?

B. Define level of effort (Incorrect)

Thelevel of effortrefers to the time and resources needed for an assessment, but this is aplanningactivity, not the primary goal of an assessment.

C. Determine information flow (Incorrect)

While understandinginformation flowis important for security controls likedata protection and access control, themain purpose of an assessment is to gather evidence—not to determine information flow itself.

D. Determine value of hardware and software (Incorrect)

Asset valuation may be part of an organization’s risk management process, but CMMC assessmentsdo not focus on determining hardware or software value.

Conclusion

The correct answer isA. Obtain evidence, as theCMMC assessment process is evidence-drivento verify compliance with security controls.

How Many Practices Are Included in CMMC Level 2?

CMMC Level 2is designed to alignfullywithNIST SP 800-171, which consists of110 security controls (practices).

This meansall 110 practicesfrom NIST SP 800-171 are required for aCMMC Level 2 certification.

Breakdown of Practices in CMMC 2.0

CMMC Level

Number of Practices

Level 1

17 practices(Basic Cyber Hygiene)

Level 2

110 practices(Aligned with NIST SP 800-171)

Level 3

Not yet finalized but expected to exceed 110

Since CMMC Level 2 mandatesall 110 NIST SP 800-171 practices, the correct answer isC. 110 practices.

Why the Other Answers Are Incorrect

A. 17 practices

❌Incorrect.17 practicesapply only toCMMC Level 1, not Level 2.

B. 72 practices

❌Incorrect. There is no CMMC level with72 practices.

D. 180 practices

❌Incorrect. CMMC Level 2only requires 110 practices, not 180.

CMMC Official References

CMMC 2.0 Model– Confirms thatLevel 2 includes 110 practicesaligned withNIST SP 800-171.

NIST SP 800-171 Rev. 2– Outlines the110 security controlsrequired for handlingControlled Unclassified Information (CUI).

Thus,option C (110 practices) is the correct answer, as per official CMMC guidance.
