Exam CMMC-CCP Topic 1 Question 156 Discussion

Step 1: Understand the "CA" Domain - Security Assessment
TheCA (Security Assessment)domain includes practices related to:
Planning security assessments,
Performing periodic reviews,
Managing plans of action and milestones (POA&Ms).
These practices derive fromNIST SP 800-171, specifically:
CA.2.157- Develop, document, and periodically update security plans,
CA.2.158- Periodically assess security controls,
CA.2.159- Develop and implement POA&Ms.
#Step 2: Review CMMC Levels
Level 1 (Foundational):
Implements only the17 practicesfromFAR 52.204-21
Doesnot include the CA domain
Level 2 (Advanced):
Implements110 practicesfromNIST SP 800-171, including CA.2.157-159
First levelwhereSecurity Assessment (CA)practices are required
Level 3:
Not yet finalized but intended to include selected controls fromNIST SP 800-172
#Why the Other Options Are Incorrect
A). Level 1
#No CA domain practices are present at Level 1.
C). Level 3 / D. Level 4
#These levels build on CA practices but do not represent thestarting point.
TheSecurity Assessment (CA)domain practices begin atCMMC Level 2, as part of the implementation ofNIST SP 800-171.
