評価チームは、OSCの要請に基づき、レベル2の評価を実施しています。チームは、提供された証拠に基づいて診療行為の採点を開始しました。診療行為がMET(基準を満たしている)と評価されるかどうかを判断するために、評価チームに最低限求められることは何ですか?
正解: D
この質問は、CMMC評価チームがレベル2評価において、ある診療所をMETと評価するために必要な最低限の証拠要件に関するものです。
The CMMC Level 2 assessment must align withNIST SP 800-171and follow the procedures outlined in theCMMC Assessment Process (CAP) Guide v1.0, particularly aroundevidence collection and scoring methodology.
#Step 1: Refer to the CMMC Assessment Process (CAP) Guide v1.0
CAP v1.0 - Section 3.5.4: Evaluate Evidence and Score Practices
"To assign a MET determination, the Assessment Team must collect and corroborate at least two types of objective evidence: either through examination of artifacts, interviews (affirmation), or testing (demonstration)." This meansat least two typesof the following evidence are required:
Examine(documentation/artifacts),
Interview(affirmation from personnel),
Test(demonstration of implementation).
#Step 2: Clarify the Official Minimum Standard for a Practice to be Scored MET The CAP explicitly states:
"A practice can only be scored MET when a minimum oftwo types of evidencefrom the E-I-T (Examine, Interview, Test) triad are successfully collected and evaluated." Theevidence types must come from two different categories, for example:
An artifact(Examine)+ an interview affirmation(Interview),
A demonstration(Test)+ an interview(Interview),
Etc.
This cross-validation ensures that the control isimplemented, documented, and understoodby personnel - a core principle in assessing effective cybersecurity implementation.
#Why the Other Options Are Incorrect
A). All three types of evidence are documented for every control
#Incorrect:While collecting all three types (E-I-T) strengthens the assessment, theminimum requirementis onlytwo. Collecting all three isnot requiredfor a practice to be scoredMET.
B). Examine and accept evidence from one of the three evidence types
#Incorrect:This fails to meet theminimum two-evidence-type requirementset by the CAP. Single-source evidence is not sufficient to score a practice as MET.
C). Complete one of the following; examine two artifacts, observe one demonstration, or receive one affirmation
#Incorrect:Even if two artifacts are examined,this is still only one type of evidence(Examine). The CAP requires twotypes- not two instances of the same type.
#Why D is Correct
D). Complete two of the following: examine one artifact, either observe a satisfactory demonstration of one control or receive one affirmation from the OSC personnel.
#This directly reflects theCAP's requirement for collecting two different types of objective evidenceto determine a practice is MET.
BLUF (Bottom Line Up Front):
To score a CMMC Level 2 practice asMET, the Assessment Team must collecta minimum of two distinct types of evidence- from theExamine, Interview, Test (E-I-T)categories. This requirement is clearly stated in the CMMC Assessment Process (CAP) v1.0.
