Cyber AB CMMC-CCA Online Questions & Answers

• Question 431:

  The assessment team has divided responsibilities to review portions of the OSC's scope, including the Host Unit, the specific enclave, and supporting teams such as a Managed Security Service Provider (MSSP). During evidence review, the team notices that MSSP personnel answered interview questions somewhat differently than OSC personnel.

  To clarify this inconsistency, the Lead Assessor decides to take all the following steps EXCEPT:

  A. Review the network diagrams.
  B. Review the agreement with the MSSP.
  C. Review the notes to determine what was different.
  D. Review interview questionnaire consistency.
  D. Review interview questionnaire consistency.

  ---

  Explanation

  Applicable Requirement (CMMC Assessment Process): The CMMC Assessment Process (CAP) requires assessors to collect, analyze, and reconcile evidence using triangulation (examine, interview, test) to confirm whether requirements are MET or NOT MET. When inconsistencies arise, the assessor must go back to objective evidence such as diagrams, contracts, and notes.

  Why Reviewing Network Diagrams Helps (supports A): Network diagrams provide authoritative evidence of scope, data flows, and system boundaries, which helps clarify whether the MSSP's services were accurately described.

  Why Reviewing MSSP Agreements Helps (supports B): Agreements (such as interconnection security agreements or service-level agreements) define shared responsibilities and confirm how the MSSP supports security controls. This evidence is critical to resolving inconsistent testimony.

  Why Reviewing Notes Helps (supports C): Notes from previous interviews allow the team to pinpoint where answers diverged. This is a valid method of evidence review and aligns with CAP guidance on documenting interviews.

  Why Interview Questionnaire Consistency is NOT the Correct Step (refutes D): The CAP emphasizes resolving inconsistencies through additional evidence, not by adjusting or re-checking the questionnaire itself. The consistency of the questionnaire is irrelevant - what matters is reconciling the evidence provided by both the OSC and MSSP. Thus, this is the action the Lead Assessor would NOT take.

  Assessment Guidance Extract (CAP):

  "When conflicting evidence is observed, the assessment team must review technical documentation, agreements, and notes to identify the root cause and determine whether additional clarification is required." "The interview instrument itself is not a tool for reconciling inconsistencies; rather, objective evidence must be used."

• Question 433:

  You are part of the Assessment Team assessing a small defense contractor. You learn that the contractor (ABC Manufacturing) outsources parts of its IT infrastructure and cybersecurity services to a reputable Managed Services Provider (MSP). During a CMMC assessment, the contractor's Assessment Official claims that several CMMC practices related to system security and monitoring are inherited from the MSP.

  Which of the following actions should the Lead Assessor take?

  A. Automatically accept the contractor's claim and score the inherited practices as `MET' without further evaluation.
  B. Recommend that the OSC implement the inherited practices internally, as inheriting from external providers is not allowed.
  C. Score the inherited practices as `NOT MET' and require ABC Manufacturing to implement them internally.
  D. Request evidence from the MSP to verify that their services meet the assessment objectives for the inherited practices and are applicable to ABC Manufacturing's in-scope assets.
  D. Request evidence from the MSP to verify that their services meet the assessment objectives for the inherited practices and are applicable to ABC Manufacturing's in-scope assets.

• Question 434:

  The OSC uses an on-premises ERP system that processes and stores CUI data. A Third-Party Maintenance (TPM) provider has remote access to the ERP system for troubleshooting and maintenance purposes. The OSC allows the TPM to access the system through a secure remote access tool with Multi-Factor Authentication (MFA).

  As a Lead Assessor, what challenges might you encounter when assessing the OSC's compliance with CMMC's practice AC.L2-3.1.12 - Control Remote Access?

  A. The use of a dedicated remote access tool simplifies the assessment of access controls
  B. You might still face challenges in obtaining evidence of how the TPM's remote access sessions are monitored and controlled to ensure remote access sessions are controlled and authorized
  C. CMMC requirements apply only to cloud-based systems, not on-premises deployments
  D. You may have difficulty verifying the effectiveness of the on-premises security measures
  B. You might still face challenges in obtaining evidence of how the TPM's remote access sessions are monitored and controlled to ensure remote access sessions are controlled and authorized

• Question 435:

  An aerospace company bids on a DoD contract that requires CMMC Level 2 compliance. The company has multiple divisions, but only the Manufacturing Division will work on the project. The Manufacturing Division has its own IT infrastructure and security policies, but it relies on thecompany's centralized IT department for some administrative tasks.

  Which unit will be assessed for CMMC Level 2 compliance?

  A. The Manufacturing Division
  B. The centralized IT department
  C. The Manufacturing Division and the centralized IT department
  D. The entire aerospace company
  A. The Manufacturing Division

• Question 436:

  After completing a CMMC assessment, the OSC should hash all the evidence artifacts in accordance with the CMMC Artifact Hashing Tool User Guide. However, you have just realized that this requirement was not fulfilled, and the OSC Assessment Official cannot be reached to confirm it was done. To avoid any issues, you quickly complete this step and later inform the OSC Assessment Official.

  Which CoPC principle have you just violated by hashing the evidence artifacts in place of the OSC?

  A. Professionalism
  B. Confidentiality
  C. Objectivity
  D. Information Integrity
  D. Information Integrity

• Question 437:

  You are conducting a CMMC assessment for a contractor that develops software applications for the DoD.

  During the assessment of the AU domain, you request to examine the contractor's audit and accountability policies, access control procedures, and system configuration documentation related to the management of audit logging functionality. Upon reviewing the documentation, the contractor has implemented a Role-Based Access Control (RBAC) model, where privileged users are assigned different roles based on their responsibilities. One of these roles is the "Audit Administrator" role, which is granted the necessary privileges to manage audit logging functionality across the contractor's systems. However, during interviews with the system administrators, you learn that besides the Audit Administrator role, several other privileged roles, such as the "System Administrator" and "Network Administrator" roles, can also manage audit logging functionality. When you inquire about the rationale behind granting multiple privileged roles access to audit management functions, the contractor's security team explains that this approach allows for better operational flexibility and ensures that different teams can perform audit logging tasks based on their areas of responsibility.

  Based on the information provided in the scenario, how would you assess the contractor's compliance with CMMC practice AU.L2- 3.3.9 - Audit Management?

  A. Partially Met - The contractor has limited audit management privileges to a subset of privileged users, but the roles may not be appropriately defined
  B. Met - The contractor has defined privileged user roles for audit management
  C. Not Applicable - The practice is not relevant to the contractor's environment
  D. Not Met - The contractor has granted audit management privileges to multiple privileged roles, which goes against the requirement to limit access to a subset of defined privileged users
  D. Not Met - The contractor has granted audit management privileges to multiple privileged roles, which goes against the requirement to limit access to a subset of defined privileged users

• Question 438:

  The team is assessing an OSC that uses the cloud for hosting its online services.

  Which of the following is NOT important for the assessor to consider?

  A. Devices connecting to the system are authorized.
  B. Processes acting on behalf of a user are authenticated.
  C. Users are authorized as a prerequisite to system access.
  D. FIPS encryption is authenticated as a prerequisite to system access.
  D. FIPS encryption is authenticated as a prerequisite to system access.

  ---

  Explanation

  Applicable Requirement: SC.L2-3.13.8 (Cryptographic protection of communications) and IA.L2-3.5. x (Identification and authentication).

  Why Option D is Correct: Encryption must be validated as FIPS 140-2/3 compliant but is never "authenticated as a prerequisite to access." Authentication applies to users, devices, and processes, not cryptographic modules themselves.

  Why Option A, B, C are Correct Considerations: Devices must be authorized before connecting.

  Processes acting on behalf of a user must be authenticated.

  Users must be authorized prior to access. These are all directly mapped to AC and IA domains.

• Question 439:

  An engineering company works on DoD contracts that involve handling CUI. They use hardcopy media such as printed paper, microfilms, and digital media, including flash drives, SSDs, DVDs, and internal and external hard drives. During a CMMC assessment, you discover the engineering company has defined procedures addressing media storage and access governed by an access control policy. All media containing CUI is marked and stored in biometrically locked cabinets. To store CUI on digital media, an authorized user must be identified using their biometrics or authenticated using an integrated MFA solution. To access non-digital media, the user must be on a defined list of authorized personnel and sign three forms. You also learn that the contractor maintains a comprehensive inventory of all CUI media. The scenario describes a multi-factor authentication (MFA) solution being used to access digital media containing CUI. However, the access control procedures for non-digital media require authorized personnel to sign three separate forms.

  While both methods aim to verify user identity, which of the following is the MOST significant security concern associated with the reliance on a paper-based form process?

  A. The paper forms cannot be easily integrated with other security systems
  B. It can be time-consuming to complete the forms for frequent access
  C. It requires users to memorize more information for access
  D. The forms are susceptible to forgery, resulting in unauthorized access
  D. The forms are susceptible to forgery, resulting in unauthorized access
