Cyber AB CMMC-CCA Online Questions & Answers

• Question 441:

  An OSC has a testing laboratory. The lab has several pieces of equipment, including a workstation that is used to analyze test information collected from the test equipment. All equipment is on the same VLAN that is part of the certification assessment. The OSC claims that the workstation is part of the test equipment (Specialized Asset) and only needs to be addressed under risk-based security policies.

  However, the OSC states that the data analysis output is CUI.

  What is the assessor's BEST response?

  A. Disagree with the OSC and include the workstation in the full assessment.
  B. Disagree with the OSC and score practice CA.L2-3.12.4: System Security Plan as NOT MET.
  C. Agree with the OSC but perform a limited check of the system, not increasing the assessment cost or duration.
  D. Agree with the OSC and determine if it is managed using the contractor's risk-based information security procedures and practices.
  A. Disagree with the OSC and include the workstation in the full assessment.

  Explanation

  If an asset processes or generates CUI, it is a CUI Asset by definition, regardless of whether it is also part of a test lab or claimed as a Specialized Asset. Specialized Asset handling applies only when the asset does not process, store, or transmit CUI. Since the workstation outputs CUI, it must be assessed fully against CMMC practices.

  Exact extracts:

  "CUI Assets are those that process, store, or transmit CUI."

  "Specialized Assets... do not process, store, or transmit CUI."

  "If a Specialized Asset processes CUI, it must be categorized as a CUI Asset and is assessed against all applicable practices."

  Why the other options are incorrect:

  Option B: The issue is not with the SSP practice; it is with misclassification of an asset.

  Option C/D: Risk-based treatment applies only to Specialized Assets without CUI, which is not the case here.

• Question 442:

  An OSC is preparing for assessment.

  Which item of evidence would show the OSC's efforts to restrict physical access within the OSC's environment?

  A. VPN configuration
  B. Switch configuration files
  C. Network architecture drawings
  D. Documented OSC procedures
  D. Documented OSC procedures

  ---

  Explanation

  Applicable Requirement: PE.L2-3.10.1 -"Limit physical access to organizational information systems, equipment, and the respective operating environments to authorized individuals."

  Why Option D is Correct: Documented procedures describing physical access restrictions (badge policies, visitor management, locked server rooms, guard post orders) serve as primary evidence that access is managed and enforced.

  Assessors can then corroborate via interviews and observation.

  Why Other Options Are Insufficient:

  Option A (VPN configuration): Relates to remote logical access, not physical security.

  Option B (Switch configs): Technical network controls, not physical access.

  Option C (Architecture drawings): Show logical/system design, not physical entry restrictions.

• Question 443:

  You are a Lead Assessor on a CMMC Assessment Team preparing for an upcoming assessment. You have received the final assessment scope and supporting documentation from the OSC.

  What should you do next?

  A. Determine the feasibility of conducting the assessment.
  B. Immediately begin the assessment based on the provided scope and documentation.
  C. Submit the assessment scope and documentation to the C3PAO for approval.
  D. Verify that the assessment team members are familiar with the assessment scope, method, plan, and tools.
  A. Determine the feasibility of conducting the assessment.

• Question 444:

  As the Lead Assessor for an OSC, John admires their advanced security solutions during the assessment.

  However, his admiration distracts him from the assessment's focus. Instead, he engages in conversation about the OSC's robust security, becoming swayed by their capabilities. Consequently, John becomes hesitant to identify deficiencies or noncompliances, displaying a positive bias toward the OSC.

  What is the impact of this positive bias on the CMMC assessment of the OSC?

  A. It is not a concern in CMMC assessments
  B. It may lead to a more thorough and rigorous evaluation of the OSC
  C. It has no effect on the assessment process and outcomes
  D. It can result in a more lenient and inaccurate assessment of the OSC
  D. It can result in a more lenient and inaccurate assessment of the OSC

• Question 445:

  You are a CCA working with an OSC that outsources some of its IT operations to a third-party service provider. The service provider has access to the OSC's networks and systems that handle FCI and CUI.

  During the scoping process, you need to determine if the OSC should flow down CMMC requirements to this third-party service provider.

  In this scenario, when should the OSCflow down CMMC requirements to the third-party service provider?

  A. The OSC should only flow down CMMC requirements if explicitly stated in the contract with the third-party service provider.
  B. The OSC should flow down CMMC requirements to the third-party service provider since they have access to the FCI/CUI environment and can directly or indirectly influence it.
  C. The OSC should never flow down CMMC requirements to third-party service providers.
  D. The OSC should flow down CMMC requirements to the third-party service provider only if they handle CUI but not FCI.
  B. The OSC should flow down CMMC requirements to the third-party service provider since they have access to the FCI/CUI environment and can directly or indirectly influence it.

• Question 446:

  An OSC is undergoing a CMMC Level 2 assessment, and the C3PAO Assessment Team has identified several practices that the organization has not yet fully implemented. During the assessment, the CCA notes significant progress by the OSC towards implementing control MP.L2-3.8.4 - Media Markings, but acknowledges that not all required steps have been completed. The CCA explains to the OSC that this partially implemented practice will need to be tracked in the Limited Practice Deficiency Correction Program.

  How should CMMC practices tracked under the Limited Practice Deficiency Correction Program be scored?

  A. Not Met
  B. Partially Met
  C. Not Applicable
  D. Met
  A. Not Met

• Question 447:

  A CMMC Level 2 certified DoD contractor plans to use a Cloud Service Provider (CSP) to support data storage and application hosting for their business operations. The contractor is aware of the CMMC requirements and wants to ensure compliance before engaging with the cloud service provider. After discussing this with them, you learn that most of the hosted applications aren't used for any activities related to the DoD contract. However, the stored data may contain Controlled Unclassified Information (CUI).

  What requirement must the CSP have met before the DoD contractor can hire them?

  A. FedRAMP High ATO
  B. Employment of personnel compliant with DoD 8570 requirements
  C. CMMC Level 1 Certification
  D. Security requirements equivalent to the FedRAMP Moderate baseline or CMMC Level 2 Certification
  D. Security requirements equivalent to the FedRAMP Moderate baseline or CMMC Level 2 Certification

• Question 448:

  A CCA is assessing the implementation of SC.L2-3.13.7: Split Tunneling control via the examine method.

  Which scenario MUST be correct to determine if the practice is MET?

  A. The CCA tested that VPN mechanisms disallow split tunneling.
  B. The CCA corroborated that split tunneling is disabled with a system or network administrator.
  C. The CCA determined that split tunneling mechanisms have been disabled based on the system hardware, software, and architecture.
  D. The CCA evaluated that split tunneling mechanisms have been disabled based on the mechanisms supporting or restricting non-remote connections.
  C. The CCA determined that split tunneling mechanisms have been disabled based on the system hardware, software, and architecture.

  ---

  Explanation

  Applicable Requirement: SC.L2-3.13.7 -"Prevent split tunneling for remote devices connecting to organizational systems."

  Assessment MethoOption D: "Examine" requires direct review of system hardware, software, and architecture to verify split tunneling is disabled.

  Why Option C is Correct: This aligns with the NIST SP 800-171A assessment objective, which specifies verifying that mechanisms enforcing the prevention of split tunneling are implemented at the system level.

  Why Other Options Are Insufficient:

  Option A: Describes "test" method, not "examine."

  Option B: Describes "interview" method, not "examine."

  Option D: Too general and vague; does not align to evidence required under "examine."

• Question 449:

  Examining an OSC password policy, you learn that a password should have a minimum of 15 characters.

  It also should have 3 uppercase, 2 special characters, and other alphanumeric characters. Passwords have to be changed every 45 days and cannot be easily tied to the account owner. Passwords cannot be reused until 30 cycles are complete. The OSC's systems send a temporary password to the user's email or authentication app, which is one of the events described in their password usage policy. However, a recent penetration test report shows that the generated temporary passwords did not have sufficient entropy, and an attacker may guess a temporary password through brute force attacks.

  Which CMMC practice has the contractor successfully implemented?

  A. IA.L2-3.5.9 -Temporary Passwords
  B. IA.L2-3.5.7 -Password Complexity and IA.L2-3.5.8 -Password Reuse
  C. IA.L2-3.5.3 -Multifactor Authentication
  D. IA.L2-3.5.6 -Identifier Handling
  B. IA.L2-3.5.7 -Password Complexity and IA.L2-3.5.8 -Password Reuse

• Question 450:

  A CCA is assessing an OSC that uses a complex multi-cloud architecture with resources distributed across multiple Cloud Service Providers (CSPs). During the evaluation, the CCA encounters challenges in verifying the authorization methods used for external connections to the various cloud resources (AC.L1- 3.1.20). Additionally, the assessor finds limited documentation of the cryptographic mechanisms implemented to protect the confidentiality of remote access sessions (AC.L2-3.1.13) to cloud-based data.

  While the OSC has network monitoring tools in place, the sheer volume of data makes it difficult to identify and track specific remote access activities.

  What challenges might the CCA face while assessing the OSC's cloud and hybrid environment for compliance with CMMC remote access requirements?

  A. Outdated network infrastructure and insufficient bandwidth
  B. Excessive focus on physical security measures while neglecting logical controls
  C. Difficulty verifying access control policies and lack of qualified personnel
  D. Difficulty in verifying external connection authorization methods and limited evidence of cryptographic mechanisms for remote access
  D. Difficulty in verifying external connection authorization methods and limited evidence of cryptographic mechanisms for remote access
