Q1You are a CCA working with a client who is preparing for a CMMC assessment. The organization has requested your help in creating an information flow diagram of their document management system to ensure readiness. What would be the first step in constructing this information flow diagram? Module Major Inputs Major Outputs Document Creation Raw text, Templates Digital documents Document Storage Digital documents Archived documents Document Retrieval User requests Accessed documents Document Deletion Deletion requests Removed documents
✓ Correct answer: D. Identify how information moves through the document management system, highlighting major inputs and outputs for each module
Answer: Identify how information moves through the document management system, highlighting major inputs and outputs for each module The first step in constructing an information flow diagram for the document management system is to identify and document the major inputs and outputs associated with each module. This foundational step enables the development of a comprehensive diagram that visually represents the information flow within the system, which is essential for CMMC assessment readiness.
Q2During a CMMC Level 3 assessment, a CCA will evaluate whether the organization meets the requirement to Implement multi-factor authentication (MFA) for all network access to privileged accounts. Which assessment procedure would the CCA most likely use to evaluate this requirement?
✓ Correct answer: C. Examine system logs and configuration files that confirm the use of multiple authentication factors for privileged accounts
To evaluate the implementation of MFA, the primary assessment procedure for the CCA is to examine system logs and configuration files that confirm MFA use. While interviewing personnel or observing users may provide context, these methods do not conclusively determine MFA implementation. Examining logs and configuration files ensures the control is actively implemented.
Q3As a CCA performing a CMMC compliance assessment, you need to verify that an organization's training practices align with cybersecurity policies in practice AC.L2-3.1.2.4. Which type of document would be the most appropriate to examine for this purpose?
✓ Correct answer: A. Staff compliance acknowledgments
The correct answer is Staff compliance acknowledgments. To assess whether training practices are aligned with cybersecurity policies under practice AC.L2-3.1.2.4, the Certified CMMC Assessor would examine staff compliance acknowledgments. These records indicate that employees have read and understood the policies, supporting the alignment between training content and policy requirements. Other options, such as training completion records and policy dissemination records, do not confirm direct acknowledgment and understanding of specific policies.
Q4While assessing a financial services company for CMMC compliance, you note that they have an advanced monitoring system logging diverse transaction anomalies and access attempts. However, the company does not have a documented process for regularly reviewing its logging policies. Interviews with their cybersecurity team reveal that they revisit the system occasionally without a predefined schedule or criteria. What is the primary benefit of implementing CMMC guidelines for regular event log review in this context?
✓ Correct answer: C. It guarantees the logged events remain relevant and sufficient for detecting threats.
Regular review of logged events as per CMMC guidelines ensures that logging policies remain effective for the company's current and emerging threat landscape. Without scheduled reviews, certain relevant event types may be overlooked, thereby weakening the system's ability to detect threats promptly.
Q5You are evaluating a company's compliance with audit logging protection using FIPS-validated encryption to meet Level 2 requirements of the CMMC standards. What documentation cannot be provided as valid evidence of compliance?
✓ Correct answer: D. Network topology diagrams
Answer: Network topology diagrams To demonstrate FIPS validation for audit logging encryption, one must cite evidence like specifications of the encryption mechanisms, validation certificates, and encryption settings documentation. Network topology diagrams do not demonstrate adherence to FIPS encryption requirements.
Q6You are evaluating Zentech Corp, a company that operates a cloud services platform handling sensitive data for numerous clients. During your review, you discover that marketing employees were able to access protected client data files. The access logs show unusual activity from multiple accounts in the "Marketing_Team" group accessing data intended only for the "IT_Security" group. Which error likely led to this unauthorized access?
✓ Correct answer: B. Misconfigured role group policies
Misconfigured role group policies led to the marketing employees gaining access to data reserved for the IT security team. Such an error indicates improper separation between role permissions, allowing crossover of access rights that violate least privilege principles. Correctly categorizing and assigning permissions is crucial to preventing unauthorized data access.
Q7You are tasked to assess a private aerospace company looking to secure CMMC certification for their work related to satellite systems. The company handles sensitive communication technologies and has implemented significant measures to mitigate insider threats. During your assessment, you learn that the company tracks anomalies such as attempts to access restricted communication channels, sudden changes in financial status among personnel, and behavioral shifts indicating potential exploitation vulnerabilities. They conduct quarterly security awareness sessions and use biometric monitoring in high-security zones. Employees with access to highly sensitive channels receive intensive insider threat awareness training. After conducting interviews with the company's CIO, who confirms the full implementation of CMMC practice AT.L2-3.2.3-Insider Threat Awareness, how would you score their program for compliance?
✓ Correct answer: A. +1
The company has effectively implemented the required measures, meeting the CMMC practice standards, thus a score of +1 is warranted, indicating that the practice is MET.
Q8You are conducting a CMMC assessment for a contractor responsible for maintaining a critical supply chain network for the DoD. During the assessment of the Media Protection (MP) domain, you request a review of the contractor's access control documentation, focusing on the management of encryption and decryption keys. The contractor employs a Data Custodian role to manage these keys. However, during interviews, you discover that the Data Analysts and IT Support roles also have access to certain key management functions. When questioned about this practice, the contractor's security team explains that these roles need access for operational continuity and data processing efficiency. Based on this scenario, how would you assess the contractor's compliance with CMMC practice MP.L2-3.8.2-Key Management?
✓ Correct answer: C. Not Met - The contractor allows multiple roles access to key management functions, violating the restriction to a limited subset of defined privileged users.
Answer: Not Met - The contractor grants access to key management functions across various roles, contravening the CMMC requirement to restrict this access to a narrowly defined subset of privileged users. The contractor should limit key management access only to the Data Custodian to comply with CMMC practice MP.L2-3.8.2.
Q9In the realm of cloud-security, organizations increasingly rely on cloud-based systems for storing and processing sensitive data. To comply with CMMC standards when using these systems, a contractor must ensure that any identifiers used are robust, consistent, and facilitate tracking within the cloud environment. As a CMMC Assessor, you are tasked with evaluating an organization's cloud security practices, specifically concerned with identifier usage for accessing cloud services. What is the primary consideration for a contractor when selecting an identifier for these cloud-based systems?
✓ Correct answer: D. Choosing an identifier that ensures traceability and consistency for all users across the cloud environment.
The correct choice emphasizes traceability and consistency, which are key in ensuring secure and compliant access to cloud-based systems. The CMMC standards highlight the need for identifiers to be robust and uniform to track, manage, and control access across multiple users in a cloud environment.
Q10A small healthcare facility recently experienced a series of cybersecurity incidents related to unauthorized data access during system upgrade activities. The organization's IT team has been using unapproved software tools, leading to potential data breaches. As a certified CMMC assessor, you have been asked to provide a recommendation to help them meet CMMC practices, specifically regarding system maintenance control. What action should the facility take to comply with CMMC practice MA.L2-3.7.2?
✓ Correct answer: B. Develop and strictly enforce policies and procedures for reviewing, approving, and monitoring all maintenance activities and the tools used.
The correct action involves establishing and enforcing comprehensive policies and procedures to control and monitor maintenance processes. This helps ensure that all tools and techniques used are approved and do not expose the organization to unnecessary risk, thereby aligning with CMMC practice MA.L2-3.7.2 requirements.
