NEW QUESTION # 85
As a Lead Assessor working with an OSC in preparation for an upcoming assessment, you request they appoint an Assessment Official. This is the individual you will collaborate with and who has the OSC's decision-making authority regarding the CMMC assessment. The OSC Assessment Official will lead and manage the OSC's engagement in the assessment. As the Lead Assessor, you expect the OSC Assessment Official to have the following responsibilities, EXCEPT?
- A. Identify assessment funding and authorize payment.
- B. Approve the assessment plan and review assessment results with the Lead Assessor.
- C. Sign off on the assessment scope and boundaries.
- D. Handle facility access and daily visitor escort.
Answer: D
Explanation:
Comprehensive and Detailed Explanation:
The CMMC Assessment Process (CAP) defines the OSC Assessment Official as the senior individual with decision-making authority, responsible for high-level oversight (e.g., funding, scope approval, plan review).
Facility access and visitor escort duties are operational tasks typically assigned to a Point of Contact (PoC) or security staff, not the Assessment Official. Options A, B, and C align with the CAP's outlined responsibilities, while D does not.
Reference:
CMMC Assessment Process (CAP) v1.0, Section 2.1 (Roles and Responsibilities), p. 6: "The Assessment Official oversees funding, scope, and plan approval, not operational tasks like escorts."
NEW QUESTION # 86
During the planning and preparation discussions, a key member of the C3PAO Assessment Team falls ill and is unavailable for the originally scheduled assessment dates. The OSC is eager to proceed as planned and has expressed willingness to accommodate a smaller assessment team. Can the Lead Assessor proceed with the assessment using a reduced assessment team size?
- A. Yes, as long as the remaining team members possess the necessary qualifications to cover all CMMC practices.
- B. Yes, but only with the express written consent of the Cyber AB.
- C. No, the assessment must be postponed until the full team is available.
- D. The decision is solely up to the OSC.
Answer: A
Explanation:
Comprehensive and Detailed in Depth Explanation:
The CAP allows flexibility in team size if the remaining members are qualified to cover all practices (Option A). Options B, C, and D impose unnecessary restrictions not supported by CAP.

NEW QUESTION # 87
You are a Lead Assessor tasked with conducting a CMMC Assessment for an OSC seeking to secure its CMMC Level 2 certification. The OSC has previously conducted a self-assessment and engaged a Registered Practitioner Organization (RPO) for a preliminary evaluation. As part of the CMMC Assessment process, you begin by determining the necessary evidence for each practice or process across the OSC's organizational functional areas. You consider both the adequacy and sufficiency of the evidence in relation to the CMMC's requirements. After initial preparations, you and the OSC's POC schedule a joint review session to align on the scope and expectations for the upcoming assessment. What is the primary focus of the 'Sufficiency' criterion during the evidence verification process in a CMMC assessment?
- A. Sufficiency verifies that there is enough evidence to comprehensively assess each practice against the CMMC Assessment scope.
- B. Ensuring the evidence covers a wide range of cybersecurity threats.
- C. Checking if the evidence includes the latest cybersecurity trends and technologies.
- D. Confirming the evidence has been reviewed and approved by all stakeholders.
Answer: A
Explanation:
Comprehensive and Detailed in Depth Explanation:
'Sufficiency' ensures there's enough evidence to assess all practices within scope, not stakeholder approval (Option A), trends (Option C), or threat coverage (Option D). Option B is the CAP focus.

NEW QUESTION # 88
You are the Lead Assessor for a CMMC Level 2 Assessment of an OSC. During Phase 1 planning, the OSC's Assessment Official informs you that several key personnel who manage the in-scope IT systems will be unavailable during the scheduled assessment dates due to a company-wide training event. The Assessment Official asks if the assessment can proceed with substitute personnel who are less familiar with the systems.
What should you do?
- A. Reschedule the assessment to a time when the key personnel are available, as their participation is critical for an accurate assessment.
- B. Proceed with the assessment using the substitute personnel, as long as they can provide some information about the systems.
- C. Agree to proceed but request that the OSC provide written documentation to compensate for the unavailable personnel.
- D. Conduct the assessment virtually to accommodate the unavailable personnel.
Answer: A
Explanation:
Comprehensive and Detailed in Depth Explanation:
The CAP requires interviews and demonstrations with personnel who manage systems, making rescheduling (Option C) necessary. Options A, B, and D compromise assessment accuracy and violate CAP guidelines.
Extract from Official Document (CAP v1.0):
* Section 2.2 - Conduct Assessment (pg. 25):"Interviews and demonstrations must be conducted with the person responsible for carrying out the work." References:
CMMC Assessment Process (CAP) v1.0, Section 2.2.
NEW QUESTION # 89
A contractor is preparing to bid on an upcoming DoD contract to provide next-generation upper limb prosthetics for injured servicemen. Part of the preparation is undergoing a CMMC assessment, and they have hired you to assess their implementation of CMMC practices. The contractor has multiple design, manufacturing, and supply chain management systems. Each system generates its audit logs, which are stored in separate repositories. Different teams analyze and review them independently, with each team reporting the findings to the respective departmental heads. For instance, the engineering team reviews and analyzes logs related to the design systems and reports to the lead engineer, while the operations team focuses on the manufacturing system logs. When interviewing personnel responsible for audit record review, analysis, and reporting, they inform you that this is deliberately set up to ensure departmental independence and granular risk identification. Based on the CMMC practice AU.L2-3.3.5 - Audit Correlation, what is the likely issue you would identify with the contractor's current approach?
- A. The audit review, analysis, and reporting processes are not correlated across systems
- B. Failure to retain audit logs for an adequate duration
- C. Absence of automated mechanisms for analyzing and correlating audit records
- D. Lack of defined processes for audit record review, analysis, and reporting
Answer: A
Explanation:
Comprehensive and Detailed In-Depth Explanation:
AU.L2-3.3.5 requires organizations to "correlate audit record review, analysis, and reporting processes for investigation and response to indications of unlawful, unauthorized, or suspicious activity." The contractor's siloed approach, with separate teams and repositories, lacks correlation across systems, undermining the ability to detect organization-wide patterns or incidents. While departmental independence may aid granular risk identification, it doesn't meet the practice's requirement for integrated correlation. The other options (A, C, D) aren't directly supported by the scenario-processes exist, automation isn't mandated, and retention isn' t addressed.
Extract from Official CMMC Documentation:
* CMMC Assessment Guide Level 2 (v2.0), AU.L2-3.3.5: "Correlate audit record review across systems to support investigation of suspicious activity."

NEW QUESTION # 90
You are the Lead Assessor of a C3PAO assessment team conducting a CMMC assessment for an OSC. The CMMC Assessment Guide - Level 2 lists assessment methods and objects that you are expected to use to validate the OSC's implementation. Which of the following is FALSE about the use of assessment methods and objects?
- A. The Assessment Team has the discretion to use the assessment methods or objects that best fit a CMMC practice during an assessment
- B. A CCA must use all the specified assessment methods and objects while conducting the CMMCassessment
- C. Assessment methods are used to make specific determinations called for in the determination statements
- D. The assessment methods define the nature and extent of the assessor's actions
Answer: B
Explanation:
Comprehensive and Detailed in Depth Explanation:
The CMMC Assessment Guide Level 2 and NIST SP 800-171A allow assessors discretion in selecting methods (examine, interview, test) and objects based on efficiency and context, contradicting Option C's mandate to use all specified items. Option A (specific determinations) and Option B (defining actions) align with NIST definitions. Option D (discretion) reflects the flexibility granted, making Option C false and the correct answer.
Reference Extract:
* CMMC AG Level 2, Section 4.1:"Assessors may select methods and objects best suited to validate practices."
* NIST SP 800-171A, Introduction:"Assessors are not required to use all methods and objects; discretion is allowed."Resources:https://dodcio.defense.gov/Portals/0/Documents/CMMC/AG_Level2_MasterV2.

NEW QUESTION # 91
You are a Lead Assessor working with your C3PAO to conduct a CMMC Assessment for an OSC. During the preparation and planning phase, you meet with the OSC's Assessment Official to identify the resources and schedule for the upcoming assessment. Together, you review the OSC's pre-assessment information to estimate the level of effort required. You then collaborate to determine the specific resources needed, including the Assessment Team members, facilities, and any support personnel from the OSC. You also discuss scheduling factors like duration, key activities, and potential constraints. Based on these discussions, you develop a Rough Order of Magnitude (ROM) cost estimate and a proposed daily schedule for the assessment activities. What is your primary responsibility in identifying resources and schedule during Phase
1?
- A. Determining the overall cost estimate for the assessment.
- B. Verifying that all planning requirements are met when constructing the ROM estimate.
- C. Selecting the assessment team members and their roles.
- D. Finalizing the contract agreement between the C3PAO and OSC.
Answer: B
Explanation:
Comprehensive and Detailed in Depth Explanation:
The CAP designates the Lead Assessor's primary Phase 1 responsibility as ensuring all planning requirements (e.g., scope, resources, schedule) are met for the ROM, not finalizing contracts (Option A), selecting team members (Option B, a C3PAO task), or just cost estimation (Option C). Option D encompasses the full scope.
Extract from Official Document (CAP v1.0):
* Section 1.5 - Assessment Planning (pg. 16):"The Lead Assessor is responsible for verifying that all planning requirements are met when constructing the ROM estimate." References:

NEW QUESTION # 92
A CCA is assessing the concept of least functionality in accordance with CM.L2-3.4.6: Least Functionality.
Which method is the LEAST LIKELY to be useful as an assessment technique?
- A. Interview personnel with information security responsibilities.
- B. Interview personnel with security configuration management responsibilities.
- C. Interview personnel with application development responsibilities.
- D. Interview personnel who wrote the configuration management policy.
Answer: D
Explanation:
To validate least functionality, the assessor must evaluate implementation (via security staff, admins, developers). Interviewing the policy author provides limited value since it does not confirm whether the policy is implemented in practice.
Extract:
"Assessors should confirm least functionality through interviews with individuals responsible for system configuration, security, and implementation. Policy documentation authors alone are not sufficient evidence." Thus, interviewing the policy writer is least useful.
Reference: CMMC Assessment Guide - Level 2, CM.L2-3.4.6.
NEW QUESTION # 93
In assessing an OSC's CUI handling practices, you learn they use an approved algorithm (AES-256) to encrypt the data to ensure its confidentiality. However, the encryption module they are using has not been validated under the FIPS 140 standard. The OSC believes that using an approved algorithm is sufficient to comply with the CMMC practice for CUI encryption requirements. Which of the following would be the most appropriate next step for the assessor?
- A. Interview personnel responsible for cryptographic protection to determine if FIPS-validated cryptography is used elsewhere in the organization
- B. Recommend that the OSC switch to a different, approved algorithm
- C. Accept the OSC's implementation as compliant, given that they are using a strong encryption algorithm
- D. Test the encryption mechanism by attempting to decrypt the encrypted data without the proper keys
Answer: A
Explanation:
Comprehensive and Detailed In-Depth Explanation:
SC.L2-3.13.11 requires "FIPS-validated cryptography for CUI." AES-256 alone isn't sufficient without FIPS
140 validation. Interviewing personnel (A) clarifies if validated cryptography is used elsewhere, aiding compliance assessment. Testing decryption (B) is impractical, switching algorithms (C) misses the validation issue, and accepting (D) ignores FIPS requirements. The CMMC guide prioritizes interviews for evidence gathering.
Extract from Official CMMC Documentation:
* CMMC Assessment Guide Level 2 (v2.0), SC.L2-3.13.11: "Interview personnel to verify FIPS- validated cryptography usage."
* NIST SP 800-171A, 3.13.11: "Assess cryptographic practices via interviews." Resources:

NEW QUESTION # 94
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 centralized IT department
- B. The Manufacturing Division
- C. The Manufacturing Division and the centralized IT department
- D. The entire aerospace company
Answer: B
Explanation:
Comprehensive and Detailed Explanation:
The CMMC Assessment Scope - Level 2 designates the Host Unit (OSC) as the unit directly performing the DoD contract work-in this case, the Manufacturing Division. The centralized IT department, as a Supporting Organization, is assessed only if it processes, stores, or transmits CUI or provides security for the Host Unit, which is not indicated for administrative tasks. Option C overextends the scope, and Option D is too broad. A is correct.
Reference:
CMMC Assessment Scope - Level 2, Section 2.1 (Host Unit), p. 3: "The Host Unit is assessed for compliance."
NEW QUESTION # 95
Both FCI and CUI are stored by an OSC on the same network. Server A contains file shares with FCI, and Server B contains file shares with CUI. The OSC hopes each server would only undergo the assessment for the classification of data it contains. What is the MOST correct assessment situation in this scenario?
- A. Due to the presence of CUI on the network, a Level 2 certification is required for the network
- B. Due to the presence of FCI on the network, only a Level 1 self-assessment is required for the network
- C. Server A may undergo a Level 1 self-assessment, while Server B must obtain a Level 2 certification
- D. The network must be segmented to separate FCI from CUI before any assessments can be conducted
Answer: A
Explanation:
When CUI and FCI reside on the same network, the entire environment is considered a CUI environment.
The presence of CUI drives the assessment requirement to CMMC Level 2, regardless of whether FCI also exists. Assets cannot be assessed separately under Level 1 vs. Level 2 within the same network boundary.
Exact extracts:
* "If CUI is processed, stored, or transmitted within an environment, the environment is in scope for CMMC Level 2."
* "The presence of CUI dictates the assessment level, regardless of whether FCI is also present."
* "Segmentation may reduce scope, but if assets remain within the same environment, all assets fall under Level 2." Why other options are incorrect:
* B: Level 1 cannot be applied to Server A while Server B undergoes Level 2 in the same network.
* C: Presence of CUI means Level 2 is required, not Level 1.
* D: Segmentation can reduce scope but is not required before assessment; it is an OSC design choice.

NEW QUESTION # 96
A vulnerability scan on a defense contractor's system identifies a critical security flaw in a legacy database application that stores CUI. Remediating the flaw would require a complete overhaul of the application, causing significant downtime and potentially disrupting critical business functions. Given the potential consequences of remediation, the contractor is considering deferring the fix. Which course of action best aligns with the guidance of CMMC practice RA.L2-3.11.3 - Vulnerability Remediation?
- A. Immediately contract a third party to assist with remediation
- B. Permanently disregard the vulnerability and take no further action
- C. Document the risk acceptance rationale and continue monitoring the risk from the vulnerability
- D. Implement compensating controls to reduce the associated risk
Answer: C
Explanation:
Comprehensive and Detailed In-Depth Explanation:
RA.L2-3.11.3 requires "remediating vulnerabilities in accordance with risk assessments." If remediation isn't feasible, the practice allows risk acceptance with documentation and ongoing monitoring, balancing operational needs and security. Ignoring the vulnerability (C) violates the practice, while third-party help (A) or compensating controls (D) may not be immediately practical. The CMMC guide supports risk-based decisions with proper documentation.
Extract from Official CMMC Documentation:
* CMMC Assessment Guide Level 2 (v2.0), RA.L2-3.11.3: "Document risk acceptance and monitor unremediated vulnerabilities."
* NIST SP 800-171A, 3.11.3: "Examine risk acceptance rationale and monitoring plans." Resources:

NEW QUESTION # 97
A CCA witnesses another CCA from their C3PAO team flirting with an OSC employee during a social event after completing the assessment. According to the CoPC, what is the most appropriate course of action for the observing CCA?
- A. Ignore the situation, as it doesn't impact the assessment.
- B. Publicly confront the other CCA about their unprofessional behavior.
- C. Discreetly remind the other CCA of the CoPC's harassment and discrimination guidelines.
- D. Report the incident directly to the Cyber AB.
Answer: C
Explanation:
Comprehensive and Detailed in Depth Explanation:
The CMMC Code of Professional Conduct (CoPC) prohibits harassment and discrimination in all interactions related to CMMC roles, including post-assessment social events. The observing CCA must act professionally and ethically. Option A (reporting to Cyber AB) escalates prematurely without attempting internal resolution, which the CoPC encourages first. Option C (ignoring) fails to address a potential violation, breaching the CCA's duty to uphold the CoPC. Option D (public confrontation) risks unprofessional escalation. Option B (discreet reminder) aligns with CoPC's emphasis on addressing violations internally and professionally, allowing the offending CCA to correct their behavior while maintaining team integrity.
Extract from Official Document (CoPC):
* Paragraph 3.6(2) - Lawful and Ethical Practices (pg. 8):"Refrain from harassment ordiscrimination, sexual or otherwise, in all interactions with individuals encountered in connection with activities related to your role in the CMMC ecosystem."
* Paragraph 4.1(1)(a) - Violation Reporting (pg. 10):"Attempt to rectify the violation with the individual or entity in question prior to reporting." References:
CMMC Code of Professional Conduct, Paragraphs 3.6(2) and 4.1(1)(a).
NEW QUESTION # 98
During a CMMC assessment of an OSC, you discover that they rely heavily on a reputable CSP for their email services. As you delve deeper into the assessment, you suspect the OSC is incorrectly assuming that the CSP's security measures are sufficient to meet all the CMMC requirements related to email security. Given the critical nature of email communications and the potential exposure of sensitive information, you recognize the importance of clearly understanding the division of responsibilities between the OSC and the CSP for email security controls. To effectively assess how email security responsibilities are divided between the OSC and the CSP, which document should you prioritize reviewing?
- A. The CSP's publicly available security documentation
- B. The OSC's overall security policy
- C. The Service Level Agreement (SLA) between the OSC and the CSP
- D. The Shared Responsibility Matrix (SRM) between the OSC and the CSP
Answer: D
Explanation:
Comprehensive and Detailed in Depth Explanation:
The Shared Responsibility Matrix (SRM), per CMMC and FedRAMP guidance, delineates security control responsibilities between the OSC and CSP, critical for assessing email security (e.g., AC.L2-3.1.13). Option A (security policy) lacks CSP-specific detail. Option C (public documentation) is generic, not contractual.
Option D (SLA) focuses on service levels, not control specifics. Option B is the correct answer, providing the clearest division per CAP.
Reference Extract:
* CMMC Assessment Process (CAP) v1.0, Section 4.3:"The SRM clarifies CSP and OSC responsibilities for cloud services."Resources:https://cyberab.org/Portals/0/Documents/Process-Documents/CMMC- Assessment-Process-CAP-v1.0.pdf
NEW QUESTION # 99
You are part of the Assessment Team evaluating an OSC's implementation of AC.L2-3.1.13 - Remote Access Confidentiality. This requirement mandates the organization to employ cryptographic mechanisms to protect the confidentiality of remote access sessions. During your assessment, you want to determine whether these cryptographic mechanisms have been properly identified as required by assessment objective [a]. What specification can you use to make this determination?
- A. Remote access authorizations
- B. Interviews with security administrators
- C. The organization's Access Control Policy and Procedures and system design documentation
- D. Interviews of personnel responsible for remote access
Answer: C
Explanation:
Comprehensive and Detailed in Depth Explanation:
AC.L2-3.1.13[a] requires the OSC to identify cryptographic mechanisms protecting remote access session confidentiality, per NIST SP 800-171A and CMMC Level 2 guidelines. The organization's Access Control Policy and Procedures outline the standards and requirements for cryptography (e.g., FIPS-validated modules), while system design documentation details the specific mechanisms implemented (e.g., TLS, VPN configurations). These documents directly address the identification of cryptographic controls, making them the primary specifications for this objective.
Option A and B (interviews) provide supplementary insights but lack the authoritative detail of written policies and designs. Option C (remote access authorizations) focuses on permissions, not cryptographic mechanisms. Option D is the correct answer, as it aligns with NIST SP 800-171A'semphasis on examining specifications for objective [a].
Reference Extract:
* NIST SP 800-171A, AC-3.1.13[a]:"Examine access control policy; procedures addressing remote access... system design documentation to determine if cryptographic mechanisms are identified."
* CMMC AG Level 2, AC.L2-3.1.13:"Verify cryptographic mechanisms via policy and design specs." Resources:https://csrc.nist.gov/pubs/sp/800/171/a/final;https://dodcio.defense.gov/Portals/0/Documents

NEW QUESTION # 100
An OSC plans to bid for a DoD contract to supply laser welding services to repair a fleet of unmanned aerial vehicles (UAVs). This requires them to be CMMC Level 2 certified since the information they will receive from the DoD is Controlled Technical Information (CTI). However, their repair and welding services require a Computer Numerical Control (CNC) machine to fabricate some crucial parts. Since the welding is mainly automated using robots, the OSC has intelligently integrated its SCADA system with Programmable Logic Controllers (PLCs) for increased accuracy, improved safety and efficiency, and enhanced flexibility. If the OSC wins the contract, how will the banner marking on documents containing CUI from the DoD be structured?
- A. CUI/SP-CTI
- B. CUI-SP//CTI
- C. CUI//CTI
- D. CUI//SP-CTI
Answer: D
Explanation:
Comprehensive and Detailed Explanation:
Controlled Technical Information (CTI), per the NARA CUI Registry, is a CUI-specified category requiring the banner marking "CUI//SP-CTI." The double forward slash (//) separates the base CUI designation from the specified category (SP-CTI), per CUI marking guidelines. Option B lacks the specified designation, Option C uses an incorrect single slash, and Option D reverses the structure. A is correct.
Reference:
NARA CUI Registry: CTI Category -https://www.archives.gov/cui/registry/category-detail/export-control.
html: "CTI is marked CUI//SP-CTI."
