質問 # 89
As the Lead Assessor for your Assessment Team, you are validating an OSC's scope in readiness to start the assessment. You learn that the OSC provides its employees with laptops to work on DoD projects. These laptops have an antivirus solution that connects to a management console to receive updates, send alerts, and control settings. However, the server does not process, store, or transmit CUI but implements several CMMC controls. Which of the following is NOT part of the OSC's requirements regarding the antivirus solution?
- A. The OSC should document it in the System Security Plan (SSP).
- B. They should document the specifics of the antivirus solution in the asset inventory.
- C. Itemize the solution in the CMMC Assessment Scope's network diagram and prepare it to be assessed against CMMC practices.
- D. Logically separate the antivirus solution from other CUI assets.
正解：D
解説：
Comprehensive and Detailed Explanation:
The antivirus solution is a Security Protection Asset (SPA), per the CMMC Assessment Scope - Level 2, requiring documentation in the network diagram (Option A), asset inventory (Option B), and SSP (Option C), and assessment against CMMC practices. Logical separation (Option D) is not required for SPAs, which must integrate with the CUI environment to function. D is not a requirement.
Reference:
CMMC Assessment Scope - Level 2, Section 2.3.3 (SPAs), p. 6: "SPAs are documented and assessed, not separated from CUI assets."
質問 # 90
To comply with CMMC requirement IR.L2-3.6.3 - Incident Response Testing, organizations seeking certification (OSCs) must have a plan to regularly test their ability to respond to cyber incidents. This testing ensures that OSCs can effectively identify, contain, and recover from security breaches. An OSC can cite the following evidence artifacts to show compliance with the practice, EXCEPT?
- A. Evidence of regular incident response drills and response time management, recovery testing, and post- incident analysis
- B. Media sanitization plans
- C. Test documentation, including the scenario, response, findings, and any necessary corrective actions
- D. Documentation of tabletop exercises and their outcomes
正解：B
解説：
Comprehensive and Detailed In-Depth Explanation:
IR.L2-3.6.3 requires "testing the incident response capability annually." Artifacts like drills (A), tabletop exercises (C), and test documentation (D) demonstrate testing execution and outcomes, aligning with the practice. Media sanitization plans (B) relate to MP.L2-3.8.3, not incident response testing, making it irrelevant. The CMMC guide lists response-focused evidence.
Extract from Official CMMC Documentation:
* CMMC Assessment Guide Level 2 (v2.0), IR.L2-3.6.3: "Examine test records, drills, and tabletop exercise outcomes."
* NIST SP 800-171A, 3.6.3: "Artifacts focus on response testing, not sanitization." Resources:

質問 # 91
During your review of an OSC's system security control, you focus on CMMC practice SC.L2-3.13.9 - Connections Termination. The OSC uses a custom web application for authorized personnel to access CUI remotely. Users log in with usernames and passwords. The application is hosted on a dedicated server within the company's internal network. The server operating system utilizes default settings for connection timeouts.
Network security is managed through a central firewall, but no specific rules are configured for terminating inactive connections associated with the CUI access application. Additionally, there is no documented policy or procedure outlining a defined period of inactivity for terminating remote access connections. Interviews with IT personnel reveal that they rely solely on users to remember to log out of the application after completing their work. Based on the scenario, what is the MOST concerning aspect from a CMMC compliance perspective regarding CMMC practice SC.L2-3.13.9 - Connections Termination?
- A. The server operating system utilizes default settings for connection timeouts, which may be insufficient
- B. Users log in with usernames and passwords, potentially lacking multi-factor authentication
- C. The lack of a documented policy or a defined period of inactivity for terminating remote access connections creates uncertainty and inconsistency
- D. The application is hosted on a dedicated server within the company's internal network
正解：C
解説：
Comprehensive and Detailed In-Depth Explanation:
SC.L2-3.13.9 requires "terminating connections after a defined period of inactivity." The absence of a documented policy and defined inactivity period (C) is most concerning, as it fails the practice's core requirement, leaving termination inconsistent and user-dependent. Hosting location (A) is neutral, MFA (B) relates to AC.L2-3.1.3, and default timeouts (D) are a symptom of the policy gap. The CMMC guide prioritizes defined inactivity controls.
Extract from Official CMMC Documentation:
* CMMC Assessment Guide Level 2 (v2.0), SC.L2-3.13.9: "Define and document inactivity period for termination; lack thereof is non-compliant."
* NIST SP 800-171A, 3.13.9: "Examine policy for defined inactivity period." Resources:

質問 # 92
In an effort to understand whether the OSC appropriately defined the scope to exclude items that should not be assessed, which description does NOT belong in the scope?
- A. A smoke detector that is connected to the OSC network
- B. The office where its managed service provider's management office is located
- C. Data center in another state used by the OSC
- D. The SIEM tool used by the managed service provider in managing the OSC
正解：A
解説：
CMMC scoping focuses on assets that process, store, transmit, or protect CUI. A smoke detector connected to the OSC network is an IoT device with no impact on CUI, so it is considered Out-of-Scope. The other items (data centers used by the OSC, MSP SIEM tools, and MSP offices handling OSC management) all directly affect the OSC's CUI environment and therefore fall within scope.
Exact extracts:
* "CUI Assets are those that process, store, or transmit CUI."
* "Security Protection Assets are those that provide security functions for CUI Assets."
* "External Service Providers (e.g., MSPs, data centers, SIEMs) that support CUI Assets are in-scope."
* "Assets that cannot affect the confidentiality of CUI (e.g., unrelated IoT devices) are considered Out-of- Scope." Expanded explanation:
* Data centers (A): If OSC CUI is stored or processed there, they are in-scope.
* SIEM tools (C): Provide security monitoring of OSC networks - a clear Security Protection Asset.
* MSP office (D): MSPs providing services that affect CUI are in-scope, including their management locations.
* Smoke detector (B): Despite being network-connected, it does not interact with CUI or provide protective functions; it is explicitly out-of-scope.
Why the other options are in scope:
* They either process, protect, or manage CUI directly.
* Excluding them would improperly narrow the assessment boundary.

質問 # 93
When assessing an OSC's implementation of the System and Information Integrity (SI) practices, you examine their system and information integrity policy. You find that they have documented procedures addressing system monitoring tools and techniques, along with a monitoring strategy. The OSC has implemented a user behavior analytics tool to detect abnormal behavior anddeviations from normal patterns.
To ensure that only authorized users access the system, the OSC uses robust access controls and regularly audits security and system logs for unusual activities. Interviewing the network administration team, you learn they use a network monitoring tool to track inbound and outbound network traffic and identify any distinctive patterns that may suggest unauthorized use. You also learn that they use an IDS to identify suspicious activities, which are aggregated and analyzed using a state-of-the-art SIEM. The scenario mentions that the OSC uses a network monitoring tool to track inbound and outbound traffic and identify unusual patterns.
However, it does not provide details on the tool's specific techniques or methods. Which of the following techniques would be most relevant for the assessor to inquire about during the assessment?
- A. Both signature-based and anomaly-based detection techniques
- B. Deep packet inspection techniques
- C. Signature-based detection techniques
- D. Anomaly-based detection techniques
正解：A
解説：
Comprehensive and Detailed In-Depth Explanation:
CMMC practice SI.L2-3.14.6 - Monitor Communications for Attacks requires organizations to "monitor organizational communications at external boundaries and key internal boundaries for attacks or indicators of potential attacks." Effective monitoring typically employs bothsignature-based detection(identifying known threats via predefined patterns) andanomaly-based detection(flagging deviations from normal behavior), as these complementary techniques provide comprehensive coverage against known and emerging threats. The OSC's use of IDS, SIEM, and user behavior analytics suggests a mix of capabilities, but the specific techniques aren't detailed. Inquiring about both (C) ensures the assessor verifies a robust approach, as recommended by the CMMC guide. Anomaly-based (A) or signature-based (B) alone are insufficient, and while deep packet inspection (D) is useful, it's a narrower method not explicitly required.
Extract from Official CMMC Documentation:
* CMMC Assessment Guide Level 2 (v2.0), SI.L2-3.14.6: "Monitoring includes signature-based and anomaly-based detection to identify attacks."
* NIST SP 800-171A, 3.14.6: "Interview personnel to determine monitoring techniques, including signature and anomaly detection." Resources:

質問 # 94
You are the Lead Assessor of the Assessment Team conducting a CMMC Level 2 assessment for an OSC.
You have completed the first phase of the assessment process, which included the assessment kickoff meeting. Now, you are moving into the second phase, which involves collecting and examining evidence to determine the OSC's compliance with the CMMC practices. During the evidence collection phase, you need to examine the OSC's policies and procedures related to the CMMC practice AC.L2-3.1.5 - Least Privilege.
Which of the following would be an appropriatesource of evidence for this practice?
- A. Testing the OSC's Role-Based Access Control (RBAC) and Privilege Access Management (PAM) tools.
- B. Interviewing the system administrators about their daily activities.
- C. Examining the organization's system configuration documentation.
- D. Observing the system administrators as they configure the systems.
正解：C
解説：
Comprehensive and Detailed in Depth Explanation:
For AC.L2-3.1.5 (Least Privilege), the CAP emphasizes documented policies and procedures as primary evidence to demonstrate compliance with the practice's intent. Examining system configuration documentation (Option C) directly shows how least privilege is implemented, aligning with the CAP's guidance on the 'Examine' method. Option A (testing RBAC/PAM) assesses technical implementation, not policies. Option B (observing admins) is less systematic and not policy-focused. Option D (interviewing admins) provides supplementary insights but not the core evidence required.
Extract from Official Document (CAP v1.0):
* Section 2.2 - Conduct Assessment (pg. 25):"Examination includes reviewing documented policies, procedures, and system configurations to assess compliance with CMMC practices." References:
CMMC Assessment Process (CAP) v1.0, Section 2.2.
質問 # 95
An OSC undergoing a CMMC Level 2 assessment provides evidence that includes a third-party audit report from a previous year. The report indicates compliance with several CMMC practices, but it does not address the current state of the OSC's systems. How should the Lead Assessor treat this evidence?
- A. Use the audit report as partial evidence and request additional current evidence to verify ongoing compliance.
- B. Accept the audit report as sufficient evidence for the practices it covers.
- C. Mark all practices covered by the report as "NOT MET" due to the lack of current data.
- D. Reject the audit report as outdated and request current evidence.
正解：A
解説：
Comprehensive and Detailed in Depth Explanation:
The CAP allows historical evidence if supplemented with current data (Option C). Options A, B, and D misapply evidence evaluation rules.

質問 # 96
A software development company uses a cloud-based source code repository and continuous integration
/continuous deployment (CI/CD) platform to manage its software development lifecycle. The cloud service provider hosts and manages the source code repository and CI/CD platform. Which of the following statements accurately describes how the OSC should handle the cloud service provider's assets in the CMMC Assessment Scope?
- A. It depends on the contract between the company and the cloud provider.
- B. Include the cloud service provider's assets in the certification boundary but exclude them from the assessment scope.
- C. Exclude the cloud provider's assets from the Assessment Scope since they are not owned or managed by the company.
- D. Include the cloud provider's assets in the Assessment Scope as they handle sensitive code.
正解：D
解説：
Comprehensive and Detailed Explanation:
The CMMC Assessment Scope - Level 2 requires that External Service Provider (ESP) assets, like the cloud- based repository and CI/CD platform, be included in the scope if they process, store, or transmit CUI/FCI (e.
g., sensitive code under a DoD contract). Ownership is irrelevant; function dictates inclusion. Option A contradicts this, Option C misaligns boundary and scope definitions, and Option D introduces unnecessary ambiguity. B is correct.
Reference:
CMMC Assessment Scope - Level 2, Section 2.3.3 (ESPs), p. 6: "ESP assets handling CUI/FCI are in scope."
質問 # 97
The client has a Supervisory Control and Data Acquisition (SCADA) system as OT to be evaluated as part of its assessment. In reviewing network architecture and conducting interviews, the assessor determines that a firewall separates the SCADA system from the client's enterprise network and that CUI is not processed by the SCADA system. Based on this information, what is an appropriate outcome?
- A. The assessor determines the SCADA system is out-of-scope for the assessment
- B. The assessor determines that all Specialized Assets are within the scope of the assessment
- C. The assessor includes the OT within the assessment
- D. The assessor includes all systems identified by the client as part of the assessment
正解：A
解説：
In CMMC scoping, only assets that process, store, or transmit CUI (CUI Assets) or that can access them (Security Protection, Contractor Risk Managed, Specialized Assets) are in-scope. Since the SCADA system is firewalled off and does not handle CUI, it does not fall under CUI Asset classification and is considered Out- of-Scope.
Exact extracts:
* "CUI Assets are those that process, store, or transmit CUI."
* "Assets that do not process, store, or transmit CUI and have no connectivity to CUI Assets are considered Out-of-Scope."
* "Specialized Assets... are only in-scope if they process, store, or transmit CUI." Why the other options are incorrect:
* A: Inclusion requires processing/storing/transmitting CUI.
* C: OSC cannot arbitrarily bring unrelated systems into scope; CUI relevance governs scope.
* D: Not all Specialized Assets are in-scope; only those with CUI interaction are.

質問 # 98
An aerospace company has requested a CMMC assessment for an enclave only. Your team has verified that the company has a valid CAGE code and is registered with SAM.gov. However, the enclave has no separate CAGE code or SAM registration. Can the assessor proceed with the CMMC assessment solely for the enclave, or is an assessment of the entire aerospace company's network required?
- A. The assessor can proceed with the enclave assessment for CMMC Level 2 compliance.
- B. The assessor must assess the entire company network.
- C. The assessor can proceed with the enclave assessment, but only for a lower CMMC level.
- D. The assessor cannot proceed with the enclave assessment.
正解：A
解説：
Comprehensive and Detailed Explanation:
The CMMC Assessment Process (CAP) allows for assessments of specific enclaves within an organization, defined as a segmented set of system resources sharing a common security perimeter. The CMMC Assessment Scope - Level 2 supports this by permitting the scope to be limited to an enclave if it fully contains the CUI environment and is properly isolated. While a CAGE code and SAM registration are required for the parent organization (the aerospace company), they are not mandated for individual enclaves within that entity. Since the company has these credentials, the assessor can proceed with a Level 2 assessment of the enclave, provided its isolation and security controls are verified.
Option B is incorrect as no rule prohibits enclave-only assessments. Option C is too broad, contradicting segmentation allowances. Option D misapplies level restrictions. A is correct per the CAP and scoping guide.
Reference:
CMMC Assessment Process (CAP) v1.0, Section 2.1 (Assessment Scoping), p. 8: "An enclave can be assessed independently if it meets isolation requirements." CMMC Assessment Scope - Level 2, Section 2.2 (Enclave Scoping)
質問 # 99
An OSC previously received a Conditional CMMC Level 2 Certification during Phase 3 of the assessment process. The OSC has been working on implementing a POA&M to address the practice deficiencies identified during the initial assessment. Now, within 180 days from the Final Recommended Findings Briefing, you are to conduct a POA&M Closeout Assessment. As the Lead Assessor, you and your assessment team review the OSC's updated POA&M, accompanying evidence, and any scheduled observations, interviews, or tests with the aim of validating the implementation of the corrective actions. If the Organization Seeking Certification (OSC) disagrees with the C3PAO's findings during the POA&M Closeout Assessment, what is the recourse?
- A. Demand a reassessment by the same C3PAO and Lead Assessor.
- B. Request an extension of the timeline for corrective actions.
- C. Submit an appeal using the Assessment Appeals Process outlined in the CAP.
- D. Immediately reapply for CMMC Level 2 certification with a different C3PAO.
正解：C
解説：
Comprehensive and Detailed in Depth Explanation:
The CAP provides a formal Assessment Appeals Process for OSCs to dispute C3PAO findings, ensuring fairness and due process. Option A (reapplying with another C3PAO) bypasses resolution and incurs unnecessary costs. Option C (requesting extension) addresses timing, not disagreement with findings. Option D (demanding reassessment) lacks CAP support without an appeal. Option B is the prescribed recourse.
Extract from Official Document (CAP v1.0):
* Section 3.3 - Assessment Appeals Process (pg. 34):"If the OSC disagrees with the C3PAO's findings, they may submit an appeal using the Assessment Appeals Process outlined in this CAP." References:

質問 # 100
Sarah, a Certified CMMC Assessor, is conducting an assessment for DataSecure, a cloud service provider that hosts various applications for the Defense Industrial Base (DIB). During the assessment, Sarah encounters a complex and highly specialized cloud architecture that leverages cutting-edge technologies such as containerization, serverless computing, and advanced security controls. As Sarah reviews the evidence provided by DataSecure for the relevant CMMC practices, she realizes that some of the evidence and implementations are unlike anything she has encountered in previous assessments. What is the most appropriate action for Sarah to take as a CCA in this scenario?
- A. Thoroughly research and understand DataSecure's cloud architecture, seek clarification from subject matter experts, and evaluate the evidence within the context of their specialized environment.
- B. Defer the assessment until she can receive additional training on the specific technologies used by DataSecure.
- C. Strictly adhere to a standardized assessment checklist, regardless of DataSecure's unique architecture.
- D. Request DataSecure to simplify their architecture and align with more traditional IT practices for easier evaluation.
正解：A
解説：
Comprehensive and Detailed in Depth Explanation:
The CAP requires assessors to adapt to unique implementations by researching and understanding them, not forcing simplification (Option A), ignoring context (Option B), or delaying unnecessarily (Option C). Option D ensures a thorough, context-aware assessment.
Extract from Official Document (CAP v1.0):
* Section 2.2 - Conduct Assessment (pg. 25):"Assessors shall research and understand unique implementations, seeking clarification from SMEs as needed." References:

質問 # 101
Your C3PAO has selected you as the Lead Assessor for the Assessment Team assessing an OSC's implementation of CMMC practices. Part of this assessment includes validating the OSC's CMMC assessment scope. Which of the following is NOT a factor to consider when determining which assets are in scope?
- A. Organizational assets that process CUI or FCI.
- B. Third-party assets that store CUI or FCI.
- C. Government assets transmitting CUI into the OSC's systems.
- D. Assets that secure the CUI or FCI storage location.
正解：C
解説：
Comprehensive and Detailed Explanation:
The CMMC Assessment Scope - Level 2 includes assets under the OSC's control that process, store, or transmit CUI/FCI (Option B), secure these assets (Option C), or are managed by third parties (e.g., ESPs) handling CUI/FCI (Option D). Government assets transmitting CUI into the OSC's systems (Option A) are out of scope, as they fall under a separate government authorization boundary and are not managed by the OSC. The scoping guide explicitly excludes such assets, making A the correct answer.
Reference:
CMMC Assessment Scope - Level 2, Section 2.3.5 (Out-of-Scope Assets), p. 7: "Government assets transmitting CUI into OSC systems are out of scope."
質問 # 102
An OSC is preparing for an assessment and wants to gather evidence that will be used by the Lead Assessor to determine the scope of the assessment. The OSC currently operates a hybrid network, with part of their infrastructure at their physical location and part of their infrastructure in a cloud environment.
What evidence should the OSC collect that would assist the Lead Assessor in determining cloud and hybrid environment constraints?
- A. System inventory
- B. Subnetworks list
- C. Cloud Service Provider's Customer Responsibility Matrix
- D. Company-owned hardware list
正解：C
解説：
For hybrid and cloud environments, the Customer Responsibility Matrix is the critical artifact. It identifies which security responsibilities are handled by the CSP and which remain with the OSC, directly impacting scope.
Extract:
"The OSC must provide responsibility matrices or equivalent documentation that clearly delineates which security controls are the responsibility of the provider and which are retained by the OSC." This is necessary for the Lead Assessor to define assessment scope boundaries.
Reference: CMMC Assessment Guide - Level 2; Scoping Guidance for Cloud and Hybrid Environments.
質問 # 103
An organization's password policy includes these requirements:
* Passwords must be at least 8 characters in length.
* Passwords must contain at least one uppercase character, one lowercase character, and one numeric digit.
* Passwords must be changed at least every 90 days.
* When a password is changed, none of the previous 3 passwords can be reused.
Per IA.L2-3.5.7: Password Complexity, what requirement is missing from this password policy?
- A. It does not require the password to contain at least one special character.
- B. It does not require MFA.
- C. It does not include a list of prohibited passwords.
- D. It does not specify a minimum change of character requirement.
正解：A
解説：
IA.L2-3.5.7 requires password complexity rules that include uppercase, lowercase, numeric, and special characters. The given policy addresses three requirements but does not mandate at least one special character.
Extract:
"Enforce password complexity by requiring combinations of upper-case letters, lower-case letters, numbers, and special characters." Thus, the missing requirement is the use of a special character.
Reference: CMMC Assessment Guide - Level 2, IA.L2-3.5.7.
質問 # 104
You are the Lead Assessor conducting a CMMC assessment for an OSC. During the initial stages ofthe assessment, the OSC provided a comprehensive list of evidence sources, including various documents, policies, and procedures. However, as the assessment progresses, you notice that the OSC has started to rely more heavily on demonstrations and live system tests to showcase their compliance with certain CMMC practices. While these demonstrations and tests provide valuable insights, they deviate from the originally planned approach of primarily relying on documented evidence. This change in the evidence collection approach could potentially impact the assessment timeline and the overall assessment plan. As the Lead Assessor, what should you do in response to this change in the evidence collection approach?
- A. Document the change in the evidence collection approach by updating the Pre-Assessment Data Form and exporting the updated file to CMMC eMASS while continuing with the assessment as appropriate.
- B. Request the OSC to revert to the originally planned approach citing the agreed-to and planned approach documented in the Assessment Plan.
- C. Pause the assessment until a revised assessment plan can be developed to accommodate the increased reliance on demonstrations and live system tests.
- D. Proceed with the assessment as planned, after all, the OSC is providing evidence.
正解：A
解説：
Comprehensive and Detailed in Depth Explanation:
The CAP requires documenting significant changes to the evidence collection approach in the Pre-Assessment Data Form and updating CMMC eMASS to maintain transparency and traceability. Option A (proceeding without documentation) risks misalignment with the CAP's record-keeping requirements. Option C (reverting) is overly rigid, as demonstrations and tests are valid methods per CAP. Option D (pausing) is unnecessary unless the change fundamentally disrupts the assessment. Option B ensures compliance with CAP while allowing flexibility.
Extract from Official Document (CAP v1.0):
* Section 1.6 - Prepare for Assessment (pg. 18):"Significant changes to the evidence collection approach shall be documented by updating the Pre-Assessment Data Form and exporting the updated file to CMMC eMASS." References:

The OSC has been working on implementing a POA&M to address the practice deficiencies identified during the initial assessment. Now, within 180 days from the Final Recommended Findings Briefing, you are to conduct a POA&M Closeout Assessment. As the Lead Assessor, you and your assessment team review the OSC's updated POA&M, accompanying evidence, and any scheduled observations, interviews, or tests with the aim of validating the implementation of the corrective actions. If any practices on the POA&M review fail to result in a score of 'MET,' what should the Lead Assessor recommend?
- A. Update the POA&M with the remaining practice deficiencies for the OSC to address.
- B. Recommend the OSC NOT be recommended for CMMC Level 2 Final Certification.
- C. Extend the timeframe for the OSC to address the remaining practice deficiencies.
- D. Conduct a follow-up assessment to review the remaining practice deficiencies.
正解：B
解説：
Comprehensive and Detailed in Depth Explanation:
The CAP mandates that if any POA&M practices fail to score 'MET' during the Closeout Assessment, the Lead Assessor must recommend against Final Certification, requiring the OSC to reapply after corrections.
Options A, C, and D do not align with this requirement.
Extract from Official Document (CAP v1.0):
* Section 3.4 - POA&M Closeout Assessment (pg. 35):"If any practices on the POA&M Review fail to result in a score of 'MET,' the Lead Assessor will recommend that the OSC NOT be recommended for CMMC Level 2 Final Certification." References:

During the Planning phase, the C3PAO and Lead Assessor will collect information from the OSC to provide a Rough Order of Magnitude (ROM). This enables the Assessor to approximate the duration, schedule, and cost of the Assessment. To determine the Rough Order of Magnitude (ROM), the Lead Assessor can use the following inputs, EXCEPT?
- A. The OSC's readiness.
- B. The OSC's location and number of facilities.
- C. The size and complexity of the OSC.
- D. Education levels of the Assessment Team.
正解：D
解説：
Comprehensive and Detailed in Depth Explanation:
The CAP lists OSC-related inputs for ROM (Options A, C, D), but team education (Option B) is irrelevant to this estimate.
Extract from Official Document (CAP v1.0):

質問 # 107
An OSC is preparing for a CMMC assessment. It has multiple information systems, some of which process CUI and others that do not. The OSC has identified a specific system that processes CUI and defined this as its system boundary. However, this system is connected to other systems within the OSC that are separately authorized and do not process CUI. As a Certified CMMC Assessor, which of the following best describes your approach to defining the CMMC Certification Boundary and Assessment Scope for the OSC?
- A. The CMMC Certification Boundary should include the specific system that processes CUI. In contrast, the Assessment Scope should consist of all components of the information system that require authorization and excludes separately authorized systems to which the information system is connected.
- B. The CMMC Certification Boundary and Assessment Scope should only include the specific system that processes CUI and exclude all other systems.
- C. The CMMC Certification Boundary and Assessment Scope should include all information systems within the organization, regardless of whether they process CUI or not.
- D. The CMMC Certification Boundary should include the specific system that processes CUI, while the Assessment Scope should encompass all systems within the OSC.
正解：A
解説：
Comprehensive and Detailed Explanation:
The CMMC Assessment Process (CAP) distinguishes the Certification Boundary (the CUI-processing system) from the Assessment Scope (all components needing authorization, excluding separately authorized connected systems). The scoping guide and glossary confirm that separately authorized systems are out of scope, aligning with Option D. Option A is too broad, Option B too narrow, and Option C reverses the definitions. D is correct.
Reference:
CMMC Assessment Process (CAP) v1.0, Section 2.1 (Certification Boundary), p. 8: "The Assessment Scope excludes separately authorized systems."
質問 # 108
Before an OSC categorizes its assets into different categories, it must determine the scope of applicability.
However, after discussing with the OSC's Point of Contact (PoC), you learn that although they follow CUI and FCI in all forms and stages, they are mostly considered technical components. What is the issue with the OSC's approach to determining the scope of applicability?
- A. The OSC's approach may result in a scope that is too broad for the assessment.
- B. They have fallen into the "technical system" trap.
- C. The OSC's approach focuses on saving money by narrowing the scope.
- D. The OSC's approach might result in too many CUI assets.
正解：B
解説：
Comprehensive and Detailed Explanation:
The CMMC framework, aligned with NIST SP 800-171, is information-centric, meaning the scope of applicability includes all systems, people, processes, and facilities where CUI and FCI flow-not just technical components. The OSC's focus on technical systems alone indicates they've fallen into the "technical system" trap, overlooking human-centric processes (e.g., contract proposals, physical media) and broader lifecycle stages where CUI exists. This narrow view risks excluding critical assets and underestimating the full scope, as defined in the CMMC Assessment Scope - Level 2.
Option A is a potential outcome, not the issue. Option B assumes intent not provided in the scenario. Option C contradicts the narrow focus described. D correctly identifies the scoping error per CMMC guidance.
Reference:
CMMC Assessment Scope - Level 2, Section 2.1 (Scoping Guidance), p. 3: "The scope includes people, processes, and facilities, not just technical systems."
