    A. Members of the OSC that will be providing evidence.
    B. The Lead Assessor.
    C. The OSC PoC.
    D. The CMMC Quality Assurance Professional (CQAP).

  • Question 282:

    A CCA was part of an Assessment Team tasked with conducting a CMMC assessment for an OSC. Happy to have been part of the team that completed the assessment, the CCA posted the OSC's assessment results on their Twitter/X account. Which CMMC Code of Professional Conduct (CoPC) principle has the CCA violated?

    A. Availability
    B. Proper Use of Methods
    C. Confidentiality
    D. Objectivity

  • Question 283:

    An OSC uses a third party in all system repairs and has hired an MSP for penetration testing. The third party comes for either adaptive, preventative, perfective, or corrective system maintenance every three months, and the penetration tester does so continuously. Whenever the third party comes for maintenance, there's no documentation of the issues they tackled. On the other hand, the penetration tester delivers meticulously detailed documentation per their contract with the OSC. To comply with CMMC practice MA.L2- 3.7.1 ?Perform Maintenance, what should the OSC implement for the maintenance activities performed by the third-party vendor?

    A. Increase the frequency of maintenance activities to monthly intervals
    B. Perform all maintenance activities in-house without relying on a third-party vendor
    C. Require the third-party vendor to provide detailed maintenance logs and records
    D. Discontinue the use of the MSP for penetration testing

  • Question 284:

    An Assessment Team is reviewing the scope of a CMMC assessment for an OSC. The OSC has defined a narrow security boundary for their assessment, which the Assessment Team believes may not adequately protect all sensitive information. The OSC gives reasons for this, including financial constraints, and claims that CUI is only contained within an enclave defined by the boundary. However, after inspecting the facility and interviewing employees, you determine that some assets that may process CUI are outside the enclave. What is the risk of the OSC defining a security boundary that is too narrow in scope for the CMMC assessment?

    A. The OSC will have more systems that need to be managed separately.
    B. The OSC may not have done proper due diligence to protect all sensitive information within their environment.
    C. The assessment will be less expensive for the contractor.
    D. The assessment will take less time to complete.

  • Question 285:

    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 POAandM 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 POAandM Closeout Assessment. As the Lead Assessor, you and your assessment team review the OSC's updated POAandM, 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 POAandM review fail to result in a score of `MET,' what should the Lead Assessor recommend?

    A. Update the POAandM with the remaining practice deficiencies for the OSC to address.
    B. Recommend the OSC NOT be recommended for CMMC Level 2 Final Certification.
    C. Conduct a follow-up assessment to review the remaining practice deficiencies.
    D. Extend the timeframe for the OSC to address the remaining practice deficiencies.

  • Question 286:

    A contractor allows for the use of mobile devices in contract performance. Some employees access designs and specifications classified as CUI on such devices like tablets and smartphones. After assessing AC.L2-3.1.18 ?Mobile Device Connection, you find that the contractor maintains a meticulous record of mobile devices that connect to its information systems. AC.L2-3.1.19 ?Encrypt CUI on Mobile requires that the contractor implements measures to encrypt CUI on mobile devices and mobile computing platforms. The contractor uses device-based encryption where all the data on a mobile device is encrypted. Which of the following is a reason why would you recommend container-based over full-devicebased encryption?

    A. Container-based encryption offers granular control over sensitive data, improves device performance by encrypting selectively, and enhances security in Bring-Your-Own-Device (BYOD) environments
    B. Container-based encryption is more cost-effective
    C. It is more user-friendly and easier to deploy on a large scale
    D. Full-device encryption is not compatible with modern mobile operating systems

  • Question 287:

    A CMMC assessment for an OSC finds it has fully implemented 87 out of 110 practices. Unfortunately, the Assessment Team determines that the POAandM Closeout Assessment option cannot be used. Consequently, the OSC will not be recommended for certification. However, the OSC assessment official humbly requests the Lead Assessor to adjust the findings to allow for POAandM closeout and mark a five-point practice as implemented. How should the Lead Assessor respond?

    A. Politely decline the request and cite ethical reasons of violating the CoPC.
    B. Negotiate with the OSC to implement additional practices and reassess the POAandM Closeout Assessment option.
    C. Report the request to the Cyber AB and recommend disciplinary action against the OSC assessment official.
    D. Agree to the request and tweak the findings.

  • Question 288:

    A defense contractor retains your services to assess their information systems for CMMC compliance, particularly configuration management. The contractor uses CFEngine 3 for automated configuration and maintenance of its computer systems and networks. While chatting with the network's system admins, you realize they have deployed a modern compliance checking andmonitoring tool. However, when examining their configuration management policy, you notice the contractor uses different security configurations than those recommended by product vendors. The system administrator informs you they do this to meet the minimum configuration baselines required to achieve compliance and align with organizational policy. When examining the contractor's security configuration checklists, which of the following parameters are you not likely to find?

    A. The contractor's assessment readiness status
    B. File and directory permissions
    C. Protocol usage and application allowlisting
    D. Network configuration and port management

  • Question 289:

    When assessing an OSC's compliance with IR requirements, you realize they have deployed a system that tracks incidents, documents details, and updates the status throughout the incident response process. Personnel to whom incidents must be reported are identified and designated. While examining their documentation, you come across an incident response template that they use to capture all relevant information and ensure consistency in reporting to the identified authorities and organizational officials. Interviewing the IR team, you learn there is an escalation process that the contractor's cybersecurity team can use to address more serious incidents. From the scenario,the contractor has met all the required objectives for CMMC practice IR.L2-3.6.2 ?Incident Reporting, meaning its implementation of the said practice will be scored MET with a total of 5 points. For how long must the OSC retain the incident records?

    A. 72 hours
    B. 90 days
    C. 90 hours
    D. 72 days

  • Question 290:

    A contractor has retained you to assess compliance with CMMC practices as part of their triennial review. During your assessment of the AU domain, you discovered that the contractor has recently installed new nodes and servers on their network infrastructure. To assess their implementation of AU.L2-3.3.7 ?Authoritative Time Source, you trigger some events documented to meet AU.L2-3.3.1 ?System Auditing across both the new and existing systems, generating audit logs. Upon examining these logs, you notice inconsistencies in the timestamps between newly installed and previously existing nodes. Further investigation reveals that while the contractor has implemented a central Network Time Protocol (NTP) server as the authoritative time source, the new systems are configured to automatically adjust and synchronize their clocks only when the time difference with the NTP server exceeds 30 seconds. Based on this scenario, how many points would you score theOSC's implementation of CMMC practice AU.L2-3.3.7 ?Authoritative Time Source?

    A. 5
    B. -1
    C. 1
    D. -5
