You are a CCA working for a C3PAO that has entered into a contractual agreement to provide CMMC assessment services for an OSC. After validating the evidence, the C3PAO feels that thetask is beyond its capabilities and informs the OSC that it cannot continue with the assessment. The C3PAO cites "insufficient workforce" as the reason. What principle of the CMMC CoPC has the C3PAO broken?
A. Adherence to Materials and MethodsA Defense Contractor is preparing for their upcoming CMMC Level 2 assessment. One of the key controls they need to address is CMMC practice MP.L2-3.8.5 ?Media Accountability, which deals with maintaining accountability for media containing CUI during transport outside of controlled areas. The organization regularly needs to transport physical media, such as hard drives and backup tapes, between their primary data center and an off-site storage facility. In the past, they have simply used standard packaging and commercial shipping services to move this media. Which of the following best describes a control that maintains accountability for media containing CUI during transport outside of controlled areas?
A. Using tamper-proof packaging and a reputable shipping service with trackingYou are assessing a contractor that develops software for air traffic control systems. In reviewing their documentation, you find that a single engineer is responsible for designing new ATC system features, coding the software updates, testing the changes on the development network, and deploying the updates to the production ATC system for customer delivery. How will proper separation of duties help the contractor meet the intent of AC.L2-3.1.4 ?Separation of Duties?
A. It allows the engineers to specialize in specific areasAn OSC plans to undergo a CMMC Level 2 assessment with your C3PAO firm. As the Lead Assessor, you are collaborating with the OSC to develop the evidence collection approach for Phase 1. The OSC proposes conducting most interviews virtually due to geographically dispersed employees. You are responsible for defining the evidence collection methods for artifacts, interviews, tests or demonstrations, and information requests. Additionally, you must determine how virtual data collection will be managed, including security protocols for CUI and FCI. Which of the following is the most appropriate approach for artifact collection in this scenario?
A. Use a combination of virtual document sharing and a limited on-site visit.During a CMMC assessment, you review the OSC's documented procedures for access control.These procedures detail a user access request and approval process for the organization's Human Resources (HR) information system. You then interview IT personnel responsible for access control, who confirm the documented procedures accurately reflect how access is managed for the HR system. However, the OSC's network diagram reveals the presence of other in-scope systems critical to their operations, such as their Engineering Design Database and Manufacturing Control System. Neither the documented procedures nor the interview addressed access control practices for these additional systems. Based on the CMMC Assessment Process guidelines on evidence sufficiency, how would you characterize the evidence collected so far regarding access control?
A. Valid but incompleteAfter you ask to examine some audit records, the contractor's system administrator informs you that there is a process to follow before accessing them. The logs are hashed using SHA-512 algorithms, and the system administrator has to run an algorithm to recalculate the hashes for the audit records to verify their integrity before running a decryption algorithm to decrypt the data. Since this might take some time, you tour the facility while interviewing personnel with audit and accountability roles. You see an employee holding the door for another without using their physical access card. While interviewing the contractor's employees, you find that they can access all audit logging tools and tweak the settings according to their needs or requirements. Upon examining the contractor's access control policy, you realize they have not defined the measures to protect audit logging tools. Which of the following statements accurately describes the contractor's compliance with protecting audit logging tools from unauthorized access, modification, and deletion, as required by AU.L2-3.3.8 ?Audit Protection?
A. The contractor's compliance cannot be determined based on the information providedDuring a CMMC Level 2 assessment, the OSC's Assessment Official asks the Lead Assessor if they can exclude a small subsidiary from the assessment scope because it only handles a minimal amount of CUI. The subsidiary's systems are networked with the main OSC environment. What should the Lead Assessor do?
A. Agree to exclude the subsidiary since it handles minimal CUI.Mobile devices are increasingly becoming important in many contractors' day-to-day activities. Thus, the contractors must institute measures to ensure they are correctly identified and any connections are authorized, monitored, and logged, especially if the devices or their connections process, store, or transmit CUI. You have been hired to assess a contractor's implementation of CMMC practices, one of which is AC.L2-3.1.18. Mobile Device Connections. To successfully test the access control capabilities authorizing mobile device connections to organizational systems, you must first identify what a mobile device is. Mobile devices connecting to organizational systems must have a device-specific identifier. Which of the following is the main consideration for a contractor when choosing an identifier?
A. Choosing an identifier that can accommodate all devices and be used consistently within the organizationAn OSC uses a web application for document management. Employees can access this application from any internet-connected device through a web browser. The application resides on servers in a secure data center managed by a third-party vendor. The OSC maintains separate servers within its network to store the documents. When employees use the web application to upload documents, what type of locations are they interacting with?
A. A logical location for the web application and a physical location for the document storage serversYou 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 assessment, you find that the OSC has failed to meet the requirements for CMMC practice AU.L2-3.3.4 ?Audit Failure Alerting. According to the CMMC Assessment Process (CAP), which of the following should be your next step?
A. Immediately stop the assessment and report the failure to the C3PAO.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
