Free Cyber AB CMMC-CCA Exam Questions

While examining a contractor's audit and accountability policy, you realize they have documented types of events to be logged and defined content of audit records needed to support monitoring, analysis, investigation, and reporting of unlawful or unauthorized system activities. After the logs are analyzed, the results are fed into a system that automatically generates audit records stored for 30 days. However, mechanisms implementing system audit logging are lacking after several tests because they produce audit logs that are too limited. You find that generated logs cannot be independently used to identify the event they resulted from because the defined content specified therein is too limited. Additionally, you realize the logs are retained for 24 hours before they are automatically deleted. When assessing the contractor's information systems, how would you mark their implementation of AU.L2-3.3.1-System Auditing? 

While assessing an OSC, you realize they have given identifiers to systems, users, and processes. Examining their documentation, you know they have assigned accounts uniquely to employees, contractors, and subcontractors. The OSC has an automated system that disables any identifiers that are left unused for 6 months. You also learn from interviewing IT security administrators that the OSC has a defined a technical and documented policy where identifiers can only be reused after 12 months. How is the OSC likely to consider CMMC practice IA.L2-3.5.5-Identifier Reuse if you find issues with its implementation?

Tina is working on a team conducting a Level 2 assessment for Humvees-R-Us (HRU). While gathering evidence, Tina notices that HRU has not updated several critical policies in years. Knowing that HRU is investing a significant amount of money in the assessment, she tells Bob, the CEO of HRU, that she will date the policies to make them appear as if they have been regularly revised. She explains that this will help HRU pass their assessment and save them the cost of a reassessment. Tina believes changing the dates isn’t a big deal since HRU has policies written but has not revised them as frequently as required.Was it right for Tina to adjust the dates during the assessment? If not, which principle of the CMMC Code of Professional Conduct did she violate?

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 time stamps 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 the OSC's implementation of CMMC practice AU.L2-3.3.7-Authoritative Time Source?
