Prepare for the CMMC-CCA Certified CMMC Assessor (CCA) exam with CertQueen's independently developed study resources. Review important concepts, practice scenario-based questions, and use clear explanations to identify areas that require further study.

Question#1

Understanding that changes are critical in any production environment, a DoD contractor has instituted measures to manage them. All software changes can only be implemented by defined individuals. These changes must go through a rigorous change approval process and must be implemented from a secure server located in the company's headquarters.
The personnel affecting the changes access the server room using access cards and an iris scan. To log into the server, they must enter their passwords to receive a one-time password (OTP), which must be keyed in within 2 minutes. After any changes are made, the chairperson of the contractor's Change Review Board and the CISO get a notification to approve the changes before they take effect.
Based on the contractor's current implementation how would you score their effort to address CM.L2-3.4.5-Access Restrictions for Change?

A. Met (+5 points)
B. Met (+3 points)
C. Met (+1 point)
D. Not Met (-5 points)

Explanation:
From the scenario, the contractor has implemented measures to define, document, approve, and enforce physical and logical access restrictions associated with changes to their systems. Since the contractor has implemented controls to meet all the requirements of CM.L2-3.4.5-Access Restrictions for Change, their implementation of this practice would be scored as "Met (5 points)," indicating full compliance with the practice.

Question#2

A contractor plans to bid for a DoD contract and has installed new network file servers to separate their commercial and DoD work. When examining the server documentation, you realize the server has some open ports. Upon further testing, you know the server has some default features that are not essential for file storage or transfer.
The server has a default remote desktop functionality that allows users remote access to the server's desktop environment. Files are transferred by default using FTP which is less secure than Server Message Block (SMB) protocol. However, the contractor's operations do not require remote access capabilities.
Although the roles of each system are defined in their configuration management policy, a user can install any application or service they need. After some interviews, you learn this ensures every employee is comfortable using a system or software they are most conversant with, despite having defined services or software for specific functions.
From this scenario, how has the contractor failed to meet the requirements of CM.L2.3.4.6-Least Functionality?

A. Failing to close unnecessary ports and turn off remote desktop functionality.
B. Separating commercial and DoD work on different servers.
C. Failing to train employees on the importance of system hardening.
D. Not having a well-defined configuration management policy.

Explanation:
Allowing users to install any application or service they need despite having defined services or software for specific functions goes against the principle of configuring systems to provide only essential capabilities. Failure to close unnecessary ports and turn off the default remote desktop functionality on the file server, which is unnecessary for its intended purpose of file storage and transfer, also contradicts the practice. Additionally, by allowing unrestricted software installation and failing to disable unnecessary ports/functionality, the contractor has not met the requirements of CMMC practice CM.L2-3.4.6-Least Functionality: "Employ the principle of least functionality by configuring organizational systems to provide only essential capabilities."

Question#3

A remote access session must be secured using FIPS-validated cryptography to provide confidentiality and prevent anyone from deciphering session information.
To demonstrate compliance with AC.L2-3.1.13-Remote Access Confidentiality, what can't the contractor provide as evidence?

A. Specification of the FIPS-validated cryptographic modules and algorithms used, including their references.
B. Evidence of FIPS validation, such as validation certificates or references to validated modules from the Cryptographic Module Validation Program (CMVP).
C. Configuration files, settings, and scripts used to implement and enforce the use of FIPS-validated cryptography for remote access sessions.
D. Remote access routing protocols

Explanation:
To demonstrate they have used a FIPS 140-2 or -3 validated cryptographic module, the contractor must cite as evidence specifications of the cryptographic algorithms and modules, validation certificates, documented guidelines and requirements for the selection, implementation, and configuration of FIPS-validated cryptographic modules and algorithms, etc.

Question#4

After numerous discussions and iterations, the OSC and Lead Assessor have finalized the Pre-Assessment Plan, which outlines the key details of how the assessment will be conducted, including the scope, timeline, resource requirements, and other logistical considerations.
What is the final step before commencing a CMMC assessment?

A. Creating a new data upload in CMMC eMASS
B. Uploading the Pre-Assessment Data Form into CMMC eMASS
C. Obtaining approval from the Lead Assessor
D. Reviewing the Pre-Assessment Data Form

Explanation:
After the OSC and Lead Assessor agree on the content and submit the final Pre-Assessment Plan, it is uploaded into CMMC eMASS at the completion of Phase 1. This must be done before the assessment commences.

Question#5

An OSC and a C3PAO Assessment Team are in the early stages of preparing for their CMMC assessment. During the process of confirming the corporate identity for the assessment, the Assessment Team discovers the OSC does not have a valid Commercial and Government Entity (CAGE) code issued by the Department of Defense. The team is now considering the implications of this finding and the next steps they should take.
When confirming the corporate identity to be assessed, what can happen if you determine the HQ organization doesn't have a valid CAGE code?

A. You would help the OSC register and obtain a CAGE code from the Do
B. You would request a waiver from the Do
C. You would continue with the assessment as planned.
D. The assessment cannot continue.

Explanation:
If you determine the HQ organization does not have a valid CAGE code during the process of confirming the corporate identity for an assessment, the assessment cannot continue. A CAGE code is a unique five-character ID assigned by the DoD to its suppliers and corporations. It is a mandatory requirement for companies to have a valid CAGE code to do business with the U.S. federal government or receive federal contracts and awards. Without a valid CAGE code, the organization lacks proper identification and registration with the government contracting system. This would prevent the assessment from proceeding further, as the corporate identity cannot be established and verified per regulations.
