Cyber AB Certified CMMC Assessor (CCA) Exam 認定 CMMC-CCA 試験問題 (Q88-Q93):質問 # 88
A company has a CUI enclave for handling all CUI processed, stored, and transmitted through the organization. While interviewing the IT manager, the CCA asks how assets that can, but are not intended to, handle CUI are identified. The IT manager refers to the CUI system's network diagram (which includes these assets) as well as the asset inventory (which lists these assets as Contractor Risk Managed Assets). Which other artifact MUST also mention these assets?
- A. The physical protection policy should list these assets as being part of the physical environment of the organization.
- B. The SSP should show these assets are managed using the company's risk-based security policies, procedures, and practices.
- C. The identification and authentication policy should show how these assets are identified.
- D. The awareness and training program should include these assets so they are covered for all employees.
正解:B
解説:
Contractor Risk Managed Assets (CRMA) are required to be identified in the System Security Plan (SSP) because the SSP must describe how each in-scope asset category is managed, including risk-based policies, procedures, and practices. Network diagrams and inventories alone are insufficient without documentation in the SSP.
Exact Extracts:
* CMMC Scoping Guide: "Contractor Risk Managed Assets are part of the CMMC Assessment Scope and must be identified in the OSC's SSP and supporting documentation."
* "The SSP must describe how the contractor manages risk for Contractor Risk Managed Assets."
* "The asset categories (CUI assets, Security Protection Assets, Contractor Risk Managed Assets, Specialized Assets) must be included in the SSP with supporting evidence." Why the other options are not correct:
* A: Identification/authentication policy does not specifically require mention of CRMAs.
* B: Physical protection policies address facility controls, not risk-managed assets.
* C: Awareness training covers employees, not technical classification of assets.
* D: Correct, because the SSP must explicitly document how CRMAs are managed using risk-based approaches.
References:
CMMC Assessment Scope - Level 2, Version 2.13: Asset categories and documentation requirements for CRMAs (pp. 6-10).

質問 # 89
A Lead Assessor is conducting an assessment for an OSC. The OSC is currently using doors and badge access to limit access to private areas of their campus to only authorized personnel. Which item is another means of controlling physical access to areas that contain CUI?
- A. Guards
- B. Firewalls
- C. Partition walls
- D. Cameras
正解:A
解説:
* Applicable Requirement: PE.L2-3.10.3 - "Control physical access to organizational systems, equipment, and the respective operating environments."
* Why A is Correct: Security guards are a recognized preventive and detective physical control to limit access to only authorized individuals. Guards can verify credentials, monitor behavior, and provide real-time deterrence.
* Why Other Options Are Insufficient:
* B (Cameras): Provide monitoring and evidence, but not direct access control.
* C (Firewalls): A network control, not a physical access measure.
* D (Partition walls): Barriers may help physically separate areas but do not control who enters.

質問 # 90
As a CCA, you are part of a team conducting a CMMC assessment of an OSC. The OSC provides you with evidence of the implementation of CMMC practices, including a proprietary compression algorithm. While chatting and drinking with your buddies at a bar, you observe another CCA who is also part of your team demonstrating how to use the compression algorithm. This CCA happens to be the Tech Lead of a renowned IT company. What guiding principle of the CMMC Code of Professional Conduct has the other CCA violated?
- A. Confidentiality
- B. Proper Use of Methods
- C. Availability
- D. Information Integrity
正解:A
解説:
Comprehensive and Detailed in Depth Explanation:
The CMMC Code of Professional Conduct (CoPC) mandates that CCAs maintain confidentiality of all customer data, including proprietary information like the OSC's compression algorithm, encountered during an assessment. Demonstrating this algorithm in a public setting, such as a bar, breaches this principle by disclosing sensitive OSC information without authorization. Option B (Information Integrity) relates to altering evidence, not disclosure. Option C (Availability) is not a CoPC principle. Option D (Proper Use of Methods) pertains to assessment techniques, not confidentiality. Option A is the clear violation here.
Extract from Official Document (CoPC):
* Paragraph 2.3 - Confidentiality (pg. 5):"When participating in a CMMC assessment, credentialed members of the Cyber AB should maintain confidentiality not only of government data but also of customer data."
* Paragraph 3.2(1) - Confidentiality Practices (pg. 6):"Protect confidential customer data from unauthorized disclosure unless permitted in writing by the Cyber AB or required by a legal obligation." References:
CMMC Code of Professional Conduct, Paragraphs 2.3 and 3.2(1).
質問 # 91
While assessing a company, the CCA is determining whether the company controls and manages connections between its corporate network and all external networks. The company has: (1) a strict employee policy prohibiting personal Internet use and personal email on company computers, and (2) firewalls plus a connection allow-list so only authorized external networks can connect to the company network. Are these safeguards sufficient to meet the applicable CMMC requirement?
- A. Yes. The company's strict employee policy is the best practice for meeting the requirement.
- B. No. The company needs full control over all external systems it interfaces with to meet the requirement.
- C. No. The company must isolate its system from all external connections to meet the requirement.
- D. Yes. The company's firewalls and connection allow-lists are appropriate technical controls to meet the requirement.
正解:D
解説:
* Applicable CMMC/NIST Requirement: AC.L2-3.1.20 - "Verify and control/limit connections to and use of external systems."
* Isolation Not Required (refutes B): The requirement acknowledges that individuals using external systems (e.g., contractors, partners) may need to access organizational systems. In such cases, organizations must ensure those connections do not compromise or harm organizational systems.
Therefore, complete isolation from all external systems is not mandated.
* Policy Alone is Insufficient (refutes A): Assessment guidance requires mechanisms that technically enforce terms and conditions for use of external systems. A written employee policy by itself does not satisfy the requirement unless paired with technical enforcement (e.g., firewalls, connection rules).
* Allow-lists & Firewalls are Best Practice (supports C): Assessment considerations specify that organizations should restrict external systems to an approved list, such as by using firewalls, VPNs, IP restrictions, or certificates. The company's use of firewalls and a connection allow-list directly addresses this requirement.
* Full Control of External Systems Not Required (refutes D): The definition of "external systems" clarifies that organizations typically do not have direct supervision or authority over those systems. The requirement is to limit and control connections to such systems, not to own or fully manage them.
* Assessment Objectives for AC.L2-3.1.20 (from NIST SP 800-171A):
* Connections to external systems are identified.
* Use of external systems is identified.
* Connections to external systems are verified.
* Use of external systems is verified.
* Connections to external systems are controlled/limited.
* Use of external systems is controlled/limited.
Firewalls and allow-lists satisfy these verification and limitation requirements, enabling a CCA to mark the practice MET if evidence is present.

質問 # 92
An OSC allows some employees to use their personal devices (laptops, tablets) for work purposes. The OSC enforces a Bring Your Own Device (BYOD) policy that requires employees to install Mobile Device Management (MDM) software on their devices. The MDM allows for remotewiping of lost or stolen devices and enforces access control policies. Employees use VPNs to remotely access the OSC network from their personal devices. What challenges might a CCA face when collecting evidence to assess the OSC's compliance with AC.L2-3.1.12 - Control Remote Access?
- A. The use of MDM software simplifies evidence collection on mobile device security configurations
- B. The CCA can rely solely on employee attestation to verify compliance with the BYOD policy
- C. The use of VPNs ensures a secure connection regardless of the device used for remote access
- D. Privacy concerns arise due to the personal nature of BYOD devices
正解:D
解説:
Comprehensive and Detailed in Depth Explanation:
AC.L2-3.1.12 requires OSCs to monitor and control remote access sessions, per NIST SP 800-171 and CMMC Level 2. In a BYOD environment with MDM and VPNs, the CCA must verify the effectiveness of these controls. However, the personal nature of employee devices introduces privacy concerns, limiting the CCA's ability to directly inspect configurations or logs without consent or legal constraints, as noted in the CAP. This complicates evidence collection compared to company-owned devices.
Option A (simplified evidence collection) overlooks privacy barriers. Option B (VPN security) assumes effectiveness without addressing verification challenges. Option D (employee attestation) is insufficient per CAP, which requires objective evidence. Option C correctly identifies privacy as a key challenge, making it the correct answer.
Reference Extract:
* CMMC Assessment Process (CAP) v1.0, Section 4.2:"BYOD environments may limit evidence collection due to privacy concerns associated with personal devices."
* NIST SP 800-171A, AC-3.1.12:"Assessors must verify control of remote access sessions, which may be hindered by device ownership."Resources:https://cyberab.org/Portals/0/Documents/Process-Documents
