CMMC-CCA Exam Dumps : Certified CMMC Assessor (CCA) Exam

Malicious code protection is typically implemented and managed by system or network administrators, who configure, deploy, and monitor anti-malware solutions. Interviews with these administrators provide direct evidence of control implementation.

Exact Extracts:

SI.L2-3.14.2: “Provide protection from malicious code at appropriate locations within organizational information systems.”

CMMC Assessment Guide: “Interviews should be conducted with administrators responsible for deployment and monitoring of malicious code protection.”

NIST SP 800-171A (SI.L2-3.14.2): “Interview system or network administrators to determine how malicious code protection is implemented.”

Why other options are not correct:

A (developers): Developers do not typically manage system-wide malicious code protections.

C (audit personnel): They review logs, not deploy/manage protections.

D (security advisory staff): They track alerts but don’t operate malicious code defenses.

Applicable Requirement: SC.L2-3.13.16 — “Protect the confidentiality of CUI at rest.”

Why D is Correct: Cryptographic mechanisms (e.g., full-disk encryption, database encryption, file encryption) provide the strongest protection for information at rest by preventing unauthorized disclosure if systems or media are accessed.

Why Other Options Are Insufficient:

A (Patching): Protects against vulnerabilities, but not specific to data-at-rest confidentiality.

B (File share): Provides a storage method, not protection.

C (Secure offline storage): Helps physically, but not sufficient for digital confidentiality without encryption.

CMMC Assessment Guide – Level 2, Data at Rest Protection

===========

CMMC scoping focuses on assets that process, store, transmit, or protect CUI. A smoke detector connected to the OSC network is an IoT device with no impact on CUI, so it is considered Out-of-Scope. The other items (data centers used by the OSC, MSP SIEM tools, and MSP offices handling OSC management) all directly affect the OSC’s CUI environment and therefore fall within scope.

Exact extracts:

“CUI Assets are those that process, store, or transmit CUI.”

“Security Protection Assets are those that provide security functions for CUI Assets.”

“External Service Providers (e.g., MSPs, data centers, SIEMs) that support CUI Assets are in-scope.”

“Assets that cannot affect the confidentiality of CUI (e.g., unrelated IoT devices) are considered Out-of-Scope.”

Expanded explanation:

Data centers (A): If OSC CUI is stored or processed there, they are in-scope.

SIEM tools (C): Provide security monitoring of OSC networks — a clear Security Protection Asset.

MSP office (D): MSPs providing services that affect CUI are in-scope, including their management locations.

Smoke detector (B): Despite being network-connected, it does not interact with CUI or provide protective functions; it is explicitly out-of-scope.

Why the other options are in scope:

They either process, protect, or manage CUI directly.

Excluding them would improperly narrow the assessment boundary.
