This CS0-003 practice question tests your understanding of vulnerability management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: sCA identifies known vulnerabilities in third-party and open-source components.. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A development team wants to find vulnerable open-source libraries before deployment. Which control best fits this stage? For validation, Which action should be taken before closing or downgrading the finding?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Wireless spectrum analysis
Why wrong: Spectrum analysis is unrelated to application dependencies.
Database transaction log backups
Why wrong: Backups do not identify vulnerable libraries.
Software composition analysis in the CI/CD pipeline
SCA identifies vulnerable third-party dependencies and can gate builds before release.
Physical badge access reviews
Why wrong: Badge reviews do not assess software components.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Software composition analysis in the CI/CD pipeline
Software composition analysis (SCA) is the correct control because it specifically scans open-source libraries and their dependencies for known vulnerabilities (CVEs) and license compliance issues. Integrating SCA into the CI/CD pipeline ensures that vulnerable libraries are identified automatically before the code is deployed, aligning with the shift-left security principle.
Key principle: SCA identifies known vulnerabilities in third-party and open-source components.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Wireless spectrum analysis
Why it's wrong here
Spectrum analysis is unrelated to application dependencies.
Database transaction log backups
Why it's wrong here
Backups do not identify vulnerable libraries.
Software composition analysis in the CI/CD pipeline
Why this is correct
SCA identifies vulnerable third-party dependencies and can gate builds before release.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept

Physical badge access reviews
Why it's wrong here
Badge reviews do not assess software components.
Common exam traps
Cisco often tests the distinction between vulnerability identification (SCA) and operational controls (backups, spectrum analysis), leading candidates to confuse general security practices with the specific need for open-source library scanning.
Detailed technical explanation
SCA tools work by generating a Software Bill of Materials (SBOM) from package manager manifests (e.g., pom.xml, package.json) and cross-referencing each component against databases like the National Vulnerability Database (NVD) or GitHub Advisory Database. A real-world scenario is the Log4Shell vulnerability (CVE-2021-44228), where SCA in the pipeline would have flagged the vulnerable Log4j version before deployment, preventing exploitation.
Key takeaway
SCA identifies known vulnerabilities in third-party and open-source components.
Real-world example
A security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
