Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Software Bill of Materials (SBOM) and dependency analysis
Software Bill of Materials (SBOM) is a list of all components in the application, including open-source libraries. Dependency analysis tools use SBOMs to identify known vulnerabilities. SAST analyzes source code, not libraries. DAST tests running applications. RASP provides runtime protection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Software Bill of Materials (SBOM) and dependency analysis
Why this is correct
SBOM lists all components, and dependency analysis checks them against known vulnerability databases.
- ✗
Runtime Application Self-Protection (RASP)
Why it's wrong here
RASP protects applications at runtime but does not identify library vulnerabilities pre-deployment.
- ✗
Static Application Security Testing (SAST)
Why it's wrong here
SAST analyzes source code for security flaws but does not focus on open-source library vulnerabilities.
- ✗
Dynamic Application Security Testing (DAST)
Why it's wrong here
DAST tests running applications from the outside; it does not analyze library dependencies.
