200-901 Implementing a secure CI/CD pipeline Practice Question
A company is implementing a secure CI/CD pipeline. Which THREE practices are essential for securing the pipeline?
⚠ Common exam trap
Cisco often tests the misconception that 'allowing any public registry' is acceptable for speed or convenience, but the correct practice is to restrict registries to trusted, scanned sources to prevent supply chain attacks.
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
✓
Sign and verify all build artifacts.
Signing and verifying build artifacts ensures integrity and authenticity, preventing tampered artifacts from being deployed. This is a core supply chain security practice, often implemented using tools like GPG or Sigstore (Cosign) to generate and validate cryptographic signatures. Without verification, an attacker could inject malicious code into the pipeline by replacing a signed artifact with a compromised one.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Sign and verify all build artifacts.
Why this is correct
Signing ensures artifacts are not tampered with.
- ✗
Allow all container images to be pulled from any public registry.
Why it's wrong here
This introduces risk of malicious images; use a curated registry.
- ✗
Store secrets (API keys, passwords) in version control.
Why it's wrong here
Secrets should never be in version control; use secret management tools.
- ✓
Implement role-based access control (RBAC) on the CI/CD system.
Why this is correct
RBAC limits access to pipeline resources.
- ✓
Use static application security testing (SAST) tools in the build stage.
Why this is correct
SAST helps find vulnerabilities early in development.
