200-901 Application Deployment and Security Practice Question
A CI/CD pipeline for a Python project should run unit tests and check for known vulnerabilities in dependencies. Which tool can be integrated into the pipeline to perform dependency scanning?
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
✓
Snyk
Snyk is a popular dependency scanning tool that integrates with CI/CD pipelines. pip audit and npm audit are similar but for specific ecosystems. Snyk supports multiple languages.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Docker
Why it's wrong here
Docker builds and runs containerised workloads; it provides no dependency vulnerability database or scanning engine. It would be correct for packaging the Python application into a reproducible image, not for checking libraries against CVE data.
- ✗
Kubernetes
Why it's wrong here
Kubernetes orchestrates containers; it runs workloads but performs no dependency vulnerability scanning. It is tempting because pipelines often deploy to Kubernetes, so it appears in the same toolchain. The scenario needs a scanner such as OWASP Dependency-Check or Snyk analysing Python package manifests.
- ✗
Jenkins
Why it's wrong here
Jenkins is a CI/CD automation server that orchestrates pipeline stages; it does not itself scan dependencies for known vulnerabilities. It would be correct for triggering builds and running unit tests, with a dedicated scanner invoked as a stage.
- ✓
Snyk
Why this is correct
Snyk scans third-party dependencies for known vulnerabilities, matching packages against a vulnerability database, which directly satisfies the pipeline's dependency-checking requirement. It integrates into CI/CD workflows and supports Python manifests such as requirements.txt and Pipfile, complementing the unit tests rather than replacing them.
