The most effective way to prevent insecure code from reaching production is to integrate security gates directly into the CI/CD pipeline. Option A is correct because security gates involve automated scanning of dependencies, SBOM generation, code analysis, and policy enforcement during build and test phases. This ensures that vulnerabilities or policy violations are caught early in the development lifecycle.

Option B (load balancing) improves availability but is unrelated to code security. Option C (A/B testing) validates functionality, not security. Option D (caching strategies) affects performance, not code safety.

By embedding automated checks into CI/CD pipelines, teams adopt a shift-left security approach, ensuring compliance and minimizing risks of supply chain attacks. This practice directly supports platform engineering goals of combining security with speed and reducing developer friction through automation.

An API-driven approach in platform engineering enables developers to interact with the platform programmatically through self-service capabilities. Option C is correct because giving developers the ability to request and manage environments on demand via APIs or internal tooling exemplifies the API-first model. This approach abstracts infrastructure complexity, reduces manual intervention, and ensures automation and repeatability—all key goals of platform engineering.

Option A is a traditional request/response workflow but does not empower developers with real-time, self-service capabilities. Option B provides visibility but does not expose APIs for consumption or management. Option D focuses on automating platform updates rather than enabling developer interaction with platform services.

By exposing APIs for services such as provisioning environments, databases, or networking, the platform team empowers developers to operate independently while maintaining governance and consistency. This improves developer experience and accelerates delivery, aligning with internal developer platform (IDP) practices.

To achieve repeatability and consistency, CI pipelines must produce immutable artifacts that are uniquely identifiable and reproducible. Option D is correct because immutable artifacts (such as container images tagged with digests or versioned binaries) ensure that the same build artifact can be promoted across environments (dev, staging, production) without modification. This eliminates discrepancies caused by rebuilding code in different environments.

Option A (notifications) improves feedback but does not guarantee consistency. Option B (dynamic scaling) optimizes resource usage but does not address build reproducibility. Option C (dashboards) aid in visibility but are not critical to ensuring consistent outputs.

Immutable artifacts are essential for compliance, traceability, and reliability. They ensure that what has been tested is exactly what gets deployed, which is central to continuous delivery and GitOps practices.
