Question 16

To simplify service consumption for development teams on a Kubernetes platform, which approach combines service discovery with an abstraction of underlying infrastructure details?

Correct Answer: D
Simplifying developer access to platform services is a central goal of internal developer platforms (IDPs).
Option D is correct because a service catalog with abstracted APIs and automated registration provides a unified interface for developers to consume services without dealing with low-level infrastructure details. This approach combines service discovery with abstraction, offering golden paths and self-service capabilities.
Option A burdens developers with hardcoded dependencies, reducing flexibility and portability. Option B relies on manual documentation, which is error-prone and not dynamic. Option C increases cognitive load by requiring developers to interact directly with Kubernetes APIs, which goes against platform engineering's goal of reducing complexity.
A service catalog enables developers to provision databases, messaging queues, or APIs with minimal input, while the platform automates backend provisioning and wiring. It also improves consistency, compliance, and observability by embedding platform-wide policies into the service provisioning workflows. This results in a seamless developer experience that accelerates delivery while maintaining governance.

Question 17

Which approach is an effective method for securing secrets in CI/CD pipelines?

Correct Answer: B
The most secure and scalable method for handling secrets in CI/CD pipelines is to use a secrets manager with encryption. Option B is correct because solutions like HashiCorp Vault, AWS Secrets Manager, or Kubernetes Secrets (backed by KMS) securely store, encrypt, and control access to sensitive values such as API keys, tokens, or credentials.
Option A (restricted config files) may protect secrets but lacks auditability and rotation capabilities. Option C (plain-text environment variables) exposes secrets to accidental leaks through logs or misconfigurations.
Option D (base64 encoding) is insecure because base64 is an encoding, not encryption, and secrets can be trivially decoded.
Using a secrets manager ensures secure retrieval, audit trails, access policies, and secret rotation. This aligns with supply chain security and zero-trust practices, reducing risks of credential leakage in CI/CD pipelines.

Question 18

As a Cloud Native Platform Associate, you are tasked with improving software delivery efficiency using DORA metrics. Which of the following metrics best indicates the effectiveness of your platform initiatives?

Correct Answer: A
Lead Time for Changes is the DORA metric that best measures the efficiency and impact of platform initiatives. Option A is correct because it tracks the time from code commit to successful production deployment, directly reflecting how effectively a platform enables developers to deliver software.
Option B (MTTR) measures resilience and recovery speed, not efficiency. Option C (Change Failure Rate) measures deployment stability, while Option D (SLAs) are contractual agreements, not engineering performance metrics.
By reducing lead time, platform engineering demonstrates its ability to provide self-service, automation, and streamlined CI/CD workflows. This makes Lead Time for Changes a critical measurement of platform efficiency and developer experience improvements.

Question 19

What is the primary purpose of using multiple environments (e.g., development, staging, production) in a cloud native platform?

Correct Answer: A
The primary reason for implementing multiple environments in cloud native platforms is to isolate the different phases of the software development lifecycle. Option A is correct because environments such as development, staging, and production enable testing and validation at each stage without impacting end users. Development environments allow rapid iteration, staging environments simulate production for integration and performance testing, and production environments serve real users.
Option B (reducing costs) may be a side effect but is not the main purpose. Option C (distributing traffic) relates more to load balancing and high availability, not environment separation. Option D is the opposite of the goal-different environments often require tailored infrastructure to meet their distinct purposes.
Isolation through multiple environments is fundamental to reducing risk, supporting continuous delivery, and ensuring stability. This practice also allows for compliance checks, automated testing, and user acceptance validation before changes reach production.

Question 20

In a GitOps setup, which of the following correctly describes the interaction between components when using a pull-based approach?

Correct Answer: A
GitOps uses a pull-based approach, where controllers inside the cluster continuously reconcile the desired state stored in Git with the actual cluster state. Option A is correct because GitOps sync agents (e.g., Argo CD, Flux) poll or watch Git repositories for changes and automatically apply updates to the cluster.
Option B reverses the model-clusters do not send updates to Git; Git is the source of truth. Option C is partially misleading: webhooks can trigger faster syncs but reconciliation is still pull-based. Option D misrepresents GitOps-Git never pushes directly to clusters.
This pull-based approach ensures greater security (clusters pull changes rather than exposing themselves to pushes), consistency (Git as source of truth), and continuous reconciliation (drift correction).
