Question 1

Which of the following is a primary benefit of using Kubernetes Custom Resource Definitions (CRDs) in a self-service platform model?

Options :

A : CRDs automatically manage the scaling and failover of platform services without additional configuration.

B : CRDs eliminate the need for Role-based access control (RBAC) configurations in Kubernetes clusters.

C : CRDs enable platform teams to define custom APIs without modifying the Kubernetes API server code.

D : CRDs provide built-in support for multi-cloud deployments without additional tooling.

Answer: C

Question 2

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

Options :

A : Isolates different stages of application development and deployment

B : Reduces cloud costs by running applications in different locations.

C : Increases application performance by distributing traffic.

D : Ensures all applications use the same infrastructure.

Answer: A

Question 3

In a CI/CD pipeline, why is a build artifact (e.g., a Docker image) pushed to an OCI-compliant registry?

Options :

A : To store the image in a central registry so deployment environments can pull it for release.

B : To allow the container image to be analyzed and transformed back into source code.

C : To publish versioned artifacts that can be tracked and used to inform users of new releases.

D : To enable the registry service to execute automated tests on the uploaded container image.

Answer: A

Question 4

A company is implementing a service mesh for secure service-to-service communication in their cloud native environment. What is the primary benefit of using mutual TLS (mTLS) within this context?

Options :

A : Allows services to authenticate each other and secure data in transit.

B : Allows services to bypass security checks for better performance.

C : Enables logging of all service communications for audit purposes.

D : Simplifies the deployment of microservices by automatically scaling them.

Answer: A

Question 5

In what way does an internal platform impact developers' cognitive load?

Options :

A : It has no impact on the mental effort required from developers, ensuring their cognitive load remains unchanged.

B : It reduces cognitive load by hiding complex infrastructure details and providing simple interfaces.

C : It shifts all operational complexity onto developers, making them fully responsible for managing the process.

D : It increases cognitive load by requiring knowledge of all the underlying tools involved.

Answer: B
