Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q107-Q112):

NEW QUESTION # 107
You are developing a microservices application with multiple pods communicating over a shared network. You need to implement a mechanism that ensures only authorized pods can access specific services within the network. What Kubernetes feature can help achieve this?

  • A. NetworkPolicy
  • B. ResourceQuota
  • C. PodSecurityPolicy
  • D. LimitRange
  • E. ServiceAccount

Answer: A

Explanation:
NetworkPolicy is designed for network traffic control within a Kubernetes cluster It allows you to define rules that control inbound and outbound traffic for pods based on their labels, namespaces, and other criteria. This enables you to enforce access restrictions between pods and services within your application's network. PodSecurityPolicy primarily restricts security settings for pods. ServiceAccount provides identity and credentials, and ResourceQuota and LimitRange manage resource usage.


NEW QUESTION # 108
Consider a pod with a "readinessProbe" that checks for a specific file existence. Explain what happens if the probe fails repeatedly, and how it affects the pod's lifecycle.

  • A. The pod will be automatically scaled down.
  • B. The pod will be automatically restarted.
  • C. The pod will be terminated and removed from the cluster.
  • D. The pod will be rescheduled to a different node in the cluster.
  • E. The pod will be marked as "unhealthy", but will continue to run.

Answer: E

Explanation:
If the "readinessProbe" fails repeatedly, the pod will be marked as "unhealthy", but it will continue to run. The "readinessProbe" is responsible for ensuring that the pod is ready to receive traffic. If the probe fails, it indicates that the pod is not yet ready, and Kubernetes will not direct traffic to it. The pod will not be restarted, terminated, rescheduled, or scaled down. It will remain in an unhealthy state, and traffic will only be directed to it once the probe starts succeeding. This allows the pod to continue running while it resolves the issue causing the probe failures.


NEW QUESTION # 109
You're building a new cloud-native application using gRPC for communication between microservices. You want to use Jaeger for distributed tracing to track the flow of requests through your microservices. What should you do to integrate Jaeger with your gRPC application?

  • A. Use a dedicated tracing proxy that sits between your gRPC services and intercepts traffic to send tracing data to Jaeger.
  • B. Configure Istio to automatically inject tracing into gRPC calls and send the data to Jaeger.
  • C. Modify your gRPC client and server code to explicitly log trace information using Jaeger's logging libraries.
  • D. Use Jaeger's built-in support for gRPC tracing, which automatically intercepts gRPC calls and sends data to Jaeger.
  • E. Configure a custom gRPC interceptor to intercept gRPC calls and emit tracing data to Jaeger.

Answer: B,D

Explanation:
The correct answers are B and D . Jaeger provides built-in support for tracing gRPC applications, and Istio can also be used to automatically inject tracing into gRPC calls. B: Use Jaeger's built-in support for gRPC tracing, which automatically intercepts gRPC calls and sends data to Jaeger. Jaeger offers libraries and integration points for popular frameworks like gRPC. Using Jaeger's gRPC tracing capabilities, you can automatically instrument your gRPC applications and capture tracing data without needing to manually modify your code extensively. D: Configure Istio to automatically inject tracing into gRPC calls and send the data to Jaeger. Istio, a service mesh, offers automatic tracing capabilities for gRPC applications. By configuring Istio, you can enable tracing for gRPC calls and send tracing data to Jae er streamlinin the tracin rocess and reducin code modifications within our services. The other options are incorrect or less efficient: A: Configure a custom gRPC interceptor to intercept gRPC calls and emit tracing data to Jaeger. While you can create a custom interceptor, Jaeger's built-in support and Istio's automatic tracing mechanisms are more convenient and often preferred for gRPC tracing. C: Modify your gRPC client and server code to explicitly log trace information using Jaeger's logging libraries. Manual code modifications are less efficient compared to using Jaeger's built-in support or Istio's automatic tracing. E: Use a dedicated tracing proxy that sits between your gRPC services and intercepts traffic to send tracing data to Jaeger. While a tracing proxy could work, it adds an extra layer of complexity and potential performance overhead compared to built-in support or Istio's integration.


NEW QUESTION # 110
Which of the following is NOT a key characteristic of a serverless architecture?

  • A. Automatic scaling based on workload demand
  • B. Pay-per-use pricing model.
  • C. Focus on business logic rather than infrastructure management
  • D. Pre-provisioned and managed servers-
  • E. Event-driven execution model.

Answer: D

Explanation:
Serverless architectures are designed to abstract away the need for managing servers. They rely on cloud providers to handle provisioning, scaling, and infrastructure maintenance. Option C, Pre-provisioned and managed servers, contradicts the core principle of serverless computing, which is to avoid managing server infrastructure.


NEW QUESTION # 111
You are implementing a GitOps workflow for your Kubernetes cluster. Which of the following best practices should you consider?

  • A. IJse Git tags to mark specific releases of your Kubernetes configurations.
  • B. Store all your Kubernetes configurations in a single Git repository, regardless of their purpose or scope.
  • C. Ensure that all changes to your Kubernetes configurations are reviewed and approved before being deployed.
  • D. IJse a separate Git repository for each Kubernetes resource, such as deployments, services, and ingress.
  • E. Organize your Git repository with a clear directory structure for different namespaces and applications.

Answer: A,C,E

Explanation:
Option C promotes organization and maintainability by structuring your repository, while option D enables tracking specific releases through Git tags. Option E emphasizes the importance of code reviews and approvals to ensure the integrity of your deployments. These practices collectively contribute to a robust and well-managed GitOps workflow.
