Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q76-Q81):

NEW QUESTION # 76
You are running a critical application that requires high availability and resilience. Which of the following Kubernetes storage solutions would best ensure data consistency and redundancy in case of pod failures?

  • A. Local Persistent Volumes
  • B. Distributed File Systems (e.g., GlusterFS, Ceph)
  • C. HostPath Volumes
  • D. Standard Persistent Disks
  • E. Ephemeral Storage

Answer: B

Explanation:
Distributed File Systems (e.g., GlusterFS, Ceph) provide high availability and data redundancy by replicating data across multiple nodes. This ensures data consistency and availability even if a pod or node fails. Local Persistent Volumes, Ephemeral Storage, and HostPath Volumes do not provide this level of data redundancy. Standard Persistent Disks offer persistence but not necessarily high availability and redundancy.


NEW QUESTION # 77
Consider a Kubernetes deployment where you have a microservice responsible for user authentication. You want to ensure that any communication to this service is encrypted and secure. What Kubernetes feature or open standard can help achieve this?

  • A. Open Policy Agent (OPA)
  • B. TLS/SSL
  • C. Pod Security Policies (PSPs)
  • D. Kubernetes RBAC
  • E. NetworkPolicy

Answer: B

Explanation:
TLS/SSL is a standard protocol for encrypting communication between applications. You can configure your authentication service and its clients to use TLS/SSL to ensure secure communication between them. While other options like PSPs, NetworkPolicy, and RBAC are related to security, they don't specifically address the encryption aspect of communication-


NEW QUESTION # 78
A new Pod is created. Then, the Pod is assigned to a Node. Which Kubernetes component was re-sponsible for determining which Node to assign the Pod to?

  • A. kubelet
  • B. Controller manager
  • C. Scheduler
  • D. API Server

Answer: C

Explanation:

NEW QUESTION # 79
Explain the difference between a Deployment and a StatefulSet in Kubernetes.

  • A. Deployments are used for managing the lifecycle of a single Pod, while StatefulSets manage multiple Pods.
  • B. Deployments handle rolling updates, while StatefulSets only support manual updates.
  • C. Deployments are used for deploying and managing stateless applications, while StatefulSets are used for deploying and managing stateful applications.
  • D. Deployments are used for stateless applications, while StatefulSets are used for stateful applications that require persistent storage and unique identities.
  • E. Deployments are responsible for scheduling Pods, while StatefulSets manage the lifecycle of Services.

Answer: C,D

Explanation:
Deployments are used for deploying and managing stateless applications, while StatefulSets are used for deploying and managing stateful applications. Deployments are ideal for applications where the state of each Pod is not important, while StatefulSets are designed for applications that require persistent storage, unique network identities, and ordered scaling.


NEW QUESTION # 80
Which kubernetes object do deployments use behind the scenes when they need to scale pods?

  • A. kubectl
  • B. Horizontal pod autoscaler
  • C. Replication controller
  • D. ReplicaSets

Answer: D
