Q89. Have a pod ‘hello’ and a container in that pod ‘green’. Which of the following commands would get the logs for that container?

alias k=’kubectl’
k logs -p hello -c green

alias k=’kubectl’

alias k=’kubectl’
k get logs -p hello -c green

alias k=’kubectl’
k logs -p hello green

Q90. How can persistent volume be provisioned?

Automatically

Bootstrap

Dynamically

Q91. You are building a distributed system with microservices deployed in a Kubernetes cluster. Each microservice has its own database. How would you manage the consistency and reliability of data across these microservices?

Use a shared database for all microservices

Implement a distributed database system

Use a message broker to ensure data synchronization

Implement a distributed transaction manager

Use a combination of event sourcing and CQRS (Command Query Responsibility Segregation)

Q92. You are managing a large Kubernetes cluster with multiple namespaces. You want to control access to resources within different namespaces. Which of the following mechanisms can be used to achieve fine-grained access control?

Network policies

Role-Based Access Control (RBAC)

Pod Security Policies

Network Segmentation

Service Accounts

Q93. Which project is not a dominant CNCF project in the storage landscape?

Envoy

Vitess

Rook

TiKV

Q94. 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.

The pod will be automatically restarted.

The pod will be marked as “unhealthy”, but will continue to run.

The pod will be terminated and removed from the cluster.

The pod will be rescheduled to a different node in the cluster.

The pod will be automatically scaled down.

Q95. Fluentd is the only way to export logs from Kubernetes cluster or applications running in cluster

True

False

Q96. You are deploying a multi-container pod with each container requiring different resource limits. What Kubernetes resource allows you to define these individual limits?

ResourceQuota

LimitRange

PodSpec

ServiceAccount

Deployment

Q97. Which of the following command is used to get detailed information about the pod?

kubectl info

kubectl get

kubectl describe

kubectl explain

Q98. What do GitOps tools do in kubernetes?

They allow us to make changes to a kubernetes cluster using a Git repository

They manage the source code of kubernetes itself

They allow us to store software code in Git

They allows us to store container images in repositories

Q99. Which access control component of Kubernetes is responsible for authorization and decides what requestor is allowed to do?

Service Account

Role-based access control ‘RBAC’

Deployment

Q100. What standard does kubelet use to communicate with the container runtime?

Service Mesh Interface (SMI)

CRI-O

ContainerD

Container Runtime Interface (CRI)

Q101. You are monitoring a Kubernetes cluster using Prometheus. You notice a significant spike in CPUusage on a specific pod. To investigate further, you want to collect metrics related to individual processes running within that pod. Which Prometheus query can effectively achieve this?

Q102. Which of the following is an example of vertical scaling?

Using cluster autoscaler

Adding more resources (memory and/or cpu) to a kubernetes node

Adding more nodes to kubernetes cluster

Adding more replica pods to a deployment

Q103. You are configuring a Kubernetes cluster for a microservices-based application. Each microservice needs its own network namespace and isolated communication. Which Kubernetes networking feature would you use to achieve this?

Kubernetes Ingress

Kubernetes Service

NetworkPolicy

PodSecurityPolicy

Containerd

Q104. What is the purpose of a Kubernetes Ingress resource in the context of CI/CD and application deployment?

To define the desired number of replicas for a Deployment.

To manage the communication between pods within a deployment.

To provide a single entry point for external traffic to access services within the cluster.

To define the health checks for a Deployment.

To configure automated rollbacks during deployment failures.

Q105. Stateful set requires which service for the network identity of pods?

Ingress

Load Balancer Service

Headless Service

Q106. In Prometheus, what is the purpose of recording rules and how do they differ from alerting rules?

Recording rules create new time series based on existing metrics, while alerting rules trigger notifications based on metric conditions.

Recording rules define data aggregation and analysis, while alerting rules focus on time-series data visualization.

Recording rules are used for data storage optimization, while alerting rules are used for system performance monitoring.

Recording rules are primarily used for troubleshooting, while alerting rules are used for proactive issue detection.

Recording rules and alerting rules are interchangeable and can be used for similar purposes.

Q107. You have a Kubernetes cluster with a deployment of a stateless application. Explain how you would ensure high availability for the application even if a node fails. What are some essential configurations to implement for this purpose?

Configure the deployment with a high number of replicas and use a load balancer to distribute traffic.

Enable persistent volumes to store application data on a separate storage system.

Configure the deployment with a low number of replicas and use a service to expose the application.

Use a custom resource definition (CRD) to manage the high availability of the application.

Configure a pod disruption budget (PDB) to prevent a large number of pods from being deleted simultaneously.

Q108. What is the primary function of the Kubernetes control plane?

Schedules Pods to nodes based on resource availability and node affinity

Manages the lifecycle of Pods, ensuring that they are running as intended.

Provides a secure and reliable connection between the Kubernetes control plane and nodes.

Provides a central point of control and management for the Kubernetes cluster.

Enables communication between Pods and services within a Kubernetes cluster.
