Kubernetes and Container Orchestration Essentials

1. What does a PersistentVolume (PV) provide in Kubernetes?

Temporary storage for Pod logs

Cluster-level storage resource abstracted from infrastructure

Network bandwidth allocation

CPU resource limits

2. In cloud deployments, container orchestration improves resource efficiency by____.

Automatically allocating CPU and memory to Pods based on demand

Eliminating the need for monitoring tools

Removing all security requirements

Preventing any container failures

3. What is the advantage of using StatefulSets over Deployments in Kubernetes?

StatefulSets maintain stable Pod identities and persistent storage

StatefulSets are faster for scaling applications

StatefulSets eliminate the need for Services

StatefulSets automatically update container images

4. How do container registries support cloud deployments?

They store and distribute container images across environments

They manage Kubernetes cluster certificates

They handle user authentication only

They monitor Pod performance metrics

5. What is a DaemonSet in Kubernetes?

A Deployment that runs a single Pod replica

A resource ensuring a Pod runs on every node in the cluster

A scheduled job that runs periodically

A service that manages external load balancers

6. In container orchestration, what does 'desired state' mean?

The configuration users want the system to maintain automatically

The current running state of containers

The maximum resource allocation allowed

The backup state of all data

7. What is the function of an Ingress resource in Kubernetes?

To manage internal Pod communication

To provide external HTTP/HTTPS access to cluster services

To store encrypted secrets

To schedule batch jobs

8. Which cloud platforms offer managed Kubernetes services?

AWS EKS, Azure AKS, Google GKE only

Only on-premises installations

AWS EKS, Azure AKS, Google GKE, and others

No cloud providers support Kubernetes

9. What does RBAC (Role-Based Access Control) manage in Kubernetes?

Container image versioning

User and service account permissions within the cluster

Network traffic routing between Pods

Database replication settings

10. In Kubernetes, what is the purpose of a Liveness Probe?

To verify if a container is running and restart it if unhealthy

To measure network latency between nodes

To limit resource consumption

To authenticate users accessing the cluster

11. What is the primary purpose of container orchestration in cloud environments?

To automate deployment, scaling, and management of containerized applications

To replace traditional virtual machines entirely

To increase storage capacity of cloud servers

To simplify user authentication protocols

12. How does Kubernetes handle automatic scaling of Pods?

Through the Horizontal Pod Autoscaler based on metrics

By manually editing Deployment replicas

Using fixed Pod counts set at deployment time

Through external cloud provider APIs only

13. What is a Namespace in Kubernetes used for?

To isolate and organize resources within a cluster

To encrypt sensitive data in etcd

To define external IP addresses

To manage container image registries

14. Which Kubernetes resource allows you to manage configuration data separately from application code?

Secret

ConfigMap

Namespace

Role

15. In Kubernetes, what does the kube-scheduler do?

Assigns Pods to nodes based on resource requirements and constraints

Deletes unused Pods automatically

Manages all external API requests

Configures network policies for Pods

16. What is the role of etcd in a Kubernetes cluster?

It runs containerized applications on worker nodes

It stores all cluster configuration and state data

It manages external load balancers

It schedules Pods across available nodes

17. Which Kubernetes object defines desired state for Pods and includes replica count?

ConfigMap

Deployment

Ingress

PersistentVolume

18. What is the function of a Kubernetes Service?

To expose Pods to network traffic and enable load balancing

To store persistent data in the cluster

To manage user access and authentication

To monitor CPU usage across nodes

19. In Kubernetes, a Pod is the smallest deployable unit. What does a Pod typically contain?

Multiple virtual machines

One or more containers sharing network namespace

Only storage volumes

Configuration files only

20. Which component in Kubernetes is responsible for managing the overall cluster state?

Worker Node

Control Plane

Container Runtime

Service Mesh
