Creating physical servers
Managing Kubernetes clusters
Managing IP addresses
Managing data backups
7. What is the main role of a node in a Kubernetes cluster?
Running containerized workloads in Pods
Storing data backups
Managing user access
Creating Virtual Machines
8. What is a Pod in Kubernetes?
A tool for managing physical servers
A group of containers with shared network and storage
A type of Virtual Machine
A load balancer
9. Which component of Kubernetes is responsible for restarting containers when they fail?
Kube-scheduler
Kube-controller

Handling DNS resolution
Managing network traffic to and from the Pods
Scheduling Pods on nodes
Providing storage orchestration
11. How does Kubernetes handle the communication between different Pods?
By using a centralized messaging queue
Through the Kubernetes Service resource
With unique cluster-wide IP addresses for each Pod
Through the use of network load balancers

They dictate the physical network setup
They only apply to external traffic
15. What does Kubernetes do if a container does not respond to a user-defined health check?
Restarts the container
Kills the container
It scales down the number of replicas
Increases the container's resources
