Which Kubernetes resource can be used to automatically scale the number of replicas of a Deployment based on CPU or memory usage?

• HPA (Horizontal Pod Autoscaler)

• VPA (Vertical Pod Autoscaler)

• PodDisruptionBudget

• PodSecurityPolicy

What is the difference between a Kubernetes Job and a Kubernetes Deployment?

• Jobs run a specific task to completion, while Deployments ensure a set of replicas is running.

• Jobs create new Pods each time they run, while Deployments manage a fixed set of Pods.

• Jobs and Deployments are interchangeable, and can be used for the same purposes.

• Jobs are used for long-running tasks, while Deployments are used for short-lived tasks.

What is the purpose of a Kubernetes CronJob?

• To run a specific task to completion once.

• To create new Pods each time it runs.

• To ensure a set of replicas is running.

• To schedule tasks to run at specified times or intervals.
