What is the main advantage of dynamic scaling in container orchestration?

It allows the application to handle varying load by adjusting resources automatically

It eliminates the need for load balancing

It guarantees that all containers run on the same host

It removes the need for monitoring

A company has a Kubernetes cluster with a mix of workloads. One team runs a critical application that must always have enough resources, while another team runs a best-effort batch workload that can be interrupted. The company wants to ensure that the critical application is never starved of resources, while also making efficient use of the cluster. What is the most appropriate configuration?

Set resource limits for the critical application and use a PriorityClass with a lower value for it than for the batch workload.

Use a ResourceQuota to limit the batch workload's namespace and a LimitRange to cap the critical application's resource usage.

Deploy the critical application on dedicated nodes using nodeSelectors and the batch workload on the remaining nodes.

Set resource requests for the critical application and use a PriorityClass with a higher value for it than for the batch workload.

What is the primary benefit of using an orchestration platform to deploy containers compared to manually starting containers on each host?

It automates the placement and ensures the desired number of replicas are running

It removes the need for monitoring and logging

It eliminates the need to build container images

It guarantees zero downtime during all deployments

In Kubernetes, which feature allows the number of pod replicas to automatically adjust based on observed CPU utilization or custom metrics?

Horizontal Pod Autoscaler (HPA)

Which security best practice is recommended for container images used in orchestration?

Scan images for vulnerabilities before deployment

Store secrets directly in container images

Run containers with root privileges by default

Disable all security policies to improve performance
