An application Deployment is configured with 3 replicas. The team expects a traffic spike and needs to temporarily increase the number of running pods to 6. After the spike, they want to return to 3 replicas. What is the most efficient way to handle this?

Edit the Deployment YAML to change replicas to 6 and later back to 3

Use `oc scale deployment/app --replicas=6` and later `oc scale deployment/app --replicas=3`

Delete and recreate the Deployment with 6 replicas

Create a second Deployment with 3 replicas and a Service

A developer wants to deploy a new microservice using the OpenShift web console. The microservice requires environment variables and a config file that should be mounted as a volume. Which approach should the developer use?

Hardcode the environment variables in the Deployment YAML

Create a Secret and mount it as a volume

Use a PersistentVolumeClaim to store the config file

Create a ConfigMap and reference it in the Deployment's pod template

Which command is used to increase the number of replicas for a deployment named 'web' to 5?

oc rollout restart deployment/web

oc scale deployment/web --replicas=5

oc set image deployment/web app=nginx:1.19

An administrator needs to update a Deployment's container image to a new version. The update should be performed with zero downtime, and the administrator wants to monitor the rollout progress. Which approach should be used?

Delete the Deployment and recreate it with the new image

Use `oc edit deployment/app` to change the image and save

Use `oc scale deployment/app --replicas=0` and then scale back up

Use `oc set image deployment/app app=image:v2` and then `oc rollout status deployment/app`
