Your team is working towards using the desired state configuration for your application deployed on the GKE cluster. You have YAML files for the Kubernetes Deployment and Service objects. Your application is designed to have 2 pods, which is defined by the replicas parameter in app-deployment.yaml. Your service uses GKE Load Balancer which is defined in app-service.yaml. You created the Kubernetes resources by running `kubectl apply -f app-deployment.yaml` and `kubectl apply -f app-service.yaml`. Your deployment is now serving live traffic but is suffering from performance issues. You want to increase the number of replicas to 5. What should you do in order to update the replicas in existing Kubernetes deployment objects?

Real Exam

Disregard the YAML file. Enable autoscaling on the deployment to trigger on CPU usage and set max pods to 5. kubectl autoscale myapp --max=5 --cpu-percent=80
