You have a DaemonSet that runs a logging agent on every node. You need to update the agent to a new version, but you want to ensure that the update does not cause all nodes to be unavailable at once. You also want to control the rollout speed. What should you do?

Use a Deployment with replicas equal to the number of nodes

Use a StatefulSet with replicas equal to the number of nodes

Delete the DaemonSet and recreate it with the new image

Configure the DaemonSet's updateStrategy to RollingUpdate with maxUnavailable: 1

You have a Deployment with 5 replicas. You notice that the ReplicaSet created by the Deployment is managing the pods. You need to scale the application to 10 replicas. What is the recommended way to achieve this?

Update the replicas field in the Deployment's spec and apply the change

Create a second Deployment with 5 replicas

Delete the ReplicaSet and create a new one with 10 replicas

Directly edit the ReplicaSet's replicas field
