   You have a batch job that processes a queue of messages. The job should run until all messages are processed, but the number of messages is unknown. You want to run multiple pods in parallel, and the job should be considered complete when all messages are processed. Which workload resource and configuration should you use?

   • AJob with parallelism set to a fixed number, and each pod processes messages from a shared queue until the queue is empty
   • BCronJob with parallelism set to a fixed number
   • CDeployment with replicas set to a fixed number, and each pod processes messages until the queue is empty
   • DJob with completions set to a fixed number, and each pod processes a fixed subset of messages

   You have a Deployment with 3 replicas. You need to perform a canary release by routing a small percentage of traffic to a new version. You plan to create a new Deployment for the new version and use a Service to route traffic. However, you notice that the ReplicaSet of the original Deployment is still managing the old pods. What is the best approach to achieve the canary release?

   • AModify the existing Deployment's image to the new version and use a rolling update
   • BDelete the existing Deployment and create a new one with the new image
   • CCreate a second Deployment for the new version and use a Service selector that includes both versions, with a small number of replicas for the new version
   • DScale the existing Deployment to 0 and create a new Deployment with the new image
