Exam Professional Cloud Developer topic 1 question 237 discussion

Here's a link to the official Kubernetes documentation on the SIGTERM signal: https://kubernetes.io/docs/concepts/containers/container-lifecycle-hooks/#container-hooks And here's a link to the official Kubernetes documentation on how to handle the SIGTERM signal in your application: https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#define-a-graceful-shutdown-for-your-application

I think Mr. TNT87 is very exceed person, because I know he answered very exellent answer in other questions. But this question's demand is "You want to update your application to make sure that it completes a graceful shutdown.". It's not about avoiding shutdown. I think the answer is what you should do in occuring shutdown. So me too, I think "to prevent the Pod from being forcefully shut dow n." doesn't anser for demand. I think also right answer is A.

Option B, Configuring a PodDisruptionBudget, is used to control the number of replicas of a pod that can be down simultaneously. It prevents voluntary disruption of the pods, but it does not prevent forced termination of the pods. When a pod is terminated forcefully, for example, during a node failure, the PodDisruptionBudget does not come into play. In this scenario, you need to handle the termination gracefully in your application code, as described in option A.
