                                                    NEW QUESTION # 137
                                                    Your organization uses multiple cloud providers and wants to ensure that your applications can run seamlessly across different environments. What open standard would be most beneficial for this scenario?

                                                    Answer: E

                                                    Explanation:
                                                    CloudEvents is an open standard for eventing, enabling applications to communicate events across different cloud providers and platforms. This helps ensure portability and interoperability, allowing your applications to run consistently across multiple environments without tight coupling to specific cloud services.


                                                    NEW QUESTION # 138
                                                    Which of the following options include resources cleaned by the Kubernetes garbage collection mechanism?

                                                    Answer: C

                                                    Explanation:
                                                    Kubernetes garbage collection (GC) is about cleaning up API objects and related resources that are no longer needed, so the correct answer is D. Two big categories it targets are (1) objects that have finished their lifecycle (like terminated Pods and completed Jobs, depending on controllers and TTL policies), and (2)
                                                    "dangling" objects that are no longer referenced properly-often described as objects without owner references (or where owners are gone), which can happen when a higher-level controller is deleted or when dependent resources are left behind.
                                                    A key Kubernetes concept here is OwnerReferences: many resources are created "owned" by a controller (e.
                                                    g., a ReplicaSet owned by a Deployment, Pods owned by a ReplicaSet). When an owning object is deleted, Kubernetes' garbage collector can remove dependent objects based on deletion propagation policies (foreground/background/orphan). This prevents resource leaks and keeps the cluster tidy and performant.
                                                    The other options are incorrect because they refer to cleanup tasks outside Kubernetes GC's scope. Kubelet logs (B/C) are node-level files and log rotation is handled by node/runtime configuration, not the Kubernetes garbage collector. Unused container images (C) are managed by the container runtime's image GC and kubelet disk pressure management, not the Kubernetes API GC. Nodes deleted by a cloud controller (B) aren' t "garbage collected" in the same sense; node lifecycle is handled by controllers and cloud integrations, but not as a generic GC cleanup category like ownerRef-based object deletion.
                                                    So, when the question asks specifically about "resources cleaned by Kubernetes garbage collection," it's pointing to Kubernetes object lifecycle cleanup: terminated Pods, completed Jobs, and orphaned objects- exactly what option D states.
                                                    =========


                                                    NEW QUESTION # 139
                                                    What is the default eviction timeout when the Ready condition of a node is Unknown or False?

                                                    Answer: C

                                                    Explanation:
                                                    The default eviction timeout for a node whose Ready condition is Unknown or False is five minutes before pods on that node are evicted.
