Which three functions are provided by the components within the Kubernetes control plane? (Choose three.)
Within the Kubernetes control plane, there are specific components designed to manage the cluster's state and provide operational functions. The scheduler balances pods across the nodes within a Kubernetes cluster, ensuring optimal resource utilization and pod placement. The etcd component stores Kubernetes cluster data in a key-value data store and serves as the cluster’s primary datastore. The controller manager watches the API for changes and responds with appropriate actions to maintain the desired state of the system. Hence, the functions of balancing pods, storing cluster data, and watching the API for changes are all crucial roles provided by the control plane components.
I would say the correct answers are: https://www.examtopics.com/exams/vmware/2v0-33-22/view/2/# A. Balances pods across the nodes within a Kubernetes cluster. - Scheduler D. Stores Kubernetes cluster data in a key-value data store. - etcd E. Watches the API for changes and responds with appropriate actions. - Controller manager Kubernetes Components https://kubernetes.io/docs/concepts/overview/components/
The A answer is not correct The Kubernetes scheduler is a separate component that is responsible for scheduling pods onto available nodes within the cluster. The control plane components, on the other hand, are responsible for managing the overall state of the cluster and providing an interface for users and administrators to interact with the cluster.
kube-scheduler is one component of the Control Plane
as per https://kubernetes.io/docs/concepts/overview/components/ other options do not fit
B. Ensures that containers are running in a pod. D. Stores Kubernetes cluster data in a key-value data store. E. Watches the API for changes and responds with appropriate actions.
Kubernetes control plane has components as lists. Controller Manager: Runs the controllers that watch the API for changes and that respond with appropriate actions. Scheduler: Balances pods across the nodes within a Kubernetes cluster. API Server: Entry point into the Kubernetes platform. etcd: A key-value datastore where Kubernetes cluster data is stored, for example, cluster configuration and current state.
I would say BDE are the most likely answers
I would say BDE
BDE are the correct option : B. Ensures that containers are running in a pod. This function is managed by the kubelet, which communicates with the control plane to ensure containers are running in a Pod. However, strictly speaking, the kubelet runs on each node and is not part of the control plane. But the control plane does determine how many instances of your application should be running. D. Stores Kubernetes cluster data in a key-value data store. The etcd component is a consistent and highly-available key-value store used as Kubernetes' backing store for all cluster data. E. Watches the API for changes and responds with appropriate actions. The Controller Manager does this. It regulates controllers that handle state, such as ensuring the desired number of replicas for a deployment exists or handling node operations.
Is BDE
The Kubernetes control plane includes various components responsible for managing and orchestrating containers and pods, and one of those components is the kubelet. The kubelet is responsible for ensuring that the containers specified in a pod are running and healthy. It communicates with the container runtime to start, stop, and monitor containers as needed, and reports back to the control plane if any issues arise. So option B is indeed one of the functions provided by the components within the Kubernetes control plane.
kubelet is not a component of the Kubernetes Control Plane. Components of Control Plane https://kubernetes.io/docs/concepts/overview/components/
