T1

Type: essay Points: 30 Prompt: Compare control plane nodes and worker nodes by listing the main responsibilities and naming at least three specific components/services on each side. Refs:

  • mat-06-kubernetes-intro#control-plane-and-worker-nodes
  • mat-06-kubernetes-intro#control-plane-services
  • mat-06-kubernetes-intro#worker-node-components Rubric:
  • Correctly distinguishes control plane responsibilities vs worker responsibilities. (10)
  • Correctly names and attributes at least three control plane components/services (e.g., API server, scheduler, controllers/controller manager, cluster store). (10)
  • Correctly names and attributes at least three worker node components (kubelet, runtime, kube-proxy) and what they do. (10)

T2

Type: mcq Points: 20 Prompt: Which control plane component is described as the front end that all commands and requests go through? Refs:

  • mat-06-kubernetes-intro#the-api-server Choices:
  • API server
  • kubelet
  • kube-proxy
  • container runtime

T3

Type: short Points: 20 Prompt: What distributed database is used as the basis for the Kubernetes cluster store? Refs:

  • mat-06-kubernetes-intro#the-cluster-store-etcd-high-availability-and-split-brain Answer: etcd

T4

Type: single_choice Points: 15 Prompt: If etcd enters a split-brain condition, what behavior is described? A) etcd deletes all cluster state B) etcd goes into read-only mode preventing updates C) etcd automatically adds replicas until quorum is restored D) etcd converts the cluster to single-node mode Refs:

T5

Type: multiple_choice Points: 15 Prompt: Which statements about Pods are consistent with the material? A) Pods are the unit of scheduling B) All containers in a Pod can be scheduled to different nodes C) A Pod is ready only when all its containers are running D) Pods are immutable and updates replace them with new Pods Refs:
