Free Certified Kubernetes Administrator CKA practice questions

Sample question 1. Before patching worker02 you run kubectl drain worker02. It refuses to continue and reports two problems: the node runs Pods managed by DaemonSets (kube-proxy and the CNI agent), and one Deployment-managed Pod uses an emptyDir volume whose scratch data can be discarded. There are no unmanaged Pods on the node. Which flags let the drain proceed while still evicting Pods safely? (Choose two.)

1. --ignore-daemonsets
2. --force
3. --delete-emptydir-data
4. --grace-period=0
5. --disable-eviction

Sample question 2. A Gateway named edge in namespace infra has a single HTTP listener with no allowedRoutes field. An HTTPRoute in namespace shop sets parentRefs to name: edge, namespace: infra, but its status reports that it was not accepted by the parent. What change lets the route attach?

1. Set the listener's allowedRoutes.namespaces.from to All, or to Selector with a label that matches shop.
2. Create a ReferenceGrant in infra that allows HTTPRoutes from shop to reference the edge Gateway.
3. Add spec.hostnames to the HTTPRoute, because a route with no hostname is never accepted by a listener.
4. Delete the parentRefs namespace field so the HTTPRoute uses its own namespace and finds the Gateway.

Sample question 3. You need a Deployment named web in the current namespace that runs three replicas of the image nginx:1.27. Which command creates it in one step?

1. kubectl create deployment web --image=nginx:1.27 --replicas=3
2. kubectl run web --image=nginx:1.27 --replicas=3 --restart=Always
3. kubectl create deployment web --image=nginx:1.27 --count=3
4. kubectl scale deployment web --replicas=3 --image=nginx:1.27
