A pod named `api-abc123` is in a CrashLoopBackOff state. The team needs to see the last few lines of the application's output to diagnose the issue. Which command should they use?

kubectl get pod api-abc123 -o yaml

kubectl exec api-abc123 -- cat /var/log/app.log

kubectl logs api-abc123 --tail=50

kubectl describe pod api-abc123

A team has a set of pods labeled `app=api` running in the `default` namespace. They need to expose these pods to other pods within the cluster using a stable DNS name. Which command creates the appropriate service?

kubectl expose deployment api --port 8080 --type NodePort

kubectl run api --image=nginx --port=8080

kubectl expose pod --selector app=api --port 8080 --type ClusterIP

kubectl create service clusterip api --tcp=8080

A cluster has three nodes: node1 and node2 are general-purpose, node3 is specialized for GPU workloads and has a taint `gpu=true:NoSchedule`. A deployment `ml-job` must run only on node3. The deployment's pod template includes a nodeSelector for `gpu=true`. However, the pods are stuck in `Pending`. What is the missing configuration?

Add a toleration for the taint `gpu=true:NoSchedule` to the pod spec.

Scale the deployment to 0 replicas and back.

Add the same taint to the pod spec.

Remove the nodeSelector and use a different label.

What is the key difference between `kubectl create` and `kubectl apply`?

`create` is declarative, while `apply` is imperative.

`apply` only works with JSON files, while `create` works with YAML.

`create` requires a file, while `apply` can use stdin only.

`apply` can update resources declaratively, while `create` only creates new resources.
