KCNA Kubernetes Fundamentals Practice Question
Which kubectl command is used to view detailed information about a Kubernetes resource?
⚠ Common exam trap
A common mix-up: candidates confuse `kubectl get` (which shows a summary) with `kubectl describe` (which shows detailed information), especially when they see the word 'get' and assume it retrieves all details.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
kubectl describe
The `kubectl describe` command retrieves detailed, multi-section information about a specific Kubernetes resource, including events, status conditions, and configuration details. Unlike `kubectl get`, which shows a summary, `kubectl describe` provides a deep dive into the resource's current state, making it the correct choice for viewing detailed information.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
kubectl describe
Why this is correct
kubectl describe fetches a resource's aggregated state and surfaces detailed information, including events, conditions and configuration, for a named object. This directly satisfies the stem's requirement for viewing detailed resource information, unlike kubectl get, which returns only summary or tabular output.
- ✗
kubectl get
Why it's wrong here
kubectl get lists resources and shows summary columns, not the detailed state, events and configuration that describe provides. It tempts because get is the everyday command for querying resources, yet it lacks the verbose per-object output the question asks for.
- ✗
kubectl exec
Why it's wrong here
kubectl exec opens an interactive shell or runs a command inside a running container; it does not report resource metadata. It tempts because exec is used for live pod troubleshooting, but viewing detailed resource information requires kubectl describe.
- ✗
kubectl logs
Why it's wrong here
kubectl logs retrieves container stdout/stderr for a pod, not resource details. It tempts because log inspection is a genuine troubleshooting task, but the command that returns full resource detail, including events and status, is kubectl describe.
