- A
Run 'kubectl debug' to create a debugging Pod.
Why wrong: Incorrect. 'kubectl debug' is not a built-in kubectl command; it requires the EphemeralContainers feature gate and is not available in all clusters without additional configuration.
- B
Run 'kubectl edit deployment' to modify a Deployment in-place.
Correct. 'kubectl edit deployment' is a built-in command that opens the Deployment's manifest in the default editor, allowing modifications without plugins.
- C
Run 'kubectl auth reconcile' to reconcile RBAC permissions.
Why wrong: Incorrect. 'kubectl auth reconcile' is a kubectl plugin, not a native command, and requires installation.
- D
Run 'kubectl cp' to copy files to and from containers.
Correct. 'kubectl cp' is a built-in command for copying files to and from containers.
- E
Run 'kubectl logs' to view the logs of a container in a Pod.
Correct. 'kubectl logs' is a built-in command for viewing container logs.
Built-in kubectl Commands for KCNA
This KCNA practice question tests your understanding of kubernetes fundamentals. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: built-in kubectl commands. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE actions can be performed using kubectl without installing additional plugins?
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
Run 'kubectl edit deployment' to modify a Deployment in-place.
Options B, D, and E are built-in kubectl commands that work without any additional plugins. 'kubectl edit deployment' allows in-place editing of a Deployment by opening the manifest in an editor. 'kubectl cp' copies files between a local filesystem and a container. 'kubectl logs' retrieves logs from a container in a Pod. In contrast, 'kubectl debug' (A) is not a standard built-in command; it was introduced as an alpha feature and may require the EphemeralContainers feature gate. 'kubectl auth reconcile' (C) is a kubectl plugin, not a native command.

Detailed technical explanation
How to think about this question
Under the hood, 'kubectl edit' fetches the current resource manifest via the Kubernetes API, presents it in a text editor, and on save, applies the changes using a strategic merge patch. This command is part of the core kubectl command set, which includes over 30 built-in subcommands like 'get', 'describe', 'logs', 'cp', and 'exec', all of which work without plugins. The 'kubectl cp' command uses the Kubernetes API's exec subresource to transfer files via tar streams, while 'kubectl logs' retrieves container logs from the kubelet's log endpoint.
