KCNA Kubernetes Fundamentals Practice Question
Which THREE of the following are valid options for the 'kubectl get' command to display output in different formats?
⚠ Common exam trap
CNCF often tests the distinction between output format flags (`-o`) and separate subcommands (`describe`), trapping candidates who confuse `--describe` with `-o wide` or think `-o verbose` is a real format.

Correct answer & explanation
✓
-o wide
`kubectl get -o wide` is a valid output format that displays additional details such as node names and internal IPs for pods, or cluster IPs and ports for services, beyond the default summary columns. This is a standard kubectl output flag for human-readable extended output.
