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. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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 of the following are valid options for the 'kubectl get' command to display output in different formats?
-o verbose
Why wrong: There is no 'verbose' output format; use 'wide' for more detail.
-o wide
Output with additional details.
-o json
Output in JSON format.
-o yaml
Output in YAML format.
--describe
Why wrong: 'describe' is a separate kubectl command, not an output format.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
-o wide
Option B is correct because `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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
-o verbose
Why it's wrong here
There is no 'verbose' output format; use 'wide' for more detail.
-o wide

Common exam traps
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.
Trap categories for this question
Command / output trap
There is no 'verbose' output format; use 'wide' for more detail.
Detailed technical explanation
The `-o` flag in kubectl accepts specific format strings like `json`, `yaml`, `wide`, `name`, `custom-columns`, `jsonpath`, and `go-template`. The `wide` format adds columns that vary by resource type—for pods, it adds `NODE` and `IP`; for services, it adds `EXTERNAL-IP` and `PORT(S)`. This is implemented server-side via the Kubernetes API's table-based output, where the server returns column definitions and rows, and kubectl formats them accordingly.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the KCNA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
