This CKAD practice question tests your understanding of application observability and maintenance. 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.
You need to view resource usage (CPU and memory) for all pods in the 'default' namespace. Which command should you use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
kubectl top pods
This command shows CPU and memory usage for pods in the current namespace.
kubectl logs pods
Why wrong: This shows logs, not resource usage.
kubectl describe pods
Why wrong: This shows pod details but not real-time resource usage.
kubectl top nodes
Why wrong: This shows resource usage for nodes, not pods.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
kubectl top pods
Option A is correct because `kubectl top pods` is the command specifically designed to display real-time CPU and memory usage metrics for pods in a Kubernetes cluster. It relies on the metrics server to collect resource usage data and presents it in a concise table format, making it the appropriate tool for viewing resource consumption in the 'default' namespace.
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.
kubectl top pods
Why this is correct
This command shows CPU and memory usage for pods in the current namespace.
Clue confirmation
The clue word "which command" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
kubectl logs pods
Why it's wrong here
This shows logs, not resource usage.
kubectl describe pods
Why it's wrong here
This shows pod details but not real-time resource usage.
kubectl top nodes
Why it's wrong here
This shows resource usage for nodes, not pods.
Common exam traps
The trap here is that candidates often confuse `kubectl top pods` with `kubectl describe pods` or `kubectl logs`, mistakenly thinking that descriptive or log commands provide resource usage data, but only `kubectl top` accesses the metrics server for real-time utilization.
Trap categories for this question
Command / output trap
This shows logs, not resource usage.
Detailed technical explanation
The `kubectl top` command relies on the Kubernetes Metrics Server, which collects resource metrics from the kubelet's cAdvisor via the Summary API. By default, `kubectl top pods` shows metrics for all namespaces, but you can filter to a specific namespace using the `-n` flag (e.g., `kubectl top pods -n default`). In real-world scenarios, this command is essential for identifying resource-hungry pods during troubleshooting or capacity planning, especially when combined with `--sort-by` to order by CPU or memory usage.
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 CKAD 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.
