This CKAD practice question tests your understanding of application deployment. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 have a HorizontalPodAutoscaler (HPA) that targets CPU utilization at 50%. The current average CPU utilization is 80%. The HPA has a stabilization window of 300 seconds and a scale-down policy with a periodSeconds of 60. CPU utilization drops to 40%. How long will it take for the HPA to begin scaling down?
After 300 seconds
The HPA waits the stabilization window before scaling down.
Immediately
Why wrong: The stabilization window prevents immediate scale-down.
After 60 seconds
Why wrong: 60 seconds is the periodSeconds for the scale-down policy, but the stabilization window takes precedence.
After 360 seconds
Why wrong: The stabilization window is 300 seconds; the periodSeconds is for the rate of scaling, not the delay.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
After 300 seconds
The stabilization window is the time the HPA waits before considering a scale-down decision. It will wait 300 seconds after the utilization drops below the target.
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.
After 300 seconds
Why this is correct

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
