- A
Add a startup probe with a failureThreshold high enough to cover the startup time
A startup probe allows the container extra time to start by disabling other probes until it succeeds. This is the recommended approach for slow-starting containers.
- B
Increase the timeoutSeconds on the liveness probe
Why wrong: TimeoutSeconds only affects how long each probe waits for a response, not the overall startup time threshold.
- C
Set periodSeconds on the liveness probe to 120
Why wrong: periodSeconds sets the interval between checks, not the initial delay. The probe would still run every 120 seconds after the initial delay, which might be too aggressive.
- D
Set initialDelaySeconds on the liveness probe to 120
Why wrong: This delays the first liveness check, but the liveness probe will still run after that and may kill the container if the startup is not complete within the period.
CKAD Application Observability and Maintenance Practice Question
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 have a pod that takes 2 minutes to start its application. You want to avoid the liveness probe from killing the pod during startup, but still have it active afterward. Which probe should you add to the pod spec?
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
Add a startup probe with a failureThreshold high enough to cover the startup time
A startup probe is designed for slow-starting containers. It runs only during startup and disables liveness and readiness probes until it succeeds.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Add a startup probe with a failureThreshold high enough to cover the startup time
Why this is correct

Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
