200-901 Practice Question: A developer is writing a Kubernetes Deployment…
A developer is writing a Kubernetes Deployment YAML and wants to set a CPU limit of 500 millicores. Which of the following is the correct YAML snippet?
⚠ Common exam trap
Cisco often tests the distinction between `limits` and `requests`, and the correct YAML indentation hierarchy, tricking candidates who confuse the two or misplace the `limits` key under `resources`.
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
✓
spec: containers: - resources: limits: cpu: 500m
Kubernetes resource limits are specified under the `resources.limits` key, and CPU limits are expressed in millicores using the `m` suffix. The YAML must use correct indentation: `limits:` is a child of `resources:`, and `cpu: 500m` is a valid value (500 millicores = 0.5 CPU cores).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
spec: containers: - resources: limit: cpu: "500m"
Why it's wrong here
Misspelled 'limit' instead of 'limits'.
- ✗
spec: containers: - resources: requests: cpu: "500m"
Why it's wrong here
This sets requests, not limits.
- ✗
spec: containers: - resources: limits: cpu: "500m"
Why it's wrong here
Incorrect indentation; limits should be nested under resources, not at same level.
- ✓
spec: containers: - resources: limits: cpu: 500m
Why this is correct
Correct syntax: limits under resources, CPU as a string with 'm' suffix without quotes (YAML interprets as string).
