hard📝 Best Practice Q15 of 15
Step-by-Step Solution
Solution:
Step 1: Identify correct CPU units and values
CPU values can be specified as millicores with 'm' suffix, e.g., "250m" for 0.25 CPU.Step 2: Check request and limit order
Request must be less than or equal to limit. resources: requests: cpu: "250m" limits: cpu: "750m" sets request to 250m and limit to 750m correctly.Final Answer:
resources: requests: cpu: "250m" limits: cpu: "750m" -> Option AQuick Check:
Request 250m ≤ Limit 750m with correct units = resources: requests: cpu: "250m" limits: cpu: "750m" [OK]
Quick Trick: Use millicores with 'm' and keep request ≤ limit [OK]
Common Mistakes:
- Swapping request and limit values
- Using decimal numbers without quotes
- Not using millicores for fractional CPU
