What is the main purpose of setting resource requests and limits on Kubernetes pods for cost optimization?
ATo disable autoscaling features in the cluster
BTo control how much CPU and memory a pod can use, preventing waste
CTo increase the number of pods running simultaneously
DTo allow pods to use unlimited resources
Step-by-Step Solution
Solution:

  1. Step 1: Understand resource requests and limits

    Requests define minimum resources a pod needs; limits set maximum usage.

  2. Step 2: Link resource control to cost optimization

    By setting these, Kubernetes schedules pods efficiently and avoids resource waste.

  3. Final Answer:

    To control how much CPU and memory a pod can use, preventing waste -> Option B

  4. Quick Check:

    Resource limits prevent waste = C [OK]
Quick Trick: Requests and limits control pod resource use to save costs [OK]
Common Mistakes:
  • Thinking limits increase pod count
  • Confusing requests with autoscaling
  • Assuming unlimited resources save money
