Kubernetes - Resource Management

Given this pod spec snippet, what QoS class will Kubernetes assign?

resources:
  requests:
    cpu: '100m'
    memory: '128Mi'
  limits:
    cpu: '100m'
    memory: '128Mi'

ABurstable

BBestEffort

Cnull

DGuaranteed

Step-by-Step Solution

Solution:

Step 1: Compare requests and limits in the pod spec
Requests and limits for both CPU and memory are equal (100m CPU and 128Mi memory).
Step 2: Determine QoS class based on equality
When requests equal limits for all resources, Kubernetes assigns Guaranteed QoS.
Final Answer:
Guaranteed -> Option D
Quick Check:
Requests = Limits means Guaranteed [OK]

Quick Trick: Equal requests and limits means Guaranteed QoS [OK]
