Kubernetes - Namespaces

Given this ResourceQuota YAML applied to namespace 'test':

apiVersion: v1
kind: ResourceQuota
metadata:
  name: test-quota
  namespace: test
spec:
  hard:
    cpu: "4"
    memory: 8Gi
    pods: "10"

What happens if a pod requesting 5 CPUs is created in 'test' namespace?

APod creation fails due to exceeding CPU quota

BPod is created successfully, CPU quota ignored

CPod is created but CPU usage is throttled

DPod creation fails due to exceeding memory quota

Step-by-Step Solution

Solution:

Step 1: Analyze ResourceQuota limits
The quota limits CPU to 4 cores total in the namespace.
Step 2: Check pod CPU request against quota
A pod requesting 5 CPUs exceeds the 4 CPU limit, so creation is denied.
Final Answer:
Pod creation fails due to exceeding CPU quota -> Option A
Quick Check:
Pod CPU request > quota = creation fails = A [OK]

Quick Trick: Pod CPU request must not exceed namespace CPU quota [OK]
