Kubernetes - Resource Management

Given this VPA configuration snippet, what will happen when the pod's CPU usage increases beyond the current request?

apiVersion: autoscaling.k8s.io/v1
kind: VerticalPodAutoscaler
metadata:
  name: example-vpa
spec:
  targetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: example-app
  updatePolicy:
    updateMode: "Auto"

AThe VPA will automatically update the pod's CPU requests to match usage

BThe pod replicas will increase to handle the load

CThe pod will restart immediately to apply new resources

DNothing happens until manual intervention

Step-by-Step Solution

Solution:

Step 1: Understand updateMode Auto
When updateMode is Auto, VPA automatically adjusts resource requests without manual steps.
Step 2: Effect on pod resources
VPA changes CPU and memory requests to match observed usage, improving stability and efficiency.
Final Answer:
The VPA will automatically update the pod's CPU requests to match usage -> Option A
Quick Check:
updateMode Auto means automatic resource adjustment [OK]

Quick Trick: Auto updateMode means VPA adjusts resources automatically [OK]

Common Mistakes:

Confusing VPA with Horizontal Pod Autoscaler scaling pods
Thinking pods restart immediately on resource change
Assuming manual approval is needed with Auto mode
