What is the main purpose of the Vertical Pod Autoscaler in Kubernetes?

ASchedule pods to specific nodes manually

BScale the number of pod replicas up or down

CManage network policies between pods

DAutomatically adjust CPU and memory requests for pods based on usage

Step-by-Step Solution

Solution:

Step 1: Understand VPA's role
The Vertical Pod Autoscaler changes resource requests (CPU, memory) for pods automatically based on their usage.
Step 2: Differentiate from other autoscalers
Unlike Horizontal Pod Autoscaler, which changes pod count, VPA adjusts resource limits inside pods.
Final Answer:
Automatically adjust CPU and memory requests for pods based on usage -> Option D
Quick Check:
VPA adjusts resources, not pod count [OK]

Quick Trick: VPA changes pod resources, not pod numbers [OK]
