AWS - EKS

In an Amazon EKS cluster, how does the AWS VPC CNI plugin manage pod networking?

ABy assigning each pod an IP address from the VPC subnet, enabling native VPC networking

BBy creating an overlay network using VXLAN to isolate pod traffic

CBy routing pod traffic through a NAT gateway to access the internet

DBy using a separate IP address pool managed outside the VPC

Step-by-Step Solution

Solution:

Step 1: Understand VPC CNI Functionality
The AWS VPC CNI plugin assigns IP addresses to pods directly from the VPC subnet, allowing pods to have native VPC networking capabilities.
Step 2: Contrast with Other Networking Models
Unlike overlay networks (VXLAN) or NAT-based approaches, VPC CNI integrates pods directly into the VPC network.
Final Answer:
By assigning each pod an IP address from the VPC subnet, enabling native VPC networking -> Option A
Quick Check:
Pods get IPs from VPC subnet, no overlay used [OK]

Quick Trick: VPC CNI assigns pod IPs directly from VPC subnet [OK]
