AWS - EKS

ACreate multiple EKS clusters in different regions

BAttach multiple subnets to the worker node group and configure VPC CNI accordingly

CUse a single subnet and rely on NAT gateways

DAssign IPs manually to pods from different subnets

Step-by-Step Solution

Solution:

Step 1: Understand subnet attachment for worker nodes
Attaching multiple subnets to worker nodes allows pods to get IPs from any of those subnets, improving availability.
Step 2: Exclude unrelated or impractical options
Multiple clusters in different regions is not subnet configuration; single subnet limits availability; manual IP assignment is impractical.
Final Answer:
Attach multiple subnets to the worker node group and configure VPC CNI accordingly -> Option B
Quick Check:
Multiple subnets on nodes = pods get IPs from all subnets [OK]

Quick Trick: Multiple subnets on nodes enable multi-subnet pod IPs [OK]
