Step-by-Step Solution
Solution:
Step 1: Understand prefix delegation in VPC CNI
Prefix delegation allows assigning multiple IP addresses per ENI, improving IP utilization efficiency.Step 2: Evaluate other options
Increasing nodes without subnet change does not reduce IP use; disabling VPC CNI changes networking; manual static IPs are impractical.Final Answer:
Enable prefix delegation to assign multiple IPs per ENI -> Option DQuick Check:
Prefix delegation = better IP use per ENI [OK]
Quick Trick: Prefix delegation packs more IPs per ENI, saving IPs [OK]
Common Mistakes:
- Thinking more nodes reduce IP usage
- Disabling VPC CNI without replacement
- Trying manual static IP assignment
