Amazon Exam ANS-C00 Topic 9 Question 23 Discussion

A company is deploying a new web application that uses a three-tier model with a public-facing Network Load Balancer and web servers in an Amazon VPC. The application servers are hosted in the company's data center. There is an AWS Direct Connect connection between the VPC and the company's data center. Load testing results indicate that up to 100 servers, equally distributed across multiple Availability Zones, are required to handle peak loads.

The Network Engineer needs to design a VPC that has a /24 CIDR assigned to it.

How should the Engineer allocate subnets across three Availability Zones for each tier?
