About This Domain
Domain 1 — Network Design — accounts for 30% of the ANS-C01 certification exam. This domain evaluates your understanding of design a multi-vpc connectivity solution using transit gateway or peering, implement cidr allocation and ip address management (ipam), design network segmentation and isolation strategies, and related concepts. Design and implement AWS and hybrid network architectures that meet scalability, availability, and performance requirements. To pass this section you need practical knowledge of how these services and patterns work together in real-world architectures.

- Design a multi-VPC connectivity solution using Transit Gateway or peering
- Implement CIDR allocation and IP address management (IPAM)
- Design network segmentation and isolation strategies
- Select appropriate connectivity options for workload requirements
- Design DNS architectures for hybrid and multi-account environments
