AWS Certified Advanced Networking – Specialty (ANS-C01) Study Guide: Domains and Study Plan
An AWS ANS-C01 study guide covering the four exam domains, hybrid network design, and a practical preparation plan for networking professionals.
The AWS Certified Advanced Networking – Specialty (ANS-C01) exam tests how to design, implement, operate, and secure large-scale AWS and hybrid networks. It is intended for networking professionals. The focus is how routing, connectivity, DNS, automation, and security controls work together.
This guide covers the target candidate, the four exam domains, and a preparation plan. Objectives and service scope can change, so use the latest AWS ANS-C01 exam guide as your source of truth.
Who is this exam for?
- Cloud or hybrid network engineers responsible for connectivity, routing, and network scale.
- Networking-focused architects designing multi-account or multi-Region networks, Direct Connect, VPN, or hybrid DNS.
- Cloud professionals with networking experience who want deeper AWS networking knowledge.
AWS describes its target candidate as having five or more years of networking experience and at least two years of cloud and hybrid networking experience. This is a target-candidate profile, not a registration requirement. For general architecture roles, first build the VPC and hybrid connectivity foundation covered by SAA-C03.

ANS-C01 vs SAA-C03
SAA-C03 covers network choices as part of broader architecture decisions about security, resilience, performance, and cost. ANS-C01 goes deeper into network design, implementation, operations, and security at scale. It is a networking specialty, not a required exam for every architecture role.
Exam domains and weights
Weights are percentages of scored content and can help you plan study time. Use the official guide for detailed task statements and service scope.
| Domain | Official name | Main focus | Weight |
|---|---|---|---|
| 1 | Network Design | Cloud and hybrid network topologies and connectivity | 30% |
| 2 | Network Implementation | Routing, connectivity, DNS, and network automation | 26% |
| 3 | Network Management and Operation | Monitoring, troubleshooting, changes, and operations | 20% |
| 4 | Network Security, Compliance, and Governance | Network security controls, compliance, and governance | 24% |
Design and security/governance together make up more than half of the scored content. Connect topology decisions to routing behavior, monitoring, and required security controls as you study.
How to study each domain
Domain 1: Network Design
Design topologies based on scale, accounts, Regions, and on-premises requirements. Focus on IP planning, routing boundaries, redundancy, and choosing among patterns such as Transit Gateway, VPC Peering, and PrivateLink.
Common mix-up: drawing connections without estimating route-table complexity, IP growth, or multi-Region traffic paths. Start with constraints and communication needs, then draw the topology and explain how routes propagate.
Domain 2: Network Implementation
Implement routing and connectivity between on-premises networks and AWS, and across accounts, Regions, and VPCs. This domain also covers hybrid DNS and network automation. Understand Direct Connect, Site-to-Site VPN, BGP, and Route 53 in failure scenarios.
Common mix-up: describing the primary link without the backup path, route preference, or failover behavior; or reversing DNS forwarding direction. For each connection, document the normal path, routing changes during failure, and DNS query flow.
Domain 3: Network Management and Operation
Learn to monitor and maintain hybrid and cloud networks, validate connectivity, diagnose issues, automate tasks, and make changes safely.
Common mix-up: relying on dashboards without validating the end-to-end path, or changing routes without a window, permission boundary, or rollback plan. Build a monitor → diagnose → change → verify process, and identify the evidence used at each step.
Domain 4: Network Security, Compliance, and Governance
Understand how segmentation, traffic inspection, access controls, and governance policies protect networks. Analyze centralized egress, east-west traffic, public entry points, and private connectivity as parts of the same trust boundary.
Common mix-up: treating WAF, firewalls, PrivateLink, and security groups as interchangeable. Define the traffic to protect first, then select controls for application requests, network traffic, resource access, or private service connectivity.
Check your readiness with three questions
- How would you design primary and backup paths between an on-premises data center and a dual-Region AWS environment?
- How should hybrid DNS queries be forwarded, and how would you avoid forwarding loops?
- How would you detect and prevent workloads from bypassing centralized egress inspection?
If two answers are unclear, strengthen those domains before doing more scenario practice.
Suggested study order
- Review SAA networking basics: VPCs, routes, security groups, and hybrid connectivity.
- Network design: topology, IP planning, multi-account, and multi-Region patterns.
- Network implementation: Direct Connect, VPN, BGP, DNS, and automation.
- Security and governance: trust boundaries, centralized inspection, and access controls.
- Operations: monitoring, diagnosis, change validation, and rollback.
A three-step preparation plan
- Use the official guide. Review task statements by domain instead of studying only service names.
- Map end-to-end paths. For each scenario, mark accounts, VPCs, on-premises networks, routes, DNS, inspection points, and backup paths.
- Practice and review. Group mistakes by design, implementation, operations, and security. For recurring gaps, return to the matching task and AWS documentation.
Start practicing
When you are ready, use exam code ANS-C01 to practice by domain, then revisit the matching exam objectives and official materials.
