AWS Certified Advanced Networking - Specialty (ANS-C01): What It Is and When to Use It

Definition

The AWS Certified Advanced Networking - Specialty (ANS-C01) is a certification intended for individuals who perform a complex networking specialist role. It validates a candidate's ability to design, implement, manage, and secure AWS and hybrid network architectures at scale.

Important Note: AWS has announced the retirement of the ANS-C01 exam. The last day to take the exam is August 25, 2026. Certifications earned before this date will remain active for the standard three-year period.

How It Works

This certification is earned by passing the ANS-C01 exam, which assesses a deep level of technical skill and experience in AWS networking. The exam is designed to test a candidate's ability to perform complex, hands-on networking tasks and architectural design.

• Exam Code: ANS-C01
• Format: 65 questions, featuring a combination of multiple-choice and multiple-response formats.
• Duration: 170 minutes to complete the exam.
• Scoring: Results are reported as a scaled score between 100 and 1,000. The minimum passing score is 750. The exam uses a compensatory scoring model, meaning you only need to pass the overall exam, not each individual section.
• Prerequisites: While there are no mandatory prerequisites, AWS recommends the target candidate have five or more years of networking experience, with at least two years of hands-on experience designing and implementing cloud and hybrid network solutions using AWS. Earning an Associate or Professional-level certification first is also beneficial.

Key Features and Limits

The exam is structured around four key domains, each with a specific weighting:

• Domain 1: Network Design (30%): This is the largest section and focuses on designing complex network solutions. It covers AWS and hybrid network architectures, routing strategies, DNS solutions, and designing for high availability and disaster recovery.
• Domain 2: Network Implementation (26%): This domain tests the ability to implement routing and connectivity, configure complex hybrid and multi-account DNS architectures, and automate network infrastructure.
• Domain 3: Network Management and Operation (20%): This section covers the tools and techniques for monitoring, logging, and troubleshooting network infrastructure to ensure performance and reliability.
• Domain 4: Network Security, Compliance, and Governance (24%): This domain focuses on implementing security controls, designing for compliance, and managing network security in a scalable and automated fashion.

Common Use Cases

This certification is ideal for professionals in the following roles:

• Network Engineers/Architects: Professionals responsible for designing and implementing scalable, secure, and resilient network infrastructure on AWS and in hybrid environments.
• Cloud Solutions Architects: Architects who need to demonstrate deep expertise in the networking components of their overall solutions, especially in complex enterprise scenarios.
• DevOps and Automation Engineers: Individuals focused on automating the deployment and management of network infrastructure using Infrastructure as Code (IaC) tools.
• IT Security Professionals: Security specialists who need to understand how to secure complex network architectures, implement inspection and threat detection, and ensure compliance.

Pricing Model

The AWS Certified Advanced Networking - Specialty exam costs $300 USD. Prices may vary based on region and currency exchange rates. Upon passing any AWS certification exam, you receive a voucher for 50% off your next exam, which can be applied to recertification or any other exam.

Pros and Cons

Pros:

• Validates Elite Skills: It is one of the most challenging and respected AWS certifications, proving a deep level of expertise in a critical domain.
• Career Advancement: Holding this certification can lead to senior-level roles and higher earning potential, as it demonstrates skills that are in high demand.
• Deep Technical Knowledge: The preparation process requires a thorough understanding of a wide range of AWS networking services and how they interoperate, significantly enhancing your practical skills.
• Increased Credibility: It boosts confidence and credibility with colleagues and clients when designing and discussing complex network architectures.

Cons:

• High Difficulty: The exam is notoriously difficult, requiring extensive hands-on experience and in-depth study.
• Significant Time Investment: Preparing for the exam demands a substantial commitment of time and effort for study and hands-on practice.
• Exam Retirement: With the exam being retired in August 2026, new candidates have a limited window to achieve this specific certification.

Comparison with Alternatives

• AWS Certified Solutions Architect - Professional (SAP-C02): The SAP-C02 certification has a broader focus on designing comprehensive solutions across multiple domains, including cost optimization, performance, and migration. The ANS-C01 is a deep dive specifically into networking, covering topics like BGP, Direct Connect, and complex routing scenarios in much greater detail.

• AWS Certified Security - Specialty (SCS-C02): The Security Specialty focuses on a wide range of AWS security services and topics, such as IAM, KMS, incident response, and data protection. While there is overlap, the ANS-C01 focuses on network-centric security, such as the implementation of firewalls, IDS/IPS systems, security groups, NACLs, and securing data-in-transit.

Exam Relevance

Candidates preparing for the ANS-C01 exam must have a deep, practical understanding of a wide array of AWS services. Key topics include:

• Hybrid Connectivity: Mastery of AWS Direct Connect, AWS Site-to-Site VPN, AWS Client VPN, and how to build resilient and high-performance connections between on-premises data centers and AWS.
• VPC and Transit Gateway: Advanced Amazon Virtual Private Cloud (VPC) design, including multi-account architectures, IP addressing (IPv4 and IPv6), routing, and interconnecting VPCs and on-premises networks at scale using AWS Transit Gateway.
• DNS and Content Delivery: In-depth knowledge of Amazon Route 53 for DNS resolution in hybrid scenarios (including Route 53 Resolver endpoints) and Amazon CloudFront for global content delivery.
• Network Security and Inspection: Implementing security services like AWS Network Firewall, AWS WAF, and Gateway Load Balancer for centralized traffic inspection and threat protection.
• Global Networking: Using services like AWS Global Accelerator and inter-region VPC peering to build applications with a global footprint.

Frequently Asked Questions

Q: What are the prerequisites for the ANS-C01 exam?

A: There are no formal prerequisites. However, AWS recommends that candidates have at least five years of general networking experience and two or more years of hands-on experience with AWS cloud and hybrid networking.

Q: How long is the AWS Certified Advanced Networking - Specialty certification valid?

A: Like all AWS certifications, the ANS-C01 is valid for three years. To maintain your certified status, you must recertify before the expiration date.

Q: What is the best way to prepare for the ANS-C01 exam?

A: A combination of hands-on experience, studying the official AWS exam guide, taking specialized training courses, and using practice exams is the most effective strategy. Focus on building real-world solutions with services like AWS Transit Gateway, AWS Direct Connect, and Amazon Route 53 to solidify your understanding of the concepts tested on the exam.
