The AWS Certified Advanced Networking – Specialty (ANS-C01) validates expert-level proficiency in designing, implementing, operating, and securing AWS and hybrid IT network architectures at scale. The certification covers a broad set of advanced networking competencies including Amazon VPC architecture, AWS Direct Connect, Amazon Route 53, transit gateway designs, IP VPN, MPLS, BGP and other routing protocols, IPv4/IPv6 subnetting and transition, and multi-region network deployments. Candidates are expected to demonstrate mastery of both AWS-native networking constructs and traditional on-premises integration patterns.
This is a Specialty-tier credential, placing it at the highest level of AWS technical certifications. It requires candidates to go beyond basic cloud networking to demonstrate the ability to automate network deployments using infrastructure-as-code tools, apply AWS security best practices within network designs, and troubleshoot complex hybrid connectivity scenarios. The exam was updated to version ANS-C01 and covers the most current AWS networking services and architectures, including centralized inspection, egress controls, and network observability tooling.
This certification is designed for experienced networking professionals who hold or are pursuing a role as an AWS networking specialist. Ideal candidates have five or more years of hands-on networking experience and at least two years of cloud and hybrid networking experience. They are typically employed in roles such as Network Engineer, Cloud Network Architect, Infrastructure Architect, or Senior Solutions Architect, and are responsible for designing and managing large-scale, enterprise-grade network environments.
Candidates who benefit most from this certification are those already working with complex AWS environments and seeking to formalize their expertise, or those transitioning from traditional network engineering roles into cloud-focused positions. AWS recommends holding an Associate- or Professional-level AWS certification before attempting this Specialty exam, as familiarity with core AWS services is assumed throughout.
There are no mandatory formal prerequisites to register for the ANS-C01 exam, but AWS strongly recommends that candidates have five or more years of professional networking experience and at least two to five years of AWS Cloud exposure. Candidates should be comfortable with AWS security best practices, AWS compute and storage services and their networking implications, and AWS service integration patterns before sitting the exam.
Recommended technical knowledge includes advanced proficiency with routing protocols (BGP, OSPF), IP subnetting (IPv4 and IPv6), virtual private network technologies, DNS design, and network automation scripting. Candidates should also have working knowledge of AWS-specific services such as Amazon VPC (including VPC peering, PrivateLink, and Transit Gateway), AWS Direct Connect, AWS Site-to-Site VPN, Amazon Route 53, AWS Network Firewall, and AWS Global Accelerator. Earning the AWS Certified Solutions Architect – Associate or AWS Certified SysOps Administrator – Associate credential first is a practical preparation step.
The ANS-C01 exam consists of 65 total questions: 50 scored questions and 15 unscored questions that are used for statistical evaluation purposes and are not identified during the exam. Question types include multiple choice (one correct answer from four options) and multiple response (two or more correct answers from five or more options); some versions of the exam guide also include matching questions where candidates pair 3–7 prompts with the correct responses. The exam must be completed within 170 minutes and costs $300 USD.
The exam is delivered through Pearson VUE, either at an authorized testing center or via online proctoring. It is available in English, Japanese, Korean, and Simplified Chinese. Results are reported as a scaled score ranging from 100 to 1,000, with a minimum passing score of 750. The scoring model is compensatory, meaning candidates do not need to pass any individual domain — only the overall scaled score matters. There is no penalty for guessing; unanswered questions are counted as incorrect.
The AWS Certified Advanced Networking – Specialty is consistently ranked among the highest-paying IT certifications globally. According to global IT Skills and Salary survey data, certified professionals earn an average of approximately $151,000 per year, with compensation ranging from roughly $60,000 to over $191,000 depending on role, seniority, and location. Common job titles held by certified professionals include Cloud Network Architect, Senior Network Engineer, Infrastructure Architect, and Cloud Solutions Architect — roles that are in strong demand as enterprises accelerate hybrid cloud adoption and multi-account AWS deployments.
As a Specialty-level credential, the ANS-C01 differentiates candidates from the large pool of Associate-certified professionals and signals deep domain expertise to employers and clients. It is particularly valued in industries with complex compliance and connectivity requirements, such as financial services, healthcare, and government contracting. Unlike broader AWS Professional certifications, this credential demonstrates focused mastery of network design and security, making it a strong complement to the AWS Certified Security – Specialty or AWS Certified Solutions Architect – Professional for professionals building comprehensive cloud expertise.

Preview — answers shown1. Contoso Corporation is migrating applications that send large data transfers within the same AWS region and wants to optimize performance. Which frame size should they enable if supported? (Select two!)
Multiple correct answersExplanation
Jumbo frames with 9000 bytes MTU reduce fragmentation for large transfers within the same region, improving efficiency. 1500 bytes MTU is standard but causes more packets. 1518 bytes is standard Ethernet frame size. 9001 bytes is not a standard size. Standard Ethernet frames are smaller and less efficient for large data.
2. Northwind Traders is implementing host-based security for EC2 instances in their VPC. They need to protect against anomalous behavior and malware. Which measures should they deploy?
Explanation
Host-based firewalls control inbound and outbound traffic per instance, while IDS/IPS systems detect anomalies and malware, providing defense in depth beyond network-level controls like ACLs.
3. Northwind Traders is approaching service limits in their AWS region and needs to view and manage quotas. Where can they access the dashboard to track and request increases for services like VPC subnets or NAT gateways?
Explanation
The AWS Service Quotas dashboard allows tracking and requesting increases for services like VPC subnets or NAT gateways. CloudWatch provides metrics but not quota management. Trusted Advisor offers recommendations but not direct quota requests. Direct Connect console is for connection management.
4. Fourth Coffee is planning to connect two VPCs in different regions over the public internet using tunneling. The company wants to avoid IP address overlaps and ensure private traffic remains encapsulated. Which protocol provides this encapsulation without built-in encryption?
Explanation
GRE encapsulates IP packets with an additional header for tunneling private traffic over public networks without encryption. IPsec includes encryption. VXLAN is for layer 2 over layer 3. TLS is for application layer security.
5. WoodGrove Bank migrates their DNS to Route 53 without downtime. The domain receives high traffic. Which steps should they follow?
Explanation
Copying records to a public hosted zone and updating name servers first propagates changes before transferring, avoiding downtime. Private zones aren't for public domains, low TTL increases load unnecessarily, and immediate transfer risks outages.
