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.
5 sample questions with answers and explanations. The full bank has 1,453 questions, enough for 22 full-length practice exams.
Preview — answers shown1. VanArsdel Ltd is connecting multiple VPCs using Transit Gateway and Direct Connect. They want to ensure connections between data centers use AWS private infrastructure instead of additional circuits. Which feature enables this?
Explanation
Direct Connect Gateway DCI allows data center interconnect using AWS private infrastructure without buying separate lines. VPN connections encrypt over the internet. Internet Gateway exposes to public networks. NAT Gateway handles outbound traffic translation.
2. Best For You Organics uses Amazon CloudFront with geo-restriction. To customize responses for blocked users, which option allows changing the default 403 error?
Explanation
CloudFront allows configuring custom error pages to replace the default 403 Forbidden with messages or redirects for denied geo-restriction. Lambda@Edge can process requests but is not specific to geo-restriction errors. API Gateway handles APIs, not content delivery. Route 53 manages DNS, not error customization.
3. Contoso Corporation is migrating a high-throughput database application to AWS that requires transferring large amounts of data between Amazon EC2 instances within the same VPC. The network team is considering implementing jumbo frames to improve performance. Which benefit will jumbo frames provide in this scenario?
Explanation
Jumbo frames reduce CPU utilization by allowing larger packets that require less fragmentation and reassembly, which is beneficial for high-throughput data transfers. Encryption is not a feature of jumbo frames and requires separate protocols like IPsec. Jumbo frames are not supported over the public internet and would be dropped or fragmented. Security groups are unrelated to frame size and remain necessary for network access control.
4. Litware Inc operates a hybrid environment with 30 VPCs across three AWS regions and on-premises data centers. They require centralized traffic filtering via an approved firewall, inter-VPC connectivity, and at least 2 Gbps bandwidth from on-premises. Which solution meets these needs?
Explanation
Four 1 Gbps Direct Connect connections with ECMP provide the required bandwidth and redundancy, while transit gateway peering enables inter-region VPC connectivity and centralized inspection through the firewall. IPsec VPN alone lacks the bandwidth. Direct Connect to multiple VGWs increases complexity without proper aggregation. VPC peering doesn't support centralized filtering efficiently at scale.
5. Tailspin is setting up subnets in a VPC. For a public subnet, what is required?
Explanation
Public subnets need an Internet Gateway attached to the VPC and a route in the route table for outbound traffic. NAT Gateway is for private subnets. VPC Endpoints are for private service access. Private IPs limit internet access.
AWS and Pearson VUE run statistical forensics on every exam session, comparing your results against historical patterns to flag abnormal scores. If ANS-C01 gets flagged, AWS can invalidate the result, revoke the certification, and lock you out of the AWS Certification Program's online testing until its security team grants written approval, and AWS does not refund the exam fee either way.
ANS-C01 is a dense specialty exam, 1,453 questions deep in our bank, which is exactly why real practice matters more than a shortcut. 30 questions are free to start, each with the kind of explanation that holds up when a hiring manager asks you to walk through your reasoning, not just recite an answer key.
