Network engineers who hold the AWS Certified Advanced Networking Specialty earn a median salary roughly $20,000–$30,000 higher than peers with only associate-level AWS credentials, according to compensation data aggregated from LinkedIn and Glassdoor. That gap isn't just the cert — it's because the knowledge required to pass ANS-C01 is the same knowledge companies pay heavily for: designing resilient hybrid architectures, securing traffic at the VPC level, and automating network operations at scale. This guide covers what the exam actually tests, who should bother, how to prepare efficiently, and which courses are worth your time.
What the AWS Certified Advanced Networking Specialty Exam Actually Tests
The ANS-C01 exam (the current version, replacing the retired ANS-C00) is structured around five domains. AWS publishes the exact weightings in the official exam guide, and they're worth knowing before you plan your study time:
- Domain 1 – Network Design (30%): VPC architectures, multi-account connectivity via Transit Gateway, AWS PrivateLink, and hybrid topologies.
- Domain 2 – Network Implementation (26%): Building and configuring the designs from Domain 1 — routing tables, BGP on Direct Connect, Site-to-Site VPN failover.
- Domain 3 – Network Management and Operation (20%): Monitoring with VPC Flow Logs, Reachability Analyzer, Network Manager; automation with CloudFormation and AWS CLI.
- Domain 4 – Network Security, Compliance, and Governance (14%): Security groups vs. NACLs, AWS Network Firewall, Shield, WAF, and inspection architectures.
- Domain 5 – Networking Services and Features (10%): CloudFront, Global Accelerator, Route 53 Resolver, DNS design patterns.
The practical implication: over half the exam weight sits in Domains 1 and 2. If you're short on study time, prioritize Transit Gateway design patterns and Direct Connect/VPN hybrid connectivity scenarios above everything else. Scenario-based questions dominate — AWS will give you a multi-account architecture with latency and compliance requirements and ask you to select the correct combination of services. Memorizing service descriptions is not enough.
Prerequisites: Who Should Sit the AWS Certified Advanced Networking Specialty
AWS recommends five years of networking experience and one to two years of AWS hands-on work before attempting this exam. That's roughly correct, but the more useful framing is skill-based:
- You can configure BGP (including communities, prepending, and MED attributes) without looking it up
- You understand subnetting, route propagation, and CIDR overlap issues at a working level — not just conceptually
- You've actually used VPC peering, Transit Gateway, or Direct Connect in a real or lab environment
- You hold at least one AWS associate-level certification (Solutions Architect Associate or SysOps Administrator)
If you're strong on on-premises networking but light on AWS, the Solutions Architect Associate is a reasonable prerequisite to take first. It covers VPC fundamentals that ANS-C01 assumes you already know. If you're already working in AWS but haven't touched networking deeply, spend four to six weeks doing hands-on labs in a personal AWS account before sitting this exam — reading alone won't cut it.
There is no mandatory prerequisite certification. AWS doesn't enforce ordering. But candidates who attempt ANS-C01 without an associate cert typically score lower on Domain 1 scenario questions that require connecting networking choices to broader architectural trade-offs.
Top Courses for the AWS Certified Advanced Networking Specialty
The course market for this exam is thin compared to the SAA-C03 or Solutions Architect Professional. That actually helps — there are two or three genuinely good options and not much noise.
AWS Certified Advanced Networking Specialty Course [ANS-C01]
The most directly targeted course available, covering all five exam domains with hands-on labs. Rated 9.6 on Udemy, and unlike many specialty courses it was updated for the ANS-C01 exam objectives rather than recycled from the retired version. Start here if you want a single structured path from Domain 1 through Domain 5.
AWS SAA-C03 Practice: 850+ Questions on Networking
A question bank focused specifically on networking scenarios within the AWS ecosystem. While technically scoped to the SAA-C03, the overlap with ANS-C01 Domain 1 and Domain 2 is substantial — Transit Gateway, VPC peering, route table behavior, and hybrid connectivity questions appear throughout. Useful as supplementary drilling, especially if you're already strong on theory but weak on exam pacing.
Google Cloud IAM and Networking for AWS Professionals
Counterintuitive pick, but understanding how another major cloud provider implements networking concepts (shared VPCs, VPC peering, hybrid connectivity) sharpens your mental model of what's AWS-specific versus what's a general networking principle. Particularly useful for Domain 4 security questions where the "why" of AWS design choices becomes clearer when you've seen an alternative implementation.
AWS Certified Solutions Architect Associate (SAA-C03)
If you're not yet holding an associate-level cert, this is the correct starting point before ANS-C01. Covers VPC fundamentals, security groups, routing, and hybrid connectivity at the level ANS-C01 Domain 1 assumes as baseline knowledge. Don't skip this step if you're new to AWS networking.
Exam Logistics and Passing Strategy
The ANS-C01 exam is 65 questions, 170 minutes, with a passing score of 750 out of 1000. AWS uses scaled scoring, so a raw percentage doesn't map directly to the 750 threshold — but roughly 70-75% correct on practice exams is a reasonable target before scheduling.
A few structural points that affect how you study:
- Multiple-response questions: Some questions require selecting two or three correct answers from five options. There's no partial credit. These are where most candidates lose points — being 80% sure on four options and guessing on the fifth costs you the full question.
- Scenario length: Question stems on specialty exams are long. A typical Domain 1 question might describe a three-tier application with specific latency requirements, a compliance mandate, and an existing on-premises MPLS connection, then ask you to choose between four architecturally different solutions. You need to read fast and filter for the constraint that actually eliminates options.
- BGP depth: BGP-related questions appear consistently across ANS-C01 versions. Know AS_PATH prepending, BGP communities for Direct Connect, and how to influence traffic routing when you have both a Direct Connect and a VPN for the same destination prefix.
- Labs over reading: The questions that trip up book-only candidates are the operational ones — "VPC Flow Logs show dropped packets at the ENI but the security group allows the traffic; what's wrong?" That reasoning requires having actually seen NACLs interfere with stateless return traffic, not just having read that NACLs are stateless.
For scheduling, Pearson VUE offers both in-person and online proctored options. The exam fee is $300. AWS occasionally offers discounts through training credits or after sitting other exams — check your AWS Certification account for available benefits before paying full price.
Career Outcomes: What the AWS Certified Advanced Networking Specialty Actually Gets You
This cert sits in a narrow but genuinely valued position in the job market. It's not a volume credential like the Solutions Architect Associate — there are far fewer holders, and the technical bar is real enough that it carries weight in interviews and salary negotiations.
Roles that list ANS-C01 as preferred or required:
- Senior Network Engineer (Cloud): $130,000–$175,000 in the US. Responsible for designing and maintaining AWS networking infrastructure at an organization with significant cloud footprint.
- Cloud Architect: $145,000–$195,000. Networking specialty differentiates candidates when architects need to own hybrid connectivity decisions, not just hand them off to a networking team.
- DevOps / Platform Engineer: $130,000–$170,000. Less common, but organizations building internal developer platforms on AWS increasingly need engineers who can design secure network segmentation without slowing down teams.
- Consultant / Solutions Architect (AWS Partner): Variable, often higher than internal roles with billable-rate bonuses. AWS Partner Network firms actively value specialty certs for engagement eligibility and competency designations.
The cert does not meaningfully help in pure on-premises networking roles or in organizations with minimal AWS footprint. It's a career accelerant in cloud-native or cloud-heavy environments, not a general networking credential.
FAQ
How hard is the AWS Certified Advanced Networking Specialty compared to other AWS exams?
It's widely considered one of the two or three hardest AWS exams, alongside the Solutions Architect Professional and DevOps Engineer Professional. The difficulty is less about obscure facts and more about applying multiple networking concepts simultaneously in complex scenarios. Candidates with strong on-premises networking backgrounds but limited AWS exposure often find Domain 1 harder than expected; candidates with AWS experience but weak BGP/routing fundamentals struggle with Domain 2 questions involving Direct Connect.
What's the difference between ANS-C00 and ANS-C01?
ANS-C00 was the original exam version, retired in 2023. ANS-C01 added more emphasis on network automation (CloudFormation, CLI-based provisioning), Transit Gateway (which didn't exist when ANS-C00 launched), and AWS Network Firewall. If you're using older study materials, verify they cover Transit Gateway deeply and include Network Firewall — older guides that predate those services have meaningful gaps.
Is hands-on lab experience required to pass, or can you study from courses alone?
You can technically pass from courses and question banks alone if you're already an experienced network engineer who can mentally simulate how routing and stateful/stateless filtering behave. Most candidates who attempt this without hands-on practice fail the first attempt. The $300 retake cost and the time overhead make lab practice the more economical choice even if you're confident. AWS provides free labs through AWS Skill Builder for some networking topics.
How long should I study for the ANS-C01?
Candidates with an active AWS associate cert and a networking background typically take 8–12 weeks of part-time study. Candidates new to AWS but with deep on-premises networking experience should plan 12–16 weeks and include significant AWS hands-on time. People who've already been working daily in AWS networking roles report passing in 4–6 weeks of focused review. There's no shortcut that substitutes for actually knowing the material — this exam is difficult to bluff.
Does the AWS Certified Advanced Networking Specialty expire?
Yes. All AWS certifications are valid for three years. Recertification requires passing either the same exam or a higher-level exam that encompasses the domain (currently no higher-level exam covers networking specialty specifically, so recertification means retaking ANS-C01 or the current equivalent). AWS occasionally retires and replaces exam versions; monitor your certification expiry and the current exam code before scheduling a recertification attempt.
Is the cert worth it if I'm already working in AWS networking without it?
Depends on your goal. If you're at a company that values certifications in performance reviews or promotion criteria, yes. If you're job searching, the cert helps with recruiter filters and salary negotiation, particularly at AWS Partner organizations. If you're already senior and well-compensated at a company that cares about output over credentials, the ROI is lower — the knowledge from studying is still useful, but the cert itself may add less career leverage than at an earlier career stage.
Bottom Line
The AWS Certified Advanced Networking Specialty is a legitimate technical credential that reflects real expertise. It's worth pursuing if you're working in or moving into a role where AWS networking design is a significant part of the job, and if your target employers recognize it (most cloud-focused companies and AWS Partner organizations do). The ANS-C01 exam rewards people who've actually built and debugged AWS network architectures — studying alone without hands-on time produces candidates who pass with marginal scores and can't apply the knowledge in practice.
Start with the ANS-C01 dedicated course for structured coverage of all five domains, supplement with practice question sets focused on networking scenarios, and build lab time in a personal AWS account on Transit Gateway and Direct Connect Gateway configurations specifically — those topics have outsized representation in the exam and the highest career application value.
