AWS Advanced Networking Specialty Exam Preparation Guide

There is a deadline attached to this exam, and it should shape your entire study plan: AWS has scheduled the Certified Advanced Networking – Specialty certification for retirement, with 31 December 2026 as the last day the ANS-C01 exam can be taken. No successor exam had been announced as of August 2026. If you earn the credential before the cut-off it remains active for the standard three years — so for network engineers who want AWS's deepest networking validation on their record, the question is no longer whether to prepare but how efficiently. This guide lays out a preparation approach for ANS-C01's hybrid-networking core — Direct Connect, Transit Gateway, DNS and the design trade-offs between them — built for people working against that calendar.

For the exam's full logistics — registration, languages, formal blueprint — see the AWS Advanced Networking Specialty certification guide; this article concentrates on study strategy. And if you are weighing this specialty against a broader credential, the AWS certification roadmap for 2026 covers sequencing across the whole portfolio in one place.

Exam parameters that shape your preparation

Four facts about ANS-C01, all current as of 2026, determine how you should study:

• 65 questions in 170 minutes, multiple choice and multiple response. That is a more generous per-question budget than most AWS exams — roughly two and a half minutes each — because networking scenarios demand careful reading of topologies described in prose.
• $300 USD (regional pricing and taxes vary; confirm on AWS's exam pricing page), with a scaled passing score of 750 out of 1000. The scaled score is not a percentage; AWS publishes no pass rates.
• No prerequisites. AWS recommends five or more years of networking experience with two or more years in cloud or hybrid environments — a signal of the assumed depth, not a gate. Nothing formally requires an associate certification first.
• Specialty renewal rules are strict. Unlike associate certs, which higher-level exams can renew, a specialty is only renewed by retaking the current specialty exam. With ANS-C01 retiring and no successor named, a certification earned in 2026 will simply expire three years on unless AWS announces a replacement path — worth knowing before you invest the study time, though it does not diminish what the credential says about you while active.

Delivery is through Pearson VUE, at a test centre or online proctored, so the retirement deadline is about booking availability, not geography.

Start from the exam guide, then think like the exam does

Download the official ANS-C01 exam guide from AWS's certification page and treat its domain list and weightings as your syllabus — this article deliberately does not paraphrase them, because the guide is authoritative and free. What the guide cannot tell you, and what this section can, is the mindset the questions reward.

ANS-C01 is a specialist's exam in the truest sense: it assumes you already think in routing tables, BGP path selection and failure domains, and it tests whether you can express that thinking through AWS's constructs. Questions describe hybrid topologies — corporate data centres, multiple VPCs, multiple Regions, sometimes multiple AWS accounts — and ask you to achieve a connectivity, resilience, performance or cost goal. The wrong options are rarely nonsense; they are designs a competent engineer might build that fail one stated requirement, often quietly.

That means your preparation should constantly ask three questions of every AWS networking construct you study:

1. What are its limits? Scale boundaries, bandwidth characteristics and attachment models decide many questions.
2. How does it fail, and what does failover look like? Resilience requirements are the most common hidden constraint in networking scenarios.
3. What does it cost relative to the alternatives? Several questions turn on choosing the cheapest design that still meets requirements, or the highest-bandwidth option within a budget.

A pillar-by-pillar study approach

Rather than working through a course linearly, organise your preparation around the technical pillars that hybrid AWS networking is actually built from. For each pillar: read the AWS documentation's concepts pages, build what you can in a lab account, and write a one-page decision summary in your own words.

Pillar 1: Hybrid connectivity — Direct Connect and VPN

This is the heart of the exam's hybrid focus. You should be able to reason fluently about when a dedicated physical connection is justified over VPN, how the two combine for resilience, and how routing behaves across those boundaries — including how BGP attributes influence path selection between redundant links. Lab reality check: most candidates cannot provision a real Direct Connect circuit for study, and that is fine. You can still build and dismantle site-to-site VPNs, inspect the routing behaviour, and study Direct Connect through AWS's documentation and published resiliency recommendations. Write out failover narratives by hand: "primary link down — what happens, in what order, and what does the customer notice?"

Pillar 2: Inter-VPC and inter-network architecture — Transit Gateway and friends

Modern multi-VPC estates route through hub-and-spoke designs, and the exam expects you to know when a hub is the right answer versus simpler point-to-point alternatives — and what happens to routing, segmentation and bandwidth as the estate grows. This pillar is eminently lab-able: creating several small VPCs, attaching them to a Transit Gateway, and experimenting with route-table segmentation costs little and teaches more than any video. Pay particular attention to how designs extend across Regions and accounts, because scenario questions favour exactly those messy, realistic estates.

Pillar 3: DNS and traffic management

Hybrid DNS is a classic stumbling block: resolution needs to flow both ways between on-premises resolvers and AWS-hosted zones, and questions probe whether you know how to wire that up and troubleshoot it when described symptoms point to a resolution failure. Study private and public hosted zone behaviour, conditional forwarding patterns between corporate DNS and the cloud, and how DNS-based routing policies interact with health checks for failover designs. In your lab, break name resolution deliberately and diagnose it — the exam's troubleshooting questions read like tickets, and ticket instinct is trainable.

Pillar 4: Network security and edge

Expect security to be woven through scenarios rather than quarantined in its own questions: segmenting traffic, inspecting it centrally, exposing services privately rather than over the public internet, and terminating TLS in the right place. Focus on where in a topology each control belongs and what traffic each one can and cannot see. (If your interest is security-first rather than network-first, note that AWS maintains a dedicated Security – Specialty certification — its scope is covered in the AWS Security Specialty certification guide — and it is not retiring.)

Pillar 5: Monitoring, logging and network operations

The unglamorous pillar that decides marginal passes. Know how to capture and read flow-level telemetry, how to trace why a packet was dropped, and which tool answers which operational question. When a scenario says "the team needs to identify which security rule is blocking traffic", the answer is usually a specific capability, and candidates who have only built networks — never operated them — miss these marks.
