AWS Advanced Networking Specialty (ANS-C01): Official Exam Format, Cost, and Why It's Rated Like a Professional-Level Exam

What ANS-C01 Certification Actually Certifies

This is AWS's most technically demanding networking-focused credential, and AWS's own exam guide is direct about its scope: the exam validates a candidate's ability to design, implement, manage, and secure AWS and hybrid network architectures at scale. That last phrase — "at scale" — is doing  work; this isn't testing whether you can stand up a single VPC. AWS's stated task domains include designing and developing hybrid and cloud-based networking solutions, implementing core AWS networking services according to best practices, operating and maintaining that infrastructure long-term, and using automation tooling to deploy and manage networking tasks at production scale.

Multiple independent prep resources consistently describe this exam as comparable in difficulty to AWS's Professional-level certifications (like Solutions Architect Professional), even though it's formally classified in AWS's Specialty tier. That comparison is worth taking seriously if you're weighing whether you're ready — this isn't a credential to approach the way you might an Associate-level exam.

Who ANS-C01 Exam Is For (and Who It's Not For)

There's no formal prerequisite, but AWS's recommended background is substantial: 5 years of networking experience, including 2 or more years of cloud and hybrid networking experience specifically. This exam assumes genuine depth with both traditional networking concepts (BGP routing, DNS architecture, hybrid connectivity design) and AWS-specific networking services working together, not one or the other in isolation.

It's a strong fit for network engineers and architects who already hold AWS Associate-level certification (commonly Solutions Architect Associate or SysOps Administrator Associate) and have  hands-on experience designing multi-account, multi-region VPC architectures, hybrid connectivity via Direct Connect and VPN, and network automation through infrastructure as code. It's a poor entry point for anyone without that combined traditional-networking-plus-AWS foundation — attempting this exam without both halves of that background is a commonly cited reason candidates fail despite general AWS familiarity.

Exam Format and Structure

The exam consists of 65 questions — a mix of multiple choice and multiple response — delivered over 170 minutes. Unanswered questions are scored as incorrect, and there's no penalty for guessing, so leaving anything blank is a pure loss with no strategic upside.

The pacing itself (170 minutes for 65 questions, roughly 2.6 minutes per question) is generous by AWS Specialty-exam standards, and that's intentional — it allows  time to read, analyze, and work through the complex, scenario-based networking architectures the exam relies on rather than testing pure speed. The trade-off is that the questions themselves tend to be dense: multi-part scenarios describing existing hybrid or multi-region architectures where you need to identify the correct next step or fix, rather than straightforward single-fact recall.

Domains and Topics Covered

AWS's official exam guide specifies four content domains and their exact weightings:

Network Design carries the largest share and centers on architecting solutions using services like Amazon CloudFront, AWS Global Accelerator, and Amazon Route 53 for traffic management and DNS, alongside the core VPC design patterns (multi-account, multi-region) that underpin most of the exam's scenario-based questions. Network Implementation and Network Security together account for exactly half the exam, with hybrid connectivity — AWS Direct Connect and VPN-based solutions specifically — recurring as a theme across multiple domains rather than being confined to just one.

AWS's exam guide is explicit that understanding which specific AWS services are in scope versus out of scope is worth checking directly against the current guide before studying, since the guide maintains separate detailed lists of covered services — treating a general AWS networking familiarity as sufficient without confirming the exact service list is a common and avoidable gap in preparation.

Cost Breakdown

The exam costs $300 USD, consistent with AWS's standard pricing for Specialty-tier certifications (the same tier as other AWS Specialty exams). Pricing may vary slightly depending on your proctoring location and applicable local taxes. One cost-saving detail worth knowing: AWS commonly issues a 50% discount voucher to candidates who've already passed a prior AWS certification, which can meaningfully reduce the cost of this exam if you're building on an existing AWS credential — worth checking your AWS certification account for an available voucher before paying full price.

Prerequisites and Eligibility

None are formally enforced — anyone can register and sit the exam regardless of documented experience. AWS's recommended background (5 years networking experience, 2+ years specifically in cloud and hybrid networking) functions as genuine informal guidance rather than a registration gate, but given how consistently prep resources describe this exam's Professional-level difficulty, attempting it without that world foundation is a considerably higher-risk approach here than for AWS's Associate-level or Foundational exams.

How ANS-C01 Exam Is Scored and What Passing Requires

You need a scaled score of 750 out of a possible 1,000. AWS uses a compensatory scoring model here, consistent with its other certifications covered elsewhere on this site — you only need to pass the overall exam score, not each individual domain separately, so relative weakness in one domain can be offset by strength elsewhere, provided your overall score clears 750.

Renewal and Recertification

This certification is valid for 3 years, matching AWS's standard recertification cycle across its certification catalog. You can recertify either by passing the current version of the ANS-C01 exam again, or by passing a higher-level AWS exam — though since Advanced Networking Specialty sits at AWS's most senior specialty tier for networking specifically, there isn't a more advanced networking-focused AWS credential above it the way ML Engineer Associate sits above AI Practitioner in AWS's AI track (covered elsewhere on this site). In practice, most ANS-C01 holders recertify by retaking the current version of this same exam.

How ANS-C01 Exam Compares to Its Closest Alternative

Within AWS's own certification catalog, there isn't a direct networking-focused competitor at the same depth — this is AWS's flagship networking specialty credential, and the closer internal comparison is against AWS's Solutions Architect Professional certification, which several prep resources note as a comparable difficulty benchmark even though the two validate different specific skill sets (broad multi-service architecture versus deep networking specialization).

Outside AWS, the closest cross-vendor comparisons are vendor-specific networking credentials from other cloud providers, or traditional networking certifications like Cisco's CCNP or CCIE (covered elsewhere on this site for the associate-level CCNA). The practical distinction is significant: Cisco's advanced networking credentials test deep, vendor-specific on-premises and hybrid networking implementation broadly, while ANS-C01 tests that same depth of networking judgment specifically applied to AWS's cloud-native and hybrid networking services. A network engineer with strong traditional Cisco-side networking experience moving into cloud-heavy hybrid architecture work is a common and well-suited candidate profile for this specific AWS credential.

 Preparation Timeline

Given the exam's  Professional-level difficulty, a commonly cited preparation window is 3 to 6 months after already holding an AWS Associate-level certification, with the exact timeline depending heavily on how much hands-on experience you already have with both traditional networking concepts and AWS-specific networking services combined. This is a meaningfully longer runway than most Associate-level AWS certifications require.

Preparation resources consistently emphasize mandatory hands-on labs focused specifically on hybrid connectivity and complex routing scenarios, not just reading AWS whitepapers — the exam's scenario-based question style rewards genuine applied troubleshooting experience over memorized service descriptions. A commonly repeated benchmark before scheduling the  exam: consistently scoring 80% or higher across full-length, timed practice exams (65 questions, 170 minutes, no breaks) under  conditions, rather than scheduling as soon as material feels generally familiar.
