Let's do the arithmetic properly, because "is it worth it" articles almost never actually add anything up. The 350-901 exam cost 2026 is $400 USD, and that's just the line item on the receipt. The real number is bigger and the decision depends on which of three people you are.
Also: the exam changed names this year, and if you're reading a study plan written in 2025 you may not know that yet.
The rename, first
Effective 3 February 2026, Cisco updated 350-901 to v2.0 and renamed it from DEVCOR (Developing Applications using Cisco Core Platforms and APIs) to AUTOCOR — Designing, Deploying, and Managing Network Automation Systems.
Same exam code. Same 120 minutes. Same $400. Different centre of gravity.
DEVCOR was a software-engineering exam that happened to use Cisco APIs. AUTOCOR v2.0 pulls the focus toward network automation systems specifically — designing them, deploying them, operating them. The API work is still there, the Python is still there, but the framing moved from "you are a developer touching network gear" to "you are automating a network estate."
If you started studying under the DEVCOR blueprint, most of your work carries over. Pull the current AUTOCOR v2.0 exam topics from the Cisco Learning Network and diff it against what you've covered. Don't assume.
The full cost, honestly
Exam fee: $400 USD. That's the concurrent professional-level price.
Retake: another $400, after a mandatory waiting period. Cisco's professional exams have a real failure rate, so budget mentally for a 1.3x multiplier unless you're already doing this work daily.
Training, if you buy it: Cisco's official AUTOCOR course runs into the thousands through a learning partner. The official cert guide is around $80–$150 depending on bundle. Cisco U. subscriptions sit in the few-hundred-per-year range.
Time: this is the number people leave out and it dominates everything. Realistically 120–200 hours if you're a network engineer who codes a bit, 80–120 if you're already writing automation in production, 250+ if you're coming from pure networking with no Python.
At even a conservative $40/hour valuation of your own evenings, 150 hours is $6,000 of life. The $400 is a rounding error. Decide on the time, not the fee.
And the concurrent part: 350-901 alone doesn't give you the DevNet Professional certification. You need the core exam plus a concentration exam. So the actual certification cost is $400 plus a concentration exam fee (typically $300), so roughly $700 in exam fees for the badge.
Who it pays off for
The network engineer who's tired of the CLI. This is the highest-return group by a distance. You already know why a change window exists and what breaks. Adding real automation skill — Python, REST, YANG/NETCONF/RESTCONF, CI/CD for network config, model-driven telemetry — moves you from "person who types commands" to "person who builds the thing that types commands." That transition is where the salary step change lives, typically a solid move up from senior network engineer into network automation or platform roles.
The consultant who bills on credibility. Cisco professional-level certs still open doors in enterprise and partner channels. If a certification changes which projects you're staffed on, $400 is trivially worth it.
The software developer curious about networking. Weakest case. You'll find the Python easy and the network domain knowledge unexpectedly deep, and the badge won't mean much in a software hiring loop. Unless you specifically want to work in network automation, spend the 150 hours elsewhere.
What the exam actually covers
Roughly, and read the current topics yourself:
- Software development and design — design patterns, modular design, APIs, versioning, database selection, sequence diagrams. Around a quarter of the exam and more theoretical than people expect.
- Using APIs — REST fundamentals, rate limiting, pagination, error handling, authentication (OAuth2, tokens), webhooks, and how to consume Cisco platform APIs sensibly.
- Cisco platforms — the breadth killer. Meraki, DNA Center/Catalyst Center, ACI, NX-OS, IOS-XE, Webex, Firepower/FMC, Intersight, UCS. You don't need mastery of each, but you need to know which platform solves which stated problem and roughly what its API looks like.
- Application deployment and security — containers, CI/CD pipelines, secrets management, OWASP-shaped concerns, logging and observability for deployed apps.
- Infrastructure and automation — the AUTOCOR heart. NETCONF, RESTCONF, YANG models, model-driven telemetry, Ansible and Terraform against network devices, configuration drift, zero-touch provisioning.
The breadth is the difficulty. Individual questions are fair; the surface area is enormous.
How I'd sequence 12 weeks
Weeks 1–3: Python for real. Requests, error handling, virtual environments, writing something that consumes a paginated API and handles a 429. If you can't do that from memory, don't move on.
Weeks 4–6: APIs and platforms. Get free sandbox access on Cisco DevNet — it's genuinely free and it's the single best resource for this exam. Hit Meraki's dashboard API, Catalyst Center's intent API, and NX-OS via RESTCONF. Actually make calls.
Weeks 7–9: Automation core. NETCONF and RESTCONF against a sandbox device, read a YANG model without panicking, set up telemetry, write an Ansible playbook that configures an interface.
Weeks 10–11: Deployment and security. Containerise something. Build a pipeline that lints and tests network config.
Week 12: Questions and gap-filling.
Start practice questions around week 6, not week 12. The exam's phrasing teaches you what depth Cisco expects per platform, and that recalibrates the rest of your study. I ran free 350-901 practice questions mid-way through and immediately discovered I'd been going far too deep on Meraki and nowhere near deep enough on YANG.
For the final grind, ExamCert is what I used for the volume — a few dollars for lifetime access, which for a $400 exam with a 12-week runway is not the place to be economising or over-spending. Whatever you use, read the explanations. On a breadth exam, the explanation for a question about a platform you've never touched is worth more than the question itself.
The verdict
$400 for the exam, ~$700 for the full certification, and 150 hours of your life.
If you're a network engineer moving toward automation, that's one of the better returns available in the Cisco catalogue right now, and the AUTOCOR rename makes the badge more legible to hiring managers than "DEVCOR" ever was. Network automation is the thing enterprises are actually hiring for.
If you're anything else, the maths gets thin fast.
Check the v2.0 topics before you book. Use the DevNet sandboxes. And decide based on the 150 hours, not the $400.
