Questions people ask
How does the 350-901 exam relate to the retired 200-901 DEVASC exam?
The 350-901 AUTOCOR exam is a higher-level core exam for the DevNet Professional certification, while 200-901 DEVASC is the Associate-level exam. Passing 350-901 can also be used towards recertification.
Do I need to earn the DevNet Associate certification before taking 350-901?
No, the DevNet Associate is not a mandatory prerequisite. However, it is recommended as a foundational step before pursuing the Professional-level certification.
Is there a hands-on lab component in the 350-901 exam?
The 350-901 exam is a written exam. It does not include a hands-on lab, but it tests practical knowledge of automation and programmability concepts.
What is the retake policy if I fail the 350-901 exam?
For most exams, you must wait 5 calendar days after the day of the exam before retaking it. For CCIE or CCDE written exams, the wait is 15 days. The 350-901 is a Professional-level exam, so the 5-day rule applies.
Can I use Cisco Learning Credits to pay for the 350-901 exam?
Yes, you can use Cisco Learning Credits to pay for the exam. You can redeem them for exam vouchers through Pearson VUE.
What job roles does the DevNet Professional certification map to?
It aligns with roles such as network automation engineer, DevOps engineer, and software developer focused on network programmability.
Can I recertify by passing a different exam?
Yes, you can recertify by passing any other certification exam at the same or higher level, or by earning Continuing Education (CE) credits.
Is the 350-901 exam available in countries outside the US?
Yes, the exam is available globally through Pearson VUE. Pricing may vary by country, and you should check Pearson VUE for local availability and currency.

3A discussion on each
Ask, answer, and vote. Every question has its own thread.
A question, and the idea behind it
Every question comes from a concept
These are not trivia. Each one is written against a concept in the book, so when you get one wrong there is somewhere to go and find out why.
The visual book
See it once. Carry it into the exam.
The pages shown here come from our AI-900 book — an example of how each concept is written in plain language and, where the idea needs one, drawn as a full page you can take in at a glance.

This is the part that teaches. The illustration and the written explanation stay where they are while you work, so a scenario stops being a memory test and becomes something you can simply look at.
It teaches · it does not count
A smartphone uses AI to unlock when the owner looks at the camera. Which AI capability is being used?
AImage classification
BFacial recognition
COptical character recognition
DObject detection
Look at the five steps. Detect finds a face, align straightens it, encode turns it into numbers, search compares it with a stored face, and decide answers one question: is this the same person? Classification would only say “a face”. Detection would only draw a box. Neither decides whose.
Then the page shuts, and it starts counting
The same questions come back with the book closed — that run is the one that counts. After it, your coach picks one thing for tonight, sized to the time you have, and brings pages back before you lose them.
