About this certification
The CCNP Enterprise certification is a professional-level credential that proves your skills in implementing and operating core enterprise network technologies. It covers dual-stack (IPv4 and IPv6) architecture, virtualization, infrastructure, network assurance, security, and automation. This certification is ideal for network engineers who are ready to move beyond associate-level knowledge and take on more complex network design and troubleshooting responsibilities.
To earn the CCNP Enterprise, you must pass the 350-401 ENCOR core exam and one concentration exam of your choice. The ENCOR exam also counts toward the CCIE Enterprise Infrastructure and CCIE Enterprise Wireless certifications, making it a versatile step in your Cisco certification journey. With this credential, you demonstrate that you can handle the demands of modern enterprise networks, from automation to security.
Who it’s for
This certification is for network engineers, network administrators, and IT professionals who are responsible for implementing and managing enterprise network solutions. It is also suitable for those who want to specialize in enterprise networking and advance their careers to a professional level. Candidates typically have several years of experience with Cisco networking technologies and are familiar with routing, switching, and network security concepts. They are comfortable working with command-line interfaces and have a solid understanding of network architecture.
Recommended experience
Cisco recommends that candidates have a good understanding of enterprise networking fundamentals, including routing and switching, as well as some experience with network automation and security. Hands-on experience with Cisco routers and switches; Knowledge of routing protocols such as OSPF and EIGRP; Familiarity with network security concepts and VPN technologies; Basic understanding of network automation and programmability

What a practice page gives you
1Five to a page
Short enough to finish, long enough to matter.
2Every answer explained
Not only which one is right — why the others are wrong.
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.

Why a picture, and not another paragraph
Three reasons, and each one is a real finding rather than a slogan.

You are never asked to read a poster here — only to see how one is built. After that, every other page is legible at a glance.

Open book, on purpose
Answer it with the picture beside you
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.
