What it validates, who it is written for, and the experience it assumes.
Beyond the written/multiple-choice exam, this certification also requires a separate hands-on lab (or practical) exam on live equipment. Practice here prepares the written qualifying exam — the lab itself needs real hands-on experience, not just study.
The CCIE Enterprise Infrastructure certification is Cisco's expert-level credential for network professionals who architect, deploy, and optimize complex enterprise network solutions. It validates deep technical knowledge across network infrastructure, software-defined networking, transport technologies, security, and automation, preparing you to lead in the design and operation of modern enterprise networks.
To earn this certification, you must pass two exams: a written core exam (350-401 ENCOR) and a hands-on lab exam (CCIE Enterprise Infrastructure Lab Exam v1.1). The core exam also earns you the Cisco Certified Specialist - Enterprise Core certification. The lab exam tests your ability to plan, design, operate, and optimize dual-stack (IPv4 and IPv6) solutions for complex enterprise networks, ensuring you have the practical skills to excel in real-world environments.
This certification is for senior network engineers, network architects, and technical leaders who design, deploy, operate, and optimize complex enterprise network infrastructures. It is ideal for professionals aiming for senior-level or leadership positions in enterprise networking. Candidates typically have five to seven years of experience with enterprise networking technologies and solutions, and are looking to validate their expert-level skills and advance their careers.
Cisco recommends five to seven years of experience designing, deploying, operating, and optimizing enterprise networking technologies and solutions before taking the exam. Designing and deploying complex enterprise network infrastructures; Operating and optimizing enterprise networks with a focus on performance and reliability; Implementing software-defined networking solutions, including SD-WAN and SD-Access; Integrating security and services into enterprise network solutions; Automating network tasks to improve efficiency and reduce operational overhead
Every domain and objective Cisco measures, with the weight they carry on the exam.

See how the coach worksThe written qualifying exam for this CCIE is 350-401 ENCOR, the same exam as CCNP Enterprise (350-401 ENCOR). Practice the full ENCOR question bank on its Examers page to prepare the written portion. The 8-hour hands-on lab exam is a separate, live-equipment exam that cannot be prepared with practice questions alone — it requires real lab experience.
CCIE Enterprise Infrastructure focuses on enterprise network infrastructure, including routing, switching, SD-WAN, and SD-Access. CCIE Enterprise Wireless focuses specifically on wireless networking solutions. Both are expert-level certifications within the Enterprise track.
No. Cisco states there are no formal prerequisites for this certification. However, candidates are recommended to have five to seven years of experience with enterprise networking technologies.
Yes. The lab exam is a hands-on exam that tests your ability to plan, design, operate, and optimize dual-stack solutions (IPv4 and IPv6) for complex enterprise networks.
Passing the 350-401 ENCOR core exam automatically earns you the Cisco Certified Specialist - Enterprise Core certification. This is a separate credential from the CCIE Enterprise Infrastructure.
Yes. Both the 350-401 ENCOR core exam and the CCIE Enterprise Infrastructure Lab Exam can be paid for using Cisco Learning Credits.
Potential roles include Network Architect, Business Services Architect, and Systems Engineer. These roles focus on designing, implementing, and optimizing enterprise network solutions.
Your certification is valid for three years. You can renew it by earning Continuing Education credits or by retaking the required exams before the certification expires.

In front of every objective the practice pages are already there, free and without an account. This is one objective, opened.
33 questions on this objective, five to a page. Every range above is a real page, open now, with no account.
The curriculum tells you what is on the exam. Proving you know it is a different job — and it is the one the closed-book run does.
The whole bank is open. 5 questions to a page, every answer explained, and a discussion thread on each one.
Every objective, and every page range, is a link — so you can pick up exactly where you left off.
Short enough to finish, long enough to matter.
Not only which one is right — why the others are wrong.
Ask, answer, and vote. Every question has its own thread.
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 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.

The look-alikes sit togetherThe pairs the exam tests are drawn side by side, so the difference is seen, not told.
Dual coding · PaivioYou 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.

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.

Where the exam is defined, scheduled and scored.
We link to them rather than repeat them, so nothing here goes stale behind them.
We build from the official skills outline, not from a summary of it — 21 objectives, 186 concepts written under them, and free questions against every one. When Cisco changes the outline, this page changes with it.
That is the only question worth answering the night before, and no link answers it. You answer it by taking the questions with the book closed, and seeing what comes back.
