- No formal prerequisites exist; CCNA is recommended, not required, since 2020.
- You need two exams: 350-401 ENCOR ($400, 120 minutes) plus one $300 concentration exam.
- Each passed exam is valid three years, so both must be passed inside that window to earn the certification.
- Passing ENCOR alone earns Cisco Certified Specialist - Enterprise Core and satisfies CCIE Enterprise Infrastructure/Wireless qualification.
Quick Answer: What Cisco Actually Requires
Cisco Certified Network Professional Enterprise has fewer gatekeeping requirements than most candidates expect. There is no application form, no employer sponsorship, and no mandatory prior certification. What Cisco does require is that you pass two specific exams delivered through Pearson VUE: the core exam 350-401 ENCOR and one concentration exam of your choosing. Everything else - CCNA, years of experience, formal training - is guidance, not gatekeeping.
That distinction matters because it changes how you plan. Instead of asking "am I allowed to sit this exam," the real question becomes "am I ready for the six domains ENCOR actually tests." This article walks through every eligibility mechanic - prerequisites, fees, timing windows, and renewal - so you can qualify with confidence rather than guesswork.
Formal Prerequisites (There Aren't Many)
Cisco removed formal prerequisites from its certification track in 2020. That means there is no requirement to hold CCNA, no minimum job title, and no proof-of-experience document you submit before registering. You can register for ENCOR the same day you decide to pursue the certification, provided you're prepared for the material.
If you're unsure whether you meet the practical bar (as opposed to the paperwork bar), the honest self-check is whether you can already configure and troubleshoot VLANs, trunking, and basic routing without reference material. If not, closing that gap before booking ENCOR is far more valuable than any formal prerequisite would be.
The Two-Exam Requirement
Qualifying for CCNP Enterprise means passing exactly two exams:
- 350-401 ENCOR (Implementing Cisco Enterprise Network Core Technologies) - $400 USD, 120 minutes, the required core exam for everyone.
- One concentration exam - $300 USD, 90 minutes, chosen from six options covering advanced routing, SD-WAN, network design, automation, cloud connectivity, or network assurance.
Both exams are delivered in English and Japanese, at a Pearson VUE test center or via online proctoring. Cisco does not publish a fixed number of questions or a fixed passing score; forms commonly deliver 90 to 110 items, and all current CCNP exams mix multiple-choice questions with performance-based lab items. For a full breakdown of what "passing" actually requires numerically, see the CCNP Enterprise passing score guide.
Key Takeaway
You do not have to pass both exams on the same day or in a fixed order - but you do have to pass both inside the three-year validity window of the first one you pass, or the earlier exam expires before the certification is granted.
Recommended Experience and Knowledge Baseline
Cisco suggests three to five years of experience implementing enterprise networking solutions before attempting ENCOR. That's a guideline, not a checkpoint - nobody verifies it at registration. In practice, it reflects the depth of the Infrastructure domain, which at 30% is the single heaviest topic area on the exam and covers real operational skills:
Infrastructure (30%) - The Experience-Dependent Domain
This is where hands-on time shows. Candidates without production experience often underestimate how much muscle memory these topics require.
- 802.1Q trunking and EtherChannel troubleshooting
- RSTP and MST spanning-tree behavior
- OSPFv2/OSPFv3 and EIGRP comparison
- eBGP between directly connected neighbors
- NAT/PAT, HSRP and VRRP, NTP/PTP, and multicast
If your day job doesn't touch BGP peering or multicast design, you can still qualify - but you'll need lab repetition to substitute for the missing field experience. Our CCNP Enterprise study guide breaks down how to sequence that practice against the exam blueprint.
Registration and Fee Mechanics
Registration happens through Pearson VUE, either at a physical test center or via online proctoring. Fees are fixed by Cisco per exam, not bundled:
| Exam | Role | Fee (USD) | Duration |
|---|---|---|---|
| 350-401 ENCOR | Required core exam | $400 | 120 minutes |
| Concentration exam (choose one) | Required, six options available | $300 | 90 minutes |
Total cost to qualify is the sum of both fees, with no bundling discount published in Cisco's blueprint materials. For a complete accounting of registration, retake, and training costs, see the CCNP Enterprise certification cost breakdown. You can compare available testing windows and blackout considerations in the exam dates and scheduling guide before you lock in a date.
Timing Rules: Certification Validity Windows
This is the eligibility detail most candidates overlook. Each passed professional-level exam - ENCOR and the concentration exam - is individually valid for three years from the pass date. To actually earn CCNP Enterprise, both exams must be passed inside that rolling window.
Once both exams are complete, the certification itself is valid for three years from the date it's awarded - a separate clock from the individual exam windows.
The Domain Blueprint Behind Eligibility
Eligibility isn't just administrative - it's content-based. ENCOR v1.2, effective March 19, 2026, tests six domains, and understanding their weighting tells you where to concentrate preparation time before you're truly "ready" to qualify:
Architecture - 15%
Enterprise network design principles, hybrid cloud connectivity, and structured design models.
Virtualization - 10%
Virtual network components, network functions virtualization, and virtualization concepts relevant to enterprise infrastructure.
Infrastructure - 30%
The heaviest domain; covers switching, routing, first-hop redundancy, NAT, and multicast as detailed above.
Network Assurance - 10%
Monitoring and troubleshooting tools, now including Cisco Catalyst Center AI-powered workflows folded in under v1.2.
Security - 20%
Raised from prior weighting under v1.2; covers device hardening, access control, and network security design principles.
Automation and Artificial Intelligence - 15%
Renamed under v1.2 to reflect AI-assisted automation content alongside traditional programmability topics.
Notice that wireless topics were removed from this blueprint under v1.2 and shifted to the wireless specialty track - a change worth knowing if you're studying from older material. For a domain-by-domain study approach, the exam domains guide goes deeper into each area, and this difficulty breakdown explains how the performance-based items change the exam experience compared to pure multiple-choice testing.
Choosing Your Concentration Exam
Part of qualifying is picking the right second exam. All six options are $300 and 90 minutes, but they lead in very different directions:
| Concentration Exam | Focus Area |
|---|---|
| 300-410 ENARSI | Advanced routing and services - deep dive on IGP/BGP scaling and infrastructure services |
| 300-415 ENSDWI | Cisco SD-WAN implementation and operation |
| 300-420 ENSLD | Enterprise network design principles |
| 300-435 ENAUTO | Automating and programming Cisco enterprise solutions |
| 300-440 ENCC | Enterprise cloud connectivity |
| 300-445 ENNA | Enterprise network assurance |
Pick the exam that matches the role you're aiming for, not the one that seems easiest. If you're targeting a design-heavy or automation-heavy team, browse CCNP Enterprise job listings for the specific tools and platforms employers mention - that's a faster signal than guessing from exam titles alone.
Staying Certified: Renewal Requirements
Qualifying once isn't permanent. CCNP Enterprise is valid for three years from the award date, and renewal happens one of three ways:
- Earning 80 continuing education credits within the three-year cycle
- Passing qualifying exams before the cycle ends
- A combination of continuing education credits and exams
Notably, passing ENCOR by itself also earns the Cisco Certified Specialist - Enterprise Core credential and satisfies the qualifying requirement for CCIE Enterprise Infrastructure and CCIE Enterprise Wireless lab attempts - a useful side benefit if your longer-term goal is expert-level certification. If you're weighing whether the ongoing renewal commitment is worthwhile relative to career impact, see our ROI analysis of CCNP Enterprise.
A Realistic Qualification Timeline
Because eligibility here is really about readiness rather than paperwork, the most useful way to "qualify" is to build a study sequence that respects domain weighting. Here's a template built around ENCOR's blueprint:
Infrastructure foundations
- Trunking, EtherChannel, RSTP/MST
- OSPFv2/v3 and EIGRP comparison labs
- eBGP between directly connected neighbors
Security and Network Assurance
- Device hardening and access control design
- Catalyst Center-driven assurance workflows
Architecture and Virtualization
- Enterprise design models and virtual network components
Automation and Artificial Intelligence
- Programmability fundamentals and AI-assisted automation concepts
Concentration exam prep
- Deep-dive on your chosen concentration topic area
Run practice exams under timed conditions throughout - not just at the end - using a tool like our CCNP Enterprise practice test platform to simulate the mix of multiple-choice and performance-based items you'll actually face. A dedicated practice-question routine on the main practice site is also the fastest way to spot which of the six domains still need work before you book a date.
