Cisco 350-401 ENCOR (CCNP Enterprise Core): What's Actually Tested

The Cisco 350-401 ENCOR (Implementing and Operating Cisco Enterprise Network

Core Technologies) is the core exam for CCNP Enterprise and doubles as the

written qualifying exam for CCIE Enterprise Infrastructure and CCIE Enterprise

Wireless. The exam costs $400, runs 120 minutes, has 90 to 110 questions, and

requires a score of around 825 out of 1000 to pass. Cisco does not publish an

official cut score, but that figure reflects consistent community consensus.

Most experienced engineers need 10 to 14 weeks of focused study. The question

mix is heavily scenario-based multiple choice and drag-and-drop, with far fewer

hands-on simulations than CCNA. If you hold a CCNA and have worked in

enterprise networks, this is the next logical credential. If you are brand new

to Cisco gear, start with CCNA first.

The 90-second answer

Take 350-401 ENCOR if you are an experienced network engineer who wants

to advance from CCNA to CCNP, or if your role already involves enterprise

routing, switching, wireless, SD-WAN, or SD-Access. ENCOR is also the

required qualifier if you are eventually targeting a CCIE lab. The credential

is widely recognized by enterprise employers and represents a real knowledge

step up from associate-level certs.

Skip 350-401 ENCOR if you have not yet passed CCNA 200-301 or built

genuine hands-on networking experience. There are no formal prerequisites,

but Cisco recommends three to five years of enterprise networking experience,

and that recommendation reflects the actual question difficulty. Going in

underprepared costs $400 for the first attempt and $400 again for the

retake, with a five-day wait between attempts.

What does the 350-401 actually test?

ENCOR covers six domains. The current blueprint is version 1.1. Every

question maps to one of these.

Infrastructure carries the highest weight at 30%, so routing protocol depth

matters more here than on any other Cisco exam below the CCIE. You need to

understand OSPF neighbor adjacencies, BGP path selection, EIGRP metric

calculation, and STP root bridge election, not just recognize the terms.

The Architecture and Automation domains together are 30% of the exam and they

reward candidates who have worked with modern enterprise designs. SD-WAN and

SD-Access questions describe a fabric or a deployment scenario and ask you to

identify the correct component, design decision, or troubleshooting step.

These are not conceptual-only questions. You need to know how SD-WAN control

plane, data plane, and management plane separate, and where Cisco DNA Center

fits in SD-Access fabric design.

The Security domain at 20% is broader than most candidates expect. AAA using

TACACS+ versus RADIUS is a common topic, as is CoPP (Control Plane Policing),

which protects the router control plane itself. 802.1X and MACsec appear in

scenario questions that mix wireless and wired access.

Automation at 15% is not optional studying. Community feedback from recent

exam sittings consistently flags Python, REST APIs, and YANG data models as

live on exam day. You do not need to write production Python, but you do need

to read a short script and understand what it does, parse a JSON payload, and

describe how a RESTCONF or NETCONF call is structured.

How hard is the 350-401?

ENCOR is a difficulty 4 out of 5. Clearly harder than CCNA 200-301, which is

a 3.5, and significantly broader in scope. Cisco does not publish a pass rate,

but community surveys suggest first-time pass rates are lower than CCNA,

largely because the breadth and depth of six domains is genuinely demanding

even for working engineers.

The hard parts are specific:

• The Infrastructure domain alone is 30% of the exam and it expects depth
  on three routing protocols plus wireless and QoS, not just awareness of them


• SD-WAN and SD-Access are tested at a design and troubleshooting level that
  many engineers have not encountered in day-to-day operations, especially
  those in shops that have not deployed Viptela or Catalyst Center


• Automation questions require you to read and reason about code, JSON, and
  API calls even if you are not primarily a programmer


• No back button. Cisco exams lock each question on submission, so a
  scenario you get stuck on burns time you cannot recover


• At 90 to 110 questions in 120 minutes, you average just over one minute
  per question. Scenario-based items that require you to work through a
  multi-step design problem will consume two to three minutes each if you
  are not prepared

The most common failure pattern is candidates who know routing and switching

well but underestimate the Architecture and Automation domains. Solid OSPF

and BGP knowledge is necessary but not sufficient. Someone who scored well

on CCNA by memorizing show commands and protocol theory will struggle with

ENCOR's SD-WAN design and Python-parsing questions.

How long should you study for 350-401?

Cisco recommends three to five years of enterprise networking experience before

sitting the exam. That is not a suggestion to ignore. For actual study time:

• 
  With 3+ years enterprise networking and CCNP-level exposure at work:
  8 to 10 weeks at 10 to 15 hours per week


• 
  With CCNA and 1 to 3 years networking experience: 12 to 14 weeks at
  10 to 15 hours per week


• 
  With CCNA and less than one year of hands-on work: 16 to 20 weeks,
  and seriously consider accumulating more lab and production experience
  before booking


• 
  Coming from a different vendor or role type (Juniper, cloud, security):
  12 to 16 weeks to ramp on Cisco-specific implementations of shared concepts

A realistic week-by-week pace for a 12-week plan looks like:

1. Week 1: Enterprise architecture fundamentals, high availability designs,
   SD-WAN overview (Architecture domain foundation)


2. Week 2: SD-Access fabric design, overlay and underlay, Catalyst Center
   role


3. Week 3: Virtualization - VRF, GRE, IPsec, LISP, VXLAN concepts and use
   cases


4. Week 4: Layer 2 deep dive - VLANs, trunking, EtherChannel, STP variants


5. Week 5: OSPF areas, LSA types, neighbor adjacency troubleshooting


6. Week 6: EIGRP metrics and tuning, BGP path selection, route
   redistribution


7. Week 7: Wireless - AP modes, WLC architecture, roaming, wireless security


8. Week 8: IP services - QoS, NTP, NAT, DHCP, IP SLA


9. Week 9: Security - AAA, TACACS+ vs RADIUS, CoPP, 802.1X, MACsec, ACLs


10. Week 10: Network Assurance - SNMP, NetFlow, SPAN, DNA Center assurance,
    debug and show command strategy


11. Week 11: Automation - Python basics, JSON, REST APIs, YANG, DNA Center
    APIs, Ansible fundamentals, EEM


12. Week 12: Full timed practice exams, review weak domains, scenario
    drilling

The biggest waste of study time on ENCOR is focusing almost exclusively on

Infrastructure and ignoring Automation and Architecture. Many experienced

engineers come in strong on routing and switching, then get blindsided by

SD-WAN design questions and Python-parsing items that together account for

nearly a third of the exam.

What does the 350-401 cost?

The exam itself is $400 USD plus any local taxes. That is $100 more than CCNA,

and Cisco does not routinely issue discounted retake vouchers, so a failed

attempt means another $400 after the mandatory five-day wait.

Given the $400 per-attempt cost, the "do not book until your practice scores

are consistently above 80%" rule matters more here than on almost any other

associate or professional cert. Cisco occasionally runs promotional pricing or

partner voucher bundles through the Cisco Learning Network Store, so check

before you buy.

What salary can you expect after passing?

CCNP-level credentials move you from entry-to-mid into mid-to-senior

compensation territory. ENCOR alone qualifies you for CCNP Enterprise once

you add a concentration exam, and that combination is a recognized signal

for senior-level roles. 2026 US estimates from job boards:

• 
  Network Engineer with CCNP Enterprise: $95,000 to $130,000


• 
  Senior Network Engineer or Network Architect with CCNP: $130,000 to
  $175,000


• 
  Network Operations lead or consultant with CCNP: $100,000 to $145,000

CCNP holders in enterprise networking consistently out-earn CCNA-only

candidates by a meaningful margin. The gap widens further once CCNP is

combined with three or more years of production enterprise experience. At the

CCIE level, which ENCOR partially qualifies you for, total compensation

packages regularly exceed $175,000 in major markets.

The cert itself is the signal that gets you past resume filters for senior

network engineer and architect roles. The real pay trajectory requires the

cert plus actual work delivering SD-WAN rollouts, BGP policy changes, or

wireless infrastructure at scale.

What study resources actually work?

The candidates who pass ENCOR on the first attempt tend to use a consistent

stack:

1. 
   One structured course for breadth. Cisco Press's Official Cert Guide
   is the most thorough single resource; INE and CBT Nuggets both have video
   courses that are strong on the Infrastructure and Automation domains


2. 
   A real lab, not just Packet Tracer. ENCOR covers IOS-XE behaviors,
   SD-WAN control plane, and YANG that Packet Tracer does not model well.
   Cisco dCloud is free and has pre-built ENCOR topology labs. CML (Cisco
   Modeling Labs) Personal is worth the cost if you plan to push toward CCIE


3. 
   Dedicated automation practice. Do not just read about Python and REST
   APIs. Write a short Python script that calls a DNA Center sandbox API.
   Cisco DevNet has a free always-on DNA Center sandbox at
   
   
   to see the question style and reasoning depth before you commit to a study plan.
   
   Working through explanations for Infrastructure and Automation items shows you
   
   exactly how Cisco frames scenario logic, which is easier to absorb from worked
   
   examples than from video summaries.
   
   
   

   
   
   
   Who should NOT take 350-401?
   

   
   
   

   The exam is wrong for these candidates:

   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   

   You are	Take instead
   Brand new to networking with no Cisco experience	CCNA 200-301 first to build the foundation
   A pure cloud engineer who never configures Cisco gear	AWS, Azure, or GCP networking certifications
   Security-focused and not doing network operations	CCNP Security (SCOR 350-701) or CompTIA Security+
   Looking for vendor-neutral fundamentals validation	CompTIA Network+ is broader and cheaper
   A network engineer who only needs CCNA-level validation	Stay at CCNA until you have the production experience ENCOR expects

   
   
   

   The investment here is not just the $400 exam fee. It is 10 to 14 weeks of
   
   serious study time. That time is well spent for a working network engineer
   
   ready to move into senior roles. It is a poor investment for someone who
   
   wants a cert badge without the underlying experience the badge implies to
   
   hiring managers who actually verify it in interviews.

   
   
   

   
   
   
   What's next after 350-401?
   

   
   
   

   Passing ENCOR opens several paths:

   
   
   
   
   
   • 
     Complete CCNP Enterprise: Add one concentration exam. The most common
     pick is 300-410 ENARSI (Advanced Routing and Services), which deepens
     OSPF, BGP, EIGRP, and VPN troubleshooting. Other concentration options
     include 300-415 ENSDWI (SD-WAN) and 300-435 ENAUTO (Automation), depending
     on where your career is pointing.
   
   
   • 
     CCIE Enterprise lab path: ENCOR satisfies the written/qualifying
     requirement for both CCIE Enterprise Infrastructure and CCIE Enterprise
     Wireless. The lab exams are a separate and significantly harder undertaking,
     but ENCOR is the required gateway. Most engineers spend one to two years in
     production and focused lab work between passing ENCOR and attempting the
     CCIE lab.
   
   
   • 
     SD-WAN or Automation specialization: 300-415 ENSDWI and 300-435 ENAUTO
     are both viable concentration choices if your shop is deep in Viptela SD-WAN
     or Catalyst Center automation. Either makes a strong resume signal in
     enterprise sales engineering and network architect roles.
   
   
   • 
     DevNet Professional: If the Automation domain on ENCOR sparked genuine
     interest in network programmability, the Cisco DevNet Professional path
     (350-901 DEVCOR) builds directly on those skills.
   
   
   
   
   

   Note that Cisco certifications expire after three years. ENCOR's three-year
   
   clock starts on your pass date. You can renew by passing any 300-level or
   
   higher Cisco exam, or by passing ENCOR again, or by completing continuing
   
   education credits through the Cisco Learning Network.
