Cisco 350-401 — Frequently Asked Questions (FAQs)
SECTION A: Cisco 350-401 Certification Overview
Q1. What is the Cisco 350-401 exam?
The Cisco 350-401 exam, Implementing Cisco Enterprise Network Core Technologies (ENCOR), is the core enterprise networking exam for the CCNP Enterprise and CCIE Enterprise Infrastructure certifications. Passing it on its own also earns the Cisco Certified Specialist – Enterprise Core credential. The current version is ENCOR v1.2, a 120-minute exam whose largest domain is Infrastructure (30%), covering switching, routing and IP services.
Q2. Who should take the Cisco 350-401 exam?
The Cisco 350-401 exam is aimed at network engineers who implement core enterprise network technologies, which Cisco lists as dual stack (IPv4 and IPv6) architecture, virtualization, infrastructure, network assurance, security, and automation. Engineers working toward CCNP Enterprise or CCIE Enterprise Infrastructure take it as the core exam of either track. Cisco states no prerequisites for 350-401, but its Infrastructure domain expects candidates to configure simple OSPFv2/v3 environments and eBGP between directly connected neighbors, so hands-on configuration experience helps.
Q3. What skills does the Cisco 350-401 exam measure?
The Cisco 350-401 exam measures the ability to implement core enterprise network technologies across six weighted domains. Architecture (15%) covers enterprise design, Cisco SD-Access and Cisco Catalyst SD-WAN; Virtualization (10%) covers hypervisors, VRF, GRE and IPsec tunnels, LISP and VXLAN; Infrastructure (30%) covers Layer 2 switching, OSPF, EIGRP and eBGP routing, and IP services such as NAT/PAT, HSRP and multicast. Network Assurance (10%) covers diagnostic tools, Flexible NetFlow, SPAN, IP SLA, NETCONF and RESTCONF; Security (20%) covers AAA device access, ACLs, CoPP and security design; Automation and Artificial Intelligence (15%) covers Python, JSON, YANG, EEM, and the Cisco Catalyst Center and SD-WAN Manager APIs.

Q4. How many questions are on the Cisco 350-401 exam?
Cisco does not publish a question count for the 350-401 ENCOR exam; the official exam page gives the 120-minute time limit instead. The exam mixes performance-based, multiple-choice and drag-and-drop questions, and Cisco provides an exam tutorial that shows each format before test day. With no count to plan around, pacing is better built from the 120 minutes and the domain weights, which put Infrastructure (30%) well ahead of Virtualization (10%) and Network Assurance (10%).
Q5. How long is the Cisco 350-401 exam?
The Cisco 350-401 exam lasts 120 minutes. The exam is timed and proctored, whether it is taken at a test center or online, and those 120 minutes cover every format it uses: performance-based, multiple-choice and drag-and-drop questions. Cisco reports the result as pass or fail, typically online within 48 hours.
Q6. What types of questions appear on the Cisco 350-401 exam?
The Cisco 350-401 exam uses performance-based questions, multiple-choice questions and drag-and-drop questions, according to Cisco's ENCOR exam-topics page. Cisco provides an exam tutorial that demonstrates each format before test day. Many v1.2 exam topics are written as tasks rather than definitions: Infrastructure asks candidates to configure and verify OSPF, eBGP and HSRP, and Automation and Artificial Intelligence asks them to interpret Python scripts and construct valid JSON.
Q7. Can I take the Cisco 350-401 exam online or at a test center?
Both options are available: the 350-401 exam is delivered through Pearson VUE, either at a test center or by online proctoring. Cisco states that all of its Associate, Professional and Expert written exams are offered both ways, and either way the exam is proctored, timed and delivered in a secure environment. For the online option, Cisco advises installing the OnVUE software in advance to confirm the computer works with it, and choosing the "home or office" option when scheduling.
Q8. What score do I need to pass the Cisco 350-401 exam?
Cisco does not publish a passing score for the 350-401 exam, and results are reported as pass or fail, typically online within 48 hours. Without a published cut score, the sensible goal is dependable performance in every domain rather than a target percentage, with extra attention to Infrastructure (30%) and Security (20%), the two heaviest domains of the v1.2 exam topics.
SECTION C: Cisco 350-401 Difficulty & Readiness
Q9. How difficult is the Cisco 350-401 exam?
The Cisco 350-401 exam is demanding at the professional level: its v1.2 topics span six domains, and many ask candidates to configure, verify or troubleshoot rather than only explain. The blueprint runs from EtherChannel troubleshooting and OSPF, EIGRP and eBGP in Infrastructure (30%) to the working principles of Cisco SD-Access and Cisco Catalyst SD-WAN in Architecture (15%) and REST API response codes in Automation and Artificial Intelligence (15%). Its performance-based questions reward applied skill, so memorizing terms leaves gaps; a candidate who has configured these technologies on real or virtual equipment is better placed than one who has only read about them.
Q10. What makes the Cisco 350-401 exam challenging?
Much of the challenge in the Cisco 350-401 exam comes from technologies the v1.2 exam topics list side by side, which have to be told apart precisely. Infrastructure pairs HSRP with VRRP, RSTP with MST and root guard with BPDU guard, and asks for a comparison of EIGRP and OSPF; Network Assurance pairs NETCONF with RESTCONF, Security pairs TrustSec with MACsec, and Automation and Artificial Intelligence compares agent-based and agentless orchestration tools. Breadth adds to that, since the same 120 minutes also reach multicast topics such as PIM, SSM and MSDP.
SECTION D: Cisco 350-401 Preparation Strategy
Q11. How should I start preparing for the Cisco 350-401 exam?
Start preparing for the Cisco 350-401 exam by downloading the official ENCOR v1.2 exam-topics document and rating your current skill against each topic in its six domains. Plan study time by weight, beginning with Infrastructure (30%), and set up a lab on real or virtual equipment early, because hands-on practice is the most direct preparation for configure-and-verify topics such as EtherChannel, OSPFv2/v3, eBGP peering, VRF, GRE tunnels, AAA and CoPP. Cisco also publishes an ENCOR learning path on Cisco U.
Q12. Which skills should I focus on to pass the Cisco 350-401 exam?
Focus first on Infrastructure, the heaviest 350-401 domain at 30%, and then on Security at 20%, before the smaller domains. In Infrastructure, the core skills are troubleshooting 802.1Q trunks and EtherChannels, configuring RSTP and MST with root guard and BPDU guard, comparing EIGRP and OSPF, configuring eBGP, and IP services such as NAT/PAT, NTP and HSRP. In Security, they are device access control with local users and AAA, plus ACLs and CoPP. Architecture and Automation and Artificial Intelligence, at 15% each, add Cisco Catalyst SD-WAN working principles, Python and JSON, ahead of Virtualization and Network Assurance at 10% each.
Q13. How long should I prepare for the Cisco 350-401 exam?
Cisco sets no required study period for the 350-401 exam, so preparation time is best sized by measuring current skills against each v1.2 domain and its weight. Engineers who already configure OSPF, EtherChannel and AAA day to day start with much of the Infrastructure domain in hand, while candidates new to Cisco Catalyst SD-WAN, Cisco SD-Access or Python scripting should budget extra time for those topics. Cisco's ENCOR learning path on Cisco U. can provide a structure for that plan.
Q14. How should I use practice exams to prepare for the Cisco 350-401 exam?
Use practice exams for the Cisco 350-401 exam as a diagnostic: take one timed set early, then let each wrong answer point to a specific v1.2 exam topic to restudy. Log misses by domain and by topic, for example eBGP neighbor verification in Infrastructure or REST API response codes in Automation and Artificial Intelligence, and fix each one in a lab before retesting. Read the explanation for every item, including lucky guesses. Treat a domain as finished only when each of its v1.2 objectives has been practised, down to constructing an EEM applet or interpreting a QoS configuration.
SECTION E: Cisco 350-401 Practice Exams & Preparation Tools
Q15. Do practice tests help when preparing for the Cisco 350-401 exam?
Yes, practice tests help with 350-401 ENCOR preparation, chiefly by showing which of the six domains are weak well before exam day. A score broken down by domain exposes gaps, such as the Network Assurance tools SPAN, IP SLA and Flexible NetFlow, that an overall percentage can conceal. Cisco publishes an official ENCOR practice exam on Cisco U. as one option. Practice questions rehearse the multiple-choice and drag-and-drop formats well, but the performance-based questions also call for lab time configuring the technologies themselves.
Q16. Should I take practice exams or read study guides to prepare for the Cisco 350-401 exam?
Both, in sequence: study guides build the knowledge behind the ENCOR v1.2 exam topics, and timed practice exams test whether that knowledge holds up under the 350-401 exam's 120-minute limit. Reading alone tends to leave gaps on the tasks the topics are written around, such as interpreting a QoS configuration or a RESTCONF response payload, which practice questions force a candidate to work through. Neither replaces lab work for configure-and-verify topics such as VRF or Flexible NetFlow, since the exam includes performance-based questions.
Q17. What should I look for in study resources for the Cisco 350-401 exam?
Good study resources for the Cisco 350-401 exam are mapped to the ENCOR v1.2 exam topics and use Cisco's current product names. Material that still teaches Cisco DNA Center or vManage as current names, or spends chapters on wireless design, was likely written for v1.1; v1.2 uses Cisco Catalyst Center and SD-WAN Manager and dropped the wireless topics. Look for labs that cover the configure-and-verify topics in Infrastructure and Network Assurance, and for original practice questions whose explanations teach why each option is right or wrong; a book or the Cisco U. course combined with labs and practice covers knowledge, hands-on skill and pacing.
SECTION F: Cisco 350-401 Career & Certification Value
Q18. Is the credential earned by passing the Cisco 350-401 exam worth it?
Yes, for engineers who implement enterprise networks and intend to pursue CCNP Enterprise or CCIE Enterprise Infrastructure, because 350-401 ENCOR is the core exam both of those certifications require. Passing it also earns Cisco Certified Specialist – Enterprise Core on its own. The credential fits the hands-on enterprise engineering work Cisco names as the exam's focus, which runs from dual stack architecture through network assurance and automation. Against that, weigh the USD 400 exam price and the 3-year validity, after which recertification is required.
Q19. Does the credential earned by passing the Cisco 350-401 exam expire?
Yes, the Cisco Certified Specialist – Enterprise Core credential earned by passing 350-401 ENCOR is active for 3 years. Holders recertify by retaking the exam, advancing to a higher-level certification, or earning Continuing Education (CE) credits, and Cisco sets the CCNP renewal requirement at 80 CE credits. Anyone recertifying by exam sits the version current at that time, so a holder who passed v1.1 should prepare for the v1.2 topics, including the renamed Automation and Artificial Intelligence domain.
Q20. How does the Cisco 350-401 exam relate to other Cisco exams and credentials?
The Cisco 350-401 exam is the shared core exam of two Cisco certifications, CCNP Enterprise and CCIE Enterprise Infrastructure, and passing it alone earns Cisco Certified Specialist – Enterprise Core. ENCOR supplies the shared core, such as the Infrastructure and Security knowledge both tracks build on, so one pass counts toward both at once. The remaining requirements of each certification are set out on Cisco's own CCNP Enterprise and CCIE Enterprise Infrastructure pages, which are the place to confirm what follows ENCOR on either path.
Ready to move from reading to practice? The fastest way to turn this overview into real exam readiness is deliberate, timed practice: work through structured Cisco 350-401 practice tests that mirror the real exam’s format and domain weighting, then use your results to see exactly where you stand. Track your score by domain rather than by overall percentage, revisit every question you miss — including the ones you only guessed correctly — and keep practising a topic until you can answer it confidently without hesitation. Repeating that cycle in the weeks before test day is what builds the speed, accuracy, and confidence the Cisco 350-401 exam rewards.
