About this exam

The Cisco ENCOR 350-401 exam, formally Implementing Cisco Enterprise Network Core Technologies, is the core written exam on the CCNP Enterprise path. Candidates typically work as enterprise network engineers, administrators, or architects who design, deploy, and operate Cisco campus, branch, and WAN infrastructure, and who need to prove breadth across routing, switching, wireless, security, virtualization, assurance, and automation rather than depth in a single track. Because ENCOR is a core exam, passing it is normally the prerequisite step before a concentration exam completes the CCNP Enterprise certification, and the same blueprint underpins the written requirement for the CCIE Enterprise Infrastructure track. The published domain weights are Architecture 15%, Virtualization 10%, Infrastructure 30%, Network Assurance 10%, Security 20%, and Automation 15%, so Infrastructure and Security together account for half the paper and deserve the largest share of your study calendar. Preparation should combine hands-on configuration on Cisco routers and switches, including controllers and virtualized infrastructure, with reading of configuration guides and design documentation, then timed practice that forces you to justify each answer. Treat the blueprint as a checklist, log weak domains after every practice set, and re-test those areas rather than re-reading material you already know. Confirm all administrative details on Cisco's official exam page before scheduling.

Common questions

About Cisco ENCOR 350-401 preparation

What is the ENCOR 350-401 exam for?

It is the core exam for CCNP Enterprise, titled Implementing Cisco Enterprise Network Core Technologies. It tests architecture, virtualization, infrastructure, assurance, security, and automation knowledge. Candidates usually sit it before a concentration exam, and it also serves as the written requirement for the CCIE Enterprise Infrastructure path. Verify current certification rules on Cisco's official pages before you schedule.

How much does each domain count?

The published weights are Architecture 15%, Virtualization 10%, Infrastructure 30%, Network Assurance 10%, Security 20%, and Automation 15%. Infrastructure and Security together are half the exam, so allocate study time accordingly. Do not neglect the smaller domains, since 10% of a scored exam is still enough to decide a pass or fail.

How should I order my study?

Start with Infrastructure and Security because they carry the most weight and overlap with routing and switching fundamentals. Add Architecture next, since it frames design decisions used elsewhere. Then cover Virtualization, Network Assurance, and Automation, which reward hands-on lab work more than reading. Finish with timed mixed practice sets that rotate all six domains.

What causes most failures?

The usual causes are narrow preparation on routing and switching only, skipping automation and assurance topics, and reading without configuring. Another common mistake is memorising commands without understanding why a design or feature is chosen. Track your accuracy per domain after each practice set and revisit the weakest areas instead of repeating comfortable material.

Is hands-on lab work necessary?

Yes. The exam expects practical understanding of configuration and verification, not just definitions. Build labs covering routing protocols, switching, wireless configuration through a controller, overlay technologies, and basic automation workflows. Practising verification commands and interpreting output is often what separates a confident answer from a guess during scenario questions.

What question format should I expect?

Cisco exams commonly include multiple-choice single and multiple-answer items, and some items may present a scenario requiring interpretation of configuration or output. The official source text retrieved for this page does not state the item count or format mix, so treat those details as unconfirmed and check the official exam page before your appointment.

How long is the exam and what does it cost?

The source material available here does not state a duration, question count, passing score, or fee, so no figures are given. Pricing varies by country and currency, and scheduling is handled through Cisco's certification tracking system. Confirm the current duration and price on Cisco's official exam page and your scheduling portal before booking.

Can I retake the exam if I fail?

Cisco's published retake policy is not included in the source text used for this page, so the specific waiting period and any fees are unconfirmed here. Retake rules do change, so check the official exam page or your certification tracking account for the current policy rather than relying on older information from forums or study groups.

How long is the certification valid?

The source text available here does not state a validity period or recertification requirements, so those details are left unconfirmed. Cisco publishes recertification options including continuing education credits and exam retakes. Check the CCNP Enterprise certification page for the current validity term and accepted recertification activities before your certification is due.

Does passing ENCOR alone give me CCNP Enterprise?

No. ENCOR is the core exam, and CCNP Enterprise also requires a concentration exam in a chosen focus area. The specific concentration options and their current titles are not detailed in the source text used here. Review the CCNP Enterprise certification page to select a concentration that matches your role.
