Choose all correct answers
Match concepts to definitions
Arrange steps in the correct order
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass 350-401 on their first attempt:
Answer before revealing
Read each 350-401 question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which 350-401 domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real 350-401 gives you roughly 1.3 minutes per question. Use the 60 or 120-question sessions to practise hitting that pace comfortably.
Most candidates who pass 350-401 on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 2,015+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.
Answer each question to reveal the full explanation and correct answer. This starter set is drawn from all 39 exam domains in blueprint proportion. Use the session selector to start a longer focused practice run.

A network engineer is deploying a Cisco SD-WAN solution for a global enterprise with multiple regional hubs. The engineer wants to ensure that traffic from branch offices to the internet is always forwarded directly from the branch, even if the branch has a primary MPLS link and a backup broadband link. The engineer configures the vSmart policy to direct internet-bound traffic to use the local exit at the branch. However, after deployment, the engineer notices that some internet traffic is still being sent to the regional hub before reaching the internet. What is the most likely cause of this behavior?

Answer all 20 questions to see your domain score breakdown
A structured study plan dramatically increases your chances of passing 350-401 on the first attempt. The most effective approach combines reading the official Cisco documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for 350-401 preparation:
Cover each 350-401 domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing 350-401 score.
On exam day, the 350-401 tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.

Every question is written against the official 350-401 exam blueprint published by Cisco. Our questions follow the same wording style, scenario complexity, and answer structure as the actual exam. They are original questions — not brain dumps — so you learn the underlying concepts and reasoning, not just memorised answers. Candidates who study with brain dumps often pass but have no transferable knowledge; Courseiva questions make you genuinely competent.
Most candidates who pass 350-401 on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The 350-401 covers 39 domains: Architecture (15%), Enterprise Network Design, SD-Access Architecture, SD-WAN Architecture, QoS Architecture, Virtualization (10%), Network Function Virtualization, Virtual Machines and Hypervisors, VRF and Path Isolation, Infrastructure (30%), OSPF, BGP, EIGRP, VLANs and Trunking, Spanning Tree Protocol, EtherChannel, Wireless Infrastructure, MPLS, WAN Technologies, NAT and DHCP, IP Multicast, QoS, Network Assurance (10%), SNMP and Syslog, NetFlow and Telemetry, SPAN and RSPAN, IP SLA, Security (20%), AAA, RADIUS, and TACACS+, ACLs and CoPP, 802.1X and TrustSec, VPN Technologies, Infrastructure Security, Automation (15%), Python for Network Automation, Ansible Automation, REST APIs and Data Models, Cisco DNA Center, Model-Driven Telemetry. Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Infrastructure and Security — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without Cisco's authorisation. Using them violates your NDA and Cisco's certification agreement, and can result in certification revocation. Courseiva questions are 100% original — written by certified engineers to test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
