Every question is written by certified engineers against the 2026 350-401 exam objectives. These are original practice questions — not dumps — so you build real understanding rather than memorising answers.
Both the mock exam and practice test use the same question bank. The difference is in how you use them — and when to use each during your 350-401 study plan.
Practice test — for learning
Use the 350-401 practice test when you are studying a domain. Answer questions, read every explanation immediately, and build understanding. Do 10–30 questions per domain per session. This is your primary study tool for the first 4 weeks.
Go to practice test →Mock exam — for simulation
Use the 350-401 mock exam in the final 1–2 weeks before your test date. Complete a 60 or 120-question session without stopping, manage your time, then review all results at the end. This builds exam-day stamina and surfaces final weak spots.

A network engineer is deploying Cisco SD-Access in a large enterprise campus. The design requires that all user traffic be segmented by Virtual Network (VN) and that the fabric edge nodes perform SGT-based enforcement. The engineer notices that traffic between two endpoints in the same IP subnet but different VNs is being forwarded directly at the fabric edge without any SGT inspection. What is the most likely cause?

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?

A network engineer is configuring QoS on a Cisco Catalyst 9300 switch to prioritize voice traffic. The switch has multiple access ports connected to IP phones and PCs. The engineer applies a policy-map that matches DSCP EF and sets the CoS to 5. However, after testing, the voice packets are not being marked correctly. What is the most likely cause?

A network engineer is troubleshooting a Cisco IOS-XE router that hosts multiple virtual routing and forwarding (VRF) instances. Users in VRF-A report they cannot reach a server in VRF-B. The engineer verifies that both VRFs have the correct routes and that the router has a route leaking configuration using route-target import/export. However, connectivity still fails. What is the most likely cause?

A company is migrating its legacy firewall services to a virtualized environment using Cisco NFV. The network engineer deploys a virtual firewall (vFW) on an NFVIS-enabled UCS platform. After the deployment, traffic through the vFW is intermittent and performance monitoring shows high CPU usage on the host. Which action should the engineer take to improve performance?

A network engineer is deploying a new virtualized application on a VMware vSphere cluster. The application requires dedicated CPU cores to meet licensing requirements, and the engineer must ensure that no other virtual machine can use those cores. The cluster uses VMware ESXi 7.0. Which configuration should the engineer apply to the virtual machine?
Select an answer to reveal the explanation
A network engineer is configuring MPLS L3VPN on a Cisco IOS-XE PE router. The engineer creates a VRF named CUSTOMER_A with route-target import and export 100:1. After configuring the VRF on the interface connected to the CE router, the CE router can ping the PE's VRF interface IP, but cannot reach any remote VPNv4 routes. The BGP session between PE and route reflector is up. What is the most likely cause?

A company is implementing QoS in a campus network. Voice traffic must be prioritized over data traffic, and all traffic should be marked at Layer 2 and Layer 3. Which combination of marking values should be used on access ports to achieve this?
Select an answer to reveal the explanation
An engineer needs to configure a switchport to carry traffic for multiple VLANs to a router using a single physical link. Which configuration should be applied on the switchport?
Select an answer to reveal the explanation
A network engineer is troubleshooting OSPF adjacency issues between two routers connected via a Gigabit Ethernet link. The engineer notices that the routers are stuck in the EXSTART state. Both routers have the same MTU of 1500 bytes. What is the most likely cause of this issue?
Select an answer to reveal the explanation
An enterprise network has two routers, R1 and R2, both running BGP. R1 is an eBGP speaker with ISP1, and R2 is an eBGP speaker with ISP2. Both routers are in the same AS 65000. The engineer wants to ensure that traffic from the enterprise to the Internet prefers the path through ISP1 when both links are up. R1 learns a default route from ISP1, and R2 learns a default route from ISP2. Which BGP attribute should the engineer modify on R1 to influence outbound traffic selection?
Select an answer to reveal the explanation
A network engineer is troubleshooting an EIGRP issue in a large enterprise network. Two routers, R1 and R2, are connected via a T1 link. R1 is learning a route to 10.0.0.0/8 from R2 with a metric of 28160, but the same route is also learned from another neighbor with a metric of 26880. The engineer notices that the route from R2 is not being installed in the routing table. What is the most likely cause?

Answer all 15 questions to see your domain score breakdown
Sitting the 350-401 under real exam conditions is a skill in itself. Candidates who underperform often do so not because of knowledge gaps, but because of poor time management or test anxiety. Use your final mock exam sessions to address both.
The 350-401 exam lasts 120 minutes. Do not spend more than 90 seconds on any single question on the first pass. Flag difficult ones and return to them after completing the rest.
On every question, immediately eliminate obviously wrong choices. Even if you are unsure between two options, narrowing to two doubles your odds. Most 350-401 distractors contain a subtle error — re-read the scenario constraint before committing to the answer that sounds most familiar.
Cisco writes many 350-401 questions as realistic scenarios. Read the final sentence first — it tells you what is being asked. Then re-read the scenario with the question in mind to avoid wasting time on irrelevant details.
The real 350-401 is a mental marathon lasting 120 minutes. In the week before your exam, complete at least two full timed mock sessions on separate days to build concentration stamina. If you cannot stay focused for 120 minutes in practice, you will struggle on exam day.
