- A
Cisco DNA Center is used to design and provision the SD-Access fabric, including defining virtual networks and host pools.
Correct because DNA Center provides the GUI and API to create fabric domains, IP pools, and virtual networks (VRFs).
- B
Cisco DNA Center automatically configures OSPF as the control plane protocol for SD-Access.
Why wrong: Incorrect because SD-Access uses LISP as the control plane protocol; OSPF is used for underlay routing but not as the fabric control plane.
- C
Cisco DNA Center can enforce group-based policies using Scalable Group Tags (SGTs) in the SD-Access fabric.
Correct because DNA Center integrates with Cisco ISE to define and apply SGT-based policies across the fabric.
- D
Cisco DNA Center requires a separate WAN controller to manage SD-Access border nodes.
Why wrong: Incorrect because DNA Center directly manages border nodes as part of the fabric; no separate WAN controller is needed.
- E
Cisco DNA Center configures SD-Access edge nodes as the core routers of the network.
Why wrong: Incorrect because edge nodes are access-layer switches that connect endpoints, not core routers; core routers are part of the underlay.
Quick Answer
The answer is that Cisco DNA Center can enforce group-based policies using Scalable Group Tags (SGTs) in the SD-Access fabric. This is correct because DNA Center serves as the centralized management and automation platform for the entire SD-Access solution, translating business intent into network policies. It handles fabric design, provisioning, and policy enforcement by mapping users and devices to SGTs, which are then carried across the fabric using LISP as the control plane and VXLAN for data encapsulation. On the ENCOR 350-401 exam, this topic tests your understanding of how DNA Center integrates with SD-Access components, often using distractors that confuse the control plane (LISP, not OSPF) or misassign device roles (edge switches, not core). A common trap is assuming DNA Center handles real-time forwarding or replaces the border node’s WAN role. Remember: DNA Center designs and enforces policy, but LISP controls the map, and VXLAN carries the traffic.
350-401 Cisco DNA Center Practice Question
This 350-401 practice question tests your understanding of cisco dna center. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which two statements about Cisco DNA Center integration with Cisco SD-Access are true? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Cisco DNA Center is used to design and provision the SD-Access fabric, including defining virtual networks and host pools.
DNA Center is the management and automation platform for SD-Access. The correct answers describe its role in fabric design and policy enforcement. The incorrect options misrepresent the control plane (LISP, not OSPF), the border role (fabric exit, not WAN), and the device role (edge, not core).
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

Common exam traps
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
- OSPF neighbours must agree on key parameters.
- Router ID selection can affect neighbour relationships and LSDB output.
- OSPF cost influences the preferred path.
- A route can appear in OSPF information but not become the installed route.
TExam Day Tips
- Check area mismatch first when OSPF adjacency fails.
- Review passive interfaces when a network is advertised but no neighbour forms.
- Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Real-world example
How this comes up in practice
A network engineer at a university connects two campus buildings via a fibre link. Both routers run OSPF, but no adjacency forms — even though both routers can ping each other. The engineer finds one router is in area 0 and the other in area 1. OSPF adjacency requires matching area numbers, hello/dead timers, and network type. IP reachability alone is not enough.
What to study next
Got this wrong? Here's your next step.
Review OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related 350-401 OSPF questions on adjacency and route selection.
