350-401 Architecture — Key Topics
You must design and verify enterprise architectures using SD-WAN, SD-Access, OSPF area types, and QoS. The most important thing is to know how each technology segments, routes, and prioritizes traffic in a given scenario.
- Cisco SD-WAN segmentation using VPNs and VRF-aware routing for guest, employee, and IoT traffic
- SD-Access underlay requirements: IP reachability, MTU, and routing protocol consistency
- OSPF LSA types in totally stubby areas (Type 1, Type 2, Type 3 only)
- QoS low-latency queuing (LLQ) for strict priority of voice traffic on outbound interfaces
