質問 4：
Which of the following descriptions of VNI in a VXLAN network is correct?
A. A tenant can have one or more VNIs with a VNI length of 16 bits, supporting millions of tenants
B. L3 VNI is associated with a VPN instance to forward VXLAN packets across subnets, and VPIN instances associated with different L3 VNIs only need to be RT Values can be matched to achieve interoperability

質問 6：
What are the correct terms of the following descriptions of underlays and overlay networks?
A. When implementing the overlay technology in the underlay network, the original underlay network needs to be modified to a certain extent
B. Overlay Routes for the network are generated by routes that are ingested into the underlay network
C. Underlay is logically isolated from overlay, and as long as the routes between tunnel endpoints are reachable, the failure of the underlay network will not directly affect the overlay network
D. From the perspective of an overlay network, the underlay network is transparent to devices connected outside of the VXLAN tunnel endpoints
