A. TRUE

B. FALSE

A. A leaf node can function as both a Layer 2 VXLAN gateway and a Layer 3 VXLAN gateway, supporting flexible deployment.

B. A distributed VXLAN gateway (leaf node) only needs to learn the ARP entries of servers connected to it, whereas a centralized Layer 3 VXLAN gateway needs to learn the ARP entries of all servers on a network. Therefore, the number of ARP entries supported is no longer a bottleneck on distributed VXLAN gateways, and the network scalability is improved.

C. Forwarding paths are not optimal. Inter-subnet Layer 3 traffic between devices connected to the same gateway in a data center must be transmitted to a unified Layer 3 gateway for forwarding.

D. The number of ARP entries supported is a bottleneck. A single Layer 3 gateway is used. For tenants whose traffic is forwarded by the Layer 3 gateway, ARP entries must be generated for the tenants on the Layer 3 gateway, but only a limited number of ARP entries are allowed by the Layer 3 gateway, which impedes data center network expansion.

A. Network overlay applies to private cloud users who have high requirements for the forwarding performance, O & M, and security.

B. The controller delivers flow tables to NVEs synchronously.

C. NVEs can be deployed on physical switches.

D. Virtual and physical servers can access the network.

A. Select the model of server leaf nodes based on the server access bandwidth (10GE/25GE access) and the ratio of server leaf nodes ' uplink bandwidth to spine nodes ' downlink bandwidth.

B. The M-LAG, stacking, and standalone modes are often used for server access. Stacking is recommended because it can ensure service continuity during the upgrade of access switches.

C. Select the model of server leaf nodes depending on whether microsegmentation or IPv6 deployment or evolution towards them is required.

D. Determine the number of server leaf nodes based on the number of servers.

A. IPsec VPN

B. GRE

C. SSL VPN

D. VXLAN

A. The devices (such as servers, VAS devices, and external routers) connected to NVEs are unaware of the underlay network.

B. An overlay network is a logical network defined on a physical bearer network (underlay network).

C. Generally, the overlay network is implemented through VXLAN.

D. The overlay and underlay networks must use the same routing protocol.

A. Not isolated

B. Bidirectionally isolated

C. Unidirectionally isolated
