In each VPC, you can create one logical router, multiple logical switches, and multiple logical ports.

• A.TRUE
• B.FALSE

(Reliability design is important for the physical network design of a data center. Which of the following are true about reliability design principles?)

• A.Uplink reliability of leaf nodes: ECMP is implemented between leaf and spine nodes through multiple links.
• B.Server link reliability: One server is dual-homed to two server leaf nodes, and NICs on a server work in load balancing or active/standby mode. If one server link fails, services are switched to the redundant or standby link.
• C.When modular switches are deployed on the network, the inter-card connection is recommended for uplinks and downlinks, stack link, and peer-link of modular switches to implement card-level reliability.
• D.Peer-link fault: When the peer-link in an M-LAG fails, the DAD mechanism prevents dual master devices on the network and improves reliability.

One logical switch can be associated with only one subnet, and one subnet can be associated with only one logical switch.

• A.TRUE
• B.FALSE

Which of the following statements is false about in-band and out-of-band deployment of iMaster NCE-Fabric?

• A.In in-band deployment mode, the management network and service network share service network ports. The southbound IP address of iMaster NCE-Fabric communicates with the management IP addresses of devices through the service network.
• B.In out-of-band deployment mode, iMaster NCE-Fabric connects to the management interfaces of devices through the out-of-band management switch.
• C.In in-band deployment mode, service network ports have redundant connections, eliminating single points of failure and providing high reliability.
• D.In in-band deployment mode, the management network and service network are isolated and do not affect each other.

(Which of the following statements is false about the underlay and overlay networks?)

• A.An overlay network is a logical network defined on a physical bearer network (underlay network).
• B.Generally, the overlay network is implemented through VXLAN.
• C.The devices (such as servers, VAS devices, and external routers) connected to NVEs are unaware of the underlay network.
• D.The overlay and underlay networks must use the same routing protocol.
