iMaster NCE-Fabric is Huawei's DC controller.

iMaster NCE-Fabric automates network configuration delivery in Huawei’s CloudFabric. Let’s evaluate each statement:

A. Logical switches are mainly used for Layer 3 communication between hosts on a VXLAN network. These switches correspond to Layer 3 gateway configurations such as VBDIF interface and VPN instance configurations on physical devices:This is false. Logical switches in iMaster NCE-Fabric primarily handle Layer 2 communication (e.g., bridging within a VNI), corresponding to Bridge Domains (BDs) and Layer 2 VNIs. Layer 3communication is managed by gateways, not logical switches.FALSE.

B. An end port represents an online host. It corresponds to the traffic encapsulation type (whether a VLAN tag is carried) configured on a Layer 2 sub-interface of a physical device:This is true. End ports map to host connections, with encapsulation (VLAN-tagged or untagged) configured on sub-interfaces.TRUE.

C. A logical port is equivalent to an independent physical port that is used by a host to connect to a VXLAN network. It corresponds to the Layer 2 sub-interface configuration on a physical device:This is true. Logical ports represent host connections, mapped to Layer 2 sub-interfaces for VXLAN access.TRUE.

D. Logical switches are mainly used for Layer 2 communication between hosts on a VXLAN network. These switches correspond to BD and Layer 2 VNI configurations on physical devices:This is true. Logical switches facilitate Layer 2 connectivity, aligning with BD and VNI settings.TRUE.

Thus,Ais the false statement because logical switches are for Layer 2, not Layer 3, communication.References:Huawei CloudFabric Data Center Network Solution – iMaster NCE-Fabric Configuration; HCIP-Data Center Network Training – Logical Network Mapping.
