iMaster NCE-Fabric is Huawei's DC controller. Tenants can use it to create VPCs and deploy logical networks as required. After logical NEs are…

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 3 communication 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, A is the false statement because logical switches are for Layer 2, not Layer 3, communication.
