Which of the following descriptions of BD in a VXLAN network is correct?

A.

BD messages are encapsulated in VXLAN packets to identify a large Layer 2 broadcast domain

B.

In a VXLAN network, the BD and the VLAN tag of the connected service packet form a 1:N mapping

C.

In a VXLAN network, BD is a local concept, and as long as the L2 VNI is the same on different leaves, it can be considered to be in the same large Layer 2 broadcast domain

D.

Which of the following descriptions of multivariate computation is wrong?

A.

Multivariate computing can provide basic general-purpose computing, artificial intelligence computing, and high-performance computing, all of which need to be carried over lossless networks

B.

The basic computing power corresponding to the basic general technology mainly refers to the computing power provided by the server based on the CPU chip

C.

The intelligent AI computing power corresponding to AI computing mainly refers to the computing power provided by accelerated computing platforms based on chips such as CPUs, NPUs, and FPGA ASICs to provide AI training and inference

D.

The supercomputing power corresponding to high-performance computing mainly refers to the computing power provided by high-performance computing clusters such as supercomputers
