C. If two TCP connections are established between BGP peers, one TCP connection is torn down.

D. If there are "multiple" TCP connections between BGP peers, BGP keeps the TCP connection initiated by the peer with a greater BGP router ID.

B. Huawei switches support 64 isolation groups numbered 0 to 63.

C. If interface A is isolated from interface B, packets sent from interface A cannot reach interface B, but packets sent from interface can reach interface A.

D. FE interfaces, GE interfaces, XGE interfaces, and Eth-Trunks can be isolated from one another, but an interface cannot be isolated from itself or from the management interface unidirectionally. In addition, an Eth-Trunk cannot be isolated unidirectionally from its member interfaces.
