Which of the following description of the load sharing algorithm based on source and destination IP and port is correct?
A . This mode is generally used in scenarios where most of the network flow is inside the Layer 2 network. At this time, the network flow can be evenly hashed by MA
C . This mode has high reliability, but the network flow will only be shared by one network card, and the other network card serves as a backup.
D . When there are IP and port in the message, use the source and destination IP, port and MAC for load sharing; when the message has only an IP address, use the IP address and MAC for load sharing, when the message has only a MAC address, Use MAC address for load sharing.
E . This mode enables the network stream to be sent to each network port completely and evenly, but large messages may be out of order.

Answer: C
