Which of the following description is correct based on source and destination IP and port load sharing algorithm?
A . This mode is highly reliable, but the network traffic will only be shared by one network card, and the other network card serves as a backup
B . When the message contains IP and port, use the source destination IP port and MAC for load sharing; when the message has only IP address, use IP address and MAC for load sharing; when the message has only MAC address, use MAC address for load sharing
C . This mode is generally used in scenarios where most of the network traffic is inside the Layer 2 network. This network traffic can be evenly hashed by MAC
D . This mode uses network traffic to be sent to each port completely and evenly, but a large number of messages may be out of order
Answer: B.
