Data is transferred between two servers using NFS, where one server is configured with token ring, and the other system is configured with ethernet. It is discovered that the performance is greatly reduced during this transfer. Which of the following steps should be taken to improve performance?()A、 Reduce MTU on token ring system to match ethernet system using ifconfig command (i.e. ifconfig tr0 mtu 1500)B、 Reduce MTU on token ring system to match ethernet system using no command (i.e. no -o mtu=1500)C、 Increase MTU on ethernet system to match token ring system using ifconfig command (i.e. ifconfig en0 mtu 4096)D、 Increase MTU on ethernet system to match token ring system using no command (i.e. no -o mtu=4096)
