Which two statements or sets of statements are true about the application of the qos pre-classify command？（）A、 If the classification policy is based upon the ToS byte， the qos pre-classify command is required because the ToS byte only appears in the inner IP header.B、 The ToS byte is copied to the outer header by default. Therefore， the qos pre-classify command is not necessary.C、 With GRE encapsulation， the qos pre-classify command is applied on the tunnel interface. This practice allows for different OoS configurations on each tunnel.D、 With GRE encapsulation， the qos pre-classify command is applied on the physical interface. This practice allows for different OoS configurations on each interface.E、 With IPsec encapsulation， the qos pre-classify command is applied on the physical interface. This practice allows for different OoS configurations on each interface.
