  • 第1题:

    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.
