A GRE tunnel is configured between a local and a remote site. Where should the service policy be applied to classify packets based on the pretunnel header? （）A、in global configuration mode， apply the service policy and use the qos pre-classifyB、in global configuration mode， apply the service policy but do not use the qos pre-classify commandC、apply the service policy on the physical interface but do not use the qos pre-classifyD、apply the service policy on the tunnel interface but do not use the qos pre-classify command E、apply the service policy on the tunnel interface and use the qos pre-classify command
考题
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.
