A client with IP address 209.165.201.25 must access a web server on port 80 at 209.165.200.225. To allow this traffic, an engineer must add a statement to an access control list that is applied in the inbound direction on the port connecting to the web servers. Which statement allows this traffic?: [+ A) c" @! U5 [7 c# F3 u/ f
C1 ?- W+ K+ r' V5 bA. permit tcp host 209.165.200.225 lt 80 host 209.165.201.25: s" D$ S+ x: G5 A
B. permit tcp host 209.165.201.25 host 209.165.200.225 eq 80+ D- q4 r( q8 F" r- D
C. permit tcp host 209.165.200.225 eq 80 host 209.165.201.25
) Y% X$ Z9 G y fD. permit tcp host 209.165.200.225 host 209.165.201.25 eq 80
$ G5 R1 Z0 X. N, x9 A% }' @1 o3 n$ i
這題B和C各持一方,但我認為是C , 因為題目是 inbound 方向 O, P# p& W: R' P7 S1 T
