Question 8

An MSR router is connected to the Internet through the S1/0 interface, and the GE0/0 interface is connected to the LAN host. The network segment of the LAN host is 10.0.0.0/8, and there is an FTP server with an IP address of 202.102.2.1 on the Internet.
By configuring the IP address and routing on the router, the hosts in the current LAN can access the Internet normally (including the public network FTP server). Now the following configuration is added to the router:
firewall enable
acl number 3000
rule 0 deny tcp source 10.1.1.1 0 source-port eq ftp destination 202.102.2.1 0
Then apply this ACL to the inbound and outbound directions of the GE0/0 interface, then which of the following intentions can this ACL achieve?

A.Only prohibit the FTP control connection from the host whose source address is 10.1.1.1 to the destination host's 202.102.2.1 whose port is TCP 21

B.Only prohibit the FTP data connection from the host whose source address is 10.1.1.1 to the destination host 202.102.2.1 whose port is TCP 20

C.There is no restriction on the FTP connection initiated from 10.1.1.1 to 202.102.2.1

D.The host whose source address is 10.1.1.1 is prohibited from initiating FTP connection to the destination host 202.102.2.1

Question 9
