Your computer has the IP address 172.16.64.201/22, and you try to access a website on the web server with the IP address 172.16.129.48/22. Unfortunately, you are unable to access the site. Below are the partial configurations on RouterA and RouterB: RouterA interface fastethernet3/1 ip address 172.16.64.1 255.255.252.0 interface serial0/0 ip address 172.16.22.190 255.255.255.252.0 ip route 172.16.128.0 255.255.252.0 172.16.24.185 RouterB interface fastethernet0/0 ip address 172.16.128.1 255.255.252.0 interface serial0/0 ip address 172.16.24.185 255.255.252.0 ip route 172.16.64.0 255.255.252.0 172.16.22.190 Why are you unable to access the website? A. The static route is incorrect on RouterA. B. The serial0/0 on RouterA is on a network different from serial0/0 on RouterB. C. The server is on a network different from fastethernet0/0 on RouterB. D. The static route on RouterB is incorrect. E. Your computer uses an invalid IP address B. The serial0/0 on RouterA is on a network different from serial0/0 on RouterB. 9.
