Q210. CORRECT TEXT - (Topic 9) 

A corporation wants to add security to its network. The requirements are: 

. Host C should be able to use a web browser (HTTP) to access the Finance Web Server. 

. Other types of access from host C to the Finance Web Server should be blocked. 

. All access from hosts in the Core or local LAN to the Finance Web Server should be blocked. 

. All hosts in the Core and on local LAN should be able to access the Public Web Server. 

You have been tasked to create and apply a numbered access list to a single outbound interface. This access list can contain no more than three statements that meet these requirements. 

Access to the router CLI can be gained by clicking on the appropriate host. 

All passwords have been temporarily set to “cisco”. 

The Core connection uses an IP address of 198.18.209.65. 

The computers in the Hosts LAN have been assigned addresses of 192.168.78.1 – 192.168.78.254. 

host A 192.168.78.1 

host B 192.168.78.2 

host C 192.168.78.3 

host D 192.168.78.4 

The Finance Web Server has been assigned an address of 172.22.146.17. 

The Public Web Server in the Server LAN has been assigned an address of 172.22.146.18.
