Best Configuration for Web Server Setup

A technician is replacing a failed SOHO router for a customer who has an existing switch, cable modem, and static IP address.

The user has a web server that faces the Internet so users can visit and leave comments.

Which of the following BEST describes the correct configuration for this customer's requirements?

A.

The modem is placed in bridge mode, the router is placed behind the modem, and the web server is placed behind the router.

B.

The router is placed in bridge mode, the modem is placed behind the router, and the web server is placed behind the modem.

C.

The web server is placed in bridge mode, the router is placed behind the web server, and the modem is placed behind the router.

D.

The switch is placed in bridge mode, the modem is placed behind the router, and the router is placed behind the modem.

A.

The correct configuration for this customer's requirements would be to place the modem in bridge mode, place the router behind the modem, and place the web server behind the router. This is described in option A.

Explanation:

• The modem is placed in bridge mode: This means that the modem will not perform any routing functions and will simply pass on the Internet connection to the router. The reason for this is that the customer already has a static IP address, so they do not need the modem to perform any DHCP functions.
• The router is placed behind the modem: This allows the router to perform the necessary routing functions and manage the traffic from the web server and other devices connected to the network. The router will also provide NAT (Network Address Translation) to allow multiple devices on the customer's network to share the same public IP address.
• The web server is placed behind the router: This allows the web server to be protected by the router's firewall and other security features. By placing the web server behind the router, the customer can ensure that only authorized traffic is allowed to reach the server.

Option B is incorrect because placing the router in bridge mode would not allow it to perform the necessary routing functions, and placing the modem behind the router would create a double NAT scenario, which can cause issues with certain applications.

Option C is incorrect because placing the web server in bridge mode would essentially disable its network functionality, and placing the router behind the web server would not allow the router to perform its routing functions properly.

Option D is incorrect because placing the switch in bridge mode would disable its network functionality, and placing the modem behind the router would create a double NAT scenario, which can cause issues with certain applications.
