CompTIA Network+ (N10-007) — Question 593

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?

Answer options

• 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.

Correct answer: A

Explanation

The correct answer is A because placing the modem in bridge mode allows the router to handle the public IP address directly, which is necessary for the web server to be accessible from the Internet. Options B, C, and D misconfigure the roles of the devices, leading to potential connectivity issues or preventing the web server from being accessible externally.
