CompTIA Network+ (N10-007) — Question 591

A network technician is setting up a newly installed Internet connection at a SOHO that will support up to ten devices on the network. The company is required to provide its own router to connect to the Internet. The ISP has assigned an IP address of 173.28.199.67/32 to the office. Which of the following does the network technician need to perform to ensure all devices on the network can access the Internet?

Answer options

• A. Configure the local machines to get an IP address from the ISP automatically.
• B. Configure each host with a static IP address within the 173.28.199.0 block.
• C. Configure the router's static IP and create a NAT for the local network address of 10.10.10.0/24.
• D. Configure each host to use its link local addresses for network discovery.

Correct answer: C

Explanation

The correct answer is C because the router needs to have a static IP configured and a NAT (Network Address Translation) set up to allow multiple devices on the local network to access the Internet using a single public IP address. Option A is incorrect as the ISP's IP is static and not assigned dynamically. Option B is wrong because the assigned IP address is a /32, meaning only one device can directly use it without NAT. Option D is not suitable since link local addresses are not routable and cannot be used to access the Internet.
