CompTIA Network+ (N10-007) — Question 25

A home user is unable to get to the Internet from a workstation that is connected to a wireless network. When reviewing the results of the ipconfig command, the user wants to verity the default gateway is correct. Which of the following devices should be the gateway?

Answer options

• A. Cable modem
• B. SOHO router
• C. DNS server
• D. Layer 2 switch

Correct answer: A

Explanation

The correct answer is A, as the cable modem connects the home network to the Internet and functions as the gateway. Option B, the SOHO router, typically routes traffic within the network but does not serve as the direct gateway to the Internet. Options C and D are not valid as a DNS server resolves domain names and a Layer 2 switch operates at the data link layer without providing Internet access.
