CompTIA A+ Core 1 (220-1001) — Question 398

A technician is setting up a new wireless network at a branch office that previously had only wired connectivity with statically assigned IP addresses. After setting up the network, the technician configures a server to provide IP addresses to wireless clients. During testing, the technician is unable to access the Internet or named network resources. The technician receives a valid IP address from the DHCP server and can ping the default gateway.
Which of the following should be technician check NEXT to resolve this issue?

Answer options

• A. Ensure the options are configured to provide a DNS server.
• B. Verify the Windows Firewall is turned off.
• C. Configure the wireless network's SSID to be hidden.
• D. Enable file and printer sharing in the OS.

Correct answer: A

Explanation

The correct answer is A because without a DNS server configured, the clients will not be able to resolve domain names to IP addresses, leading to Internet access issues. Option B is less likely to be the issue since the technician can ping the default gateway, which suggests basic connectivity is functioning. Option C is unrelated to the connectivity problem and would not impact Internet access. Option D is also not relevant as file and printer sharing settings do not affect Internet connectivity.
