CompTIA A+ Core 2 (220-1102) — Question 361

A 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 the technician check next to resolve the issue?

Answer options

• A. Verify the DNS server settings
• B. Turn off the Windows firewall
• C. Confirm the subnet mask is correct
• D. Configure a static IP address

Correct answer: A

Explanation

The correct answer is A because DNS server settings are crucial for resolving domain names to IP addresses, which is necessary for Internet access. Options B and C may be relevant but do not directly address the issue of name resolution, while option D is unnecessary since the technician already has a valid IP address from DHCP.
