CompTIA A+ Core 2 (220-1202) — Question 100

When a corporate laptop is connected to the company network, the laptop is able to reach external websites. However, when the laptop tries to reach any internal websites the following error message appears:

Hmm... Cannot reach this page.

Which of the following should a technician configure?

Answer options

• A. Subnet mask
• B. DNS settings
• C. Default gateway
• D. DHCP

Correct answer: B

Explanation

The correct answer is B because DNS settings are responsible for translating internal website names to their corresponding IP addresses. If the DNS settings are incorrect, the laptop will not be able to resolve internal website addresses, leading to the error message. The other options, while important for network configuration, do not directly relate to the ability to access internal website names.
