CompTIA Network+ (N10-008) — Question 575

A user took a laptop on a trip and made changes to the network parameters while at the airport. The user can access all internet websites but not corporate intranet websites. Which of the following is the most likely cause of the issue?

Answer options

• A. Duplicate IP address
• B. Duplicate SSID
• C. Incorrect DNS
• D. Incorrect subnet mask

Correct answer: C

Explanation

The most likely reason for the user being unable to access corporate intranet websites is due to an Incorrect DNS setting, which prevents the laptop from resolving the internal addresses. A Duplicate IP address could cause connectivity issues, but since the user can access internet sites, that is less likely. A Duplicate SSID and Incorrect subnet mask would not specifically impact intranet access while allowing internet access.
