CompTIA Network+ (N10-009) — Question 489

A user is unable to navigate to a website because the provided URL is not resolving to the correct IP address. Other users are able to navigate to the intended website without issue. Which of the following is most likely causing this issue?

Answer options

• A. Hosts file
• B. Self-signed certificate
• C. Nameserver record
• D. IP helper

Correct answer: A

Explanation

The most likely cause of the issue is the Hosts file, which can override DNS settings and map URLs to incorrect IP addresses. A self-signed certificate pertains to security and encryption, while a Nameserver record is related to DNS but is not the issue here, as other users can access the site. An IP helper is used for directing broadcasts but does not affect URL resolution.
