Question
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?
- A. Hosts file Correct
- B. Self-signed certificate
- C. Nameserver record
- D. IP helper
Explanation
When only one user resolves a name to the wrong IP address, the cause is local to that machine, and the hosts file is checked before DNS, so an incorrect entry there overrides the correct answer from the name servers. A wrong nameserver record would affect every user who relies on that DNS zone, not just one. A self-signed certificate causes a browser trust warning, not an incorrect name resolution. An IP helper forwards DHCP broadcasts across subnets and has nothing to do with resolving URLs.
