Which of the following should the technician check FIRST?

Each time a user tries to go to the selected web search provider, a different website opens.

Which of the following should the technician check FIRST?
A . System time
B . IP address
C . DNS servers
D . Windows updates

Answer: C

Explanation:

When a user experiences unexpected or erratic behavior while browsing the internet, it could be caused by the DNS servers. DNS translates human-readable domain names (like google.com) into IP addresses, which computers can use to communicate with web servers. If the DNS servers are not functioning correctly or have been compromised, it can result in the browser being redirected to unintended websites.
