Which error indicates that a domain name could not be resolved?

• A. DNS_PROBE_FINISHED_NXDOMAIN is shown when a domain name cannot be resolved.
• B. ERR_NETWORK_CHANGED is shown when the network changes.
• C. 500 Internal Server Error is shown when the server fails.
• D. 302 Found is shown when a page is moved temporarily.

Answer: (A)

When a domain name cannot be translated into an IP address, the browser shows a DNS-related error. This happens during the DNS resolution step, where your device asks a DNS server to translate the domain into a numeric address. DNS_PROBE_FINISHED_NXDOMAIN specifically means the DNS lookup finished but could not find the domain—it's either mistyped, the domain doesn’t exist, or there’s no DNS record for it. That’s why this error is the indicator that a domain name could not be resolved. The other messages point to different issues: ERR_NETWORK_CHANGED occurs when your network configuration or connection changes; a 500 Internal Server Error means the server you’re talking to had a problem serving the page; and 302 Found is an HTTP redirect indicating a page moved temporarily, not a failure to resolve a domain.
