Homework Help: Questions and Answers: What does the DNS_PROBE_FINISHED_NXDOMAIN error indicate?
A) The server is temporarily unavailable
B) The domain name does not exist
C) The connection was reset
D) The URL is incorrectly formatted
Answer
First, let’s understand the error message:
- DNS: Domain Name System
- PROBE: An attempt to reach or test something
- FINISHED: The attempt has completed
- NXDOMAIN: Non-Existent Domain
The Domain Name System (DNS) is responsible for translating human-readable domain names (like www.fdaytalk.com) into IP addresses that computers use to communicate with each other.
When you see the DNS_PROBE_FINISHED_NXDOMAIN error, it indicates a DNS-related problem. Let’s now analysis given options to see which fits best.
Given Options: Step by Step Answering
a) The server is temporarily unavailable
- This would occur when the website’s server is down or unreachable due to technical issues or maintenance.
- This is not the correct answer. Temporary unavailability would typically result in a different error.
b) The domain name does not exist
- This means that the DNS system is unable to find an IP address corresponding to the domain name entered. Either the domain has not been registered, or there’s a typo in the domain name.
- This is the correct answer. Non-existent domain matches exactly with what NXDOMAIN means.
c) The connection was reset
- A connection reset happens when the connection between your device and the server is unexpectedly interrupted.
- This is not the correct answer. A connection reset would be a different type of error, not DNS-related.
d) The URL is incorrectly formatted
- An incorrectly formatted URL might result in a “404 Not Found” error or a “Bad Request” error but not DNS_PROBE_FINISHED_NXDOMAIN.
- This is not the correct answer. An incorrectly formatted URL would likely result in a different error message.
Final Answer
Based on the above analysis, the correct answer is:
B) The domain name does not exist
This error (DNS_PROBE_FINISHED_NXDOMAIN) occurs when the DNS server cannot find the requested domain name in its records, indicating that the domain name doesn’t exist or hasn’t been registered.
