Which file is an executable used to troubleshoot DNS issues?
- /etc/hosts
- /usr/bin/nslookup
- /bin/resolve
- /sys/domain/lookup
| Explanation & Hint:
The executable used to troubleshoot DNS (Domain Name System) issues on a Linux system is typically /usr/bin/nslookup or a similar utility like dig. These tools allow you to query DNS servers to obtain information about domain names, IP addresses, and various DNS records, which is essential for troubleshooting and diagnosing DNS-related problems.
The other paths and files mentioned do not serve as primary DNS troubleshooting tools. The /etc/hosts file is used for local hostname-to-IP address resolution, and the other paths mentioned are not standard utilities for DNS troubleshooting. |
