To answer this question, you need to understand how Linux resolves hostnames.
Linux uses the /etc/host.conf file to resolve hostnames. This file contains the configuration settings for the hostname resolution process.
Let's go through each option to understand why it is correct or incorrect:
Option A) /etc/hostname.conf - This option is incorrect because Linux does not use the /etc/hostname.conf file to resolve hostnames.
Option B) /etc/dns.conf - This option is incorrect because Linux does not use the /etc/dns.conf file to resolve hostnames.
Option C) /etc/host.conf - This option is correct. Linux uses the /etc/host.conf file to resolve hostnames. This file contains the configuration settings for the hostname resolution process.
Option D) /etc/resolve.conf - This option is incorrect. While the /etc/resolve.conf file exists in Linux systems, it is used to configure the DNS (Domain Name System) resolver, not for hostname resolution.
The correct answer is C) /etc/host.conf. This option is correct because Linux uses the /etc/host.conf file to resolve hostnames.
