What is the purpose of the nsswitch.conf file?
Correct Answer: A
The nsswitch.conf file is a configuration file that determines the sources and the order of the sources that are queried for various system databases, such as user information, group information, host names, network services, and more. The C library uses this file to look up various system information when a program or a command requests it. For example, when a user logs in, the C library will use the nsswitch.conf file to determine where to find the user's password, whether it is in the local /etc/passwd file, or in a remote LDAP server, or both. The nsswitch.conf file allows the system administrator to configure the system databases in a flexible and modular way. Reference:
