Question

A Linux administrator wants to resolve a remote server name locally. When of the following files should the administrator modify?

Options

A/etc/hosts
B/etc/resorv.conf
C/etc/network
D/ett/rpc

Explanation

To resolve a remote server name locally without relying on DNS servers, the /etc/hosts file can be modified to map IP addresses to hostnames.

Common mistakes.

B. /etc/resolv.conf specifies the DNS servers that the system should use for name resolution, but it does not directly define static local hostname mappings.
C. /etc/network is a directory that typically contains network interface configuration files, not files for local hostname resolution.
D. /etc/rpc is related to Remote Procedure Call (RPC) services and their program numbers, which is unrelated to hostname resolution.
