• C

• D

Explanation

The /etc/hosts file is the correct location for static, local hostname-to-IP address mappings. It is consulted before DNS (depending on /etc/nsswitch.conf configuration) and is ideal for isolated environments. The administrator would add 127.0.0.1 localhost and 192.168.192.12 database01.comptia.org to this file. /etc/nsswitch.conf controls the order of name resolution sources but does not contain address mappings. /etc/dhcpd.conf is for configuring a DHCP server, not local name resolution. /etc/network is a network interface configuration file (Debian/Ubuntu), not used for hostname mapping.
