CompTIA Linux+ XK0-006 (V8) Practice Question

After adding the line

192.168.50.10 intranet

to /etc/hosts on a CentOS Stream 9 server, an administrator finds that running ping intranet still resolves to 192.168.50.20, the address supplied by the corporate DNS service. The hosts database line in /etc/nsswitch.conf currently reads:

hosts: dns files mdns4

The administrator wants the system to honor the /etc/hosts entry first while still falling back to DNS and Multicast DNS if necessary. Which change will accomplish this goal?

  • Replace "dns" with "bind4" in the hosts line so it reads: hosts: files bind4 mdns4

  • Edit /etc/nsswitch.conf so the line reads: hosts: dns mdns4 files

  • Add the directive "order hosts,bind" to /etc/host.conf and leave nsswitch.conf unchanged

  • Edit /etc/nsswitch.conf so the line reads: hosts: files dns mdns4
