After making a configuration change to an Apache web server, an administrator needs to reload the service. However, sudo access was only granted to the command. killall Which of the following commands should the administrator use to load the new configuration?

Question

Accepted Answer

A. sudo killall -HUP httpd Sending the `HUP` (Hang Up) signal to the `httpd` process, typically with `killall -HUP httpd`, instructs the Apache web server to gracefully reread its configuration files and apply changes without interrupting active connections. This is the standard method for reloading Apache's configuration without a full restart.

Answer

B. sudo killall -reload httpd The `-reload` option is not a standard signal name or recognized option for the `killall` command.

Answer

C. sudo killall -9 httpd Sending signal 9 (`KILL`) forces an immediate, ungraceful termination of the process, which can lead to data loss or service disruption, and does not allow for a configuration reload.

Answer

D. sudo killall -TERM httpd Sending signal 15 (`TERM`) requests a graceful shutdown of the process, which usually causes the service to exit rather than just reloading its configuration.
