What is a common administrative task when managing system processes related to user applications during boot?

Starting necessary services like web servers is a critical administrative task during the boot process as it ensures that the required applications and services are operational when the system becomes available to users. This process often involves initializing various system and application services that are set to launch automatically at system start-up. For instance, if you are running a web server, it needs to be active for users to access hosted websites or applications.

Other choices, while important in their own right, do not typically relate directly to the immediate management of user applications during the boot sequence. Enabling antivirus mechanisms is generally performed after booting and involves maintaining security rather than directly addressing user application functionality. Configuring network settings, while crucial, is also more about establishing connectivity than specifically managing applications. Adjusting graphical settings is usually a task aimed at user experience and interface preferences, rather than a fundamental requirement for the functioning of user applications. Each of these tasks is important in system administration, but starting services directly correlates to ensuring applications are available post-boot, which is the primary focus during that phase.
