After a recent outage going unnoticed, an administrator has been tasked to configure monitoring for the Linux-based and Windows-based host operating systems in a hybrid cloud. Which of the following…

Syslog is the standard logging daemon on Linux-based hosts responsible for collecting system and application events and forwarding them to a centralized log management or monitoring platform; without it running, log-based monitoring for Linux hosts cannot function.

Cron is the Linux task scheduler used by monitoring agents and scripts to execute recurring health checks, metric collection jobs, and automated reporting; if Cron is not running, all scheduled monitoring tasks on Linux hosts will fail to execute.

Web services are not a prerequisite for host-level OS monitoring; monitoring agents communicate via dedicated agent protocols or syslog rather than HTTP, making web services irrelevant to this task.

Task Manager is a Windows interactive process viewer and diagnostic tool, not a background service, so it cannot be configured as a dependency or confirmed as a service for centralized monitoring purposes.

WMI (Windows Management Instrumentation) is a Windows-specific data collection framework and does not apply to the Linux-based hosts in the hybrid environment, making it inapplicable as a prerequisite for monitoring both OS types.
