You are troubleshooting a performance issue on an Oracle Linux 8 web server. You suspect that the system is paging heavily to swap, causing latency. Which specific `sar` command and column would best confirm that pages are being actively swapped in and out of disk, rather than just normal memory allocation activity?
An administrator needs to analyze the boot time of an Oracle Linux 8 server to identify which services are slowing down the startup process. Which command provides a hierarchical view of the critical chain of units, highlighting the time each unit took to initialize and which units delayed the boot?
You are managing an Oracle Linux 8 system and need to persistently modify a kernel parameter related to network performance. You want to ensure this setting survives reboots and takes precedence over default system settings. Which is the recommended location to create a new configuration file for this parameter?
A critical application requires the `xfs` filesystem on `/dev/mapper/data_vg-app_lv` to be expanded while mounted and online. The underlying logical volume has already been extended. Which command must be run to resize the filesystem to occupy the newly available space?
You have configured a custom service listening on TCP port 9090. SELinux is in Enforcing mode, and the service fails to bind to the port. You have identified that the port type `http_port_t` is appropriate for this service. Which command persistently adds port 9090 to the `http_port_t` SELinux policy?
A security audit requires that the `fapolicyd` service (File Access Policy Daemon) is configured to block execution of any untrusted binaries. After installing the package, what is the correct sequence of steps to enable the service and ensure it starts protecting the system immediately?
You are creating a systemd unit file for a Podman container that needs to start automatically at boot. You have created the container named `web_app`. Which command generates a systemd unit file that can manage this container using `runc` directly or through Podman, and handles container restarts properly?
