To install the Falcon sensor quietly without restarting, which option should be used in the command?

To install the Falcon sensor quietly without restarting, the command option that should be used is the one that prevents a reboot after the installation process, which is represented by /norestart. This option allows the installation to complete without prompting for a system restart, making it suitable for environments where uptime is critical, or the system is actively in use.

Utilizing the /norestart option effectively manages system stability and user experience, allowing the Falcon sensor to be deployed seamlessly. In contrast, the other options may either not exist or may have different implications. For instance, /quietmode and /silentinstall could refer to modes that suppress user interface prompts but do not specifically indicate whether a reboot is required after installation. Similarly, /no-reboot generally serves the same purpose as /norestart, but in this context, the preferred option is explicitly defined as /norestart, aligning with the best practices for a Falcon sensor installation without interruptions.
