Which of the following is a requirement for Falcon to be supported on a server?

For Falcon to be supported on a server, it is essential to use an operating system version that meets CrowdStrike's compatibility and support criteria. Windows Server 2008 R2 with Service Pack 1 is a supported version as it includes critical updates that enhance security, stability, and performance. Service packs often contain important fixes and improvements that are necessary for software compatibility and optimal functioning, making this option valid for the CrowdStrike Falcon deployment.

In contrast, Windows Server 2003 R2 and Windows Server 2008 without Service Pack do not meet the current support criteria. Windows Server 2003 is outdated and no longer receives updates from Microsoft, thus not offering a secure or stable environment for Falcon. Additionally, while Linux-based servers can be supported, they are not the sole requirement for Falcon’s deployment, making the other options less appropriate. Therefore, Windows Server 2008 R2 with Service Pack 1 is the proper choice for ensuring Falcon’s functionality and alignment with the supported operating systems.
