You are tasked with deploying the Falcon sensor on a group of Windows devices. Which of the following prerequisites must be ensured before…

CrowdStrike’s official Windows Sensor Deployment Guide states that the installer must be executed “from an account with local Administrator privileges (or elevated with an Administrator token).” This is the only prerequisite that must be satisfied on every Windows host before installation begins. The sensor can coexist with third-party antivirus, needs much less than 100 MB of disk, and communicates outbound over TCP 443 without requiring Windows Firewall to be disabled.

B. Falcon is designed to run alongside existing AV; no vendor guidance requires AV removal.

C. Vendor documents list sensor size ≈40 MB; no minimum-disk prerequisite of 100 MB is specified.

D. Sensor uses outbound HTTPS (TCP 443); Windows Firewall may remain enabled with default outbound allow.
