   A company has 50 servers in a private cloud. The security team needs to apply a critical patch immediately.

   • BUse local automation on each server, with a script that runs at a scheduled time.
   • CUse a push method from the central server, sending the patch and install command to servers in the required order.
   • DUse a declarative configuration that defines the desired patch level for all servers.
