An extremely destructive worm has been reported by major vendors and patches are available to
prevent security breaches. According to BEST practices, how should security patches and security
hot fixes be applied?

A.
assess the need for particular patches or hot fixes and if required, test them prior to installation
on a UAT (User Acceptance Testing) system

B.
check to see if the security patches or hot fixes are needed; apply the appropriate patches or
hot fixes immediately to the most vulnerable servers

C.
immediately apply all patches that come from the vendor

D.
check to see if the security patches or hot fixes are needed; apply the appropriate patches or
hot fixes immediately to non-critical production servers
