In organizations where availability is a primary concern, the MOST critical success factor of the
patch management procedure would be the:

A.
testing time window prior to deployment.

B.
technical skills of the team responsible.

C.
certification of validity for deployment.

D.
automated deployment to all the servers.

Explanation:

Having the patch tested prior to implementation on critical systems is an absolute prerequisite
where availability is a primary concern because deploying patches that could cause a system to
fail could be worse than the vulnerability corrected by the patch. It makes no sense to deploy
patches on every system. Vulnerable systems should be the only candidate for patching. Patching
skills are not required since patches are more often applied via automated tools.
