Which of the following is NOT an advantage to an automated patch update service?

a$.$ Downloading patches from a local server instead of using the vendor's online update service can save bandwidth and time because each computer does not have to connect to an external server.

b$.$ Users can disable or circumvent updates just as they can if their computer is configured to use the vendor's online update service.

c$.$ Specific types of updates that the organization does not test, such as hotfixes, can be automatically installed whenever they become available.

d$.$ Administrators can approve or decline updates for client systems, force updates to install by a specific date, and obtain reports on what updates each computer needs.
