A portable computer that runs Windows 8 uses a mobile broadband connection for the corporate wireless
network.
The computer also has a wired corporate network connection. The computer successfully downloads Windows
updates when connected to either network.
You need to ensure that the computer automatically downloads updates by using Windows Update only while
connected to the wired corporate networkconnection.
What should you do?

A.

D.

You can also set particular networks as a metered connection, which will then disable Windows Update from
downloading updates (except for critical security patches) and possibly disable or reduce data usage from
other Microsoft and non-Microsoft applications as well.
