You have a System Center Configuration Manager 2007 environment. You create a new child site named S01 at a new branch office. You deploy the management point and the software update point.

Computers in the S01 site are able to detect Microsoft security updates, but the computers are not able to install the updates successfully.

You need to configure the S01 site so that client computers can install security updates.

What should you do?

A.
Configure the software update point to synchronize from an upstream update server.

B.
Configure a distribution point for S01. Send the update packages to the distribution point.

C.
Configure the system health validator point. Enable the Advertised Programs client agent.

D.
Enable software update point client installation. Configure the Network Access account for S01.
