Networks and Laptops: Automatic Configuration vs profiles for telecommuters

A user telecommutes three days a week using a laptop computer. The user's Internet Service Provider at home requires a static IP address, subnet mask, and DNS server setting. The company network assigns addresses using DHCP.
You need to configure the user's computer so that the user can access the Internet when at home and the corporate network when at the office.
What should you do?

1. Create separate hardware profiles for the user at home and at work.
2. Create separate user profiles for the user at home and at work.
3. Enable automatic configuration. Add the ISP-defined settings to the Alternate Configuration tab.
4. >>Configure both IP configurations manually in Advanced TCP/IP settings.

Explanation : You should enable automatic configuration and add the ISP-defined settings to the Alternate Configuration tab. With this configuration, the computer first tries to find a DHCP server. If one cannot be found, the IP configuration on the Alternate Configuration tab is used.

You should not create separate user profiles for the user at home and at work. IP configuration settings are not defined in the user profile.

You should not create separate hardware profiles for the user at home and at work. The hardware profile limits the drivers that are loaded. It cannot be used to establish different IP configuration settings.

You should not configure both IP configurations manually in Advanced TCP/IP settings. Doing so would create a multi-homed network adapter, but the settings would not work correctly given the situation. Also, you want to be able to dynamically assign addresses when the user is connected to the company network, not manually assign the address.
