Question:
A business traveler connects to a wireless network with open authentication. What should the traveler do to secure confidential data when connecting to the business services?

Connect with a VPN.
Change the network location profile to public.
Change the Windows firewall settings.
Manually configure an IP address, subnet mask, and default gateway.

Explanation: A VPN is used to form a secure tunnel across a public network. This technology allows users to communicate over an insecure network and yet keep data confidential. Changing the network location profile will modify firewall settings on a computer but not increase the confidentiality of data crossing a network. Modifying the IP address, subnet mask, and default gateway will not change the confidentiality of data transmitting on a network.
