A salesperson in your organization spends most of her time traveling between customer sites. After a customer visit, she must complete various managerial tasks, such as updating your organization's order database.
Because she rarely comes back to the home office, she usually accesses the network from her notebook computer using Wi-Fi access provided by hotels, restaurants, and airports.
Many of these locations provide unencrypted public Wi-Fi access, and you are concerned that sensitive data could be exposed. To remedy this situation, you decide to configure her notebook to use a VPN when accessing the home network over an open wireless connection.
Which key steps should you take when implementing this configuration? (Select two.)
Configure the browser to send HTTPS requests directly to the Wi-Fi network without going through the VPN connection.
Configure the browser to send HTTPS requests through the VPN connection.
Configure the VPN connection to use MS-CHAPv2.
Configure the VPN connection to use PPTP.
Configure the VPN connection to use IPsec.
Configure the browser to send HTTPS requests through the VPN connection.
Configure the VPN connection to use IPsec.
