考题 You are a help desk technician for your company. Susan is an executive. Because Susan travels frequently, she uses a Windows XP Professional portable computer that has a smart card reader. Susan asks you to configure her computer so that she can dial in to the company network when she is out of the office. Company security policy states that dial-in users must use a smart card when they connect to the network, and that the users must use the strongest form of data encryption possible. Company security policy also states that client computers must disconnect if the Routing and Remote Access server does not support both smart card authentication and the strongest possible authentication. You need to configure the dial-up connection properties on Susan’s computer to dial in to the company network. Your solution must ensure that company security policies are enforced. Which three actions should you perform?（） A、Select the Advanced (custom settings) security option.B、Select the Require data encryption check box. C、Select the Typical (recommended settings) security option. D、Select the Use smart card item from the Validate my identity as follows list.E、Select the Maximum strength encryption item from the Data encryption list.F、Select the Extensible Authentication Protocol (EAP) option, and select Smart Card or other Certificate from the EAP list.
