你是一台WINXP专业版电脑的管理员，这台电脑是一个Win2000域的成员。这个域包括一个企业认证权威（CA）。你使用电脑连接到Internet。六个月前，你付费给一家咨询公司要求电脑在线支持服务。这家咨询公司的Web站点为http：//www.tesTestKinging.com。现在你试图连接到这个Web站点再次使用支持服务。在那个Web页面出现以前，显示了一个对话框，让你选择一个认证才能使用链接。然而对话框的认证列表却是空的。因此你无法选择认证也就无法访问Web站点。在IE，你打开”Internet选项”对话框来选择认证，在”高级目的”列表出现了几个个人认证 你想连接到http：//www.tesTestKinging.com。你觉得怎么做？（） ["配置IE使”使用TLS 1.0”可用","在”信任发行商”列表里添加www.tesTestKinging.com作为服务器认证","联系这个支持公司获得认证并将它添加到个人认证列表里","从企业CA里获取一个认证","改变Internet区域的安全设置使”匿名登录”可用"]
