You need to design a security strategy for the Web folders and files created by the consultants and the internal Web developers. What are two possible ways to achieve this goal？（）

A.Enable automatic certificate enrollment
B.Enforce smart card logons
C.Enable Encrypting File System （EFS） for offline files
D.Enable a screen saver password

A.Configure RRAS2 as a VPN server. Use Web enrollment to acquire computer certificates for both RRAS1 and RRAS2. Create demand-dial L2TP/IPSec connections on both RRAS1 and RRAS2. Configure dial-out credentials on both RRAS1 and RRAS2. Enable the Basic Firewall settings on RRAS1 and RRAS2
B.Configure RRAS2 as a VPN server. Create demand-dial L2TP/IPSec connections on both RRAS1 and RRAS2. Configure dial-out credentials on both RRAS1 and RRAS2. Configure static routes on both RRAS1 and RRAS2. Set the connection type to persistent on the demand-dial interface on both RRAS1 and RRAS2
C.Create a new OU named RRAS Servers in the boston.northwindtraders.com domain. Move RRAS1 into the RRAS Servers OU. On the Default Domain Policy Group Policy object （GPO）， edit the Secure Server （Require Security） IPSec policy. Configure the IPSec policy to use a certificate for authentication. Specify RRAS2 as the tunnel endpoint. Assign the IPSec policy.
D.Create a new OU named RRAS Server in the northwindtraders.com domain. Move the RRAS2 into the RRAS Servers OU. On the RRAS Servers OU create new Group Policy object （GPO） named IPSECPOL. In IPSECPOL create an IPSec policy and specify RRAS as the tunnel.

A.Open the ports for DNS， HTTP， HTTPS， Kerberos， RADIUS， LDAP， RPC endpoint mapper and client， and Server Message Block （SMB） over IP
B.Enable the Routing and Remote Access Basic Firewall. Open the ports for DNS， Kerberos， LDAP， Exchange RPCs， RADIUS， L2TP， and Internet Key Exchange （IKE）
C.Create a PPTP tunnel from ISA3 to the New York network
D.Create an L2TP/IPSec tunnel from ISA3 to the New York network
