You need to design a security strategy for the DHCP servers in the Seattle office. Which two actions should you perform？（）

A.Configure and publish a certificate template that is suitable for S/MIME, Deploy a Group Policy object （GPO） so that a certificate that is based on this template is automatically issued to all domain users
B.Specify Group Policy objects （GPOs） and IPSec policies that require all client computers to use Kerberos authentication to connect to mail servers
C.For each mail server， acquire an SSL server certificate from a commercial CA whose root certificate is already trusted
D.Require IPSec encryption on all TCP connections that are used to send or receive e-mail messages

A.Deploy a Windows Server 2003 computer running SUS in the test network. Deploy SUS servers in each child domain to download administrator-approved updates from the test network SUS server
B.Deploy a Windows Server 2003 computer running SUS in the test network Use autoupdate policies in each child domain to download and deploy updates from the test network SUS server
C.Install MBSA on a Windows Server 2003 computer in the network network. Deploy MBSA as a Windows Installer package to all computers in the child domains， and configure MBSA to scan for updates from the server in the test network
D.Install IIS on a Windows Server 2003 computer in the test network. Create a Web site named Updates on this server. Configure an autoupdate policy in each child domain to download and deploy updates from the Updates Web site

A.Deploy an offline enterprise root CA in the corp.woodgrovebank.com domain. Deploy subordinate enterprise root CAs in each child domain. Install Internet Authentication Service （IAS） on one member server in the la.corp.woodgrovebank.com domain and one member server in the den.corp.woodgrovebank.com domain
B.Deploy an enterprise root CA in each domain. Install Internet Authentication Service （IAS） on a member server in the corp.woodgrovebank.com domain. Install the Routing and Remote Access service on a member server in each child domain， and configure these servers as RADIUS clients
C.Enroll and deploy user certificates to all administrators in each domain. Enroll and deploy computer certificates to all portable computers that have wireless network adapters. Configure each portable computer to use Protected EAP （PEAP） for authentication
D.Enroll and deploy computer certificates to all portable computers that have wireless network adapters. Configure each portable computer to use EAP-MS-CHAP v2 for authentication. Configure each portable computer to connect to the Internet Authentication Service （IAS） server
