You are designing a strategy to optimize the DNS name resolution for the satellite offices that connect to the branch offices by using ISDN lines. What should you do?（）

A.Increase the replication interval between sites.
B.Use SMTP as the transport protocol for replication.
C.Create site links to represent the physical topology.  
D.Disable the Knowledge Consistency Checker (KCC) and manually configure site replication.

A.Import the user accounts as inetOrgPerson objects.  
B.Import the user accounts into Active Directory by using the Ldifde command-line tool. 
C.Export all user accounts from the UNIX servers to a text file.  
D.Export all user accounts and their passwords from the UNIX servers to a text file. Encrypt this file to achieve extra security.  
E.Assign random passwords to each user object, and securely distribute the password to the users.  
F.Create the same strong password for each user object, and require users to change their passwords at first logon. 

A.Create an organizational unit (OU) for all users who log on to any of the NewApp servers.
B.Create an organizational unit (OU) named NewApp Users for the NewApp users.
C.Create an organizational unit (OU) named NewApp Servers for the NewApp servers.
D.Create a Group Policy object (GPO) for the NewApp Users OU to enforce the use of IPSec.
E.Create a global group for all NewApp servers. Add this group to the NewApp Servers OU.
F.Create a Group Policy object (GPO) for the NewApp Servers OU to enforce the use of smart cards.
