Your network contains two standalone servers named Server1 and Server2 that have Active Directory Lightweight Directory Services (AD LDS) installed.
Server1 has an AD LDS instance.
You need to ensure that you can replicate the instance from Server1 to Server2.
What should you do on both servers?

Your network contains an Active Directory domain. The domain contains three domain controllers.
One of the domain controllers fails.
Seven days later, the help desk reports that it can no longer create user accounts. You need to ensure that the help desk can create new user accounts.
Which operations master role should you seize?

Your network contains an Active Directory forest. The forest contains two domains named contoso.com and woodgrovebank.com.
You have a custom attribute named Attibute1 in Active Directory. Attribute1 is associated to User objects.
You need to ensure that Attribute1 is replicated to the global catalog.
What should you do?

Your network contains an Active Directory domain. The functional level of the domain is Windows Server 2003. The domain contains five domain controllers that run Windows Server 2008 and five domain controllers that run Windows Server 2008 R2.
You need to ensure that SYSVOL is replicated by using Distributed File System Replication (DFSR).
What should you do first?

Your network contains a single Active Directory domain that has two sites named Site1 and Site2. Site1 has two domain controllers named DC1 and DC2. Site2 has two domain controllers named DC3 and DC4.
DC3 fails.
You discover that replication no longer occurs between the sites. You verify the connectivity between DC4 and the domain controllers in Site1.
On DC4, you run repadmin.exe /kcc.
Replication between the sites continues to fail.
You need to ensure that Active Directory data replicates between the sites.
What should you do?

Your company has a main office and a branch office.
You discover that when you disable IPv4 on a computer in the branch office, the computer authenticates by using a domain controller in the main office. You need to ensure that IPv6-only computers authenticate to domain controllers in the same site.
What should you do?

You need to ensure that domain controllers only replicate between domain controllers in adjacent sites.
What should you configure from Active Directory Sites and Services?

Your network contains an Active Directory forest. The forest contains multiple sites. You need to enable universal group membership caching for a site.
What should you do?

Your company has a main office and 50 branch offices. Each office contains multiple subnets. You need to automate the creation of Active Directory subnet objects.
What should you use?

Your company has a main office and a branch office. The main office contains two domain controllers.
You create an Active Directory site named BranchOfficeSite. You deploy a domain controller in the branch office, and then add the domain controller to the BranchOfficeSite site.
You discover that users in the branch office are randomly authenticated by either the domain controller in the branch office or the domain controllers in the main office. You need to ensure that the users in the branch office always attempt to authenticate to the domain controller in the branch office first.
