Question

Your company has a main office and a new branch office. The network consists of one Active directory domain. The branch office contains two member servers that run Windows Server 2008 R2. One of the servers is configured as a file server that hosts shared folders. An administrator in the branch office is responsible for maintaining the servers. You have a single DNS zone that is hosted on a DNS server located in the main office. A wide area network (WAN) link between the branch office and the main office is unreliable. You need to recommend a network services solution for the new branch office. The solution must meet the following requirements: - Users must be able to log on to the domain if a WAN link fails. - Users must be able to access file shares on the local server if a WAN link fails. - Branch office administrators must be prevented from initiating changes to Active Directory. - Branch office administrators must be able to make configuration changes to the servers in the branch office. What should you recommend?

Options

  • APromote the member server to a domain controller and add the branch office administrators
  • BPromote the member server to a read-only domain controller (RODC) and add the branch
  • CPromote the member server to a read-only domain controller (RODC) and configure the
  • DPromote the member server to a domain controller and configure the DNS role.

Explanation

To ensure that the users in the branch office are able to log on to the domain even if the WAN link fails, you need to promote the member server to a read-only domain controller (RODC) because the RODC works as a domain controller and allow log in to the domains except allowing modifications and changes to the Active directory domain. Delegating administrative rights to the local branch office administrator after promoting a member server to a RODC will make sure that branch office administrator is not allowed to initiate any changes to Active Directory but should be allowed to make configuration changes to the servers in the branch office. Configuring the DNS role to the member server, will ensure that the users are allowed to access file shares on the local server in the absence of the WAN link. Without name resolution and the other services that are provided by DNS servers, client access to remote host computers would be prohibitively difficult. DNS servers need to be configured because in intranets computer users rarely know the IP addresses of computers on their local area network (LAN). 433bd018f66d1033.mspx?mfr=true
