You are an Enterprise administrator for contoso.com. The company has a head office and two branch offices that connect with each other by using a WAN link. The corporate network of the company consists of a single Active Directory domain.
All the servers in the domain run Windows Server 2008 and all client computers run Windows Vista. Each office contains a file server and the office users use the local file server to store data on it. The users also have access to data from the other offices.
You have been assigned that task to plan a data access solution and ensure that folders that are stored on the file servers must be available to users in both offices and users must be able to access all files even when the WAN link fails. Besides this the network bandwidth usage between offices is minimized.
Which of the following options would you choose to accomplish the desired goal?
A.
Implement Distributed File System Replication (DFSR) on the file servers in both the offices.
B.
On one of the servers, configure Distributed File System (DFS) and on the other, configure the Background Intelligent Transfer Service (BITS).
C.
Configure File Server Resource Manager (FSRM) and File Replication Service (FRS) on both the servers
D.
On one of the servers, configure File Server Resource Manager (FSRM) and on the other configure File Replication Service (FRS).
E.
None of the above
Explanation:
To plan a data access solution and ensure that folders that are stored on the file servers must be available to users in both offices and users must be able to access all files even when the WAN link fails, you need to implement Distributed File System Replication (DFSR) on the file servers in both the offices.
Rather than having every user in your organization access their files from the same server, you can distribute the user workload across multiple DFS replicas rather than over burdening a single server.
DFS Replication is an efficient, multiple-master replication engine that you can use to keep folders synchronized between servers across limited bandwidth network connections. It replaces the File Replication Service (FRS) as the replication engine for DFS Namespaces, as well as for replicating the SYSVOL folder in domains that use the Windows Server2008 domain functional level.
DFS Replication service has a totally revamped replication engine that uses a new replication algorithm called Remote Differential Compression (RDC). This new algorithm replicates only the changes to files and not the files themselves, which means that DFS now works much better over slow WAN links than before. In addition, the new replication engine supports bandwidth throttling and replication scheduling, plus it operates on a multimaster replication model.
