You have to accomplish this task and reduce the effect on the users to the least. So what action should you perform?

You are a database developer and you have about two years experience in creating business Intelligence (BI) by using SQL Server2008.

Now you are employed in a company named NaproStar which uses SQL Server2008. There are two servers in your company.
One is a production server and another one is a development server.
Now you’re in charge of a SQL Server 2008 Analysis Services (SSAS) database on a production server.
The database has a cube. New functionality has been added to the cube on a development server.

Now you receive an order from your company CIO, according to the requirement of the CIO, the new functionality has to be deployed from the development server to the production server.
You have to accomplish this task and reduce the effect on the users to the least. So what action should you perform?

A.
In order to accomplish this task, you should copy the appropriate files from the development server to the production server

B.
In order to accomplish this task, the Synchronize Database Wizard should be used.

C.
In order to accomplish this task, using Business Intelligence Development Studio (BIDS), modify the Target Server property to the production server. Then deploy the solution

D.
In order to accomplish this task, first the production database should be detached. Second, you should copy the appropriate files to the production server; at last you should attach the database on the production server.

Using the Synchronize Database Wizard
Synchronizing two SSAS databases is a common management task. For example, you might need to process a cube once on a dedicated staging server and then deploy it to loadbalanced
production servers. The traditional way to synchronize databases is to back up and restore the SSAS database, but this requires several steps and might take longer than you want. Instead, consider simplifying this task by using the Synchronize Database Wizard.

Understanding Database Synchronization
The output of the Synchronize Database Wizard is a single XMLA command named Synchronize.
You need to send this command to the target server whose objects need to be updated.
When the target server receives the Synchronize command, it forwards the command to the specified source server so that the target server can acquire a read lock on the source database.
Next, the target server obtains a list of source database metadata and data files.
Having received the fi les, the target server releases the read lock on the source database because the target server can complete the remaining tasks on its own. The target server compares the source fi les against the state of the target database and identifies the differences. Last, the target server applies the metadata and data differences to the target database to make it identical to its source counterpart.

IMPORTANT setting up security
Because copying the database metadata and data is a sensitive task, the Windows account under which the target SSAS server runs must have administrative rights to the source database.
When you connect to the source server in SSMS, you connect under your identity.
However, the target server executes the Synchronize command under its service account. If this is the Local System Windows account, the command will fail. To avoid this, confi gure
the target SSAS server to run under a domain account and grant that account administrative rights to the source database.

EXAM TIP
Suppose that you have a farm of production servers and you need to deploy the latest changes to each server. you want to avoid processing the SSAS database on each production
server because each cube would take very long to process. Instead, you decide to process the cube on a staging server and then synchronize each production server with the staging server. The Synchronize Database Wizard is designed specifically to handle this deployment model.
