Correct Answer: A
Explanation/Reference:
A metadata repository is used as a common repository for managing metadata of different applications.
Many applications use the MDS repository to manage their metadata. Each deployed application uses a logical partition in metadata repository. This logical partition also helps in maintaining the metadata lifecycle. Before deploying an application, you create a partition for it in MDS repository. This command creates a partition with the given name in the specified repository.
Note: The Metadata repository provides a centralized holding area for a great deal of SOA related information that will be utilized at design time to construct additional services and applications. The repository also provides the primary means for service discovery. In many ways, the service repository can be utilized as the center point for service oriented design.
