单项选择题You are designing a Windows Azure application.  The application will include occasionally connected clients that reference data stored in Windows Azure Blob storage.  The clients will be able to add data while disconnected.  You need to recommend an approach for synchronizing offline client data with Windows Azure Blob storage.  What should you recommend？（）

A. Use SQL Azure Data Sync.
B. Use the Microsoft Sync Framework.
C. Use Windows Azure Blobstorage snapshots.
D. Use the Microsoft SQL Server replication component.

单项选择题You are designing a strategy for synchronizing a SQL Azure database and multiple remote Microsoft SQL Server 2008 databases.  The SQL Azure database contains many tables that have circular foreign key relationships.  You need to recommend an approach for ensuring that all changes in the remote databases synchronize with the SQL Azure database.  What should you recommend？（）

A. Use SQLAzure Data Sync Service.
B. Use SQL Server replication.
C. Use SQL Server backup and restore.
D. Use SQL Server database snapshots.

单项选择题You are designing a Windows Azure application that will allow for the processing of image files. Images will be processed in batches by remote applications running on multiple servers.  The application must meet the following requirements：   - Remain operational during batch-processing operations. - Allow users to roll back each image to previous versions.    Each remote application must have exclusive access to an image while processing it. You need to recommend an approach for storing the images.  What should you recommend？（）

A. Store the images in a Windows Azure Queue.
B. Store theimages in Windows Azure Blob storage.
C. Store the images in Windows Azure Table storage.
D. Store images in a single Windows Azure Drive attached to the web role.

单项选择题You are designing a web service that will be hosted in Windows Azure.  The web service will accept and store structured and semi-structured data. The web service must meet the following requirements：   - Update all data within a single transaction.  - Enforce the data structure for structured data within the data store.    You need to recommend an approach for storing the data.  What should you recommend？（）

A. Use Windows Azure Queues.
B. Use a single SQL Azure database.
C. Use a single Windows Azure Drive.
D. Use Windows Azure Table storage.
