You are designing a Windows Azure application that will process images.
The maximum size of an image is 10 MB.
The application includes a web role that allows users to upload images and a worker role with multiple instances that processes the images.
The web role communicates with the worker role by using a Windows Azure Queue.
You need to recommend an approach for storing images that minimizes storage transactions.
What should you recommend?

You are designing a Windows Azure application.
The application includes two web roles and three instances of a worker role.
The web roles will send requests to the worker role through one or more Windows Azure Queues.
You have the following requirements:

– Ensure that each request is processed exactly one time.
– Minimize the idle time of each worker role instance.
– Maximize the reliability of request processing.

You need to recommend a queue design for sending requests to the worker role.
What should you recommend?

You are designing a Windows Azure application.
The application includes a web role and a worker role that communicate by using a Windows Azure Queue.
The worker role processes each message within 10 seconds of retrieving it from the queue.
The worker role must process each message exactly one time.
If a process does not complete, the worker role must reprocess the message.
You need to recommend an approach for the worker role to manage messages in the queue.

You are planning the migration of a Microsoft SQL Server 2008 database to SQL Azure.
You need to recommend an approach for ensuring that database connectivity does not degrade.
Which two actions should you recommend?
(Each correct answer presents part of the solution. Choose two.)

A Windows Azure application retrieves data from SQL Azure.
You need to recommend an approach for improving application query performance.
What should you recommend?

An application uses Windows Azure Table storage.
The application uses five tables.
One table used by the application is approaching the limit for storage requests per second.
You need to recommend an approach for avoiding data access throttling.
What should you recommend?

A Windows Azure application stores data in a SQL Azure database.
The application will start an operation that includes three insert statements.
You need to recommend an approach for rolling back the entire operation if the connection to SQL Azure is lost.
What should you recommend?

You are designing a Windows Azure application that will store data in two SQL Azure databases.
The application will insert data in both databases as part of a single logical operation.
You need to recommend an approach for maintaining data consistency across the databases.
What should you recommend?

An application connects to a SQL Azure database.
The application occasionally loses the connection to the SQL Azure database.
You need to recommend an approach for reliably completing data access operations.
What should you recommend?

You are designing an application that will use Windows Azure Table storage to store millions of data points each day.
The application must retain each day’s data for only one week.
You need to recommend an approach for minimizing storage transactions.
