Which of the following are valid options for scaling queues? (Choose three.)

DRAG DROP
You are developing an ASP.NET Web API that runs as an Azure Web App. The App uses Azure Active
Directory (Azure AD) business-to-business (B2B) for authentication and authorization.
The application contains an ASP.NET Web API controller to retrieve test results. The directory contains the
Tester Azure AD group as shown below.

You need to ensure that the Get controller method is available only to members of the Tester group.
What should you do? To answer, drag the appropriate code segments to the correct locations. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Select and Place:

Which of the following are valid differences between page blobs and block blobs? (Choose two.)

You are designing a Windows Azure application.
The application will store data in Windows Azure Blob storage.
Many of the application services will be interdependent.
You need to recommend an approach for optimizing the performance of the application.
What should you recommend? accounts and hosted services to the same geographical grouping within a specified region. Each affinity group is associated with a Windows Azure subscription, and can be used by multiple storage accounts and hosted services for that subscription. subscription.

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? streaming. Page blobs, which are optimized for random read/write operations and which provide the ability to write to a range of bytes in a blob.

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.
What should you recommend?

You are designing a Windows Azure application that will generate events for multiple clients.
Client web services might be behind NAT gateways.
You need to recommend an approach that will allow you to broadcast the events to clients.
What should you recommend? communication, large-scale event distribution, naming, and service publishing. The Service Bus provides connectivity options for Windows Communication Foundation (WCF) and other service endpoints including network address translation (NAT) boundaries, or bound to frequently-changing, dynamically-assigned IP addresses, or both. The Service Bus provides both “relayed” and “brokered” messaging capabilities. In the relayed messaging pattern, the relay service supports direct one-way messaging, request/response messaging, and peer-to- peer messaging. Brokered messaging provides durable, asynchronous messaging components such as Queues, Topics, and Subscriptions, with features that support publish-subscribe and temporal decoupling: senders and receivers do not have to be online at the same time; the messaging infrastructure reliably stores messages until the receiving party is ready to receive them.

You are designing a Windows Azure application.
The application contains one web role and three worker roles.
You need to recommend an approach for updating only one role without interrupting the other roles.
What should you recommend? the whole thing and it works now, it seems for some reason CName entry was gone from GoDaddy (not sure if taking down the web service has got to do something with it).

You are planning an upgrade strategy for a Windows Azure application.
You need to identify changes that will require application downtime.
Which change will always require downtime?
