An on-premise application includes an application tier and a business tier.
The tiers are currently hosted on separate servers.
Each server has 4 CPU cores and 6 GB of memory.
You have the following requirements:

– Ensure that the business tier can be updated without affecting the application tier.
– Use the minimum role instance size that meets or exceeds the current server specifications.

You need to recommend a topology for hosting the application in Windows Azure.
What should you recommend?

You are migrating a solution to Windows Azure.
The solution includes a web application and a business logic layer.
The web application runs on three dual-core servers.
The business logic layer runs on two quad-core servers.
The Windows Azure application must match or exceed the current hardware specifications.
You need to recommend role instance sizes that minimize cost.
What should you recommend?

You are designing an upgrade strategy for a Windows Azure application that includes one web role with one instance.
You have the following requirements:

– Test the application on the Windows Azure platform.
– Ensure that application upgrades can be rolled back.
– Ensure that upgrade and rollback processes do not cause downtime.

You need to recommend an approach for upgrading the application.
What should you recommend?

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?

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?

An application has been migrated to the Windows Azure platform.
The application references a native x86 DLL.
The DLL source code is not available.
The application displays an error when loading the DLL.
You need to recommend an approach for ensuring that the application can load the DLL.
What should you recommend?

You are planning the migration of an existing application to Windows Azure and SQL Azure.
The original application includes a Microsoft SQL Server 2008 database.
You need to recommend an approach for ensuring that the database migrates successfully to SQL Azure.
Which two actions should you recommend?
(Each correct answer presents part of the solution. Choose two.)

You are designing a Windows Azure application that will execute long-running business processes.
Applying a configuration change requires role instances to recycle.
You must not recycle until processing is finished.
You need to recommend an approach for applying configuration changes.
What should you recommend?

A Windows Azure application includes a single-threaded worker role that has multiple instances.
The worker role hosts a Windows Communication Foundation (WCF) service.
Each request to the WCF service takes several seconds to complete.
You need to recommend an approach for ensuring that worker role instances do not receive requests while processing.
What should you recommend?

You plan to host a Windows Communication Foundation (WCF) service in a Windows Azure worker role.
Custom code is necessary to initialize and configure the service endpoint.
You need to recommend the point at which the application should initialize the WCF service.
