Microsoft PRO: Designing and Developing Windows Azure Applications Sample Questions:

1. An on-premise application is exposed to external users through a Windows Communication Framework
(WCF) service endpoint registered in the Windows Azure AppFabric Service Bus.
You need to recommend an approach for providing transport-level security that maximizes performance
and minimizes bandwidth requirements.
What should you recommend?

A) Use Message Transmission Optimization Mechanism (MTOM) message encoding. Use HTTPS for message delivery.
B) Use reliable messaging. Use HTTP for message delivery.
C) Use binary message encoding. Use TCP for message delivery.
D) Use Plain Old XML (POX) messages. Use TCP for message delivery.

2. You are designing a Windows Azure application that will be subjected to significant loads.
The application resource utilization will be monitored remotely by using a predefined set of performance
counters.
You have the following requirements:
-Allow for continual monitoring of the performance counters.
-Allow for remote configuration of the performance counters. -Minimize Windows Azure Storage transactions.
You need to recommend an approach for remotely monitoring the application. What should you recommend?

A) Use Windows Azure Diagnostics to configure performance counters and perform scheduled transfers of the event logs.
B) In the deployed application, create the necessary PerformanceCounter objects and schedule transfers of the counter buffers.
C) In the deployed application, create the necessary PerformanceCounter objects and schedule transfers of the event logs.
D) Use Windows Azure Diagnostics to configure performance counters and perform scheduled transfers of the counter buffers.

3. You are designing a Windows Azure application.
The application will use a Windows Azure AppFabric Service Bus message buffer.
You need to recommend an approach for ensuring that only authorized users can discover and use the
message buffer.
What should you recommend?

A) Make the message buffer publicly discoverable. Include a Simple Web Token (SWT) in each message.
B) Make the message buffer discoverable to listeners and require authorization.
C) Make the message buffer discoverable to managers. Include a Simple Web Token (SWT) in each message.
D) Make the message buffer discoverable to managers and do not require authorization.

4. You are planning the migration of an existing application to Windows Azure and SQL Azure.
The current application includes reports that are hosted by SQL Server Reporting Services.
You need to recommend an approach for migrating the reports. What should you recommend?

A) Use Windows Azure to host client report definitions in an ASP.NET webpage.
B) Use SQL Azure to host client report definitions.
C) Use Windows Azure to host server report definitions in an ASP.NET webpage.
D) Use SQL Azure to host server report definitions.

5. Multiple Windows Azure applications connect to multiple SQL Azure servers.
On-premise users connect to the SQL Azure servers for a variety of purposes.
You successfully deploy a new Windows Azure application with its own SQL Azure server.
When on- premise users attempt to connect to the new SQL Azure server they receive connection
errors.
You need to recommend an approach for mitigating the connectivity issue.
What should you recommend?

A) Open port 1433 on the network firewall.
B) Change the firewall rules of the new SQL Azure server to allow access by computers on the internal network.
C) Use Security Support Provider Interface (SSPI).
D) Disable the validation of the SSL certificate for the SQL Azure server through the connection string.
