Q14. - (Topic 5) 

You are developing a library to support multiple ASP.NET MVC web applications on a shared server. The library provides implementations of security algorithms. 

If a problem with any of the security algorithms is discovered, a new version of the library must be created and deployed. Application downtime during the update must be minimized. 

You need to ensure that the new version of the library will be used by all applications as soon as possible. 

What should you do? 

A. Build the web applications and include the security assembly as an embedded resource. 

When an update is needed, copy the new assembly to the bin directory for the application. 

B. Sign all assemblies in each application with the same key used to sign the security 


When an update is needed, create a new key pair and re-sign all assemblies. 

C. Build the security assembly as a netmodule in a shared location. 

Use the assembly linker to merge the netmodule into the assemblies for the application. 

When an update is needed, update the netmodule in the shared location. 

D. Install the security assembly in the Global Assembly Cache (GAC). 

When an update is needed, update the assembly in the GAC.

There are millions of entries in the table. Queries for historical flight information specify a set of airlines to search and whether the query should return only late flights. Results should be ordered by flight name. 

You need to specify which properties of the FlightInfo class should be used at the partition and row keys to ensure that query results are returned as quickly as possible. 

What should you do? (To answer, drag the appropriate properties to the correct location or locations in the answer area. Each property 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.) 


Q18. DRAG DROP - (Topic 3) 

You need to ensure that the transcode.exe utility is installed before the worker role starts.

Topic 4, Scenario 4 


You are developing a flight information consolidation service. The service retrieves flight information from a number of sources and combines them into a single data set. The consolidated flight information is stored in a SQL Server database. Customers can query and retrieve the data by using a REST API provided by the service. 

The service also offers access to historical flight information. The historical flight information can be filtered and queried in an ad hoc manner. 

The service runs on a Microsoft Azure Web Role. SSL is not used. 

Business Requirements 

. A new data source for historical flight information is being developed by a 

contractor located on another continent. 

. If a time zone is not specified, then it should be interpreted as Coordinated 

Universal Time (UTC). 

. When you upgrade a service from a staging deployment to a production 

deployment, the time that the service is unavailable must be minimized. 

. The default port must be used for HTTP. 

Technical Requirements 

The existing sources of flight information and the mechanism of exchange are listed below. 

. Blue Yonder Airlines provides flight information in an XML file. 

. Consolidated Messenger provides flight information in a Microsoft Access database that is uploaded every 12 hours to the service using SFTP. The company uses Port 22 for SFTP. 

. Margie's Travel provides and consumes flight information using serialized ADO.NET DataSets. Data is periodically synced between the service and Margie's Travel. 

. Trey Research provides data from multiple sources serialized in proprietary binary formats. The data must be read by using .NET assemblies provided by Trey Research. The assemblies use a common set of dependencies. 

. The current version of the Trey Research assemblies is All assemblies provided by Trey Research are signed with a key pair contained in a file named Trey.snk, which Trey Research also supplies. 

. The application specification requires that any third-party assemblies must have strong names.
