Question #1 (Topic: Question Set 1)
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?

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 assembly. 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.
Answer: D
Question #2 (Topic: Question Set 1)

Question #3 (Topic: Question Set 1)
DRAG DROP
You are developing a WCF Data Services service in Visual Studio to display movie information from a SQL Server database that changes every 24 hours. The
service is defined in the following class.
The application contains the following Entity Framework model.
The service must only return data for movies that are currently in theaters.
You need to add a method to the MovieService class to filter the data.
How should you build the method? (To answer, drag the appropriate code segments to the correct location or locations in the answer area. 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.)
