You need to maintain data integrity including retrieving identical sets across reads in all situations that use
transactions.
Which isolation level should you use?

• A.Serializable
• B.Repeatable
• C.ReadCommitted
• D.ReadUncommitted

You are creating a WCF service.
The service endpoints must be exposed to the Windows Azure Service Bus. The service bus has a namespace
named RestaurantSB. The key provider is "owner".
You need to modify the web.config file to expose the endpoints.
How should you modify the file? (To answer, drag the appropriate attributes to the correct location or
locations in the answer area. Each attribute 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.)

Correct Answer:

Explanation

The GetVendors() action in the ProcessedOrderController controller is querying the database each time it is
run. The GetVendors() action must query the database only if the cache is null.
You need to add code to the action at line PC33 to cache the data.
Which code segment can you use? (Each correct answer presents a complete solution. Choose all that apply.)

• A.cache.Set(new CacheItem("vendorKey", vendors), GetVendorPolicy());
• B.cache.Add(new CacheItem("vendorKey", vendors) , GetVendorPolicy());
• C.cache.AddOrGetExisting("vendorKey", context, new CacheItemPolicy());
• D.cache.Add("vendors", vendors, new CacheItemPolicy());

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.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.
• B.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.
• C.Install the security assembly in the Global Assembly Cache (GAC).
  When an update is needed, update the assembly in the GAC.
• D.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.

You are developing a Windows Communication Foundation (WCF) service for a company. The service will
be used for bidirectional communications between the company's physical offices.
You plan to implement Azure Service Bus.
You need to configure the WCF service.
Which type of binding should you use?

• A.BasicHttpBinding
• B.NetTcpRelayBinding
• C.NetTcpBinding
