You are creating an ASP.NET Web application.
The application must call a WCF service by using a WCF routing service.
You need to ensure that the application can invoke the target service by using the router endpoint.
What should you do?

• A. Add a service reference to the target service. In the client binding configuration, specify the address of the router service.
• B. Add a service reference to the router service. In the client binding configuration, specify the address of the router service.
• C. Add a service reference to the router service. In the client binding configuration, specify the address of the target service.
• D. Add a service reference to the target service. In the client binding configuration, specify the address of the target service.

You are creating an ASP.NET Web application that uses the SqlMembershipProvider.
You plan to test locally and deploy to multiple production servers.
You need to ensure that each deployed application accesses the same production database in Microsoft
SQL Server.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Modify the connection string in the web.config file to specify the names of the production server and
  database.
• B. Right-click App_Data in your Visual Studio 2010 project, click Add, and select New Item to create the SQL Server database on the appropriate SQL Server computer.
• C. Modify the web.release.config file to transform the connection string to specify the names of the production server and database.
• D. Run the aspnet_regsql command to create the database on the appropriate SQL Server computer.

You are implementing an ASP.NET page.
Client-side script requires data.
Your application includes a class named Person with a Name property of type string.
The code-behind file of the page includes the following code segment.
public string JsonValue;
List<Person> people = GetPeopleList();
JavaScriptSerializer json = new JavaScriptSerializer();
You need to use the JavaScriptSerializer class to serialize only the Name property of each item in the
people list.
Which code segment should you use?

• A. var names = from person in people
  select person;
  JsonValue = "{" + json.Serialize(names) + "}";
• B. JsonValue = json.Serialize(people.Select(p => p.Name));
• C. JsonValue = json.Serialize(people.SelectMany( p =>Name.AsEnumerable()));
• D. var names = from person in people
  select person;
  JsonValue = json.Serialize(names);

You are implementing an ASP.NET application. You add the following code segment.
public List<Person> GetNonSecretUsers()
{ string[] secretUsers = {"@secretUser", "@admin", "@root"}; List<Person> allpeople = GetAllPeople(); ...
}
You need to add code to return a list of all Person objects except those with a UserId that is contained in the secretUsers list.
The resulting list must not contain duplicates. Which code segment should you use?

• A. return from p in allPeople from u in secretUsers where p.UserId != u select p;
• B. var secretPeople = (from p in allPeople from u in secretUsers where p.UserId == u select p).Distinct();
  return allPeople.Except(secretPeople);
• C. List<Person> people = new List<Person>( from p in allPeople from u in secretUsers where p.UserId != u select p);
  return people.Distinct();
• D. return (from p in allPeople from u in secretUsers where p.UserId != u select p).Distinct();
