DRAG DROP
You need to identify the return types for the car year, price, brand and model. The solution must minimize the number of round trips between the clients and the web servers.
What should you identify? To answer, drag the appropriate return types to the correct objects. Each return type 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.
Select and Place:
Correct Answer:
Explanation/Reference:
Note: A round trip occurs when an object is deserialized and re-serialized in one operation.
From scenario: The application will provide users with the ability to search for a car by using advanced filtering options, such as the car brand, model, year, and price. All of this information will be stored as strings and will be displayed as drop-down lists.
The brand and model lists that will be displayed on the home page of the web application will be retrieved from Windows Communication Foundation (WCF) services hosted in the on-premises environment.
Target 1: Task<String>
Though Performance blocking and Sluggishness are the tailbacks for any application, we can easily overcome these bottlenecks by using asynchronous programming. But old-style practice for asynchronous programming is not way easy enou Target 2: Task<String>
Target 3: String
Target 4: String

I believe answer is correct:
1. Task.List.String
2. List.String
3. List.String
4. List.String
According to the case study (from https://www.briefmenow.org/microsoft/what-should-you-identify-314/) , all of them are lists:
The application will provide users with the ability to search for a car
by using advanced filtering options, such as the car brand, model, year, and price. All of this information will be
stored as strings and will be displayed as drop-down lists.
The brand and model lists that will be displayed on the home page of the web application will be retrieved from
Windows Communication Foundation (WCF) services hosted in the on-premises environment.
Further in the brand list should be async as stated in performance requirements.
Because of this I think the answer is:
– Task
– List
– List
– List
