Demo Questions
Question 1
You are developing an application that includes a class named Order. The application will store a collection of Order objects.
The collection must meet the following requirements:
- Use strongly typed members.
- Process Order objects in first-in-first-out order.
- Store values for each Order object.
- Use zero-based indices.
You need to use a collection type that meets the requirements.
Which collection type should you use?
- Queue<T>
- SortedList
- LinkedList<T>
- HashTable
- Array<T>
Correct answer: A
Explanation:
Queues are useful for storing messages in the order they were received for sequential processing. Objects stored in a Queue<T> are inserted at one end and removed from the other.

Question 2
You are developing an application. The application calls a method that returns an array of integers named employeeIds. You define an integer variable named employeeIdToRemove and assign a value to it. You declare an array named filteredEmployeeIds.
You have the following requirements:
- Remove duplicate integers from the employeeIds array.
- Sort the array in order from the highest value to the lowest value.
- Remove the integer value stored in the employeeIdToRemove variable from the employeeIds array.
You need to create a LINQ query to meet the requirements.
Which code segment should you use?
- Option A
- Option B
- Option C
- Option D
Correct answer: C
Question 3
You are developing an application that uses the Microsoft ADO.NET Entity Framework to retrieve order information from a Microsoft SQL Server database. The application includes the following code. (Line numbers are included for reference only.)
The application must meet the following requirements:
- Return only orders that have an OrderDate value other than null.
- Return only orders that were placed in the year specified in the OrderDate property or in a later year.
You need to ensure that the application meets the requirements.
Which code segment should you insert at line 08?
- Where order.OrderDate.Value != null && order.OrderDate.Value.Year >= year
- Where order.OrderDate.Value == null && order.OrderDate.Value.Year == year
- Where order.OrderDate.HasValue && order.OrderDate.Value.Year == year
- Where order.OrderDate.Value.Year == year
Correct answer: A
Explanation:
* For the requirement to use an OrderDate value other than null use:OrderDate.Value != null * For the requirement to use an OrderDate value for this year or a later year use:OrderDate.Value>= year * For the requirement to use an OrderDate value other than null use:
OrderDate.Value != null
* For the requirement to use an OrderDate value for this year or a later year use:
OrderDate.Value>= year
