Question 1 of 268

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?

    Correct Answer: A

    Queue<T> is the optimal collection type for meeting the listed requirements. It supports strongly typed members and ensures first-in-first-out (FIFO) processing, which is vital for order processing. Additionally, although Queue<T> does not natively support indexing, it meets the FIFO requirement efficiently. While the zero-based indices requirement seems contradictory, the primary requirement of FIFO processing takes precedence given the nature of order handling. Using Queue<T> allows for orderly and timely processing of Order objects as they are received.

Question 2 of 268

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?

    Correct Answer: C

    The requirements are to remove duplicate integers from the employeeIds array, sort the array in order from highest to lowest value, and remove the integer value stored in the employeeIdToRemove variable from the employeeIds array. Option C correctly uses the Distinct() method to remove duplicates, the Where() method to filter out the employeeIdToRemove, and OrderByDescending() to sort the array in descending order, followed by ToArray() to convert the result back to an array.

Question 3 of 268

You are developing an application that includes the following code segment. (Line numbers are included for reference only.)

The GetAnimals() method must meet the following requirements:

✑ Connect to a Microsoft SQL Server database.

✑ Create Animal objects and populate them with data from the database.

✑ Return a sequence of populated Animal objects.

You need to meet the requirements.

Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

    Correct Answer: B, D

    To meet the requirements of the GetAnimals method, two critical actions need to be performed: opening the connection to the Microsoft SQL Server database and correctly iterating through the results returned from the database query. Firstly, the sqlConnection.Open() method is necessary to establish a connection to the database. Without opening the connection, any attempt to execute a command on the database will fail. Secondly, using sqlDataReader.Read() is essential as it advances the SqlDataReader to the next record, allowing for each record to be read and processed in a loop. Thus, inserting the code segments sqlConnection.Open() at line 13 and while(sqlDataReader.Read()) at line 16 is the correct approach to ensuring the method meets its requirements.

Question 4 of 268

DRAG DROP -

You are developing a custom collection named LoanCollection for a class named Loan class.

You need to ensure that you can process each Loan object in the LoanCollection collection by using a foreach loop.

How should you complete the relevant code? (To answer, drag the appropriate code segments to the correct 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.)

Select and Place:

    Correct Answer:

Question 5 of 268

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?

    Correct Answer: A

    To ensure that the application returns only orders with a non-null OrderDate value and orders that were placed in the specified year or in any later year, the correct condition to use is 'Where order.OrderDate.Value != null && order.OrderDate.Value.Year >= year'. This condition first checks that the OrderDate has a value different from null, and then verifies that the order was placed in the specified year or later, satisfying both of the given requirements.
