Which three actions should you perform in sequence?
DRAG DROP
You are developing an application by using C#. The application will process several objects
per second.
You need to create a performance counter to analyze the object processing.
Which three actions should you perform in sequence? (To answer, move the appropriate
actions from the list of actions to the answer area and arrange them in the correct order.)
Which code segment should you use?
You are developing a Windows Store app by using JavaScript.
You need to ensure that the user can capture video with the built-in camera and then
process the resulting file.
Which code segment should you use?
For each of the following statements, select Yes if the statement is true…
HOTSPOT
You have a Windows Store app. You are reviewing code that caches data.
The code includes the following segment. Line numbers are included for reference only.
<code>
01 function setLocaiStorage(value) {
02 var storage = window.localStorage;
03 var value = document.getElement3yId(‘textToAdd’).text;
04 storage.name = ‘John’;
05 storage.phone = ‘ 555-555-0100’;
06 storage.message = value;
07 }
</code>
For each of the following statements, select Yes if the statement is true. Otherwise, select
No. Each correct selection is worth one point.
Which code segment should you use?
You are developing a Windows Store app by using JavaScript. The app will use an
accelerometer to detect user movements that affect the host device. (In the code segments,
accelerometer is an instance of the sensor that is connected to the host device.)
The app must report user movement either once every five seconds or at the device’s most
frequent polling interval available, whichever is less frequent.
You need to configure the accelerometer to meet the requirements.
Which code segment should you use?
Which code segment should you use?
You are developing a C# application that includes a class named Product. The following
code segment defines the Product class:
You implement System.ComponentModel.DataAnnotations.IValidateableObject interface to
provide a way to validate the Product object.
The Product object has the following requirements:
The Id property must have a value greater than zero.
The Name property must have a value other than empty or null.
You need to validate the Product object. Which code segment should you use?
How should you complete the relevant code?
HOTSPOT
You are developing a Windows Store app by using JavaScript. The app will use the device’s
light sensor.
You need to access the light sensor and register events to handle its output.
How should you complete the relevant code? (To answer, select the appropriate code
segment from the drop-down list in the answer area.)
which form should you implement the score member?
You are creating a class named Game.
The Game class must meet the following requirements:
Include a member that represents the score for a Game instance.
Allow external code to assign a value to the score member.
Restrict the range of values that can be assigned to the score member.
You need to implement the score member to meet the requirements.
In which form should you implement the score member?
You need to create a method that returns a list of valid customer IDs
DRAG DROP
You have a method named GetCustomerIDs that returns a list of integers. Each entry in the
list represents a customer ID that is retrieved from a list named Customers. The Customers
list contains 1,000 rows.
Another developer creates a method named ValidateCustomer that accepts an integer
parameter and returns a Boolean value. ValidateCustomer returns true if the integer
provided references a valid customer. ValidateCustomer can take up to one second to run.
You need to create a method that returns a list of valid customer IDs. The code must
execute in the shortest amount of time.
What should you do? (Develop the solution by selecting and ordering the required code
snippets. You may not need all of the code snippets.)
For each of the following statements, select Yes if the statement is true…
HOTSPOT
You have the following code:
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
complete each statement according to the information presented in the code.
