Question 1 of 270

DRAG DROP -
You are validating user input by using JavaScript and regular expressions.
A group of predefined regular expressions will validate two input fields:
✑ An email address in a function named validateEmail (for example, firstname@contoso.com)
✑ A nine-digit number that allows optional hyphens after the second and fifth character in a function named validateSSN(for example, 555555555 or 555-55-
5555)
You need to use the correct expression to validate the input.
Which expression should you insert into each function? (To answer, drag the appropriate regular expression statement to the correct location. Each regular expression statement 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.)

Question 2 of 270

You are developing a customer web form that includes the following HTML.
<input id="txtValue" type="text" />
A customer must enter a valid age in the text box prior to submitting the form.
You need to add validation to the control.
Which code segment should you use?
Exam 70-480: Question 2 - Image 1

Option A

Option B

Option C

Option D

Correct Answer: D

To validate that the input is a valid age, you need to ensure that the value entered into the input field is captured and checked against a regular expression that handles numbers. Option D uses the .val() method to get the value from the input field, which is the proper method for input elements. It then uses a regular expression (regex) to validate that the input is a numeric value, which matches the requirement of validating an age. Despite the presence of the leftover emailPattern.test(userinput) line, it correctly performs the necessary validation to check if the field is not empty and contains a valid numeric value.

Question 3 of 270

You are developing a customer contact form that will be displayed on a page of a company's website. The page collects information about the customer.
If a customer enters a value before submitting the form, it must be a valid email address.
You need to ensure that the data validation requirement is met.
What should you use?

Correct Answer: D

Question 4 of 270

DRAG DROP -
You are developing a form that captures a user's email address by using HTML5 and jQuery.
The form must capture the email address and return it as a query string parameter. The query string parameter must display the @ symbol that is used in the email address.
You need to implement this functionality.
How should you develop the form? (To answer, drag the appropriate code segment to the correct target or targets 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.)

Exam 70-480: Question 4 - Image 1

Correct Answer:

* The serialize() method creates a URL encoded text string by serializing form values.
You can select one or more form elements (like input and/or text area), or the form element itself.
The serialized values can be used in the URL query string when making an AJAX request.
Example: $("form").serialize());
* decodeURIComponent
The decodeURIComponent() function decodes a URI component.
Return Value: A String, representing the decoded URI
Incorrect Answers:
Not decodeURI:
decodeURI is intended for use on the full URI.
decodeURIComponent is intended to be used on .. well .. URI components that is any part that lies between separators (; / ? : @ & = + $ , #).

The application interacts with the service by using the following code. (Line numbers are included for reference only.)
Exam 70-480: Question 5 - Image 1

You need to authenticate to the WCF service.
What should you do?

At line 11, add the following lines of code. ,username: yourusername ,password: yourpassword

At line 11, add the following line of code. ,credentials: prompt

At line 06, replace the code with the following line of code. url: "http://contoso.com/Service.svc/GetCountry? Username=username&password=password",

At line 11, add the following line of code. The username and password will be stored in an XML file.

Correct Answer: A

To authenticate to the WCF service using jQuery's ajax method, the correct way is to add authentication credentials in the settings object. This can be done by specifying the 'username' and 'password' options within the $.ajax call. This approach directly passes the credentials required for HTTP access authentication. Therefore, adding 'username' and 'password' at line 11 is the correct method for authentication in this scenario.
