QUESTION 2
You want to send the HTTP request with the help of a Button component. Which of the following syntaxes should you use used?
A. <mx: Button label = “Request” click = “service.sendo”>
B. <mx: Button label = “Request” click = service.sendo>
C. <mx: Button label = “Request” service.sendo>
D. <mx: Button label = “Request, service.sendo>
Answer: A
Explanation:
A user can send an HTTP request using the HTTPRequest objects send( ) method. For example, if a user wants to retrieve data when the application starts, he can call the send( ) method in the applications creationComplete event handler:
<mx :Application xmlns:mx=http://www.adobe.com/2006/mxml” creationComplete = “httpservice.sendQ’>
</mx :Application >
On the other hand, the user can also send the request upon a user event, such as to send data on a mouse click using the event handler of the Button component:
<mx :Button label=Request” click=”service.sendQ/>
Answer options C, B, and D are incorrect. <mx: Button label = “Request” service.sendo>, <mx:
Button label = “Request” click = service.sendo>, and <mx: Button label = “Request, service.send( ) > are invalid syntaxes to send the HTTP request with the help of a Button component.
QUESTION 3
Which of the following styles are used in the <mx:Label> MXML tag? Each correct answer represents a complete solution. Choose all that apply.
A. fontSize
B. fontGridFitType
C. fontAntiAliasType
D. font-family
Answer: ABC
Explanation:
fontSize , fontAntiAliasType, and fontGridFitType styles are used in the <mx:Label> MXML tag. In the Label control, the fontSize style is used to set the height of the text in pixels; by default it is 10 for all controls. The fontAntiAliasType style is used to apply anti aliasing to all the text in a TextField subcontrol. The default value is “advanced, which enables advanced anti-aliasing for the font. When it is set to normal, the advanced antialiasing is disabled. The fontGridFitType style can be only applied when a user is using an embedded font and the fontAntiAliasType property is set to “advanced. Answer option D is incorrect. The font-family style is not a valid style type of the Label control.
QUESTION 4
Which class is used to handle and dispatch event objects to ActionScript event handler functions?
A. AsyncToken
B. ItemResponder
C. UlComponent
D. ResultEvent
Answer: B
Explanation:
The ItemResponder class handles and dispatches event objects to ActionScript event handler functions and can be used instead of attribute-based event listeners or the add EventListener( ) method. For using ItemResponder, a user first creates custom event handler functions to handle an RPC request’s result and fault events. In addition to the expected event object, each event handler function receives an AsyncToken argument. Answer options A, D, and C are incorrect. AsyncToken, ResultEvent, and UlComponent are not valid classes to handle and dispatch event objects to ActionScript event handler functions.

QUESTION 10
Which of the following MXML syntaxes creates an HTTPService object?
A. <mx;HTTPService id = “webService” url = “contacts.xml’/>
B. <mx;HTTPService url = “contacts.xml”/>
C. <mx;HTTPService id = “webService” & url=”contacts.xml”/>
D. <mx;HTTPService id = “webService”>
Answer: A

The url property shows the URL and can be set with either a literal String, or with a binding expression. On the other hand, a user can also declare the object first and then set its url in a separate statement:
private var webService:HTTPService = new HTTPServiceQ; myService.url = “data/contacts.xml’;
Answer options D, B, and C are incorrect. <mx ;HTTPService id=”webService”>, <mx ;HTTPService url = “contacts.xml”/>, and <mx; HTTPService id=”webService” & url =”contacts.xml”/> are not valid syntaxes to create an HTTPService object.
