Choose the correct Order of life cycle of page loading in zk

  1. Page initial , Event processing , Component Creation , Rendering

  2. Page initial , Rendering , Component Creation , Event processing

  3. Page initial , Component Creation , Event processing , Rendering

  4. Page initial , Component Creation , Rendering , Event processing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The ZK page lifecycle follows: (1) Page Initial - initialization and parameter retrieval, (2) Component Creation - creating component tree from ZUML or programmatic creation, (3) Event Processing - processing queued events, (4) Rendering - generating output for the browser. This sequence ensures components exist before events are processed, and events complete before final rendering. Option C correctly shows this order.

Funtion Redraw() is called at which stage of in life cycle of page loading in zk ?

  1. Page initial

  2. Component Creation

  3. Event processing

  4. Rendering
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The redraw() method in ZK is called during the Rendering phase of the page lifecycle. After event processing has modified component states, redraw() regenerates the HTML output for affected components. It is not called during Page Initial, Component Creation, or Event Processing phases - only when the modified component tree needs to be rendered to the client.

Which one is not a calendar event?

  1. Creation Event

  2. FirstUpdateEvent

  3. DoubleClickEvent

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In event naming conventions, FirstUpdateEvent is not a standard calendar event type. Standard calendar events typically include Creation, Update, Delete, and click-related events. FirstUpdateEvent is likely a distractor as it's not commonly used.

  1. Namespace

  2. Assembly

  3. Class

  4. Interface
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An assembly is the smallest unit of deployment in .NET. Assemblies contain compiled code (IL), metadata, and resources, and are deployed as DLL or EXE files. Namespaces, classes, and interfaces are logical organization within assemblies but cannot be deployed independently.

Select the events available for a gridview/datagrid

  1. RowDataBound

  2. ItemDataBound

  3. RowClick

  4. ItemClick
Reveal answer Fill a bubble to check yourself
A,B Correct answer
Explanation

RowDataBound is a GridView event that fires when each row is data-bound, allowing customization of row appearance or content. ItemDataBound is the equivalent event for the older DataGrid control. Both are valid events for their respective controls, though GridView is the modern ASP.NET control.

What does the .NET PermView.exe utility do?

  1. It is used to view the minimal, optional, and refused permission sets requested by an assembly.

  2. It establishes a permanent view of the managed heap

  3. It provides an interface to the persistable dynamic assemblies stored on disk.

  4. It sets the permissions on a Dataset view object

  5. It persists the view of a Dataset by serializing the view to an XML stream
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

PermView.exe is a .NET SDK utility that displays the permission requests (minimal, optional, refused) declared in an assembly's metadata. Options B through E describe unrelated functionality - PermView has nothing to do with Dataset views, heap management, or dynamic assemblies. It's specifically a security diagnostic tool for examining CAS (Code Access Security) permission requests.

When inserting an Ouput Value in your script, which DataTable Sheet can you choose to output to?

  1. Local Action Sheet

  2. Global or Local Action Sheet

  3. Global Action sheet

  4. None of the Above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When inserting output values in QTP/UFT, you can direct the output to either the Global DataTable sheet (accessible across all actions) or a Local Action DataTable sheet (specific to that action). This flexibility allows you to choose the appropriate scope for your captured values. Option B correctly identifies that both options are available.

Which source snippet connect the TextView object (e.g. “tv”) with on-screen display -

  1. tv.setText(“Quiz II”)

  2. setContentView(tv)

  3. c. TextView tv = new TextView (this)

  4. setContentView()

  5. None of above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In Android Activity, setContentView() connects a View or layout resource to the screen. After creating a TextView tv, calling setContentView(tv) makes it the root View displayed. setText() only changes content, and TextView tv = new TextView(this) creates the object but doesn't display it.

A test frame stores which of the following?

  1. A list of all objects on the home page, such as HtmlImage, HtmlText, HtmlLinks, etc

  2. Testcases to execute.

  3. Commentary information

  4. An object of class BrowserChild window that holds application home page.
Reveal answer Fill a bubble to check yourself
A,C,D Correct answer
Explanation

A test frame in SilkTest stores application state information including: all objects on the home page (HtmlImage, HtmlText, HtmlLinks), commentary information for documentation, and the BrowserChild window object that holds the application home page. Test cases themselves are stored in test plan files, not in the test frame.

Is it possible to add object in ViewState in .NET?

  1. Not Possible

  2. Always Possible

  3. Only If object have Serializable feature or have TypeConverter option

  4. Only if object is an String
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

ViewState in ASP.NET can store objects, but the object must be serializable. Objects marked with the [Serializable] attribute or those with a TypeConverter can be stored in ViewState. Non-serializable objects cannot be persisted because ViewState needs to convert objects to a string format for transport.
