What is the best practice for deploying custom code to a SharePoint farm

  1. as a web part

  2. solution package

  3. user control

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

Solution packages (.wsp files) are the best practice for deploying custom code to SharePoint farms as they provide versioning, reusability, and proper deployment/retention processes. Web parts and user controls are components that can be deployed within solution packages, but the package itself is the deployment mechanism. SharePoint Designer is for customization, not code deployment.

By default, widgets are tightly packed next to each other. If you want to increase the white space between widgets, you will want to use the following Widget property

  1. android:padding

  2. android:layout_gravity

  3. android:layout_weight

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

To increase white space between widgets in Android layouts, you would use margins (android:layout_margin or similar), not padding. Padding adds space inside a widget's boundaries, while margins add space outside. None of the listed options (padding, layout_gravity, layout_weight) are the correct property for adding space between widgets. Option A (padding) adds internal space. Option B (layout_gravity) controls positioning within the parent. Option C (layout_weight) controls how remaining space is distributed among widgets.

_____ is a container that provides scrolling for its contents

  1. ScrollView

  2. ListView

  3. Both, a & b above

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

ScrollView is a container layout that provides scrolling functionality for its child content, allowing users to view content that exceeds the visible screen area. Option B (ListView) is a specialized view for displaying scrollable lists of data, but it's not the general-purpose container the question asks about. Option C is incorrect because while ListView does scroll, ScrollView is the fundamental container class specifically designed to add scrolling to any content.

FrameLayout is designed to block out an area on the screen to display a single item, acting as a placeholder that can be filled dynamically. The distractors describe RelativeLayout (relative positioning), AbsoluteLayout (x/y coordinates), and LinearLayout (linear alignment of children), which are distinct layouts.

Android defines two similar gravity attributes: android:gravity and android:layout_gravity. The android:gravity is a setting used by the container, whereas android:layout_gravity is used by the View.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The explanation is REVERSED in the statement. android:gravity controls content positioning WITHIN a View (used by the View), while android:layout_gravity controls the View's position WITHIN its container (used by the container/Layout). The statement incorrectly swaps their usage. The claimed answer B (False) is correct.

By default, LinearLayout is _______.

  1. Left and top-aligned

  2. Only left aligned

  3. Only top aligned

  4. None of above
Reveal answer Fill a bubble to check yourself

By default, Android's LinearLayout is horizontally oriented and aligns its children starting from the top-left corner (Gravity.TOP | Gravity.START or left-aligned in standard LTR layouts). Distractors incorrectly claim it is only left-aligned or only top-aligned, whereas both horizontal and vertical alignment rules apply.

The android:layout_weight property indicates the proportion of the free space that should go to that widget. If you set it to be 1 for one widget and 2 for the other widget. How do you interpret this representation.

  1. Both Widgets will occupy the same free space.

  2. 2nd Widget will use twice the free space that 1st Widget takes

  3. 1st Widget will use twice the free space that 2nd Widget takes

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

layout_weight allocates REMAINING (free) space proportionally. If widget A has weight 1 and widget B has weight 2, the total weight is 3. Widget A gets 1/3 of free space, widget B gets 2/3 - so B gets twice what A gets. The claimed answer B is correct.

In addition to its primary attributes of action and data URI, intent can include additional attributes called extras. An extra can provide more information to the component that receives the intent. It is accessed using -

  1. Intent.getIntentExtras()

  2. Intent.getExtras()

  3. Bundle.getExtras()

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

In Android, the extras associated with an Intent are retrieved using the Intent.getExtras() method, which returns a Bundle containing the key-value pairs. There is no getIntentExtras() method on Intent, making Intent.getExtras() the correct choice.
