HOTSPOT
A class named AccountViewModel includes a property named Name that will be bound to a control.
The Name property will occasionally be updated programmatically. The updated values must
be reflected in the bound control.
You need to implement the interface so that the AccountViewModel class can inform WinRT
when there is a new value to display.
You have the following code:

Which code snippets should you insert in Target 1 and Target 2 to complete the code? (To
answer, select the correct code snippet from each drop-down list in the answer area.)

DRAG DROP
You are developing a Windows Store app.
The app will use a model that is defined by using the following code:

You need to create a class to represent a collection of Customer objects. The class will be
used for data binding. The solution must ensure that if changes are made to the objects of
the class, a notification will be sent to the user interface (UI) controls to which the collection
is bound.
You have the following signature:
public classCustomerList : Target 1<Target 2>
Which elements should you include in Target 1 and Target 2 to complete the signature for
the collection class? (To answer, drag the appropriate elements to the correct targets. Each
element 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.)

DRAG DROP
You are planning the architecture of a new Windows Store style e-commerce app. You need
to maximize reusability by breaking app components into logical layers.
To which logical layers should you assign the components? (To answer, drag the
appropriate components to the correct layers in the answer area. Each component 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.)

You are developing a Windows Store app.
You need to create a certificate to sign the app in a test environment.
Which tool or tools should you use?
