Which type of authentication should you recommend?
You are designing a SharePoint 2010 application and a Web application. You need to
design a security model for the application that requires users to be authenticated through
the Windows Live ID service without using a custom provider. Which type of authentication
should you recommend?
Which connection string fragment should you use?

Background
You are updating an existing Microsoft .NET Framework 4 application that includes a data
layer built with ADO.NET Entity Framework 4. The application communicates with a
Microsoft SQL Server 2008 instance named INST01 on a server named SQL01. The
application stores data in a database named Contoso in the INST01 instance.
You need to update the existing technology and develop new functionality by using
Microsoft Visual Studio 2010.
Application and Database Storage
The application tracks bicycle parts as they pass through a factory. Parts are represented by
the abstract Part entity and its associated partial classes. Each part has a name stored in the
Name field and a unique identifier stored in the Id field.
Parts are either component s (represented by the Component class) such as chains, wheels,
and frames, or finished product s (represented by the Product class) such as completed
bicycles. The Component class and the Product class derive from the Part class and may
contain additional class-specific properties.
Parts may have a color (represented by the Color class), but not all parts have a color, Parts
may be composed of other parts, and those parts may in turn be composed of other parts ; any
p art represents a tree of the parts that are used to build it, The lowest level of the tree consists
of c omponents that do not contain other component s.
A p roduct is a p art that has been completed and is ready to leave the factory. A p roduct
typically consists of many c omponents (forming a tree of child p arts) but can also be
constructed by combining other p roducts and/or c omponents to form a bundled p roduct,
such as a bicycle and a helmet that are sold together.
C omponents and p roducts are stored in a database table named Parts by using a table-perhierarchy (TPH) mapping. Components have a null ProductType field and a non-null
PartType field. Products have a non-null ProductType field and a null PartType field.

DRAG DROP
The user interface requires that a paged view be displayed of all the products sorted in alphabetical
order. The user interface supplies a current starting index and a page size in variables named
startlndex and pageSize of type Integer. You need to construct a LINQ expression that will return the
appropriate Parts from the database from an existing ContosoEntities context object named context.
You begin by writing the following expression:
context.Paces
Which query parts should you use in sequence to complete the expression? (To answer, move the
appropriate actions from the list of actions to the answer area and arrange them in the correct
order.)

Your network contains a server named Server1. Server1 runs Windows Server 2008 R2 and has a

10.0.0.1. The default gateway has a metric value of 100. You configure a second default gateway
that uses an address of 10.0.0.2. You need to ensure that 10.0.0.2 is only used as the default
