Microsoft TS: Accessing Data with Microsoft .NET Framework 4 Sample Questions:

1. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application uses the ADO.NET Entity Framework to model entities.
The conceptual schema definition language (CSDL) file contains the following XML fragment.
<EntityType Name="Contact"> ... <Property Name="EmailPhoneComplexProperty"
Type="AdventureWorksModel.EmailPhone" Nullable="false" />
</EntityType>
...
<ComplexType Name="EmailPhone">
<Property Type="String" Name="EmailAddress" MaxLength="50" FixedLength="false" Unicode="true" />
<Property Type="String" Name="Phone" MaxLength="25" FixedLength="false" Unicode="true" /> </ComplexType>
You write the following code segment. (Line numbers are included for reference only.)
01 using (EntityConnection conn = new EntityConnection("name=AdvWksEntities"))
02 {
03 conn.Open();
04 string esqlQuery = @"SELECT VALUE contacts FROM
05 AdvWksEntities.Contacts AS contacts
06 WHERE contacts.ContactID == 3";
07 using (EntityCommand cmd = conn.CreateCommand())
08 {
09 cmd.CommandText = esqlQuery;
10 using (EntityDataReader rdr = cmd.ExecuteReader())
11 {
12 while (rdr.Read())
13
{
14
...
15
}
16
}
17
}
18 conn.Close(); 19 }
You need to ensure that the code returns a reference to a ComplexType entity in the model named
EmailPhone.
Which code segment should you insert at line 14?

A) int FldIdx = 0; EntityKey key = record.GetValue(FldIdx) as EntityKey; foreach (EntityKeyMember keyMember in key.EntityKeyValues)
{
return keyMember.Key + " : " + keyMember.Value;
}
B) int fieldCount = rdr["EmailPhone"].DataRecordInfo.FieldMetadata.Count; for (int FldIdx = 0; FldIdx < fieldCount; FldIdx++) {
rdr.GetName(FldIdx);
if (rdr.IsDBNull(FldIdx) == false)
{
return rdr["EmailPhone"].GetValue(FldIdx).ToString();
}
}
C) DbDataRecord nestedRecord = rdr["EmailPhoneComplexProperty"] as DbDataRecord; return nestedRecord;
D) IExtendedDataRecord record = rdr["EmailPhone"]as IExtendedDataRecord; int FldIdx = 0; return record.GetValue(FldIdx);

2. You use Microsoft Visual Studio 2010 and Microsoft. NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server database. You use Entity SQL of the ADO.NET Entity
Framework to retrieve data from the database.
You need to define a custom function in the conceptual model. You also need to ensure that the function
calculates a value based on properties of the object.
Which two XML element types should you use? (Each correct answer presents part of the solution. Choose
two.)

A) Dependent
B) DefiningExpression
C) Function
D) Association
E) FunctionImport

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application retreives data from Microsoft SQL Server 2008 database named AdventureWorks. The AdventureWorks.dbo.ProductDetails table contains a column names ProductImages that uses a varbinary(max) data type.
You write the following code segment. (Line numbers are included for reference only.)
01 SqlDataReader reader = command.ExecureReader(--empty phrase here --);
02 while(reader.Read())
03 {
04 pubID = reader.GetString(0);
05 stream = new FileStream(...);
06 writer = new BinaryWriter(stream);
07 startIndex = 0;
08 retval = reader.GetBytes(1, startIndex, outByte, 0, bufferSize);
09 while(retval == bufferSize)
10 {
11 ...
12 }
13 writer.Write(outbyte, 0, (int)retval-1);
14 writer.Flush();
15 writer.Close();
16 stream.Close();
17 }
You need to ensure that the code supports streaming data from the ProductImages column. Which code segment should you insert at the empty phrase in line 01?

A) CommandBehavior.SequentialAccess
B) CommandBehavior.Default
C) CommandBehavior.KeyInfo
D) CommandBehavior.SingleResult

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server database. The application uses the ADO.NET Entity
Framework to manage order data.
The application makes a Web service call to obtain orders from an order-tracking system.
You need to ensure that the orders are added to the local data store. Which method should you call on the
ObjectContext?

A) AttachTo
B) AddObject
C) ApplyCurrentValues
D) Attach

5. You use Microsoft .NET Framework 4.0 and the Entity Framework to develop an application.
You create an Entity Data Model that has an entity named Customer. You set the optimistic concurrency
option for Customer.
You load and modify an instance of Customer named loadedCustomer, which is attached to an
ObjectContext named context.
You need to ensure that if a concurrency conflict occurs during a save, the application will load up-to-date
values from
the database while preserving local changes. Which code segment should you use?

A) try {
context.SaveChanges();
}
catch(OptimisticConcurrencyException ex)
{
context.Refresh(RefreshMode.StoreWins, loadedCustomer);
}
B) try {
context.SaveChanges();
}
catch(EntitySqlException ex)
{
context.Refresh(RefreshMode.ClientWins, loadedCustomer);
}
C) try {
context.SaveChanges();
}
catch(OptimisticConcurrencyException ex)
{
context.Refresh(RefreshMode.ClientWins, loadedCustomer);
}
D) try {
context.SaveChanges();
}
catch(EntitySqlException ex)
{
context.Refresh(RefreshMode.StoreWins, loadedCustomer);
}
