70-516 Online Practice Questions and Answers
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to a Microsoft SQL Server 2008 database. The application contains two SqlCommand objects named cmd1 and cmd2.
You need to measure the time required to execute each command.
Which code segment should you use?
A. Dim w1 As New Stopwatch()w1.Start()cmd1.ExecuteNonQuery()w1.[Stop] ()Trace.WriteLine(w1.ElapsedMilliseconds)w1.Start()cmd2.ExecuteNonQuery()w1. [Stop] ()Trace.WriteLine(w1.ElapsedMilliseconds)
B. Dim w1 As New Stopwatch()w1.Start()cmd1.ExecuteNonQuery()w1.[Stop] ()Trace.WriteLine(w1.ElapsedMilliseconds)w1.Reset()cmd2.ExecuteNonQuery() w1. [Stop] ()Trace.WriteLine(w1.ElapsedMilliseconds)
C. Dim w1 As Stopwatch = Stopwatch.StartNew()cmd1.ExecuteNonQuery()w1.[Stop] ()Trace.WriteLine(w1.ElapsedMilliseconds)w1.Start() cmd2.ExecuteNonQuery() w1.[Stop]() Trace.WriteLine(w1.ElapsedMilliseconds)
D. Dim w1 As Stopwatch = Stopwatch.StartNew()cmd1.ExecuteNonQuery() w1.[Stop]() Trace.WriteLine(w1.ElapsedMilliseconds) w1 = Stopwatch.StartNew() cmd2.ExecuteNonQuery() w1. [Stop]() Trace.WriteLine(w1.ElapsedMilliseconds)
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 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">
...
Type="AdventureWorksModel.EmailPhone" Nullable="false" /> ... MaxLength="50" FixedLength="false" Unicode="true" /> FixedLength="false" Unicode="true" /> 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 { 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. IExtendedDataRecord record = rdr["EmailPhone"]as IExtendedDataRecord; int FldIdx = 0; return record.GetValue(FldIdx); C. DbDataRecord nestedRecord = rdr["EmailPhoneComplexProperty"] as DbDataRecord; return nestedRecord; D. 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();}}
You use Microsoft .NET Framework 4 to create a data access layer component.
The component accesses data from a Microsoft SQL Server database named DB1. The component contains a class named Classl that represents data from a table in DB1 named Tablel. The following is the definition of Classl:
A database developer creates the following stored procedure to add entries to Table1:
You need to edit the Entity Data Model (EDM) for EDMCIassl to use the uspInsertTablel stored procedure to add data to the database.
What should you do? (Develop the solution by selecting and ordering the required code snippets. You may not need all of the code snippets.)
