Q84. - (Topic 2)
You have the following code (line numbers are included for reference only):
You need to ensure that if an exception occurs, the exception will be logged. Which code should you insert at line 28?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
Explanation: * XmlWriterTraceListener
Directs tracing or debugging output as XML-encoded data to a TextWriter or to a Stream,
such as a FileStream.
* TraceListener.TraceEvent Method (TraceEventCache, String, TraceEventType, Int32) Writes trace and event information to the listener specific output.
Syntax:
[ComVisibleAttribute(false)]
public virtual void TraceEvent(
TraceEventCache eventCache,
string source,
TraceEventType eventType,
int id
)
Q85. HOTSPOT - (Topic 1)
You are developing an application that includes a Windows Communication Foundation (WCF) service. The service includes a custom TraceSource object named ts and a method named DoWork. The application must meet the following requirements:
. Collect trace information when the DoWork() method executes. . Group all traces for a single execution of the DoWork() method as an activity that can be viewed in the WCF Service Trace Viewer Tool.
You need to ensure that the application meets the requirements.
How should you complete the relevant code? (To answer, select the correct code segment from each drop-down list in the answer area.)

Q86. - (Topic 2)
You are developing an application that will be deployed to multiple computers. You set the assembly name.
You need to create a unique identity for the application assembly.
Which two assembly identity attributes should you include in the source code? (Each correct answer presents part of the solution. Choose two.)
A. AssemblyTitleAttribute
B. AssemblyCultureAttribute
C. AssemblyVersionAttribute
D. AssemblyKeyNameAttribute
E. AssemblyFileVersion
....
Answer: B,C
Explanation: The AssemblyName object contains information about an assembly, which you can use to bind to that assembly. An assembly's identity consists of the following:
Simple name
Version number
Cryptographic key pair
Supported culture
B: AssemblyCultureAttribute
Specifies which culture the assembly supports.
The attribute is used by compilers to distinguish between a main assembly and a satellite
assembly. A main assembly contains code and the neutral culture's resources. A satellite
assembly contains only resources for a particular culture, as in
[assembly:AssemblyCultureAttribute("de")]
C: AssemblyVersionAttribute
Specifies the version of the assembly being attributed.
The assembly version number is part of an assembly's identity and plays a key part in
binding to the assembly and in version policy.
Q87. - (Topic 1)
You have the following code (line numbers are included for reference only):
You need to identify the missing line of code at line 15. Which line of code should you identify?
A. using (fooSqlConn.BeginTransaction())
B. while (fooSqlReader.Read())
C. while (fooSqlReader.NextResult())
D. while (fooSqlReader.GetBoolean(0))
Answer: B
Q88. - (Topic 2)
An application is throwing unhandled NullReferenceException and FormatException errors. The stack trace shows that the exceptions occur in the GetWebResult() method.
The application includes the following code to parse XML data retrieved from a web service. (Line numbers are included for reference only.)
You need to handle the exceptions without interfering with the existing error-handling infrastructure.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Option A
B. Option B
C. Option C
D. Option D
Answer: A,C
Explanation: A: The TryParse method is like the Parse method, except the TryParse method does not throw an exception if the conversion fails. It eliminates the need to use exception handling to test for a FormatException in the event that s is invalid and cannot be successfully parsed.
C: UnhandledException event handler If the UnhandledException event is handled in the default application domain, it is raised there for any unhandled exception in any thread, no matter what application domain the thread started in. If the thread started in an application domain that has an event handler for UnhandledException, the event is raised in that application domain.
Q89. - (Topic 1)
You are developing an application that includes the following code segment. (Line numbers are included for reference only.)
The GetCustomers() method must meet the following requirements:
Connect to a Microsoft SQL Server database.
Populate Customer objects with data from the database.
Return an IEnumerable<Customer> collection that contains the populated
Customer objects.
You need to meet the requirements.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Insert the following code segment at line 17: while (sqlDataReader.GetValues())
B. Insert the following code segment at line 14: sqlConnection.Open();
C. Insert the following code segment at line 14: sqlConnection.BeginTransaction();
D. Insert the following code segment at line 17: while (sqlDataReader.Read())
E. Insert the following code segment at line 17: while (sqlDataReader.NextResult())
Answer: B,D
Explanation:
SqlConnection.Open - Opens a database connection with the property settings specified by the ConnectionString.
http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.open.aspx SqlDataReader.Read - Advances the SqlDataReader to the next record. http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldatareader.read.aspx
Q90. - (Topic 2)
You are developing an application that generates code. The application includes the following code segment. (Line numbers are included for reference only.)

Which two code segments can you insert at line 05 to achieve this goal? (Each correct answer presents a complete solution. Choose two.)
A. Option A
B. Option B
C. Option C
D. Option D
Answer: A,C
