You are adding a public method named UpdateScore to a public class named ScoreCard.
The code region that updates the score field must meet the following requirements:
It must be accessed by only one thread at a time.
It must not be vulnerable to a deadlock situation.
You need to implement the UpdateScore() method.
What should you do?

DRAG DROP
You are developing an application that will include a method named GetDat
a The GetData() method will retrieve several lines of data from a web service by using a
System.IO.StreamReader object.
You have the following requirements:
The GetData() method must return a string value that contains the first line of the response from the
web service.
The application must remain responsive while the GetData() method runs.
You need to implement the GetData() method.
How should you complete the relevant code? (To answer, drag the appropriate objects to the
correct locations in the answer area. Each object 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 developing an application that includes a class named Kiosk. The Kiosk class includes a static
property named Catalog. The Kiosk class is defined by the following code segment. (Line numbers
are included for reference only.)

You have the following requirements:
Initialize the _catalog field to a Catalog instance.
Initialize the _catalog field only once.
Ensure that the application code acquires a lock only when the _catalog object must be instantiated.
You need to meet the requirements.
Which three code segments should you insert in sequence at line 09? (To answer, move the
appropriate code segments from the list of code segments to the answer area and arrange them in
the correct order.)

DRAG DROP
You develop an application that displays information from log files when errors occur. The
application will prompt the user to create an error report that sends details about the error and the
session to the administrator.
When a user opens a log file by using the application, the application throws an exception and
closes.
The application must preserve the original stack trace information when an exception occurs during
this process.
You need to implement the method that reads the log files.
How should you complete the relevant code? (To answer, drag the appropriate code segments to
the correct locations in the answer are
a Each code segment 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 C# application that has a requirement to validate some string input data by
using the Regex class.
The application includes a method named ContainsHyperlink. The ContainsHyperlink() method will
verify the presence of a URI and surrounding markup.
The following code segment defines the ContainsHyperlink() method. (Line numbers are included for
reference only.)

The expression patterns used for each validation function are constant.
You need to ensure that the expression syntax is evaluated only once when the Regex object is
initially instantiated.
Which code segment should you insert at line 04?

DRAG DROP
You are developing an application that implements a set of custom exception types. You declare the
custom exception types by using the following code segments:

The application includes a function named DoWork that throws .NET Framework exceptions and
custom exceptions.
The application contains only the following logging methods:

The application must meet the following requirements:
When AdventureWorksValidationException exceptions are caught, log the information by using the
static void Log (AdventureWorksValidationException ex) method.
When AdventureWorksDbException or other AdventureWorksException exceptions are caught, log
the information by using the static void I oq( AdventureWorksException ex) method.
You need to meet the requirements.
How should you complete the relevant code? (To answer, drag the appropriate code segments to
the correct locations in the answer are
a Each code segment 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 an application by using C#.
You have the following requirements:
Support 32-bit and 64-bit system configurations.
Include pre-processor directives that are specific to the system configuration.
Deploy an application version that includes both system configurations to testers.
Ensure that stack traces include accurate line numbers.
You need to configure the project to avoid changing individual configuration settings every time you
deploy the application to testers.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose
two.)

You are developing a method named CreateCounters that will create performance counters for an
application.
The method includes the following code. (Line numbers are included for reference only.)

You need to ensure that Counter1 is available for use in Windows Performance Monitor (PerfMon).
Which code segment should you insert at line 16?

You are developing an application that will transmit large amounts of data between a client
computer and a server.
You need to ensure the validity of the data by using a cryptographic hashing algorithm.
Which algorithm should you use?

You are developing an assembly that will be used by multiple applications.
You need to install the assembly in the Global Assembly Cache (GAC).
Which two actions can you perform to achieve this goal? (Each correct answer presents a complete
solution. Choose two.)
