QUESTION 4
You need to write a console application that meets the following requirements:
If the application is compiled in Debug mode, the console output must display Entering debug mode.
If the application is compiled in Release mode, the console output must display Entering release mode.
Which code should you use?lead4pass 70-483 exam question q4

A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: B
Explanation: When the C# compiler encounters an #if directive, followed eventually by an #endif directive, it will compile
the code between the directives only if the specified symbol is defined. Unlike C and C++, you cannot assign a numeric
value to a symbol; the #if statement in C# is Boolean and only tests whether the symbol has been defined or not. For
example, #define DEBUG // … #if DEBUG Console.WriteLine(“Debug version”); #endif

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.)

lead4pass 70-483 exam question q11-1

A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: AC
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.

 

QUESTION 12
You are creating a console application named App1.
App1 retrieves data from the Internet by using JavaScript Object Notation (JSON).
You are developing the following code segment (line numbers are included for reference only):lead4pass 70-483 exam question q12

You need to ensure that the code validates the JSON string. Which code should you insert at line 03?

lead4pass 70-483 exam question q12-1

A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: D
Explanation: The JavaScriptSerializer Class Provides serialization and deserialization functionality for AJAX-enabled
applications.
The JavaScriptSerializer class is used internally by the asynchronous communication layer to serialize and deserialize
the data that is passed between the browser and the Web server. You cannot access that instance of the serializer.
However, this class exposes a public API. Therefore, you can use the class when you want to work with JavaScript
Object Notation (JSON) in managed code.


QUESTION 13
You need to write a method that retrieves data from a Microsoft Access 2013 database.
The method must meet the following requirements:
Be read-only.
Be able to use the data before the entire data set is retrieved. Minimize the amount of system overhead and the amount
of memory usage.
Which type of object should you use in the method?
A. SqlDataAdapter
B. DataContext
C. DbDataAdapter
D. OleDbDataReader
Correct Answer: D
Explanation: OleDbDataReader Class
Provides a way of reading a forward-only stream of data rows from a data source.
Example:
OleDbConnection cn = new OleDbConnection();
OleDbCommand cmd = new OleDbCommand();
DataTable schemaTable;
OleDbDataReader myReader;
//Open a connection to the SQL Server Northwind database. cn.ConnectionString = “Provider=SQLOLEDB;Data
Source=server;User ID=login; Password=password;Initial Catalog=Northwind”;
