Answer: A
Explanation/Reference:
Explanation:
Public static void Main(string[] args) {
Create a trace listener for the event log.
EventLogTraceListener myTraceListener = new EventLogTraceListener("myEventLogSource");
Add the event log trace listener to the collection.
Trace.Listeners.Add(myTraceListener);
// Write output to the event log.
Trace.WriteLine("Test output");
}

You need to create a method that can be called by using a varying number of parameters.
What should you use?
A. Method overloading
B. Derived classes
C. Named parameters
D. Enumeration
Answer: A
Explanation/Reference:
Explanation:
Member overloading means creating two or more members on the same type that differ only in the number
or type of parameters but have the same name.
Overloading is one of the most important techniques for improving usability, productivity, and readability of
reusable libraries. Overloading on the number of parameters makes it possible to provide simpler versions
of constructors and methods. Overloading on the parameter type makes it possible to use the same
member name for members performing identical operations on a selected set of different types.

You are creating a class library that will be used in a web application.
You need to ensure that the class library assembly is strongly named.
What should you do?
A. Use the gacutil.exe command-line tool.
B. Use the xsd.exe command-line tool.
C. Use the aspnet_regiis.exe command-line tool.
D. Use assembly attributes.
Answer: D
Explanation/Reference:
Explanation:
The Windows Software Development Kit (SDK) provides several ways to sign an assembly with a strong
name:
Using the Assembly Linker (Al.exe) provided by the Windows SDK.

Using assembly attributes to insert the strong name information in your code. You can use either the

AssemblyKeyFileAttribute or the AssemblyKeyNameAttribute, depending on where the key file to be
used is located.
Using compiler options such /keyfile or /delaysign in C# and Visual Basic, or the /KEYFILE or /

DELAYSIGN linker option in C++. (For information on delay signing, see Delay Signing an Assembly.)
Note:
A strong name consists of the assembly's identity-its simple text name, version number, and culture
information (if provided)-plus a public key and a digital signature. It is generated from an assembly file
(the file that contains the assembly manifest, which in turn contains the names and hashes of all the files
that make up the assembly), using the corresponding private key. Microsoft® Visual Studio® .NET and
other development tools provided in the .NET Framework SDK can assign strong names to an assembly.
Assemblies with the same strong name are expected to be identical.

You write the following method (line numbers are included for reference only):

You need to ensure that the method extracts a list of URLs that match the following pattern:
@ http://(www\.)?([^\.]+)\.com;
Which code should you insert at line 07?

A. Option A
B. Option B

D. Option D
Answer: D
Explanation/Reference:
Explanation:
MatchCollection

Represents the set of successful matches found by iteratively applying a regular expression pattern to
the input string.
The collection is immutable (read-only) and has no public constructor. The Regex.Matches method
returns a MatchCollection object.
List<T>.Add Method

Adds an object to the end of the List<T>.

You are developing a game that allows players to collect from 0 through 1000 coins. You are creating a
method that will be used in the game. The method includes the following code. (Line numbers are included
for reference only.)
0 1 public string FormatCoins(string name, int coins)
0 2 {
0 3
0 4 }
The method must meet the following requirements:
Return a string that includes the player name and the number of coins.

Display the number of coins without leading zeros if the number is 1 or greater.
