Important Questions about asp.net
 

Q2: You create an application to send a message by e-mail. An SMTP
server is available on the local subnet. The SMTP server is named
smtp.Company.com. To test the application, you use a source address,
me@Company.com, and a target address, you@Company.com.
You need to transmit the e-mail message. Which code segment should you
use?

A. MailAddress addrFrom = new MailAddress("me@Company.com", "Me");
MailAddress addrTo = new MailAddress("you@Company.com", "You");
MailMessage message = new MailMessage(addrFrom, addrTo);
message.Subject = "Greetings!";
message.Body = "Test";

message.Dispose();

B. string strSmtpClient = "mstp.Company.com";
string strFrom = "me@Company.com";
string strTo = "you@Company.com";
string strSubject = "Greetings!";
string strBody = "Test";
MailMessage msg = new MailMessage(strFrom, strTo, strSubject, strSmtpClient);

C. MailAddress addrFrom = new MailAddress("me@Company.com");
MailAddress addrTo = new MailAddress("you@Company.com");
MailMessage message = new MailMessage(addrFrom, addrTo);
message.Subject = "Greetings!";
message.Body = "Test";
SmtpClient client = new SmtpClient("smtp.Company.com");

client.Send(message);

D. MailAddress addrFrom = new MailAddress("me@Company.com", "Me");
MailAddress addrTo = new MailAddress("you@Company.com", "You");
MailMessage message = new MailMessage(addrFrom, addrTo);
message.Subject = "Greetings!";
message.Body = "Test";
SocketInformation info = new SocketInformation();
Socket client = new Socket(info);

System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
byte[] msgBytes = enc.GetBytes(message.ToString());
client.Send(msgBytes);


Answer: C

Q3: You need to write a code segment that will create a common
language runtime (CLR) unit of isolation within an application. Which code
segment should you use?

A. AppDomainSetup mySetup = AppDomain.CurrentDomain.SetupInformation;
mySetup.ShadowCopyFiles = "true";


B. System.Diagnostics.Process myProcess;
myProcess = new System.Diagnostics.Process();


C. AppDomain domain;
domain = AppDomain.CreateDomain("CompanyDomain"):


D. System.ComponentModel.Component myComponent;
myComponent = new System.ComponentModel.Component();



Answer: C


Q4: You are developing an application that dynamically loads assemblies
from an application directory.
You need to write a code segment that loads an assembly named
Company1.dll into the current application domain. Which code segment
should you use?

A. AppDomain domain = AppDomain.CurrentDomain;
string myPath = Path.Combine(domain.BaseDirectory, "Company1.dll");
Assembly asm = Assembly.LoadFrom(myPath);


B. AppDomain domain = AppDomain.CurrentDomain;
string myPath = Path.Combine(domain.BaseDirectory, "Company1.dll");
Assembly asm = Assembly.Load(myPath);


C. AppDomain domain = AppDomain.CurrentDomain;
string myPath = Path.Combine(domain.DynamicDirectory, "Company1.dll");
Assembly asm = AppDomain.CurrentDomain.Load(myPath);


D. AppDomain domain = AppDomain.CurrentDomain;
Assembly asm = domain.GetData("Company1.dll");


Answer: A

Q5: You are creating a class that uses unmanaged resources. This class
maintains references to managed resources on other objects. You need to
ensure that users of this class can explicitly release resources when the
class instance ceases to be needed. Which three actions should you
perform? (Each correct answer presents part of the solution. Choose
three.)

A. Define the class such that it inherits from the WeakReference class.

B. Define the class such that it implements the IDisposable interface.

C. Create a class destructor that calls methods on other objects to release the managed resources.

D. Create a class destructor that releases the unmanaged resources.

E. Create a Dispose method that calls System.GC.Collect to force garbage collection.

F. Create a Dispose method that releases unmanaged resources and calls methods on other objects to release the managed resources.

Answer: B, D, F

Q6: You write a class named Employee that includes the following code
segment.

public class Employee
{
string employeeId, employeeName, jobTitleName;

public string GetName()
{

 return employeeName;
}

public string GetTitle()
{

 return jobTitleName;
}

}


You need to expose this class to COM in a type library. The COM interface must
also facilitate forward-compatibility across new versions of the Employee class.
You need to choose a method for generating the COM interface. What should you
do?


A. Add the following attribute to the class definition.
[ClassInterface(ClassInterfaceType.None)]
public class Employee {


B. Add the following attribute to the class definition.
[ClassInterface(ClassInterfaceType.AutoDual)]
public class Employee {


C. Add the following attribute to the class definition.
[ComVisible(true)]
public class Employee {


D. Define an interface for the class and add the following attribute to the class
definition.
[ClassInterface(ClassInterfaceType.None)]

public class Employee : IEmployee {


Answer: D
