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 {
