Question: You are creating a new security policy for an application domain. You write the following lines of code.
PolicyLevel =policy = PolicyLevel::CreateAppDomainLevel();
PolicyStatement =noTrustStatement =
gcnew PolicyStatement(
policy->GetNamedPermissionSet("Nothing"));
PolicyStatement =fullTrustStatement =
gcnew PolicyStatement(
policy->GetNamedPermissionSet("FullTrust"));
You need to arrange code groups for the policy so that loaded assemblies default to the Nothing permission set. If the assembly originates from a trusted zone, the security policy must grant the assembly the FullTrust permission set.
Which code segment should you use?
A
CodeGroup =group1 = gcnew FirstMatchCodeGroup(
gcnew ZoneMembershipCondition(SecurityZone::Trusted), fullTrustStatement);
CodeGroup =group2 = gcnew UnionCodeGroup(
gcnew AllMembershipCondition(),
noTrustStatement);
group1->AddChild(group2);

B
CodeGroup =group = gcnew FirstMatchCodeGroup(
gcnew AllMembershipCondition(),
noTrustStatement);

C
CodeGroup =group = gcnew UnionCodeGroup(
gcnew ZoneMembershipCondition(SecurityZone::Trusted), fullTrustStatement);

D
CodeGroup =group1 = gcnew FirstMatchCodeGroup(
gcnew AllMembershipCondition(),
noTrustStatement);
CodeGroup =group2 = gcnew UnionCodeGroup(
gcnew ZoneMembershipCondition(SecurityZone::Trusted), fullTrustStatement);
group1->AddChild(group2);

Question:
You create a class library that is used by applications in three departments of your company. The library contains a Department class with the following definition.
public class Department {
public string name;
public string manager;
}
Each application uses a custom configuration section to store department-specific values in the application configuration file as shown in the following code.
<Department>
<name>Hardware</name>
<manager>Amy</manager>
</Department>
You need to write a code segment that creates a Department object instance by using the field values retrieved from the application configuration file.
Which code segment should you use?
A
public class deptElement: ConfigurationElement {
protected override void DeserializeElement(
XmlReader reader, bool serializeCollectionKey) {
Department dept = new Department();
dept.name = reader.GetAttribute("name");
dept.manager = reader.GetAttribute("manager");
}
}

B
public class deptHandler : IConfigurationSectionHandler { public object Create(object parent, object configContext, System.Xml.XmlNode section) {
Department dept = new Department();
dept.name = section.Attributes["name"].Value;
dept.manager = section.Attributes["manager"].Value;
return dept;
}
}

C
public class deptElement : ConfigurationElement {
protected override void DeserializeElement(
XmlReader reader, bool serializeCollectionKey) {
Department dept = new Department(); dept.name = ConfigurationManager.AppSettings["name"]; dept.manager = ConfigurationManager.AppSettings["manager"];
return dept;
}
}

D
public class deptHandler : IConfigurationSectionHandler { public object Create(object parent, object configContext, System.Xml.XmlNode section) {
Department dept = new Department();
dept.name = section.SelectSingleNode("name").InnerText; dept.manager =
section.SelectSingleNode("manager").InnerText;
return dept;

Question:
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.contoso.com.
To test the application, you use a source address, me@contoso.com, and a target address, you@contoso. com.
You need to transmit the e-mail message.
Which code segment should you use?
A
MailAddress addrFrom =
new MailAddress("me@contoso.com", "Me");
MailAddress addrTo =
new MailAddress("you@contoso.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);

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

C
string strSmtpClient = "smtp.contoso.com";
string strFrom = "me@contoso.com";
string strTo = "you@contoso.com";
string strSubject = "Greetings!";
string strBody = "Test";
MailMessage msg =
new MailMessage(strFrom, strTo, strSubject, strSmtpClient);

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