Question:
You are creating a new security policy for an application domain. You write the following lines of code.
Dim objPolicy As PolicyLevel = PolicyLevel.CreateAppDomainLevel
Dim noTrustStatement As New PolicyStatement( _
objPolicy.GetNamedPermissionSet("Nothing"))
Dim fullTrustStatement As New PolicyStatement( _
objPolicy.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
Dim objGroup As CodeGroup = New UnionCodeGroup( _
New ZoneMembershipCondition(SecurityZone.Trusted), _ fullTrustStatement)

B
Dim objGroup1 As CodeGroup = New FirstMatchCodeGroup( _ New AllMembershipCondition, noTrustStatement)
Dim objGroup2 As CodeGroup = New UnionCodeGroup( _
New ZoneMembershipCondition(SecurityZone.Trusted), _ fullTrustStatement)

C
Dim objGroup As CodeGroup = New FirstMatchCodeGroup( _ New ZoneMembershipCondition (SecurityZone.Trusted), _ fullTrustStatement)

D
Dim objGroup1 As CodeGroup = New FirstMatchCodeGroup( _ New ZoneMembershipCondition (SecurityZone.Trusted), _ fullTrustStatement)

Question: You need to write a code segment that transfers the first 80 bytes from a stream variable named stream1 into a new byte array named byteArray. You also need to ensure that the code segment assigns the number of bytes that are transferred to an integer variable named bytesTransferred. Which code segment should you use?
A
stream1->Write(byteArray, 0, 80); bytesTransferred = byteArray->Length;

B
bytesTransferred = stream1->Read(byteArray, 0, 80);

C
while (bytesTransferred < 80) {
stream1->Seek(1, SeekOrigin::Current);
byteArray[bytesTransferred++] =
Convert::ToByte(stream1->ReadByte());

Question:
You deploy several ,NET-connected applications to a shared folder on your company network. Your applications require full trust to execute correctly. Users report that they receive security exceptions when they attempt to run the applications on their computers.
You need to ensure that the applications on the users' computers run with full trust.
What should you do?

A
Grant the full trust permission set to the Trusted Zone code group by using the Code Access Security Policy tool (Caspol.exe).

B
Use the security settings of Internet Explorer to add the shared folder to the list of trusted sites.

C
Apply a strong name to the applications by using the Strong Name tool (Sn.exe).

D
Use the Code Access Security Policy tool (Caspol.exe) to add a new code group that has the full trust permission set. The new code group must also contain a URL membership condition that specifies the URL of the shared folder where your applications reside.

Question:
You are creating an assembly that interacts with the file system.
You need to configure a permission request so that the common language runtime (CLR) will stop loading the assembly if the necessary file permissions are absent.
Which attribute should you place in your code?
A
<Assembly: FileIOPermission( SecurityAction.RequestOptional,_ AllLocalFiles: FileIOPermissionAccess.Read) >

B
<Assembly: FileIOPermission( SecurityAction.RequestOptional,_ AllFiles=FileIOPermissionAccess. Read)_ >

C

Question:
You are developing an application that runs by using the credentials of the end user. Only users who are members of the Administrator group get permission to run the application. You write the following security code to protect sensitive data within the application.
Dim blnAdmin As Boolean = False
Dim objRole As WindowsBuiltlnRole =
WindowsBuiltInRole.Administrator
If blnAdmin = False Then
Throw New Exception("User not permitted")
End If
You need to add a code segment to this security code to ensure that the application throws an exception if a user is not a member of the Administrator group.
Which code segment should you use?
A
Dim objUser As UindowsPrincipal =
DirectCast(Thread.CurrentPrincipal, WindowsPrincipal) blnAdmin = objUser.IsInRole(objRole)

B
Dim objUser As GenericPrincipal =
DirectCast(Thread.CurrentPrincipal, GenericPrincipal) blnAdmin = objUser.IsInRole(objRole.ToString)

C
Dim objUSer As Windowsldentity =
DirectCast(Thread.CurrentPrincipal.Identity, Windowsldentity) blnAdmin = objUSer.Name.EndsUith ("Administrator")

D
Dim objUser As WindowsIdentity = WindowsIdentity.GetCurrent For Each objGroup As IdentityReference In objUser.Groups Dim objAccount As NTAccount =
DirectCast(objGroup.Translate(
Type.GetType("NTAccount")),NTAccount)
blnAdmin = objGroup.Value.Equals(objRole)
