You work as the developer in an IT company. Recently your company has a big customer. The customer runs a large supermarket chain. You're appointed to provide technical support for the customer. Now you are managing user accounts for a Web site by using the ASP.NET membership APIs. The definition for the membership provider is contained in the Web.config file. You create a PasswordReset.aspx file after modifying the Web.config file to enable password recovery. Users must reset their passwords online. And after the users have logged on through the Login.aspx page, the new passwords must be sent to them by e-mail. Besides this, before users reset their passwords, users must be required to answer their secret questions. Which code logic should you use?

• A.You should modify the Page_Load to set the Membership.EnablePasswordReset to True in the PasswordReset.aspx file.
• B.You should add a ChangePassword element to the PasswordReset.aspx file and configure it.
• C.You should modify the Login.aspx form to include a Required Field validator on the secret question answer text box. Then redirect users to the PasswordReset.aspx file.

You work as the developer in an IT company. Recently your company has a big customer. The customer runs a large supermarket chain. You're appointed to provide technical support for the customer. Now you are creating a class library according to the customer requirement. The class library contains the class hierarchy defined in the following code segment. (Line numbers are included for reference only.)
1 public class Group {
2 public Employee[] Employees;
3 }
4 public class Employee {
5 public string Name;
6 }
7 public class Manager : Employee {
8 public int Level;
9 }
You create an instance of the Group class then populate the fields of the instance. You receive InvalidOperationException when you use the Serialize method of the XmlSerializer class to serialize the instance. Besides this, you receive the following error message: "There was an error generating the XML document."
In order to successfully use the XmlSerializer class to serialize instances of the Group class, you have to modify the code segment. And you must make sure that the XML output contains an element for all public fields in the class hierarchy.
What should you do?

• A.Insert the following code between lines 1 and 2 of the code segment: [XmlElement(Type = typeof(Employees))]
• B.Insert the following code between lines 1 and 2 of the code segment: [XmlArrayItem(Type = typeof(Employee))] [XmlArrayItem(Type = typeof(Manager))]
• C.Insert the following code between lines 3 and 4 of the code segment: [XmlElement(Type = typeof(Employee))] andInsert the following code between lines 6 and 7 of the code segment: [XmlElement(Type = typeof(Manager))]
• D.Insert the following code between lines 1 and 2 of the code segment: [XmlArray(ElementName="Employees")]

• B.ApplicationTrustCollection trusts;trusts = ApplicationSecurityManager.UserApplicationTrusts; foreach (ApplicationTrust trust in trusts) { Console.WriteLine(trust.ApplicationIdentity.FullName);}
• C.ApplicationTrustCollection trusts;trusts = ApplicationSecurityManager.UserApplicationTrusts; foreach (ApplicationTrust trust in trusts) { Console.WriteLine(trust.ExtraInfo.ToString());}
• D.ApplicationTrustCollection trusts;trusts = ApplicationSecurityManager.UserApplicationTrusts; foreach (object trust in trusts) { Console.WriteLine(trust.ToString());}

• B.Dim objTrusts As ApplicationTrustCollectionobjTrusts = ApplicationSecurityManager.UserApplicationTrustsFor Each objTrust As Object In objTrusts Console.WriteLine(objTrust.ToString)Next
• C.Dim objTrusts As ApplicationTrustCollectionobjTrusts = ApplicationSecurityManager.UserApplicationTrustsFor Each objTrust As ApplicationTrust In objTrusts Console.WriteLine(objTrust.ToString)Next
• D.Dim objTrusts As ApplicationTrustCollectionobjTrusts = ApplicationSecurityManager.UserApplicationTrustsFor Each objTrust As ApplicationTrust In objTrusts Console.WriteLine(objTrust.ExtraInfo.ToString)Next
