You have just graduated from college,now you are serving the internship as the software developer in an international company. There,s an array of bytes that is passed to the method in a parameter named document. You are writing a method to compress the array.now according to the manager requirements, you have to compress the contents of the incoming parameter. In the options below, which code segment should you use?

• A. Dim objStream As New MemoryStream(document)Dim zipStream As New GZipStream( _objStream, CompressionMode.Compress)Dim outStream As New MemoryStreamDim b As IntegerWhile (b = zipStream.ReadByte)outStream.WriteByte(CByte(b))End WhileReturn outStream.ToArray
• B. Dim objStream As New MemoryStream(document)Dim zipStream As New GZipStream( _ objStream, CompressionMode.Compress)zipStream.Write(document, 0, document.Length)zipStream.Close()Return objStream.ToArray
• C. Dim outStream As New MemoryStreamDim zipStream As New GZipStream( _outStream, CompressionMode.Compress)zipStream.Write(document, 0, document.Length)zipStream.Close()Return outStream.ToArray
• D. Dim inStream As New MemoryStream(document)Dim zipStream As New GZipStream( _inStream, CompressionMode.Compress)Dim result(document.Length) As BytezipStream.Write(result, 0, result.Length)Return result

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 according to the customer requirement, you are creating an application. The application will deploy by using ClickOnce. After the application is created, the customer wants to see whether the application runs properly. So you have to test it. You have to write a method that returns the object, which prompts the user to install a ClickOnce application. In the options below, which code segment should you use?

• A. return SecurityManager.PolicyHierarchy();
• B. return AppDomain.CurrentDomain.ApplicationTrust;
• C. return ApplicationSecurityManager.ApplicationTrustManager;

You have just graduated from college, now you are serving the internship as the software developer in an international company. According to the requirements of the company CIO, you create a personalized home page. You plan to enable users to choose from a selection of daily headlines from different news providers. You create a series of custom user controls each of which points to a different news provider. You have to add these controls to the personalized home page. What should you do?

• A. The controls should be added to a CatalogZone.
• B. The controls should be added to a PageCatalogPart.
• C. The controls should be added to a WebPartZone.
• D. The controls should be added to a WebPartManager.

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: [XmlArray(ElementName="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: [XmlElement(Type = typeof(Employees))]
