1. 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 outStream As New MemoryStreamDim zipStream As New GZipStream( _outStream, CompressionMode.Compress)zipStream.Write(document, 0, document.Length)zipStream.Close()Return outStream.ToArray
B) 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
C) 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
D) 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

2. 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 a method to hash data with the Secure Hash Algorithm. The data is passed to your method as a byte array named message. You have to use SHA1 to compute the hash of the incoming parameter. Besides this, the result has to be placed into a byte array named hash. In the options below, which code segment should you use?

A) SHA1 sha = new SHA1CryptoServiceProvider();byte[] hash = null;sha.TransformBlock( message, 0, message.Length, hash, 0);
B) SHA1 sha = new SHA1CryptoServiceProvider();byte[] hash = BitConverter.GetBytes(sha.GetHashCode());
C) SHA1 sha = new SHA1CryptoServiceProvider();byte[] hash = sha.ComputeHash(message);
D) SHA1 sha = new SHA1CryptoServiceProvider();sha.GetHashCode();byte[] hash = sha.Hash;

3. You work as the developer in an IT company. Recently your company has a client. The client needs a class. Your company asks you to develop a custom-collection class. In this class, a method has to be created. After the method has been created, the method has to return a type. And the type should be compatible with the Foreach statement.
Which criterion should the method meet?

A) The method must explicitly contain a collection.
B) The method must be the only iterator in the class.
C) The method must return a type of IComparable.
D) The method must return a type of either IEnumerator or IEnumerable.

4. You work as the developer in an IT company. Recently your company has business with a big client. The client is a big supermarket chain. The client needs an application to store data about its selling records. Your company assigns this task to you. When details about a specific team are queried by a user, the name and contact information for each person must be available as a single collection. Besides this, the data collection must guarantee type safety. You must ensure these, in the options below, which code segment should you use?

A) Hashtable team = new Hashtable();team.Add(1, "Hance");team.Add(2, "Jim");team.Add(3, "Hanif");team.Add(4, "Kerim");team.Add(5, "Alex");team.Add(6, "Mark");team.Add(7, "Roger");team.Add(8, "Tommy");
B) Dictionary<int, string> team = new Dictionary<int, string>(); team.Add(1, "Hance");team.Add(2, "Jim");team.Add(3, "Hanif");team.Add(4, "Kerim");team.Add(5, "Alex");team.Add(6, "Mark");team.Add(7, "Roger");team.Add(8, "Tommy");
C) ArrayList team = new ArrayList(); team.Add("1, Hance");team.Add("2, Jim");team.Add("3, Hanif");team.Add("4, Kerim");team.Add("5, Alex");team.Add("6, Mark");team.Add("7, Roger");team.Add("8, Tommy");
D) string[] team = new string[] {"1, Hance", "2, Jim", "3, Hanif", "4, Kerim", "5, Alex", "6, Mark", "7, Roger", "8, Tommy"};

5. 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. You have to compress the incoming array of bytes and return the result as an array of bytes. In the options below, which segment should you use?

A) Dim objStream As New MemoryStream(document)Dim objDeflate As New DeflateStream(objStream, CompressionMode.Compress)objDeflate.Write(document, 0, document.Length)objDeflate.Close()Return objStream.ToArray
B) Dim objStream As New MemoryStream()Dim objDeflate As New DeflateStream(objStream, CompressionMode.Compress)objDeflate.Write(document, 0, document.Length)objDeflate.Close()Return objStream.ToArray
C) Dim objStream As New MemoryStream(document)Dim objDeflate As New DeflateStream(objStream, CompressionMode.Compress)Dim result(document.Length) As ByteobjDeflate.Write(result, 0, result.Length)Return result
D) Dim objStream As New MemoryStream()Dim objDeflate As New DeflateStream(objStream, CompressionMode.Compress)Dim outStream As New MemoryStreamDim b As IntegerWhile (b = objDeflate.ReadByte) outStream.WriteByte(CByte(b))End WhileReturn outStream.ToArray
