• Question 101:

  You are developing an application that retrieves patient data from a web service. The application stores the JSON messages returned from the web service in a string variable named PatientAsJson. The variable is encoded as UTF-8. The application includes a class named Patient that is defined by the following code:

  

  You need to populate the Patient class with the data returned from the web service. Which code segment should you use?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

• Question 102:

  DRAG DROP

  An application serializes and deserializes XML from streams. The XML streams are in the following format:

  

  The application reads the XML streams by using a DataContractSerializer object that is declared by the following code segment:

  var ser = new DataContractSerializer(typeof(Name));

  You need to ensure that the application preserves the element ordering as provided in the XML stream.

  How should you complete the relevant code? (To answer, drag the appropriate attributes to the correct locations in the answer area-Each attribute may be used once, more than once, or not at all. You may need to drag the split bar between

  panes or scroll to view content.)

• Question 103:

  You have two assemblies named Assembly1 and Assembly2 that are written in C#. Assembly1 loads Assembly2 by executing the following code.

  

  You create a new project in Microsoft Visual Studio to build a new assembly that will replace Assembly2. The new assembly has the same name and version as the original Assembly2 assembly.

  When you execute the code, Assembly1 cannot load Assembly2.

  What should you do to ensure that Assembly1 can load Assembly2?

  A. Modify the project properties. Click Sign the assembly and select a new key file.
  B. Run the sn.exe command to create a new key file. Run the al.exe command to sign Assembly2 by using the generated key file.
  C. Use the sn.exe command to create a new key file. Set the assembly:AssemblyKeyFileAttribute attribute to the new key file.
  D. Run the al.exe command to sign Assembly2. Use the same key file used for the original Assembly2 assembly.
  E. Modify the project properties. Click Delay sign only.
  F. Add the new Assembly2 assembly to the global assembly cache
  D. Run the al.exe command to sign Assembly2. Use the same key file used for the original Assembly2 assembly.

• Question 104:

  You have a List object that is generated by executing the following code:

  

  You have a method that contains the following code (line numbers are included for reference only):

  

  You need to alter the method to use a lambda statement. How should you rewrite lines 03 through 06 of the method?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  C. Option C

  This returns a bool and will work fine.

  Incorrect:

  Not A: This returns a string.

  Not B, not D: These return IEnumerable.

• Question 105:

  An application uses X509 certificates for data encryption and decryption. The application stores certificates in the Personal certificates collection of the Current User store. On each computer, each certificate subject is unique. The application includes a method named LoadCertificate. The LoadCertificate() method includes the following code. (Line numbers are included for reference only.)

  

  The LoadCertificate() method must load only certificates for which the subject exactly matches the searchValue parameter value.

  You need to ensure that the LoadCertificate() method loads the correct certificates.

  Which code segment should you insert at line 06?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

  X509FindType.FindBySubjectDistiguishedName is a more specific search than that provided by the FindBySubjectName enumeration value. Using the FindBySubjectDistinguishedName value, the Find method performs a case-insensitive string comparison for the entire distinguished name. Searching by subject name is a less precise search.

• Question 106:

  You are developing an application that contains a class named TheaterCustomer and a method named ProcessTheaterCustomer. The ProcessTheaterCustomer() method accepts a TheaterCustomer object as the input parameter.

  You have the following requirements:

  Store the TheaterCustomer objects in a collection. Ensure that the ProcessTheaterCustomer() method processes the TheaterCustomer objects in the reverse order in which they are placed into the collection.

  You need to meet the requirements.

  What should you do?

  A. Create a System.Collections.Queue collection. Use the Enqueue() method to add TheaterCustomer objects to the collection. Use the Dequeue() method to pass the objects to the ProcessTheaterCustomer() method.
  B. Create a System.Collections.ArrayList collection. Use the Insert() method to add TheaterCustomer objects to the collection. Use the Remove() method to pass the objects to the ProcessTheaterCustomer() method.
  C. Create a System.Collections.Stack collection. Use the Push() method to add TheaterCustomer objects to the collection. Use the Pop() method to pass the objects to the ProcessTheaterCustomer() method.
  D. Create a System.Collections.Queue collection. Use the Enqueue() method to add TheaterCustomer objects to the collection. Use the Peek() method to pass the objects to the ProcessTheaterCustomer() method.
  C. Create a System.Collections.Stack collection. Use the Push() method to add TheaterCustomer objects to the collection. Use the Pop() method to pass the objects to the ProcessTheaterCustomer() method.

  A stack is the appropriate collection here. In computer science, a stack or LIFO (last in, first out) is an abstract data type that serves as a collection of elements, with two principal operations: push, which adds an element to the collection, and pop, which removes the last element that was added.

• Question 107:

  HOTSPOT

  You are evaluating the following C# method.

• Question 109:

  You are troubleshooting an application that uses a class named FullName. The class is decorated with the DataContractAttribute attribute. The application includes the following code. (Line numbers are included for reference only.)

  

  You need to ensure that the entire FullName object is serialized to the memory stream object.

  Which code segment should you insert at line 09?

  A. binary.WriteEndDocument();
  B. binary.WriteEndDocumentAsync();
  C. binary.WriteEndElementAsync();
  D. binary.Flush();
  E. binary.WriteEndElement();
  F. ms.Close();
  G. ms.Flush();
  A. binary.WriteEndDocument();

  DataContractSerializer.WriteEndObject Method (XmlDictionaryWriter) Writes the closing XML element using an XmlDictionaryWriter.

  Note on line 07: DataContractSerializer.WriteObject Method

  Writes all the object data (starting XML element, content, and closing element) to an XML document or stream.

• Question 110:

  You are developing an application.

  The application contains the following code:

  

  When you compile the code, you receive the following syntax error message: "A previous catch clause already catches all exceptions of this or a super type ('System.Exception')." You need to ensure that the code can be compiled. What should you do?

  A. Catch the ArgumentException exception instead of the ArgumentNullException exception.
  B. Throw a new exception in the second catch block.
  C. Catch the ArgumentNullException exception first.
  D. Re-throw the exception caught by the second catch block.
  A. Catch the ArgumentException exception instead of the ArgumentNullException exception.
