    70-483 dumps exhibit
    For each of the following properties, select Yes if the property is serialized according to the defined schema. Otherwise, select No.
    70-483 dumps exhibit

      Answer:

      Explanation: OrderId – NO (this will serialize as an element, not as aa attribute)
      OrderDate – NO (doesn't have DataMember attribute, thus is completely ignored) CustomerName – YES (DataMember is set correctly)

      NEW QUESTION 3
      You are developing an application by using C#.
      The application includes an object that performs a long running process.
      You need to ensure that the garbage collector does not release the object's resources until the process completes.
      Which garbage collector method should you use?

      • A. RemoveMemoryPressure()
      • B. ReRegisterForFinalize()
      • C. WaitForFullGCComplete()
      • D. KeepAlive()

      Answer: D

      Explanation: The purpose of the KeepAlive method is to ensure the existence of a reference to an object that is at risk of being prematurely reclaimed by the garbage collector.
      Reference: GC.KeepAlive Method (Object)

      Answer: A

      Explanation: The MatchCollection.GetEnumerator method returns an enumerator that iterates through a collection.
      Note:
      The MatchCollection Class represents the set of successful matches found by iteratively applying a regular expression pattern to the input string.
      Incorrect:
      Not B: The ICollection.SyncRoot property gets an object that can be used to synchronize access to the ICollection.
      Reference: MatchCollection.GetEnumerator Method https://msdn.microsoft.com/enus/ library/system.text.regularexpressions.matchcollection.getenumerator(v=vs.110).aspx

      NEW QUESTION 5
      You are developing an application.
      The application contains the following code segment (line numbers are included for reference only):
      70-483 dumps exhibit
      When you run the code, you receive the following error message: "Cannot implicitly convert type 'object'' to 'inf. An explicit conversion exists (are you missing a cast?)."
      You need to ensure that the code can be compiled. Which code should you use to replace line 05?

      • A. var2 = ((List<int>) array1) [0];
      • B. var2 = array1[0].Equals(typeof(int));
      • C. var2 = Convert.ToInt32(array1[0]);
      • D. var2 = ((int[])array1)[0];

      Answer: C

      Explanation: The Convert.ToInt32 method converts a specified value to a 32-bit signed integer. Reference: https://msdn.microsoft.com/en-us/library/system.convert.toint32(v=vs.110).aspx

      NEW QUESTION 6
      You use the Task.Run() method to launch a long-running data processing operation. The data processing operation often fails in times of heavy network congestion.
      If the data processing operation fails, a second operation must clean up any results of the first operation.
      You need to ensure that the second operation is invoked only if the data processing operation throws an unhandled exception.
      What should you do?

      • A. Create a TaskCompletionSource<T> object and call the TrySetException() method of the object.
      • B. Create a task by calling the Task.ContinueWith() method.
      • C. Examine the Task.Status property immediately after the call to the Task.Run() method.
      • D. Create a task inside the existing Task.Run() method by using the AttachedToParent optio

      Answer: B

      Explanation: Task.ContinueWith - Creates a continuation that executes asynchronously when the target Task completes.The returned Task will not be scheduled for execution until the current task has completed, whether it completes due to running to completion successfully, faulting due to an unhandled exception, or exiting out early due to being canceled.

      NEW QUESTION 8
      You are developing an application. The application includes classes named Mammal and Animal and an interface named IAnimal.
      The Mammal class must meet the following requirements:
      It must either inherit from the Animal class or implement the IAnimal interface. It must be inheritable by other classes in the application.
      You need to ensure that the Mammal class meets the requirements.

      NEW QUESTION 9
      You need to write a method that retrieves data from a Microsoft Access 2013 database. The method must meet the following requirements:
      Be read-only.
      Be able to use the data before the entire data set is retrieved.
      Minimize the amount of system overhead and the amount of memory usage. Which type of object should you use in the method?

      • A. SqlDataAdapter
      • B. DataContext
      • C. DbDataAdapter
      • D. OleDbDataReader

      Answer: D

      Explanation: OleDbDataReader Class
      Provides a way of reading a forward-only stream of data rows from a data source. Example:
      OleDbConnection cn = new OleDbConnection(); OleDbCommand cmd = new OleDbCommand(); DataTable schemaTable;
      OleDbDataReader myReader;
      //Open a connection to the SQL Server Northwind database.

      NEW QUESTION 11
      HOTSPOT
      You are developing the following classes named: Class1
      Class2 Class3
      All of the classes will be part of a single assembly named Assembly.dll. Assembly.dll will be used by multiple applications.
      All of the classes will implement the following interface, which is also part ofAssembly.dll: public interface Interface1
      {
      void Method1(decimal amount); void Method2(decimal amount);
      }
      You need to ensure that the Method2 method for the Class3 class can be executed only when instances of the class are accessed through the Interface1 interface. The solution must ensure that calls to the Method1 method can be made either through the interface or through an instance of the class.
      Which signature should you use for each method? (To answer, select the appropriate signature for each method in the answer area.)

        NEW QUESTION 12
        HOTSPOT
        You have the following code:
        70-483 dumps exhibit
        For each of the following statements, select Yes if the statement is true. Otherwise, select No.
        70-483 dumps exhibit

          Answer:

          Explanation: Note:
          * CustomerID is declared private.
          * CompanyName is declted protected.
          * State is declared protected.
          The protected keyword is a member access modifier. A protected member is accessible from within the class in which it is declared, and from within any class derived from the class that declared this member.

          Explanation: The JavaScriptSerializer Class Provides serialization and deserialization functionality for AJAXenabled applications.
          The JavaScriptSerializer class is used internally by the asynchronous communication layer to serialize and deserialize the data that is passed between the browser and the Web server. You cannot access that instance of the serializer. However, this class exposes a public API. Therefore, you can use the class when you want to work with JavaScript Object Notation (JSON) in managed code.
          Incorrect:
          Not B, not C: The NetDataContractSerializer works with XML, but not with JSON.

            You are developing an application by using C#. You provide a public key to the development team during development.
            You need to specify that the assembly is not fully signed when it is built.
            Which two assembly attributes should you include in the source code? (Each correct answer presents part of the solution. Choose two.)

            Explanation: * AssemblyDelaySignAttribute
            Specifies that the assembly is not fully signed when created.
            * The following code example shows the use of the AssemblyDelaySignAttribute attribute with the AssemblyKeyFileAttribute.
            using System;
            using System.Refilection; [assembly:AssemblyKeyFileAttribute(“TestPublicKey.snk”)] [assembly:AssemblyDelaySignAttribute(true)]
