Microsoft 70-483 Online Questions & Answers

• Question 171:

  You plan to create a list of customers named customers. Each customer will have a name and a key. The name and the key will be strings.

  You will use the following code to retrieve customers from the list.

  customers[aKey].toString();

  You need to identify which class must be used to declare the customers list. The solution must ensure that each key is unique. Which class should you identify?

  A. ArrayList
  B. Dictionary
  C. List
  D. Array
  B. Dictionary

• Question 172:

  You are developing an application that will be deployed to multiple computers. You set the assembly name.

  You need to create a unique identity for the application assembly. Which two assembly identity attributes should you include in the source code? (Each correct answer presents part of the solution. Choose two.)

  A. AssemblyTitleAttribute
  B. AssemblyCultureAttribute
  C. AssemblyVersionAttribute
  D. AssemblyKeyNameAttribute
  E. AssemblyFileVersion
  B. AssemblyCultureAttribute
  C. AssemblyVersionAttribute

  ---

  The AssemblyName object contains information about an assembly, which you can use to bind to that assembly. An assembly's identity consists of the following: Simple name Version number Cryptographic key pair Supported culture

  B: AssemblyCultureAttribute

  Specifies which culture the assembly supports.

  The attribute is used by compilers to distinguish between a main assembly and a satellite assembly. A main assembly contains code and the neutral culture's resources. A satellite assembly contains only resources for a particular culture, as

  in [assembly:AssemblyCultureAttribute("de")]

  C: AssemblyVersionAttribute

  Specifies the version of the assembly being attributed. The assembly version number is part of an assembly's identity and plays a key part in binding to the assembly and in version policy.

  *

  MatchCollection

  Represents the set of successful matches found by iteratively applying a regular expression pattern to the input string.

  The collection is immutable (read-only) and has no public constructor. The Regex.Matches method returns a MatchCollection object.

  *

  List.Add Method

  Adds an object to the end of the List.

  Incorrect:

  Not A: ICollection.SyncRoot Property

  For collections whose underlying store is not publicly available, the expected implementation is to return the current instance. Note that the pointer to the current instance might not be sufficient for collections that wrap other collections; those

  should return the underlying collection's SyncRoot property.

• Question 175:

  You have the following class definition.

  You discover that when you execute the following code, the SpawnTasks method enters an infinite loop.

  

  You discover that when you execute the following code, the SpawnTasks method enters an infinite loop.

  You need to prevent the SpawnTasks method from entering an infinite loop.

  Which two changes should you make to the code? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. Add a property to the ProcessManagement class. Modify the property to allow only positive values to be stored in the DegreeOfParallelism member variable.
  B. Add a property to the ProcessManagement class. Modify the property to allow only positive values to be stored in the NumberOfTasks member variable.
  C. Change the accessor of the ProcessManagement class to internal.
  D. Change the accessor of the DegreeOfParallelism member variable to private.
  E. Change the accessor of the SpawnTasks method to private.
  A. Add a property to the ProcessManagement class. Modify the property to allow only positive values to be stored in the DegreeOfParallelism member variable.
  B. Add a property to the ProcessManagement class. Modify the property to allow only positive values to be stored in the NumberOfTasks member variable.

• Question 176:

  DRAG DROP

  You are developing an application that implements a set of custom exception types. You declare the custom exception types by using the following code segments:

  

  The application includes a function named DoWork that throws .NET Framework exceptions and custom exceptions. The application contains only the following logging methods:

  

  The application must meet the following requirements:

  

  When ContosoValidationException exceptions are caught, log the information by using the static void Log (ContosoValidationException ex) method.

  

  When ContosoDbException or other ContosoException exceptions are caught, log the information by using the static void Log(ContosoException ex) method.

  You need to meet the requirements. You have the following code:

  

  Which code segments should you include in Target 1, Target 2 and Target 3 to complete the code? (To answer, drag the appropriate code segments to the correct targets in the answer area. Each code segment 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.)

  Select and Place:

  

  

• Question 177:

  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. DbDataAdapter
  B. unTyped DataSet
  C. OleDbDataAdapter
  D. DbDataReader
  D. DbDataReader

  A. Assembly.Load();
  B. Assembly.GetExecutingAssembly();
  C. This.GetType();
  D. Assembly.LoadFile("car.dll");
  D. Assembly.LoadFile("car.dll");

  Return a sequence of populated Animal objects.

  You need to meet the requirements.

  Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

  C. Insert the following code segment at line 13: sqlConnection.BeginTransaction();
  D. Insert the following code segment at line 16: while(sqlDataReader.Read())
  E. Insert the following code segment at line 16: while(sqlDataReader.GetValues())
  B. Insert the following code segment at line 13: sqlConnection.Open();
  D. Insert the following code segment at line 16: while(sqlDataReader.Read())

  B: SqlConnection.Open - Opens a database connection with the property settings specified by the ConnectionString. Reference: http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.open.aspx

  D: SqlDataReader.Read - Advances the SqlDataReader to the next record. Reference: http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldatareader.read.aspx

• Question 180:

  You are creating an application that manages information about your company's products. The application includes a class named Product and a method named Save.

  The Save() method must be strongly typed. It must allow only types inherited from the Product class that use a constructor that accepts no parameters.

  You need to implement the Save() method. Which code segment should you use?

  

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

  The condition new() ensures the empty/default constructor and must be the last condition.

  When you define a generic class, you can apply restrictions to the kinds of types that client code can use for type arguments when it instantiates your class. If client code tries to instantiate your class by using a type that is not allowed by a constraint, the result is a compile-time error. These restrictions are called constraints. Constraints are specified by using the where contextual keyword. http://msdn.microsoft.com/en-us/library/d5x73970.aspx
