NEW QUESTION 1
You are designing a localized ASP.NET application to support multiple cultures. You need to ensure that the application can be displayed in several languages.
How should you implement this feature?

  • A. Use a resource (.resx) file.
  • B. Include language-specific content in the assembly manifest.
  • C. Use Systems.Collections.Generics.Dictionary to store alternative translations.
  • D. Ensure that all strings are marked internal.

Answer: A

NEW QUESTION 2
You are developing an ASP.NET MVC application that uses forms authentication. The application uses SQL queries that display customer order data.
You need to prevent all SQL injection attacks against the application.
How should you secure the queries?

  • A. Implement parameterization.
  • B. Pattern check the input.
  • C. Filter out prohibited words in the input.
  • D. Escape single quotes on string-based input parameters.

Answer: A

Explanation: With most development platforms, parameterized statements that work with parameters can be used (sometimes called placeholders or bind variables) instead of embedding user input in the statement. A placeholder can only store a value of the given type and not an arbitrary SQL fragment. Hence the SQL injection would simply be treated as a strange (and probably invalid) parameter value.

NEW QUESTION 3
You are building an ASP.NET application. You develop the following unit test code. Line numbers are included for reference only.
1 [TestClass]
2 public class UnitTest1 03 {
04 protected string _name; 05 protected float _expenses; 06 protected float _income; 07 protected float _payment; 08 protected float _balance;
09 public void AddCustomer(string name, float income, float payment, float balance) 10 {
11 _name = name;
12 _expenses = expenses; 13 _income = income;
14 _payment = payment; 15 _balance = balance; 16 CheckName();
17 DebRatio();
18 CheckBalance();
19 }
20 [TestMethod]
21 public void CheckName() 22 {
23 Assert.IsNotNull(_name, “CheckName failed unit test”); 24 }
25 [TestMethod]
26 public void DebRatio() 27 {
28 Assert.AreSame(_income, _payment, “DebRatio failed unit test”); 29 }
30 [TestMethod]
31 public void CheckBalance() 32 {
33 Assert.IsTrue(_balance >= 0.0f, Check balance failed unit test.”); 34 }
35}
You run the following line of code: AddCustomer(“Contoso”, 0, 100, 100, -1);
You need to evaluate the unit test results. For each of the following statements, select Yes if the statement is true. Otherwise, select No.

    Answer:

    Explanation: Box 1: Yes
    Line 23 is Assert.IsNotNull(_name, “CheckName failed unit test”);
    _name is "Contoso" so the assertion will succeed. Box 2: No
    Line 289 is Assert.AreSame(_income, _payment, “DebRatio failed unit test”);
    _income is 0 and payment is 100. The assertion will fail. Box 3: No
    Line 33 is Assert.IsTrue(_balance >= 0.0f, Check balance failed unit test.”);
    _balance is -1. The assertion will fail.

    NEW QUESTION 4
    You are developing an ASP.NET MVC web application.
    You need to create a form that can be used to add new products to the web application. You have the following markup:
    70-486 dumps exhibit
    Which markup segments should you include in Target 1, Target 2, Target 3 and Target 4 to complete the markup? To answer, drag the appropriate markup segments to the correct targets. Each markup 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.
    70-486 dumps exhibit

      Answer:

      Explanation: Target 1: <form action="/Products/Create" method="post"> The form methods are post and get (not submit).
      Target 2: <td>@Html.Textbox(@Model.ProductName)</td>
      The InputExtensions.TextBox method returns a text input element. The TextBox method is designed to make it easy to bind to view data or model data.
      Target3: <td>@Html.Textbox(@Model.UnitPrice)</td>
      The InputExtensions.TextBox method returns a text input element. The TextBox method is designed to make it easy to bind to view data or model data.
      Target 4: <input type="submit" value="Save"/>
      The submitattribute, of input type, declares a submit button. The input type attribute does not have a post attribute. References:

        Explanation: Configuring the debugger to break for first chance exceptions
        To change when the debugger breaks, go to Debug->Exceptions…
        70-486 dumps exhibit
        When you first open this window you will see that there is a tree grid with one column and checkboxes.
        * Break when Thrown. This includes a default list of exceptions known by the debugger, grouped by category. Note: The possible exceptions that could break from this list is determined by the runtime you are debugging.
        For example, if you are using managed-only debugging then the debugger will never break for C++, Win32
        Exceptions, etc. even if they are configured to break when thrown.
        * Checkboxes. If you check the box for a category, then the debugger will break for all First Chance Exceptions while debugging. If you don’t want to enable all First Chance Exceptions, you can find the specific exception types that you wish to configure by using the search box.
