QUESTION 3
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains
a unique solution that might meet the stated goals. Some question sets might have more than one correct solution,
while
others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not

You are developing an ASP.NET Core MVC web application.
The application must be exposed to external users over ports 80 and 443 and must meet the following requirements:
Correct Answer: A
QUESTION 4
You are developing an ASP.NET MVC 4 application that includes the following class. Line numbers are included for
reference only.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Hot Area:
Correct Answer:
Box 1: No
Line 7 executes fine as Name is the string Contoso.
Box 2: Yes
The assertion of Line 16 fails as the Boolean expression net|=0 evaluates to false (500-500 equals 0).
Note: An assertion verifies an assumption of truth for compared conditions. The assertion is central to the unit test. The
Assert class provides many static methods for verifying suppositions of truth. If the condition being verified is not true,
the
assertion fails. The Assert class throws an AssertFailedException to signal a failure.
Box 3: No
The Boolean expression on line 22, balance >= 0.0f, evaluates to 0 >=0.0f (true), as balance is set to 0.0f at line 21, and
because Contract.ensures is a postcondition.
Note: The Contract.Ensures method specifies a postcondition contract for the enclosing method or property.

You need to secure the administrative functions for all MVC controllers.
Which code segment should you use as the body for the CreateController method in AdminVerifierFactory.cs?
A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: D
The MemberInfo.CustomAttributes property gets a collection that contains this member\\’s custom attributes.
The Any() statement will either return null or a collection of matched custom attributes. If it matches one or more, the
controller is secure, otherwise an exception is thrown.
From scenario: The application contains a header that is visible on every page.
If the logged-on user is an administrator, then the header will contain links to administrative functions. This information is
read from a cookie that is set on the server. The administrative links must not be present if an error condition is present.
Incorrect:
Not B: controller.GetType().Attributes will not return custom attributes.
