Topic 2, Scenario 2
Background
You are making use of Visual Studio 2012 to create an ASP.NET MVC online retail web
application.
Business Prerequisites
The entering of user e-mail addresses should not be compulsory. In the event that a user does
provide an e-mail address, the validity of the address should be authenticated. To motivate users
to keep on browsing the item list, you have to make sure that the first item on the item page
gradually disappears.
Furthermore, you have to make sure that administrators have the ability to manage current client
data, and also identify a default item on the item page.
Technical Prerequisites
General:
A load-balanced web farm, where the load balancer has not been configured to employ server
affinity, hosts the application
With regards to items, you are informed that the itemId property value should not be less than or
equal to 0. Furthermore, the Items page for mobile devices should be presented to mobile users
and the Items page for desktop computers should be presented to desktop users
Storage:
You are informed that information should be saved in a serialized XML data format, and that
serialized objects should be independent of the schema.
Exception handling:
A page showing support contact details should be presented for IIS exceptions. 404 errors
resulting from expired links cause exceptions to be thrown. Some page links expire, and users
who access these links encounter 404 errors. The WriteLog method of the Utility class should be
used to log these exceptions.
Browser and device support:
The application should allow for .bmp format images to be changed to .jpeg format images for
mobile devices, and to .png format images for desktop computers.
************************************
You have received instructions to apply client-side animations. You want to make sure that the
business prerequisites are suitably met.
Which of the following should be included in your code?
A.
You should consider including the :first-child pseudo-class.
B.
You should consider including the :nth-child pseudo-class.
C.
You should consider including the :nth-last-child(n) pseudo-class.
D.
You should consider including the :last-child pseudo-class.
why not A, since it was mentioned that the first item in the list.
I have the same question. To my opinion it is A. But everywhere on the internet I find that B is the correct answer, but I don’t understand why A isn’t the correct answer.
Tomorrow exam…..
The reason is that you are fading out the second in the table. The first is the header row e.g.
$(“body table tr:nth-child(2)”).fadeOut(“slow”);
or
$(“body table tr:nth-child(2)”).animate({ opacity: 0 });
but animate only seems to work correctly in chrome at the moment.
I go to see day-to-day some sites and websites to read content, but this blog gives feature based content.|

B. In the web.config file, set the value of the debug attribute to True.
C. Enable Browser link.
D. Use an external editor for webpages.
E. Enable source control server support.
Answer: BC
Explanation:
Debugging must be enabled in the web.config file. To enable Browser Link, set debug=true in the element in the project’s Web.config file.
NEW QUESTION 200
You develop an ASP.NET MVC application. The application is configured for claims-based authentication by using Windows Identity Foundation (WIF). You need to access the claims in the WIF token. Which code segment should you use?
A. Thread.CurrentPrincipal.Identity;
B. ((IClaimsPrincipal)Thread.CurrentPrincipal).Identities[0].Claims;
C. Thread.CurrentPrincipal;
D. ((IClaimsPrincipal)Thread.CurrentPrincipal).Identities[0].IsAuthenticated;
Answer: B
Explanation:
To Access the Claims
In order to access identity related information, you can run FedUtil. Once you have run FedUtil, your application can access IClaimsPrincipal and IClaimsIdentity using the standard ASP.NET constructs as shown in the following code example:
void Page_Load(object sender, EventArgs e)
{
// Cast the Thread.CurrentPrincipal
IClaimsPrincipal icp = Thread.CurrentPrincipal as IClaimsPrincipal; // Access IClaimsIdentity which contains claims
IClaimsIdentity claimsIdentity = (IClaimsIdentity)icp.Identity; // Access claims
foreach(Claim claim in claimsIdentity.Claims)
{
}
}
NEW QUESTION 201
You are developing an ASP.NET MVC application. The application has a contact view includes a form for editing the displayed contact. You need to save the Contact object model when the form is posted back to the EditContact method using a POST method request. Which code segment should you use? (Each correct answer presents a complete solution. Choose all that apply.)
A. public ActionResult EditContact(){var c = newContact(){FirstName = Request.QueryString [‘”FirstName”‘],LastName = Request.QueryString[“LastName”]},SaveContact(c);return View(c);}
B. public ActionResult EditContact(Contact c){SaveContact(c);return View(c);}
C. public ActionResult EditContact(FormCollection values){var c = newContact(){FirstName = values [‘”FirstName”‘],LastName = values[“LastName”]},SaveContact(c);return View(c);}
D. public ActionResult EditContact(QueryStringProvider values){var c = newContact(){FirstName = values.GetValue[‘”FirstName”‘],LastName = values.GetValue [“LastName”]},SaveContact(c);return View (c);}
Answer: AB
NEW QUESTION 203
You are developing an ASP.NET MVC application. The application uses a set of custom exceptions to log errors that occur during the execution of an action. You need to develop a class that implements logging. Which interface should you implement?
A. IExceptionFilter
B. IActionFilter
C. IClientValidatable
D. IResultFilter
Answer: A
Explanation:
Exception filters are used to apply global policies to unhandled exceptions in the MVC app. Exception Filters implement either the IExceptionFilter or IAsyncExceptionFilter interface. Exception filters handle unhandled exceptions, including those that occur during controller creation and model binding. They are only called when an exception occurs in the pipeline.
NEW QUESTION 204
You create an ASP.NET MVC application. You host the application by using the Open Web Interface for .NET (OWIN).
You run the following command by using the NuGet Package Manager console:
install-package Microsoft.AspNet.SignalR
You plan to implement real-time push notifications from the server using ASP.NET SignalR. You need to complete the ASP.NET SignalR implementation. Which three steps should you perform? Each correct answer presents part of the solution.
A. Create a hub class to push content to clients.
B. Create a class that derives from the PersistentConnection class. Use the derived class to push content to clients.
C. Use the SignalR jQuery library in a web page to send messages to the hub and display updates from the hub.
D. Map a SignalR hub to the app builder pipeline by using an OWIN startup class.
E. Start the SignalR hub asynchronously and respond to the appropriate callback methods.
Answer: ACD
Explanation:
A:
In Solution Explorer, right-click the project, select Add | New Folder, and add a new folder named Hubs. Right-click the Hubs folder, click Add | New Item, select the Visual C# | Web | SignalR node in the Installed pane, select SignalR Hub Class (v2) from the center pane, and create a new hub named ChatHub.cs. You will use this class as a SignalR server hub that sends messages to all clients.
C:
Use the SignalR jQuery library in a web page to send messages and display updates from the hub.
D:
Create an OWIN startup class to configure the application.
NEW QUESTION 205
You are developing an ASP.NET MVC application. Devices that use many different browsers will use the application. You have the following requirements:
– Content must display correctly when a device is in landscape or portrait orientation.
– Content must not scale when the device orientation changes.
– Content must be displayed by using the maximum available screen space.
– The application must render properly in Internet Explorer 8 or later versions.
You need to configure the application. Which two actions should you perform? Each correct answer presents part of the solution.
A. Use JavaScript to evaluate the window.innerWidth and window.innerHeigh properties.
B. Set the value of the width property for the viewport meta tag to device-width.
C. Use CSS to target the HTML element on each page. Set the values of the width and height properties to 100%.
D. Use CSS media queries to target screen size, device orientation, and other browser capabilities.
Answer: BD
Explanation:
B:
If you want the viewport width to match the device’s physical pixels, you can specify the following:
For this to work correctly, you must not explicitly force elements to exceed that width (e.g., using a width attribute or CSS property), otherwise the browser will be forced to use a larger viewport regardless.
D:
Media queries in CSS3 extend the CSS2 media types idea: Instead of looking for a type of device, they look at the capability of the device. Media queries can be used to check many things, such as:
– width and height of the viewport
– width and height of the device
– orientation (is the tablet/phone in landscape or portrait mode) resolution
Using media queries are a popular technique for delivering a tailored style sheet to tablets, iPhone, and Androids.
