You are designing a distributed application. The application must store a small amount of insecure global
information that does not change frequently. You need to configure the application to meet the requirements.
Which server-side state management option should you use? (Each correct answer presents a complete
solution. Choose all that apply.)
A.
Application state
B.
Session state
C.
Database support
D.
Profile properties
Why the answer here is Session state?
Session state is used: when you are storing short-lived information that is specific to an individual session and security is an issue. Do not store large quantities of information in session state. Be aware that a session-state object will be created and maintained for the lifetime of every session in your application. In applications hosting many users, this can occupy significant server resources and affect scalability.
It can’t be applicationstate: Application state is not shared among multiple servers serving the same application, as in a Web farm, or among multiple worker processes serving the same application on the same server, as in a Web garden. Your application therefore cannot rely on application state containing the same data for application state across different servers or processes.
It can’t be profile properties or database support. So the only answer here that makes some sense: Session state (small amount…)
the test is for small amount of insecure data so why you going in another direction – Do not store large quantities of information in session state – exactly, so session state is ok and it doesn’t say how many users either so should be safe
The answer should be A and C. I have to disagree with someone_new as well as fsays.

Yes I agree
why would you use database for a small amount of insecure data
For scalability reasons.
It should only be option C. database support. as Application state is not for distributed environment.
should be only C. wrong answer
neither application state or session state is available in distributed environment
Distributed application doesn´t mean necessarily having a web farm. You can have a distributed application if your DB is in a server and your only IIS instance in another.
As far as I understand A y C should be the answers.
Should be A,C
A: because it says global information, so storing at 1 places and this places is in MEMORY.
C: because the stored information should be retrieved from DB and loaded somewhere in this case it’s Application state. if you don’t choose this option (C), where should the information come from?
Answer is A .Application state because they clearly specify the server side state management. it says global information .
This question is confusing and can mean different scenarios. The one thing is for sure – it makes absolutely no sense to duplicate data for each user.
According to this link, answer is A & C: http://www.utestking.com/free-lead2pass-70-486-pdf-and-vce-dumps-100-percent-pass-guarantee-21-30.html
I think the key to the application state answer is that the data is ‘not frequently changed’. In other words we don’t have to synchronise the data across the servers. Each server can load it’s own copy of the global data. As a user session switches across the servers, the same data will be presented to the user from any server. An example of such data might be todays weather summary.

NEW QUESTION 191
You are developing an ASP.NET application that allows users to download Microsoft Azure log files. You need to improve the performance of the application. What should you do?
A. Minify the content files.
B. Enable compression in IIS.
C. Bundle the content files into a single .tar file.
D. Host the image, JavaScript, and CSS files on a different server.
Answer: C
Explanation:
Bundling is a new feature in ASP.NET 4.5 that makes it easy to combine or bundle multiple files into a single file. You can create CSS, JavaScript and other bundles. Fewer files means fewer HTTP requests and that can improve first page load performance.

NEW QUESTION 197
You are developing an ASP.NET MVC application that will run in a shared environment. The application requests the user’s password, and then uses the password to sign data. You need to minimize the potential for the password to be discovered by other processes that run in the shared environment. What should you do?
A. Add the SecuritySafeCriticalAttribute attribute to the methods which process the password.
B. Store the password in a SecureString instance.
C. Encrypt the password on the web page, and decrypt the password in the MVC application.
D. Run the code that processes the password in its own AppDomain.
Answer: D
Explanation:
Application domains provide a unit of isolation for the common language runtime. They are created and run inside a process. Application domains are usually created by a runtime host, which is an application responsible for loading the runtime into a process and executing user code within an application domain. The runtime host creates a process and a default application domain, and runs managed code inside it. Runtime hosts include ASP.NET, Microsoft Internet Explorer, and the Windows shell. For most applications, you do not need to create your own application domain; the runtime host creates any necessary application domains for you. However, you can create and configure additional application domains if your application needs to isolate code or to use and unload DLLs.
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.
