Q1. An advertising campaign was recently launched. Some of the ads contain a link to products that no longer exist or have IDs that have changed.
You need to ensure that all product links display a product. Which code segment should you use to configure the route?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: A
Q2. You are developing an ASP.NET MVC news aggregation application that will be deployed to servers on multiple networks.
The application must be compatible with multiple browsers. A user can search the website for news articles. You must track the page number that the user is viewing in search results.
You need to program the location for storing state information about the user's search. What should you do?
A. Store search results and page index in Session.
B. Use Application state to store search terms and page index.
C. Use QueryString to store search terms and page index.
D. Store search results and page index in TempData
Answer: C
Q3. You are developing an ASP.NET MVC application. Devices that use many different browsers will use the application.
You have the following requirements:
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: B,D
Explanation:
B: If you want the viewport width to match the deviceu2021s physical pixels, you can specify the following:
<meta name="viewport" content="width=device-width">
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.

Q4. You are designing an enterprise-level Windows Communication Foundation (WCF) application. User accounts will migrate from the existing system. The new system must be able to scale to accommodate the increasing load.
You need to ensure that the application can handle large-scale role changes.
What should you use for authorization? (Each correct answer presents a complete solution. Choose all that apply.)
A. Resource-based trusted subsystem model
B. Identity-based approach
C. Role-based approach
D. Resource-based impersonation/delegation model
Answer: B,C
Explanation:
Advanced Maturity: Authorization as a Service
In the advanced level of maturity for authorization, role storage and management is consolidated and authorization itself is a service available to any solution that is service- enabled.
* The Trusted Subsystems Model
Once authorization is available as an autonomous service, the need for impersonation is eliminated. Instead of assuming the identity of the user, the application uses its own credentials to access services and resources, but it captures the user's identity and passes it as a parameter (or token) to be used for authorization when a request is made. This model is referred to as the trusted subsystem model, because the application acts as a trusted subsystem within the security domain.
Q5. You are developing a controller for an ASP.NET MVC application that manages blog postings.
The security protection built in to ASP.NET is preventing users from saving their HTML. You need to enable users to edit and save their HTML while maintaining existing security
protection measures.
Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
Explanation:
Example: ValidateInput at Action Method Level
The user can submit Html for this action method successfully with the following code.
public class HomeController : Controller
{
public ActionResult AddArticle()
{
return View();
}
[ValidateInput(false)] [HttpPost]
public ActionResult AddArticle(BlogModel blog)
{
if (ModelState.IsValid)
{
}
return View();
}
}

A. If (Request.IsTabletDevice)
B. If (Request.Browser.IsBrowser("Mobile"))
C. If (Request.UserAgent["Tablet"])
D. If (Request.Browser.IsMobileDevice)
Answer: D
Q7. You need to ensure that developers can connect to a Microsoft Azure role by using RDP.
What should you do?
A. Export a certificate with a private key. Upload the .pfx file to the Certificates section under the TranscodeWorkerRole hosted service on the Azure Management Portal.
B. Export a certificate with a private key. Upload the .pfx file to the Management Certificates section on the Azure Management Portal.
C. Export a certificate without a private key. Upload the .cer file to the Management Certificates section on the Azure Management Portal.
D. Export a certificate without a private key. Upload the .cer file to the Certificates section under the TranscodeWorkerRole hosted service on the Azure Management Portal.
Answer: A
Explanation: In case you donu2021t want to use the RDP certificate created by Windows Azure Tools and want to use a custom certificate instead, the following steps will guide you. These steps can also be used in case package is not being published from Visual Studio rather it is being built locally, saved in either Local Machine's Drive or Windows Azure Blob Storage and subsequently published from there.
Here are the steps which are required to get pass the publishing error which you might be running into. You would need to upload the Certificate with Private Key to the portal (when Visual Studio is used this is done in the background).
Detailed steps.
1. In Visual Studio, go to the solution which is being developed.
2. Right click the Web Project -> Configure Remote Desktop -> click on View to see Certificate details (Since I donu2021t have a custom certificate I will use one create by Windows Azure Tools itself)
3. Go to Details tab on Certificate -> Click Copy to file.. -> Next -> Select u2021Yes, export the private keyu2021 -> Next -> Continue with default setting and create a password when asked (please refer below screenshots)
4. These steps will generate a .PFX file for this certificate. Now we need to upload this certificate to the portal (for the respective cloud service)
5. Go to the Azure Management Portal -> Go to the Cloud Service in question -> Certificates Tab -> Upload the newly created certificate (.PFX file)
Note:
* The certificates that you need for a remote desktop connection are different from the certificates that you use for other Azure operations. The remote access certificate must
have a private key.
* Microsoft Azure uses certificates in three ways:
/ Management certificates u2013 Stored at the subscription level, these certificates are used to enable the use of the SDK tools, the Windows Azure Tools for Microsoft Visual Studio, or the Service Management REST API Reference. These certificates are independent of any cloud service or deployment.
/ Service certificates u2013 Stored at the cloud service level, these certificates are used by your deployed services.
/ SSH Keys u2013 Stored on the Linux virtual machine, SSH keys are used to authenticate remote connections to the virtual machine.

Q8. You are developing an ASP.NET MVC application. The application includes the following method- Une numbers are included for reference only.
The application calls the Generate Message method before displaying each page. The Generate Message method throws NullReferenceException exceptions. You need to use Code Contracts to prevent the exceptions. Which code segment should you insert at line 03?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: B

B. Create an HttpHandler to check for a valid HTTP header value in the ProcessRequest method.
C. Create an HttpModule and check for a valid HTTP header value in the AuthenticateRequest event.
