Q41. HOTSPOT – (Topic 4) 

You are developing an ASP.NET MVC application. The application includes the following code. Line numbers are included for reference only.

For each of the following statements, select Yes if the statement is true. Otherwise, select No.

Q42. – (Topic 3)

Q43. – (Topic 4) 

You are designing a localized ASP.NET MVC online shopping application that will be deployed to customers in the United States, China, France, and Brazil. The application must support multiple cultures so that content in the appropriate language is available in each area. 

You need to ensure that the content can be viewed in several languages. 

How should you implement this feature? 

A. Use a resource (.resx) file to provide translations. 

B. Use Systems.Collections.Generics.Dictionary to store alternative translations. 

C. Ensure that all strings are marked internal to avoid conflict with internal literals. 

D. Include language-specific content in the assembly manifest and use .NET culture libraries. 

Answer:

Explanation: A resource file is an XML file that contains the strings that you want to translate into different languages or paths to images. The resource file contains key/value pairs. Each pair is an individual resource. Key names are not case sensitive. For example, a resource file might contain a resource with the key Button1 and the value Submit. You create a separate resource file for each language (for example, English and French) or for a language and culture (for example English [U.K.], English [U.S.]). Each localized resource file has the same key/value pairs; the only difference is that a localized resource file can contain fewer resources than the default resource file. The built-in language fallback process then handles loading the neutral or default resource.

Topic 3, Video Transcoding Service 

Background 

You are developing a video transcoding service. This service is used by customers to upload video files, convert video to other formats, and view the converted files. This service is used by customers all over the world. 

Business Requirements 

The user-facing portion of the application is an ASP.NET MVC application. It provides an interface for administrators to upload video and schedule transcoding. It also enables administrators and users to download the transcoded videos. 

When videos are uploaded, they are populated with metadata used to identify the video. The video metadata is gathered by only one system when the video upload is complete. 

Customers require support for Microsoft Internet Explorer 7 and later. 

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. 

Technical Requirements 

User Experience: 

The front-end web application enables a user to view a list of videos. 

The main view of the application is the web page that displays the list of videos. 

HTML elements other than the list of videos are changed with every request 

requiring the page to reload. 

Compatibility: 

Some customers use browsers that do not support the HTTP DELETE verb. 

These browsers send a POST request with an HTTP header of X-Delete when the intended action is to delete. 

Transcoding: 

The video transcoding occurs on a set of Windows Azure worker roles. The transcoding is performed by a third-party command line tool named transcode.exe. When the tool is installed, an Environment variable named transcode contains the path to the utility. A variable named license contains the license key. The license for the transcoding utility requires that it be unregistered when it is not in use. The transcoding utility requires a significant amount of resources. A maximum of 10 instances of the utility can be running at any one time. If an instance of the role cannot process an additional video, it must not prevent any other roles from processing that video. 

. The utility logs errors to a Logs directory under the utilities path. 

. A local Azure directory resource named perf is used to capture performance data. 

Development: 

. Developers must use Microsoft Remote Desktop Protocol (RDP) to view errors generated by the transcode.exe utility. 

. An x509 certificate has been created and distributed to the developers for this purpose. 

. Developers must be able to use only RDP and not any other administrative functions. 

Application Structure 

Q46. – (Topic 4) 

You are developing a new ASP.NET MVC application that will be hosted on Microsoft Azure. You need to implement caching. 

The caching solution must support the following: 

The cache must be able to store out-of-process ASP.NET session state. 

The cache must be able to store a variety of data types. 

The cache must offer a large amount of space for cached content. 

You must be able to share output cache content across web server instances. 

You need to select a cache solution. 

Which caching solution should you choose? 

A. ASP.NET Caching 

B. Azure In-Role Cache 

C. Azure Redis Cache 

D. Azure Managed Cache Service

Q47. HOTSPOT – (Topic 3) 

The designer for the website gave you the following image as the design for the page. 

The normal color for the tab is *2da4c2, and the color when the mouse is over the tab is #ffd800. 

The HTML that implements the navigation tab is as follows. 

You need to implement the design. 

What should you do? (To answer, select the appropriate options in the answer area.) 

Answer: 

Q48. – (Topic 4) 

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. 

Q49. – (Topic 4) 

You are developing an ASP.NET MVC web application for viewing a list of contacts. The application is designed for devices that support changes in orientation, such as tablets and smartphones. The application displays a grid of contact tiles in portrait mode. 

When the orientation changes to landscape, each tile in the grid expands to include each contact's details. The HTML that creates the tiled interface resembles the following markup. 

The CSS used to style the tiles in landscape mode is as follows. 

If this CSS is omitted, the existing CSS displays the tiles in portrait mode. 

You need to update the landscape-mode CSS to apply only to screens with a width greater than or equal to 500 pixels. 

Which code segment should you use? 

A. @media screen and (width >= 500px) { … } 

B. @media screen and (min-width: 500px) { … } 

C. @media screen(min-width: 500px, max-width: 1000px) { … } 

D. @media resolution(min-width: 500px) { … }
