Q71. HOTSPOT – (Topic 4)
You are developing an ASP.NET MVC web application that enables users to open Microsoft Excel files.
The current implementation of the ExcelResult class is as follows.
You need to enable users to open Excel files. You have the following code:
Which code segments should you include in Target 1, Target 2 and Target 3 to implement the ExecuteResult method? To answer, select the appropriate option or options in the answer area.
Q72. HOTSPOT – (Topic 4)
You are developing an ASP.NET MVC application that authenticates a user by using claims-based authentication.
The application must:
. Use Windows Identity Foundation 4.5.
. Support the Windows Azure Access Control Service.
You need to implement authentication.
How should you build the class constructor? (To answer, select the appropriate option from the drop-down list in the answer area.)
Q73. – (Topic 4)
You are developing an ASP.NET MVC application that uses forms authentication. The application uses SQL queries that display customer order data.
You need to prevent all SQL injection attacks against the application.
How should you secure the queries?
A. Implement parameterization.
B. Pattern check the input.
C. Filter out prohibited words in the input.
D. Escape single quotes on string-based input parameters.
Explanation: With most development platforms, parameterized statements that work with parameters can be used (sometimes called placeholders or bind variables) instead of embedding user input in the statement. A placeholder can only store a value of the given type and not an arbitrary SQL fragment. Hence the SQL injection would simply be treated as a strange (and probably invalid) parameter value.
Q74. – (Topic 3)
Customers download videos by using HTTP clients that support various content encodings. You need to configure caching on the DownloadVideo action to maximize performance.
Which attribute should you add?
A. Option A
B. Option B
C. Option C
D. Option D
E. Option E
Q75. – (Topic 4)
You are developing an ASP.NET MVC application.
You need to authenticate clients by using an ASP.NET membership database.
Which authentication method should you implement?
Q76. – (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.
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.

Q77. – (Topic 4)
You are developing an ASP.NET MVC application that will be deployed to servers on multiple networks.
The application must be compatible with multiple browsers. You must track the page number that the user is viewing in search results.
You need to program the location for storing state information.
Where should you persist state information?
Q78. – (Topic 4)
You are developing an ASP.NET MVC application that will run on Azure.
The application uses Event Tracing for Windows (ETW) for logging operations.
You need to retrieve the ETW data for the application from a deployed Azure instance by using the Azure Diagnostics API.
Which data source should you use?
A. Azure Diagnostic infrastructure logs
B. Windows event logs
C. performance counters
D. .NET EventSource
Explanation: Azure Diagnostics 1.2 and 1.3 are Azure extensions that enable you to
collect diagnostic telemetry data from a worker role, web role, or virtual machine running in
Diagnostics 1.2 and 1.3 enable the collection of ETW and .NET EventSource events.
<Event id="1" eventDestination="EnumsTable"/>
<Event id="2" eventDestination="MessageTable"/>
<Event id="3" eventDestination="SetOtherTable"/>
<Event id="4" eventDestination="HighFreqTable"/>
<DefaultEvents eventDestination="DefaultTable" />
