Q 1 - You are designing an application in which a section of the main page will be populated by content from a third-party provider. You do not have control over the responsiveness of the client or how much information will be returned with each request. The call is to a Restful service and will return the information formatted in Extensible Markup Language (XML). What is the best way to implement this application?

A - Design a model that handles the data call to populate the model. Create a partial view containing only this display area and put an asynchronous service call that returns this model in the partial view controller.

B - Put a synchronous service call into the main page controller.

C - Create a partial view containing only this display area and put a synchronous service call in the partial view controller.

D - Create a partial view containing only this display area and put an asynchronous service call in the partial view controller.

E - A and D both

F - All of the above

Answer : A

Explanation

A.Because you do not have control over the responsiveness of the third- party provider and you do not know how much data might be returned from each call, you should wrap the call in the asynchronous framework. Providing the data in a strongly-typed model gives it more flexibility than working with the raw XML on the client side.

Q 2 - In an HTTP module, can you redirect the request to a different handler than is in the routing table? If so, what event would you handle?

A - Yes and you handle the PostAuthorizeRequest event.

B - No, after the request starts into the process, it either continues through to the mapped handler or throws an error.

C - Yes and you handle the MapRequestHandler event.

D - Yes and you handle the ReleaseRequestState event.

E - A and D both

F - All of the above

Answer : C

Explanation

C.You handle the mapping of the request in the MapRequestHandler.

Q 3 - In which of the following scenarios should you include validation? (Choose all that apply.)

A - You have an online diary with two form fields, a title, and a large subject box. A title is not required, and the subject content is stored in a database column with no maximum size.

B - The web application you maintain has an area that serves as a pass-through to another company's web services. The form contains personal information, such as address and phone number, and is used to set up a profile on the company's retirement partner website. The partner has never given you any instructions as to what is or is not required to be sent to them.

C - Your application is a long wizard that college students use to apply for financial aid. They do not have access to the application until they are already logged on to the system so the application knows who they are. Most students will log on many times to finish the application, so any field might or might not be completed at any time.

D - You are developing a simple form that helps home brewers keep track of their process. The form provides two input fields: Date/time and ph level. The Date/ time box needs to be an ordinary text box because people around the world might enter the date differently, in a way that is meaningful to them. The ph level can be either a numeric value or a text description.

E - C and A both

F - All of the above

Answer : F

Explanation

F.You should build in validation to check that at least one field has been populated before saving an entry.Although the partner company has not provided any requirements, your company is responsible for data entry and therefore should ensure that the data passing through the application meets some minimum criteria.The application has many entry fields so it is difficult to predict when an entry hits a valid stage. However, you already know you have constraints on the data being input because of the size of the database columns in which you will be storing them. A MaxLength validator on each field would help ensure that there is no loss of data.Although either field in the form can be anything, they should have a maximum length limit imposed so the data does not exceed the size of the database column they will be stored in. You should also validate that neither field is empty.

Q 4 - You are modifying an ASP.NET MVC web application for a client. The client requires that the application must be viewable on Android devices in a UI format native to the device. What should you do? (Choose all that apply.)

A - Run the Install-Package jQuery.Mobile.MVC command using the Package Manager console.

B - Create a viewport and use @media queries to make styles that are specific for Android.

C - Create corresponding mobile views for the project targeted toward Android.

D - Modify the Web.config file in Shared views in the project to add in support for other browsers.

E - C and B both

F - All of the above

Answer : C

Explanation

C. Text revealed by mouse-overs not being picked up by search engine crawlers indicates that content is being skipped

Q 5 - You have been tasked with modernizing an application created in ASP 3.0. Part of one of the pages contains HTML that comes as a string from a third-party application as part of a service call that populates part of a form. The same form contains input values for your application. You need to support the same business process as the original application, but you also want to use some MVC features. What is the approach?

A - Create a single model containing information from your local application. Use strongly-typed binding as much as possible and manually match the rest of the fields.

B - Create a single model for the local input fields and the service call input, and use ToValueProvider to map the entire object.

C - Create a single model. Use weakly-typed binding for the form fields, and the HTML provided by the third-party application.

D - Create a model that contains only your fields and strongly bind the fields to the model. Create a second model that maps to the fields in the imported HTML and bind to that model using ToValueProvider.

E - C and C both

F - All of the above

Answer : D

Explanation

D.The key is separating your data input fields from the provided input fields. You can strongly-bind to yours because you have full control over the relationship between your model and your view, and can then use the ToValueProvider to merge the other model that is tied to the provided input fields.

Q 6 - Your application has an intermittent issue, based on the user's path through the application, in which the application seems to stop running. Even when running in debug mode, the application calls a web service and then stops. The application locks and the call never returns, thus the user's request is never completed and eventually times out. What performance or profiling tool will provide the most pertinent information about your application?

A - CPU sampling in the Performance Wizard

B - Memory allocation in the Performance Wizard

C - Resource contention data in the Performance Wizard

D - Tracing from the System.Diagnostics namespace that logs the times of web service call and web service return

E - The Health Monitoring tool, for capturing security information related to the interaction with the web service

F - A and D both

Answer : C

Explanation

C.Thread and resource profiling will give some understanding of what kind of actions are taking place that will cause a resource or thread to be blocked

Q 7 - You will be deploying your application in Windows Azure. You know that you need to include logging, but you have some concerns. What diagnostic capabilities can Windows Azure support? (Choose all that apply.)

A - The capability to turn on and off different aspects of the Windows Azure diagnostics through configuration changes

B - The capability to retain logs from your custom logging solution on a Windows Azure storage account

C - The capability to retain logs from your custom logging solution when written to a local store

D - The capability to send entries to the Windows Azure diagnostics system from within your application

E - A , B and D

F - All of the above

Answer : E

Explanation

E.You can control the diagnostics setting through configuration within your Windows Azure–hosted application.Although the Windows Azure VMs get recycled when the role restarts, saving the logs to the Windows Azure storage system outside of your VM would ensure that they are available.You can treat the Windows Azure diagnostics system like a traditional logging tool by writing messages to the system.

Q 8 - Why should you create a custom role provider? (Choose all that apply.)

A - To use a data source not regularly supported

B - To use the SimpleRoleProvider

C - To use a database design different than .NET provides

D - To provide a special configuration file entry

E - B and C both

F - All of the above

Answer : E

Explanation

E.Because traditional providers work only on SQL Server, accessing a differ- ent data provider such as MySQL would require a custom provider.Using a different database design would require that you create a custom provider.

Q 9 - What are the primary differences between the AntiXSS Library and the default .NET Framework? (Choose all that apply.)

A - The AntiXSS Library takes a blocked-list approach, whereas the .NET Framework takes an accepted-list approach.

B - The AntiXSS Library has be modified to realize performance gains.

C - The AntiXSS Library takes an accepted-list approach, whereas the .NET Framework takes a blocked-list approach.

D - The AntiXSS Library offers enhanced globalization capabilities.

E - B ,C and D

F - All of the above

Answer : E

Explanation

E.The AntiXSS Library is more performant than the traditional .NET Framework.AntiXSS takes an accepted-list approach, which means only those characters that have been approved are allowed through.AntiXSS was designed to allow additional support for globalization.
