Which action should you perform?

You create Microsoft Windows-based applications. You participate in the planning phase of an incident tracking tool for technical support analysts.

The incident tracking tool must meet the following requirements:

Technical support analysts must open multiple incidents simultaneously.
The application can run only one instance at a time.
Users must be able to adjust the order and layout of the incident screens.

You need to design an application user interface that meets these requirements with the minimum amount of code. Which action should you perform?

Which rationale should you choose?

You create Web-based client applications. You are evaluating an application. The application displays data that is stored in XML files. The data changes periodically. The development team implements a complex caching solution to improve the performance of the application. However, the caching solution is identified as causing the performance of the application to drop to an unacceptable level. The caching solution also results in significant data latency. The application requirements state that the data that is displayed in the application must be close to real time. You need to ensure that the application design meets the requirements. You also need to ensure that least amount of code is used. Which rationale should you choose?

Which action should you perform to achieve this goal?

You create Microsoft Windows-based applications. You are designing a reusable composite control for a customer service application. The composite control contains three TextBox controls.

What should you recommend?

You create Web-based client applications. You review an application that manages the medical information of patients. The information is confidential and needs to be stored by using the most secure method available.
The application encrypts patient data and stores it in database tables. The application stores a document or image that is related to a patient in the following manner:

The name of the item is stored in the database.
The physical document or image is stored in the local file system.

The application locates and retrieves the physical document or image based on the name that is returned from the database when the data for a patient is queried. You need to evaluate whether the current application design uses the most secure method available to store information and provide an appropriate recommendation. What should you recommend?

What should you do?

You have an external line of business application. The LOB application data is exposed to a web service. You plan to use the BDC catalog to access the LOB application. You create the following type descriptor for the data row in the BDC application file:

<TypeDescriptor TypeName=”System.String” Name=”LastName” />

You attempt to import the application definition file to the BDC and receive the following error:

“Could not create profile page for entity filtered contact. The error is profile page creation for the entity filtered contact skipped. Entity filtered contact has no identifiers defined in the specific finder view.”

You need to ensure that you can import the application definition file to the BDC.
