You need to choose the appropriate data access strategy for the college textbook area of the web application.
Which data access technology should you implement?
You are developing an ASP.NET Core web application by using an Entity Framework code-first approach.
The application uses a SQLite database.
You make changes to the classes in the model. You must apply the changes to the database.
You need to suggest an approach to reliably handle the Entity Framework migrations.
Which three actions should you perform? Each correct answer presents a part of the solution.
NOTE: Each correct selection is worth one point.
You are developing a WCF service. The service will stream messages to clients on the internal network.
You must use Windows Authentication, and all messages must be binary encoded.
You need to configure the service.
What should you do? (To answer, drag the appropriate elements to the correct location or locations in the
answer area. Each element may be used once, more than once, or not at all. You may need to drag the split bar
between panes or scroll to view content.)
The GetVendors() action in the ProcessedOrderController controller is querying the database each time it is
run. The GetVendors() action must query the database only if the cache is null.
You need to add code to the action at line PC33 to cache the data.
Which code segment can you use? (Each correct answer presents a complete solution. Choose all that apply.)
You are developing an application that reads and writes data from a SQL Server database.
You need to ensure transactional data integrity.
Which isolation level should you use?
