Developing Microsoft Azure and Web Services — Question 48

You need to choose the appropriate data access technology for the cookbook area of the web application.
Which data access technology should you choose?

Answer options

• A. WCF Data Services
• B. LINQ to SQL
• C. ADO.NET
• D. Entity Framework

Correct answer: A

Explanation

WCF Data Services is the correct choice because it provides a way to expose and consume data over the web using OData, making it ideal for web applications. The other options, while capable of data access, are more suited for different contexts, such as local data access (LINQ to SQL, ADO.NET) or ORM scenarios (Entity Framework).
