QUESTION 4

You must filter the data on the SQL server before it is returned to the application server.
You need to return books checked out more recently than the entered date.
Which code segment should you use?

lead4pass 70-487 exam question q4-1

A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: A
The difference is that IQueryable is the interface that allows LINQ-to-SQL (LINQ.-to- anything really) to work. So if you
further refine your query on an IQueryable, that query will be executed in the database, if possible. For the IEnumerable
case, it will be LINQ-to-object, meaning that all objects matching the original query will have to be loaded into memory
from the database.

 

QUESTION 5
You need to build the connection from ReportApp to read the search data. The solution must minimize development
effort.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions
