You have a SharePoint Server 2013 server farm.
You implement Business Connectivity Services (BCS). You need to ensure that the BCS data is available for
search.
What should you configure?

A.
A result source

B.
A content source

C.
A search scope

D.
A crawl rule

Explanation:
A content source is a set of options that you use to specify what, when, and how to crawl. When a Search
service application is created, a content source named “Local SharePoint sites” is automatically created and
configured for crawling all SharePoint sites in the local server farm. You can create additional content sources
to specify other content to crawl and how the system should crawl that content. After you create a content
source, you can edit or delete it at any time.
