Which out of the box Salesforce B2B Commerce page can give instructions to web crawlers from accessing specific Salesforce B2B Commerce pages?
A . CCCat?SiteMap
B . cc_RobotsTxT
C . CCSiteIndex
D . CCPage

Answer: B

Explanation:

The out of the box Salesforce B2B Commerce page that can give instructions to web crawlers from accessing specific Salesforce B2B Commerce pages is cc_RobotsTxt. This is a Visualforce page that generates a robots.txt file, which is a text file that tells web crawlers which pages or files they can or can’t request from a site. The page uses the configuration settings CO.RobotsTxtAllow and CO.RobotsTxtDisallow to specify which paths are allowed or disallowed for web crawlers. For example, User-agent: * Disallow: /CCCart will instruct web crawlers to not access the CCCart page.
