You have a SharePoint Server 2013 server farm.
You need to ensure that users can use the Newsfeed app on their My Site to aggregate user actions and
system activities.
Which type of cache should you configure?

A.
An output cache

B.
An object cache

C.
A BLOB cache

D.
A distributed cache

Explanation:
SharePoint 2013, makes use of distributed cache to cache newsfeeds, microblogging, conversations,
security trimming, OneNote client access, and even keeps the FedAuth cookie for claims based
authentication on the server side, so it’s more secure, load balancer friendly, and works with webkitbased browsers that like to chop off your cookies at 64kb.
