Is PHP-FPM installed for wordpress-redis ee built?

What is the difference between nginx-wpfc easyengine build vs nginx-redis option while creating a new wordpress installation?

Can’t we use both PHP-FPM with redis support ? or does EasyEngine enables fastcgi support when I choose the wpredis option too ?

Edit: Ok figured it. Redis also supports full-page caching so there is no need of FastCGI which is also a fullpage caching mechanism. Correct me if I am wrong.
