Hi all,

I am preparing for Platform App Builder certification and was looking into previous years real time scenario questions.

I have one question to ask that I have searched a lot but confused.

Can anyone provide a correct answer with valid explanation ?

Universal Containers needs a field on the Account to track how many Opportunities are closing within next 30 days.

What can be used to accomplish this goal?

A) Process Builder

b) Apex Code

c) Roll Up summary field

d) Workflow Rule

Many Thanks !!
