Dear Sandeep,
First of all, congratulations on passing your exam!
As for the PMI-ACP exam, there is no correlation between the
PMBOK® Guide and the PMI-ACP exam. The PMI-ACP exam is not based on the
PMBOK® Guide. Rather, it's based on the twelve books which have been selected by the PMI as the reference source to develop their PMI-ACP exam.
However, according to the information on the PMI website,
The Agile Practice Guide is planned to be released on Sep 6
th this year, and the exam will be updated subsequently in Q1 2018. You may want to check the PMI website for more details:
