Keung (@K_C) ,
To answer your basic question, you get to use your own evaluation of which CBK domains apply for those study and course efforts. To do that, it is essential that you read and understand both the CBK domain descriptions for your certification and the (ISC)2 CPE Handbook. Claim one CPE unit for each hour of course, and make a reasonable claim for time on self-study. If there is a published book you studied, I suggest claiming the book for the CPE by writing the required short book report.
Be sure to check the (ISC)2 web site occasionally to ensure you have the current CPE Handbook. The guidance changes about once a year.
As for @Shannon's tip to read the other thread, you have to read the entire long thread to get the correct advice: DO NOT waste your time asking (ISC)2 staff for advice before submitting your CPE claims. Deep into the thread William @denbesten properly showed that Shannon's initial reply there to ask (ISC)2 was not the best advice.
The lesson for me:
Follow Admiral Grace Hopper's maxim,
"It's better to beg forgiveness [deal with an audit] than ask for permission."
Good luck,
