Thanks for info shrawans31530030.

Any other guide available ?
What all section should we focus on mostly for the exam ?
Can anyone share their experience here ?
There's a wide range of guides available for Campaign. Regarding architecture, many things are not in the documentation, mainly due to the fact that there's a huge quantity of possible combinations and models.
You can still go through the installation guide to know more: General architecture
