On-Premises Orchestrator Multi-node installation

Hello,

I have been assigned to install UiPath Orchestrator On-premises using a multinode configuration

I am using the UiPathPlatformInstaller.exe version 2020.04.

I would really appreciate if someone could answer the below questions:

  1. Should I use application pool identity or do i need to create a custom account?

  2. The public orchestrator URL should be of the master node or the primary node?

  3. is it advisable to use the platforminstaller.exe or should i only use Orchestratorsetup.msi?

Thank you in advance
