There is a question: How do I set up dynamic routing for Prisma SD-WAN?

Which of the following two answers is more relevant to the question? and why?

Answer A: Configure Dynamic Routing You can configure dynamic routing using BGP 
for a branch or data center. The configuration on a branch ION device is
 identical to a data center ION device with the exception of prefix 
advertisement in a branch and additional core and edge peers in a data 
center. This configuration is for a branch ION device. Note the 
differences in configuration between a branch ION device and a data 
center ION device in the relevant sections. Use the following steps to 
configure dynamic routing using BGP: Enable layer 3 forwarding.
