Google Professional Cloud Network Engineer Exam - Topic 8 Question 63 Discussion

Your organization has a hub and spoke architecture with VPC Network Peering, and hybrid connectivity is centralized at the hub. The Cloud Router in the hub VPC is advertising subnet routes, but the on-premises router does not appear to be receiving any subnet routes from the VPC spokes. You need to resolve this issue. What should you do?
A) Create custom routes at the Cloud Router in the hub to advertise the subnets of the VPC spokes.
B) Create custom learned routes at the Cloud Router in the hub to advertise the subnets of the VPC spokes.
C) Create custom routes at the Cloud Router in the spokes to advertise the subnets of the VPC spokes.
D) Create a BGP route policy at the Cloud Router, and ensure the subnets of the VPC spokes are being announced towards the on-premises environment.

I'm a bit confused about whether the routes need to be created at the hub or the spokes. I feel like I need to double-check that.

D is the correct answer, no doubt. Although, I do wonder if the on-premises router is just playing a game of hide-and-seek with those subnet routes.
