Answer: BE

Explanation:

In a Meraki Auto VPN setup, peers interact using the following ports:

Peers contact the VPN registry at UDP port 9350.

The VPN registry is a Meraki cloud service that helps with the establishment of VPN tunnels between Meraki devices. Peers use UDP port 9350 to communicate with this service.

For IPsec tunneling, peers use UDP ports 500 and 4500.

These ports are standard for IPsec VPNs. Port 500 is used for the initial key exchange and negotiation, while port 4500 is used for NAT traversal.
