Practice Test 3 | Google Cloud Certified Professional Cloud Network Engineer | Dumps | Mock Test
As the network engineer for a firm considering using Cloud VPN for connectivity between GCP and its on-premises network. The on-premises VPN gateway supports GRE protocol for tunnelling and does not support dynamic routing.

B. Yes, because the on-premises gateway does not support IPsec, which Cloud VPN uses
