Exam Professional Cloud Network Engineer topic 1 question 21 discussion

The correct anwser is C Option 1: Scale the on-premises VPN gateway https://cloud.google.com/network-connectivity/docs/vpn/concepts/classic-topologies#option-1

Answer is 100% C! There is practically no difference between C and D in terms of increasing the throughput. However, D does not work due to one info given in the statement. 'create a secondary VPN gateway in a DIFFERENT region'. The secondary VPN gateway should be in the same region as the first VPN gateway in order for this method to work.

NOT B because would not necessarily increase the available bandwidth as the tunnels would still be limited by the capacity of the single on-premises VPN gateway

B seems correct : One peer VPN device with one IP address This topology describes one HA VPN gateway that connects to one peer device that has one external IP address. The HA VPN gateway uses two tunnels, both tunnels to the single external IP address on the peer device. https://cloud.google.com/network-connectivity/docs/vpn/concepts/topologies#1-peer-1-address

Choose C. Explanation: Adding a second on-premises VPN gateway with a different public IP address can provide redundancy and potentially load balancing across the two on-premises gateways. Creating a second tunnel on the existing Cloud VPN gateway that forwards the same IP range to the new on-premises gateway allows you to distribute traffic across both on-premises gateways. If the goal is to increase bandwidth by load balancing traffic across two on-premises VPN gateways, this approach can be valid.

Definitely C

Option C is the only option that matches one of the Google Increased throughput and load balancing options (option 2), and it has to be in the same region https://cloud.google.com/network-connectivity/docs/vpn/concepts/classic-topologies#option-1

https://cloud.google.com/network-connectivity/docs/vpn/concepts/classic-topologies#option-1 .....based on this, answer is C

You want this in the same region, so the answer is C

B is correct as per https://cloud.google.com/network-connectivity/docs/vpn/concepts/classic-topologies#option-1

Option B is the correct choice. By creating two VPN tunnels, you can distribute traffic between the tunnels, effectively increasing the available bandwidth. This configuration is known as a "redundant VPN gateway" configuration, where both tunnels are active at the same time and traffic can flow through either of them.

Answer C: Just read the first sentence https://cloud.google.com/network-connectivity/docs/vpn/concepts/classic-topologies#option-1

C is the correct option. Option D says to create another Cloud VPN GW to a DIFFERENT region, so it's not an option here. Doc: https://cloud.google.com/network-connectivity/docs/vpn/concepts/classic-topologies#vpn-throughput

C: Set up a second on-premises VPN gateway device with a different external IP address. Create a second tunnel on your existing Cloud VPN gateway that forwards the same IP range, but pointing at the second on-premises gateway IP. Your Cloud VPN gateway automatically load balances between the configured tunnels. You can set up the VPN gateways to have multiple tunnels load balanced this way to increase the aggregate VPN connectivity throughput.

why not B? you can have 1 cloudVPN gw in HA setup and you can configure each tunnel individually to the same remote public peer. Tested in the LAB and working fine

C. Add a second on-premises VPN gateway with a different public IP address. Create a second tunnel on the existing Cloud VPN gateway that forwards the same IP range, but points at the new on-premises gateway IP.

The correct answer is C
