Question-23: You have been employed at QuickTechie Inc. for the last seven years, and only recently you received training to become a Google Cloud Solution Architect. Now, the company has tasked you with the responsibility of deploying an application to Google Cloud. The application is an integrated component of the system. It is necessary for the application running on Google Cloud to be able to interact with apps running in environments that do not use Google Cloud. The throughput that should be anticipated on average is 256 kbps. The company demands system availability that is as near to 100 percent as is humanly achievable. cost optimization In order to satisfy the needs of the company, you will need to design the connection between the different sites. What should your preparations consist of?
A. An HA Cloud VPN gateway connected with two tunnels to an on-premises VPN gateway
B. Connecting two on-premises VPN gates to two Classic Cloud VPN gateways Set up each Classic Cloud VPN gateway such that it has two separate tunnels, each of which connects to a distinct set of on-premises VPN gateways.
C. Two HA Cloud VPN gateways connected to two on-premises VPN gateways Configure each HA Cloud VPN gateway to have two tunnels, each connected to different on-premises VPN gateways
D. A single VPN gateway located in the cloud that is linked to a gateway located on-premises.

: 1 Explanation: If the on-premises gateway, also known as a peer, has not one but two distinct external P addresses. The high availability virtual private network gateway utilises two tunnels, one tunnel to each external IP address on the peer device. This configuration, which is described in option 3, is a comprehensive solution that offers full redundancy of the on-premises gateway. Since the online documentation only describes using a single HA VPN Gateway, this is likely to be the more expensive option, and having two HA VPN Gateways is an unusual configuration. The correct answer is option 1, so you should choose that. When set up with two different interfaces and two different external IP addresses, a High Availability VPN (HA VPN) can guarantee a service availability of 99.99%. It is necessary to have a tunnel connecting each of the two interfaces on the HA VPN gateway to the corresponding interfaces on the peer gateway in order to fulfil the 99.99% service level agreement on the Google Cloud side. Option 1 is also capable of providing availability of 99.99%, and there is no requirement for C, which will incur additional costs.
