Google Cloud Professional Cloud Network Engineer — Question 159

You are responsible for designing a new connectivity solution between your organization's on-premises data center and your Google Cloud Virtual Private Cloud (VPC) network. Currently, there is no end-to-end connectivity. You must ensure a service level agreement (SLA) of 99.99% availability. What should you do?

Answer options

• A. Use one Dedicated Interconnect connection in a single metropolitan area. Configure one Cloud Router and enable global routing in the VPC.
• B. Use a Direct Peering connection between your on-premises data center and Google Cloud. Configure Classic VPN with two tunnels and one Cloud Router.
• C. Use two Dedicated Interconnect connections in a single metropolitan area. Configure one Cloud Router and enable global routing in the VPC.
• D. Use HA VPN. Configure one tunnel from each interface of the VPN gateway to connect to the corresponding interfaces on the peer gateway on-premises. Configure one Cloud Router and enable global routing in the VPC.

Correct answer: D

Explanation

The correct answer is D, as using HA VPN allows for redundancy with two tunnels, which is essential for achieving a high SLA of 99.99% availability. Options A and C do not provide sufficient redundancy, and option B, while it establishes a connection, does not meet the high availability requirement as effectively as HA VPN does.
