Google Cloud Professional Cloud Network Engineer — Question 70

You are in the early stages of planning a migration to GCP. You want to test the functionality of your hybrid cloud design before you start to implement it in production. The design includes services running on a Compute Engine Virtual Machine instance that need to communicate to on-premises servers using private
IP addresses. The on-premises servers have connectivity to the internet, but you have not yet established any Cloud Interconnect connections. You want to choose the lowest cost method of enabling connectivity between your instance and on-premises servers and complete the test in 24 hours.
Which connectivity method should you choose?

Answer options

• A. Cloud VPN
• B. 50-Mbps Partner VLAN attachment
• C. Dedicated Interconnect with a single VLAN attachment
• D. Dedicated Interconnect, but don't provision any VLAN attachments

Correct answer: A

Explanation

The correct answer is A, Cloud VPN, as it provides a cost-effective solution for establishing a secure connection over the internet without the need for dedicated hardware. Options B and C involve higher costs due to the requirement for physical infrastructure, and option D does not offer any connectivity, making it unsuitable for testing purposes.
