Google Cloud Professional Cloud Architect — Question 5

You need to develop procedures to verify resilience of disaster recovery for remote recovery using GCP. Your production environment is hosted on-premises. You need to establish a secure, redundant connection between your on-premises network and the GCP network.
What should you do?

Answer options

• A. Verify that Dedicated Interconnect can replicate files to GCP. Verify that direct peering can establish a secure connection between your networks if Dedicated Interconnect fails.
• B. Verify that Dedicated Interconnect can replicate files to GCP. Verify that Cloud VPN can establish a secure connection between your networks if Dedicated Interconnect fails.
• C. Verify that the Transfer Appliance can replicate files to GCP. Verify that direct peering can establish a secure connection between your networks if the Transfer Appliance fails.
• D. Verify that the Transfer Appliance can replicate files to GCP. Verify that Cloud VPN can establish a secure connection between your networks if the Transfer Appliance fails.

Correct answer: B

Explanation

Option B is correct because it mentions both Dedicated Interconnect for file replication and Cloud VPN as a backup method for establishing a secure connection, ensuring redundancy. Option A incorrectly suggests direct peering, which does not provide the same level of security as Cloud VPN. Options C and D discuss the Transfer Appliance, which is not suitable for this scenario as it doesn't provide continuous connectivity like Dedicated Interconnect and Cloud VPN.
