1Z0-997-25 Question 110
Select 2Your organization runs an application tier in Microsoft Azure and leverages Oracle Database@Azure for database services. You also have a set of Oracle Cloud Infrastructure (OCI) services that need to communicate privately with your Azure-based application. You decide to implement Oracle Interconnect for Azure. Which two actions must you take to properly establish private connectivity between OCI and Azure, so the application can access both Oracle Database@Azure and OCI resources with minimal latency?
- A
A. Provision a public subnet in OCI for all Oracle Database@Azure traffic to ensure it routes over the public internet.
- B
B. Enable BGP dynamic routing with non-overlapping IP address ranges and configure both ExpressRoute on the Azure side and FastConnect on the OCI side for the Oracle Interconnect for Azure.
- C
C. Set up a separate site-to-site VPN between the Azure VNet and OCI to handle database traffic independently from the Interconnect.
- D
D. Attach your OCI VCN to the Interconnect Gateway and peer it with the Azure VNet� ExpressRoute gateway, ensuring subnets hosting the application and database are correctly advertised.
Show answer and explanation
Correct answers: B, D
Explanation
To implement Oracle Interconnect for Azure and ensure private, low-latency connectivity between Azure-hosted workloads (including Oracle Database@Azure) and OCI resources, you need to configure both ExpressRoute in Azure and FastConnect in OCI, and then attach/peer the respective gateways. Per Oracle and Microsoft best practices, BGP dynamic routing should be enabled with non-overlapping IP segments to avoid conflicts. This setup provides secure, high-performance connectivity, eliminating the need for VPN tunnels or public internet routing. For more information, refer to the official Oracle and Microsoft documentation on configuring Oracle Interconnect for Azure.
- A. Incorrect.
Option A is incorrect. Routing over the public internet defeats the purpose of private, low-latency connectivity. Oracle Database@Azure traffic should remain on the private interconnect.
- B. Correct.
Option B is correct. Properly enabling BGP dynamic routing with non-overlapping address ranges and configuring ExpressRoute (Azure) and FastConnect (OCI) is fundamental to establishing the Oracle Interconnect for Azure. This ensures a secure, private path with minimal latency.
- C. Incorrect.
Option C is incorrect. Creating a separate site-to-site VPN is neither required nor recommended when using Oracle Interconnect for Azure. The native interconnect already provides the secure private connectivity you need without adding extra complexity.
- D. Correct.
Option D is correct. You must attach the OCI Virtual Cloud Network (VCN) to an Interconnect Gateway and peer it with the Azure VNet� ExpressRoute gateway. This configuration ensures that routes to the relevant subnets in Azure (hosting the application and Oracle Database@Azure) and in OCI are advertised correctly over the private connection.
