Select 2Your organization is deploying a critical Oracle Database@Azure solution for an OLTP workload and setting up a Data Guard standby environment in Oracle Cloud Infrastructure (OCI). You require a secure, low-latency connection between Azure and OCI for Data Guard replication. Which two steps are recommended to establish a resilient cross-cloud link for your database replication?
- A
Establish a dedicated ExpressRoute circuit in Azure and link it to Oracle Cloud Infrastructure FastConnect.
- B
Use a site-to-site VPN from the Azure VNet to the OCI Virtual Cloud Network (VCN).
- C
Directly peer the Azure VNet with the OCI VCN over the public internet.
- D
Leverage the integrated Azure-OCI Interconnect offering to create private, low-latency connectivity.
Show answer and explanation
Correct answers: A, D
Explanation
For mission-critical Oracle Database deployments spanning Azure and OCI, high-throughput private connectivity is crucial for maintaining database replication with minimal latency. The recommended architecture leverages the combined strengths of Azure ExpressRoute and OCI FastConnect, often referred to as the official Azure-OCI Interconnect, to provide a dedicated, private network path. For more information, consult Oracle and Microsoft documentation on cross-cloud connectivity best practices for Oracle Database@Azure.
- A. Correct.
Option 1 is correct. Creating a dedicated ExpressRoute circuit in Azure and connecting it to OCI FastConnect is a recommended approach to achieve high-bandwidth, low-latency private connectivity between the two clouds. This directly supports production-grade replication needs for Data Guard.
- B. Incorrect.
Option 2 is incorrect. While a VPN tunnel can be a fallback method, it typically does not provide the same performance, throughput, or SLA guarantees as the ExpressRoute-FastConnect integration. It may be used for dev/test or lower-tier workloads, but it isn�t the recommended solution for mission-critical Data Guard replication.
- C. Incorrect.
Option 3 is incorrect. Directly peering the Azure VNet with the OCI VCN over the public internet is not supported. Even if it were, routing sensitive replication traffic over the public internet would introduce potential security and latency issues, making this an unsuitable approach for production workloads.
- D. Correct.
Option 4 is correct. The Azure-OCI Interconnect offering combines Azure ExpressRoute and OCI FastConnect into an integrated solution that delivers high performance and secure, private data transfer. This simplifies cross-cloud deployment and is ideal for Oracle Database replication scenarios.
