1Z0-1151-25 Question 64
Select 3Your company has configured Oracle Interconnect for Azure to establish a secure, low-latency connection between an Oracle Autonomous Database in a private subnet on Oracle Cloud Infrastructure (OCI) and a set of Azure VMs in a private virtual network (VNet). However, the Azure VMs cannot currently communicate with the Autonomous Database. Which three actions must you verify or configure to ensure traffic flows properly across the Interconnect?
- A
Configure non-overlapping private IP address ranges between the OCI VCN and the Azure VNet.
- B
Create a route rule in the OCI private subnet route table to direct Azure-bound traffic to the Dynamic Routing Gateway (DRG).
- C
Enable a NAT Gateway on both OCI and Azure to handle private traffic across the Interconnect.
- D
Establish a BGP session between the OCI DRG and the Azure ExpressRoute circuit for dynamic route advertisement.
Show answer and explanation
Correct answers: A, B, D
Explanation
In an Oracle-Azure interconnect scenario, both sides must have non-overlapping private networks (to avoid routing conflicts) and define route rules for private traffic. On the OCI side, you direct Azure-bound traffic via the DRG. BGP must be established between OCI (DRG) and Azure (ExpressRoute) so that each side learns the other� private subnets. Refer to Oracle and Microsoft� joint documentation on 'Oracle Interconnect for Azure' for detailed configuration steps and best practices.
- A. Correct.
Correct. Overlapping IP address ranges often prevent proper routing because both clouds see the same IP space, causing conflicts in route advertisements.
- B. Correct.
Correct. You must explicitly direct traffic from the private subnet to the DRG for Azure� private IP ranges. Without the correct route rule in place, the packets will not reach the Interconnect.
- C. Incorrect.
Incorrect. A NAT Gateway is not typically used to route private traffic over the Oracle Interconnect for Azure. The interconnect uses private IP routing, and NAT is not required in this configuration.
- D. Correct.
Correct. Oracle Interconnect for Azure leverages BGP for automatically exchanging routes between OCI and Azure. Without BGP correctly established and peered, your networks will not learn each other� routes.
