1Z0-1151-25 Question 73
Select 2Your company hosts microservices on Google Cloud and an Oracle Autonomous Database on OCI. To facilitate reliable, low-latency connectivity, you plan to implement Oracle Interconnect for Google Cloud. Which two actions must be performed so that your GCP-based microservices can successfully access the Oracle Autonomous Database over this Interconnect?
- A
Set up a Cloud Router in GCP, create a VLAN attachment for OCI, and configure BGP sessions with the Dynamic Routing Gateway (DRG).
- B
Enable the default Local Peering Gateway (LPG) on the OCI side, which automatically routes GCP traffic to the VCN subnets.
- C
Create the necessary route rules and associated route table on the OCI side to direct traffic towards OCI� private subnets through the DRG attachment.
- D
Configure a NAT Gateway on OCI to translate outbound traffic from GCP before it reaches the database.
Show answer and explanation
Correct answers: A, C
Explanation
When configuring Oracle Interconnect for Google Cloud, you must provision a Cloud Router in Google Cloud and create VLAN attachments pointing to OCI� DRG. In OCI, you must ensure that the DRG is set up with appropriate route rules. This setup allows bidirectional forwarding of private traffic between Google Cloud VPCs and OCI VCNs. For further details, consult Oracle� 'Setting Up Oracle Interconnect for Google Cloud' documentation, which outlines recommended steps and best practices.
- A. Correct.
Option 1 is correct. Setting up a Cloud Router in Google Cloud and attaching it to a VLAN for the OCI Interconnect is essential. You establish a BGP session between the Cloud Router and the OCI DRG to exchange route information, enabling direct private connectivity.
- B. Incorrect.
Option 2 is incorrect. A Local Peering Gateway (LPG) in OCI is used for peering two VCNs within OCI and does not automatically facilitate connectivity with external clouds. Merely enabling an LPG does not route Google Cloud traffic to OCI.
- C. Correct.
Option 3 is correct. You must create and configure the appropriate route rules in your OCI environment so that traffic destined for your OCI-based database subnets is forwarded through the DRG attachment. Without proper route rules on the OCI side, traffic from GCP would not know where to go.
- D. Incorrect.
Option 4 is incorrect. A NAT Gateway in OCI translates outbound traffic to public IP addresses, typically for internet-bound traffic. It is not used for private, low-latency connectivity over Oracle Interconnect for Google Cloud.
