1Z0-1151-25 Question 77
Select 3Your organization wants to enable private connectivity between Oracle Cloud Infrastructure (OCI) and Google Cloud using Oracle Interconnect for Google Cloud. You have already provisioned your VCN in OCI and want to establish dynamic routing so that resources in both clouds communicate over private IP addresses. Which three configuration steps are required to properly set up BGP peering between OCI and Google Cloud using the Interconnect? (Choose three.)
- A
In OCI, create a Dynamic Routing Gateway (DRG) and attach your VCN to it, then configure a private virtual circuit for the interconnect.
- B
In Google Cloud, create a Cloud Router and a VLAN attachment, then configure BGP settings with distinct IP addresses for each endpoint.
- C
Enable FastConnect auto-provisioning in the OCI console by selecting your Google Cloud region, which automatically sets up all required routing on Google Cloud.
- D
Configure a single IP address for both the local (Google Cloud) and remote (OCI) endpoints in the Cloud Router BGP settings.
- E
Enable route propagation on both OCI� route tables and Google Cloud� routing configuration so that subnets in each environment learn each other� routes automatically.
Show answer and explanation
Correct answers: A, B, E
Explanation
Implementing Oracle Interconnect for Google Cloud requires configuring a DRG on OCI (with a VCN attachment and private virtual circuit) and setting up a Cloud Router with a VLAN attachment on Google Cloud. BGP peering is essential to exchange routes, which means assigning distinct IP addresses for each side. Finally, ensuring proper route propagation on both OCI and Google Cloud is critical for subnets to communicate across environments. For more details, consult Oracle� documentation on �Oracle Interconnect for Google Cloud� and Google Cloud� �Cloud Router and BGP configuration� best practices.
- A. Correct.
Option 1 is CORRECT. You must create a DRG in OCI and attach your VCN to it. Then, you set up a private virtual circuit for the interconnect to Google Cloud. This private virtual circuit allows communication through BGP between OCI and Google.
- B. Correct.
Option 2 is CORRECT. On Google Cloud, creating a Cloud Router and a VLAN attachment is essential for establishing a dedicated interconnect. Configuring BGP with unique local and remote IP addresses ensures that each side of the connection knows how to route traffic.
- C. Incorrect.
Option 3 is INCORRECT. There is no feature in OCI that automatically provisions all Google Cloud routing by simply selecting a region. You must manually configure both sides (OCI and Google Cloud) for the interconnect setup.
- D. Incorrect.
Option 4 is INCORRECT. BGP peering requires distinct IP addresses for the local and remote endpoints. You cannot use a single IP address for both endpoints, or the BGP session will fail to form.
- E. Correct.
Option 5 is CORRECT. To allow both OCI and Google Cloud to automatically learn each other� routes, you need to enable route propagation on the OCI side and ensure the Cloud Router is set to advertise and learn routes on the Google Cloud side.
