1Z0-997-25 Question 130
Single answerYou have just deployed an Oracle Database@Google Cloud instance, and you need to connect it securely to an Oracle Cloud Infrastructure (OCI) application over Oracle Interconnect for Google Cloud with minimal latency. Which approach correctly configures routing to ensure secure and reliable connectivity?
- A
Establish a site-to-site IPSec VPN between the OCI VCN and the Google Cloud VPC without configuring BGP.
- B
Configure global dynamic routing in both clouds, then use only Public IP addresses on the database and application subnets for interconnect traffic.
- C
Set up a Cloud Router with a VLAN attachment on the Google Cloud side and a Dynamic Routing Gateway (DRG) on the OCI side; enable BGP peering across the interconnect.
- D
Rely on the default route tables in both clouds and create a NAT Gateway in Google Cloud to forward all traffic to OCI.
Show answer and explanation
Correct answer: C
Explanation
To properly implement Oracle Interconnect for Google Cloud together with Oracle Database@Google Cloud, you need dedicated private connectivity rather than relying on public IP addresses or simple VPN tunnels. Configuring a Google Cloud Router and an OCI Dynamic Routing Gateway (DRG), then establishing BGP peering, is the recommended best practice for secure, high-performance connectivity. For more details, refer to Oracle and Google Cloud documentation regarding the Interconnect setup and networking requirements.
- A. Incorrect.
Incorrect. A site-to-site IPSec VPN alone does not leverage Oracle Interconnect for Google Cloud. It introduces additional overhead and may not provide the low latency or bandwidth required by high-performance database workloads.
- B. Incorrect.
Incorrect. Using only public IP addresses defeats the purpose of a private, low-latency interconnect and can introduce security risks. Oracle Interconnect for Google Cloud is designed for private connectivity, not public routing.
- C. Correct.
Correct. When using Oracle Interconnect for Google Cloud with an Oracle Database@Google Cloud, you must configure a Cloud Router in Google Cloud, attach a VLAN for the interconnect, and set up a DRG in OCI. BGP peering ensures proper dynamic routing between the two clouds, enabling secure, low-latency connections.
- D. Incorrect.
Incorrect. Simply depending on default route tables and a NAT gateway in Google Cloud is insufficient for private interconnect routing. This approach doesn�t correctly configure the dedicated low-latency path between OCI and Google Cloud.
