1Z0-1151-25 Question 114
Single answerA retail company has its e-commerce application running on Google Cloud, but they want to leverage Oracle Database hosted in Oracle Cloud Infrastructure (OCI). They must ensure low-latency communication between the Google Cloud environment and the Oracle Database, along with a secure, reliable connection to handle peak shopping traffic. Which solution is most appropriate to achieve these objectives using the Oracle Database@Google Cloud architecture?
- A
Use the dedicated, private interconnect between Google Cloud and OCI (FastConnect on OCI and Partner Interconnect on Google Cloud) to provide secure, high-bandwidth, low-latency connectivity.
- B
Run Oracle Database as a Google Cloud SQL instance and sync with Oracle Cloud Infrastructure using standard public Internet routing.
- C
Create a public load balancer on Google Cloud to forward traffic to the Oracle Database endpoint in OCI over the Internet, maintaining encryption at the application layer only.
- D
Deploy Oracle Database on Google Cloud Compute Engine instances and utilize standard VPN tunnels to connect back to OCI core services.
Show answer and explanation
Correct answer: A
Explanation
For Oracle Database@Google Cloud architectures, the best practice is to deploy Oracle Database in Oracle Cloud Infrastructure while establishing a secure, private, and high-throughput link to the application in Google Cloud. The most robust way to accomplish this is with OCI FastConnect paired with Google Cloud Partner Interconnect, which avoids the latency and security risks inherent in public Internet routes. Refer to Oracle documentation on Multicloud Interconnectivity with Google Cloud (and the OCI FastConnect and Google Cloud Partner Interconnect documentation) for detailed setup instructions and best practices.
- A. Correct.
Correct: Configuring a dedicated private interconnect between OCI (FastConnect) and Google Cloud (Partner Interconnect) provides predictable performance, lower latency, and secure data transfer. This approach avoids routing traffic over the public Internet, meeting the requirements of high reliability and throughput. It is the recommended method to integrate Oracle Database in OCI with applications running on Google Cloud.
- B. Incorrect.
Incorrect: Google Cloud SQL does not support Oracle Database, so you cannot run a fully managed Oracle instance through Cloud SQL. Moreover, relying on public Internet routing can introduce latency and potential instability not suitable for critical workloads.
- C. Incorrect.
Incorrect: Although encrypting traffic at the application layer improves security, routing over the public Internet with a public load balancer can lead to unpredictable latency and bandwidth constraints. This approach does not provide the consistent performance required for enterprise-class databases.
- D. Incorrect.
Incorrect: Running Oracle Database on Google Cloud Compute Engine is not an officially supported path for a fully licensed Oracle Database production environment at the scale this scenario requires. Also, relying on standard VPN tunnels typically does not offer the same level of performance or reliability as a dedicated interconnect.
