1Z0-1151-25 Question 119
Single answerYour organization is migrating a critical business application to Oracle Database@Google Cloud. The application� microservices run on Oracle Cloud Infrastructure (OCI), and you must ensure a secure, low-latency connection between OCI and Google Cloud for database queries. Which approach best addresses the performance and security requirements for this integration?
- A
Implement the Oracle-Google Cloud Interconnect to establish a dedicated, high-bandwidth connection between OCI and Google Cloud for Oracle Database traffic.
- B
Rely on standard public internet routing for all database connections to reduce configuration overhead and simplify management.
- C
Use manually configured SSH tunnels from the OCI microservices layer to the Oracle Database@Google Cloud instances.
- D
Leverage a single load balancer in OCI that proxies all database connections over a site-to-site IPsec VPN.
Show answer and explanation
Correct answer: A
Explanation
Oracle Database@Google Cloud can be seamlessly integrated with OCI using the Oracle-Google Cloud Interconnect to provide a secure, dedicated connection that ensures low latency and high performance. This approach is recommended for production-grade workloads and aligns with best practices described in Oracle and Google Cloud documentation. For more details, consult the Oracle Database@Google Cloud documentation and Oracle-Google Cloud Interconnect guides, which outline deployment architectures, configuration steps, and network considerations.
- A. Correct.
Option 1 is correct. The Oracle-Google Cloud Interconnect provides a dedicated cross-cloud link that offers low latency and high bandwidth. This architecture helps ensure secure, high-performance connectivity, reducing network hops and minimizing the chance of network congestion or performance variability. It is the recommended approach for mission-critical applications that need consistent, low-latency access to their Oracle databases hosted on Google Cloud.
- B. Incorrect.
Option 2 is incorrect. While using the public internet is simpler, it introduces unpredictable latency and potential security risks. It does not provide a dedicated link, making performance and security difficult to guarantee for critical workloads.
- C. Incorrect.
Option 3 is incorrect. SSH tunnels are suitable for occasional administrative needs but are not ideal for large-scale production traffic. Maintaining multiple tunnels can become complex, and performance might degrade under heavy loads.
- D. Incorrect.
Option 4 is incorrect. A single load balancer and a site-to-site VPN can offer some security, but they typically do not provide the same performance and dedicated throughput that the Oracle-Google Cloud Interconnect delivers. A VPN tunnel can introduce higher latency and more management overhead for enterprise-scale usage.
