1Z0-1151-25 Question 107
Single answerYour organization wants to run a production-grade Oracle Database on Google Cloud while most application services remain on Oracle Cloud Infrastructure (OCI). To ensure secure, high-bandwidth, and low-latency connectivity between OCI and the Oracle Database running on Google Cloud, which solution should you implement?
- A
Establish a dedicated private interconnect (Partner Interconnect) between OCI and Google Cloud for end-to-end private routing.
- B
Use a standard public internet connection encrypted via SSL/TLS for traffic between OCI and Google Cloud.
- C
Set up a single IPsec VPN tunnel from the Oracle Database VM on Google Cloud to an OCI virtual cloud network (VCN).
- D
Enable Oracle Data Guard in maximum protection mode between the Oracle Database instance on Google Cloud and OCI.
Show answer and explanation
Correct answer: A
Explanation
When implementing Oracle Database on Google Cloud alongside services running on OCI, secure and predictable connectivity is paramount. The recommended approach is to use a private interconnect (Partner Interconnect) between OCI and Google Cloud, as documented in official Oracle Cloud and Google Cloud connectivity references. This private link ensures high bandwidth and low latency, critical for performance-sensitive Oracle databases.
- A. Correct.
Option 1 is correct because using a dedicated private interconnect (Partner Interconnect) between OCI and Google Cloud provides a secure, high-speed link that avoids exposure to the public internet. This approach ensures low latency, higher throughput, and more consistent performance for cross-cloud operations, which is crucial for production database workloads. It's a recommended best practice when integrating OCI services with databases running on Google Cloud.
- B. Incorrect.
Option 2 is incorrect because relying on the public internet, even with SSL/TLS encryption, might introduce unpredictable latency, bandwidth limitations, and potential bottlenecks. While data is encrypted, this method does not guarantee the performance needed for production-grade database connectivity.
- C. Incorrect.
Option 3 is incorrect because a single IPsec VPN tunnel can become a performance bottleneck for enterprise workloads and can introduce more overhead compared to a dedicated interconnect. VPN tunnels are commonly used for smaller-scale or non-critical traffic, not high-volume production database workloads.
- D. Incorrect.
Option 4 is incorrect because Oracle Data Guard addresses high availability and disaster recovery concerns rather than improving network connectivity or throughput. While Data Guard is valuable for replication and failover, it does not solve the requirement for direct, low-latency network connectivity between OCI and Google Cloud.
