1Z0-1151-25 Question 106
Select 2Your enterprise is migrating a mission-critical financial application to Google Cloud. You plan to host the Oracle Database on Google Cloud (Oracle Database@Google Cloud), but you also need to interoperate with an Oracle Cloud Infrastructure (OCI) HPC cluster for advanced risk simulations. To ensure direct, secure, and low-latency access to the database from your OCI-based HPC cluster, which two actions are essential in this scenario?
- A
A. Use Google Cloud Partner Interconnect or Dedicated Interconnect in conjunction with OCI FastConnect through a common colocation provider.
- B
B. Configure ephemeral public IP addresses for database nodes in Google Cloud so OCI resources can reach the database over the public internet.
- C
C. Deploy an IPSec VPN tunnel from Google Cloud to OCI without configuring any routing beyond default settings.
- D
D. Set up route advertisements in both Google Cloud and OCI to ensure traffic targeting the database uses the private interconnect path.
Show answer and explanation
Correct answers: A, D
Explanation
In a multi-cloud environment using Oracle Database@Google Cloud and OCI for HPC workloads, establishing a dedicated or partner interconnect paired with OCI FastConnect is crucial for achieving low latency and high bandwidth. Additionally, correct route advertisements on both sides ensure your traffic remains on the private and more performant links. These methods align with recommended best practices for secure and scalable multi-cloud architectures, as outlined in official OCI and Google Cloud documentation.
- A. Correct.
A. Correct. Google Cloud Partner Interconnect or Dedicated Interconnect can be paired with OCI FastConnect via a common colocation partner or direct connection, offering secure, high-bandwidth, and low-latency connectivity between GCP and OCI. This setup is a recognized best practice for mission-critical workloads that require efficient, private traffic flows across clouds.
- B. Incorrect.
B. Incorrect. Relying on ephemeral public IP addresses for database traffic introduces unnecessary latency, potential bandwidth limits, and security risks. Public internet routing generally does not meet the stringent performance or security requirements of HPC and database workloads.
- C. Incorrect.
C. Incorrect. While an IPSec VPN tunnel can provide secure connectivity, it typically does not offer the same throughput or latency advantages as a dedicated private interconnect. Relying on default routing without careful planning also risks suboptimal data paths.
- D. Correct.
D. Correct. Proper route advertisements (e.g., BGP) on both GCP and OCI ensure that traffic between the HPC cluster and the database flows through the private interconnect rather than taking a public path. This is crucial for optimizing latency and securing traffic.
