1Z0-997-25 Question 104
Single answerYour company runs data-intensive workloads on-premises and needs to extend these workloads to the cloud for additional compute and analytics. You have strict latency requirements for real-time data processing, along with security and compliance constraints. The organization also wants to leverage Azure for machine learning capabilities. Which approach would best enable low-latency, secure connectivity among the on-premises environment, Oracle Cloud Infrastructure (OCI), and Azure?
- A
Configure a site-to-site VPN for all traffic between on-premises, OCI, and Azure using the public Internet.
- B
Establish a dedicated FastConnect connection from on-premises to OCI and leverage the Oracle-Azure Interconnect for cross-cloud connectivity.
- C
Deploy all workloads solely in OCI using public endpoints for Azure-based machine learning services.
- D
Implement a high-performance computing (HPC) cluster in OCI and synchronize data to Azure Storage via object-based replication over the Internet.
Show answer and explanation
Correct answer: B
Explanation
Using a private, dedicated connection such as OCI FastConnect for the on-premises to OCI link provides low-latency, high-throughput connectivity essential for real-time workloads under strict compliance requirements. Meanwhile, the Oracle-Azure Interconnect offers a direct, dedicated network path between the two clouds, further reducing latency and improving security. This aligns with recommended best practices for hybrid and multicloud deployments detailed in OCI networking documentation (see Oracle documentation on FastConnect and Azure Interconnect for reference).
- A. Incorrect.
Option 1 (Incorrect): A site-to-site VPN tunnel over the public Internet may be simpler short term, but it often introduces higher latency and potential bottlenecks. This approach may also raise compliance concerns given that traffic traverses the public Internet.
- B. Correct.
Option 2 (Correct): This option meets the real-time and compliance needs by using FastConnect for a private, dedicated link from on-premises to OCI, eliminating common latency issues of the public Internet. The Oracle-Azure Interconnect provides a direct, high-bandwidth, low-latency path between Oracle Cloud and Azure, enabling hybrid and multicloud workloads.
- C. Incorrect.
Option 3 (Incorrect): Running everything in OCI and calling Azure services over the public Internet could solve some management complexity but would not address stringent latency or compliance requirements. Public endpoints can introduce latency and potential security exposure.
- D. Incorrect.
Option 4 (Incorrect): While HPC clusters in OCI can handle computationally intensive tasks, relying on public Internet for data synchronization to Azure does not align with strict latency or security requirements, making it less suitable for real-time or highly sensitive data scenarios.
