1Z0-1151-25 Question 56
Single answerA multinational retailer has deployed a sales analytics application across Oracle Cloud Infrastructure (OCI) and Microsoft Azure. They want to transfer large datasets between both environments securely, with minimal latency and reduced data egress costs. Which option best meets these requirements?
- A
Establish an IPsec VPN over the public internet between Azure and OCI
- B
Use the Oracle Interconnect for Microsoft Azure in a supported region
- C
Set up a site-to-site VPN from on-premises to OCI, then route traffic to Azure
- D
Implement a custom network appliance on an OCI Compute instance for traffic bridging
Show answer and explanation
Correct answer: B
Explanation
When setting up a multicloud environment between Oracle Cloud Infrastructure and Microsoft Azure, the recommended approach for high-bandwidth and low-latency connectivity is to leverage the Oracle Interconnect for Microsoft Azure. This service creates a private connection between the two clouds, minimizing the reliance on the public internet for data transfer and reducing egress costs. For more information, reference official Oracle documentation on 'Interconnect for Microsoft Azure' best practices.
- A. Incorrect.
Option A is incorrect. While an IPsec VPN is secure, it traverses the public internet, leading to higher latency and potential bandwidth limitations compared to a dedicated interconnect. This can increase data transfer times and operational costs for large-scale datasets.
- B. Correct.
Option B is correct. The Oracle Interconnect for Microsoft Azure provides a direct private connection between OCI and Azure, reducing network latency and data egress costs. It is specifically designed for high-throughput, low-latency workloads, making it ideal for large-scale data transfer in this scenario.
- C. Incorrect.
Option C is incorrect. Although connecting on-premises to OCI and then routing to Azure may provide some security benefits, it introduces additional network hops and complexity. It is neither the most direct nor the most cost-effective solution for traffic strictly between OCI and Azure.
- D. Incorrect.
Option D is incorrect. A custom network appliance on OCI would require complex configuration and ongoing maintenance. It also cannot provide the same performance or cost optimization as a dedicated interconnect service designed for OCI-Azure communication.
