1Z0-1151-25 Question 52
Select 2Your organization is running a data analytics application on Oracle Cloud Infrastructure (OCI) that needs to pull large amounts of data from an Azure-based data lake in near real-time. You require a private, secure connection with low latency and guaranteed bandwidth between the two clouds. Which two configuration approaches should you consider to meet these requirements?
- A
Establish an IPsec site-to-site VPN tunnel between Azure VPN Gateway and an OCI Dynamic Routing Gateway
- B
Configure a cross-cloud interconnect by pairing Azure ExpressRoute with OCI FastConnect
- C
Expose Azure public endpoints for the data lake and restrict traffic using Network Security Groups (NSGs)
- D
Deploy a co-located cross-connect in a partner data center that provides private circuits to both Azure and OCI
Show answer and explanation
Correct answers: B, D
Explanation
When designing multicloud connectivity for data-intensive or latency-sensitive workloads, you need solutions that provide high-bandwidth, low-latency, and private links. Azure-OCI Interconnect (ExpressRoute + FastConnect) and co-located cross-connects are two proven methods that meet these requirements. IPsec VPN is secure but typically lacks guaranteed performance, making it less suitable for large-scale analytics workloads. Exposing data via public endpoints often introduces latency variability and security concerns, which contradict high-performance needs for HPC or analytics use cases. Refer to official Oracle and Azure connectivity documentation for detailed guidance on configuring dedicated interconnects and cross-connects.
- A. Incorrect.
Option 1: While an IPsec VPN tunnel is secure and easy to configure, it does not provide guaranteed bandwidth or optimal latency for large-scale data analytics workloads. IPsec VPN often introduces additional overhead and is typically used as a fallback or quick solution rather than for high-throughput data transfers.
- B. Correct.
Option 2: Using the Azure-OCI cross-cloud interconnect (combining Azure ExpressRoute with OCI FastConnect) is a recommended way to achieve private, low-latency, and higher-throughput connectivity between the two platforms. This approach helps meet the performance and security requirements of data-intensive applications.
- C. Incorrect.
Option 3: Relying on Azure public endpoints and restricting traffic with NSGs forces data to traverse the public internet, which typically cannot provide guaranteed bandwidth or the low-latency performance required for near real-time data analytics. It also adds unnecessary exposure to external networks.
- D. Correct.
Option 4: Deploying a co-located cross-connect in a partner data center that has physical connections to both Azure and OCI can provide a dedicated, private circuit with predictable bandwidth and latency. This approach is commonly used to ensure enterprise-grade connectivity and meets the performance demands of high-volume data transfers.
