1Z0-1151-25 Question 16
Select 2You are designing a multi-cloud architecture for an application that runs front-end services in Microsoft Azure and uses Oracle Autonomous Database in Oracle Cloud Infrastructure (OCI) to store user data. The company has strict requirements for low-latency data access and secure connectivity. Which two connectivity strategies would best meet these requirements?
- A
Use the public internet with a NAT Gateway for routing traffic from Azure services to OCI
- B
Implement Oracle Interconnect for Azure to establish a dedicated, private network connection
- C
Create an open-source VPN over a public IP to tunnel traffic between Azure and OCI
- D
Leverage a third-party interconnection partner to connect Azure ExpressRoute with OCI FastConnect
Show answer and explanation
Correct answers: B, D
Explanation
When implementing OCI in tandem with other cloud providers like Azure, secure and performant cross-cloud connectivity is paramount. Oracle Interconnect for Azure offers a direct interconnection service that helps reduce latency, while a third-party partner approach connecting Azure ExpressRoute and OCI FastConnect similarly provides a dedicated, high-speed link. Both methods are recommended for ensuring secure and low-latency data flows, aligning with best practices as documented in Oracle's and Microsoft� respective multi-cloud integration guides.
- A. Incorrect.
Option 1: Incorrect. Relying on the public internet with a NAT Gateway can lead to higher latency and potentially lower security compared to dedicated, private connections. This approach does not satisfy the strict low-latency and security requirements.
- B. Correct.
Option 2: Correct. Oracle Interconnect for Azure provides a private, high-speed connection between Azure and OCI, reducing latency and securing data transmission. This addresses both the performance and security needs of the scenario.
- C. Incorrect.
Option 3: Incorrect. While a simple VPN can encrypt traffic, creating and managing a purely open-source VPN over public IP is less reliable for large-scale production workloads. It may also introduce higher latency compared to dedicated connections and does not fully meet strict low-latency requirements.
- D. Correct.
Option 4: Correct. A third-party interconnection partner integrates Azure ExpressRoute with OCI FastConnect, ensuring a private, dedicated, low-latency route. This option is commonly used by enterprises to streamline connectivity between cloud environments with robust performance and security.
