1Z0-997-25 Question 115
Single answerYour organization is running a customer portal in Oracle Cloud Infrastructure (OCI) but relies on real-time data from an analytics service in another public cloud. You want to architect a reliable, low-latency, and secure data exchange between these two environments. Which approach provides the most effective multi-cloud network connectivity for this scenario?
- A
Establish an encrypted VPN over the public Internet between OCI and the other cloud
- B
Use OCI FastConnect and the other cloud� equivalent dedicated network link through a common carrier
- C
Leverage object storage cross-region replication via the public Internet
- D
Set up a file transfer protocol (FTP) server in a DMZ and synchronize data periodically
Show answer and explanation
Correct answer: B
Explanation
A dedicated private connection, such as OCI FastConnect paired with an equivalent service from another cloud provider (e.g., AWS Direct Connect or Azure ExpressRoute), delivers the most consistent performance and security. These services avoid public Internet congestion, reduce latency, and support reliable high-throughput data transfers. Relevant documentation includes Oracle� Multi-Cloud Network Connectivity guides, which recommend FastConnect and dedicated partner circuits for production-grade multi-cloud architectures.
- A. Incorrect.
Option 1 (VPN over the public Internet) provides security but may introduce higher latency and variability due to public Internet routing. It� a valid fallback DR or short-term solution but not ideal for real-time, high-bandwidth needs.
- B. Correct.
Option 2 (OCI FastConnect and the other cloud� dedicated link) is the best solution for predictable, low-latency, and secure connectivity across clouds. The dedicated links bypass the public Internet, reducing latency and providing better throughput.
- C. Incorrect.
Option 3 (Object storage cross-region replication) only addresses asynchronous replication of data rather than real-time data exchange, leading to potential delays and not solving the latency requirement.
- D. Incorrect.
Option 4 (FTP server in a DMZ) can be used for batch data transfers but does not meet the requirement for real-time, low-latency communication. It also adds overhead and complexity in managing a dedicated FTP service.
