1Z0-1151-25 Question 59
Single answerYour organization is hosting a critical application in Oracle Cloud Infrastructure (OCI) that needs to securely and reliably exchange large volumes of data with a third-party cloud environment. They require dedicated, high-speed connectivity to handle frequent data transfers, and also want an encrypted backup path in case the primary connection fails. Which connectivity strategy best meets these requirements?
- A
A. Use FastConnect as the primary connection and an OCI Site-to-Site VPN as a fallback for secure failover.
- B
B. Deploy only an OCI Site-to-Site VPN with multiple tunnels to handle both primary and backup traffic.
- C
C. Use two FastConnect circuits at different edge locations without any VPN configuration.
- D
D. Rely on the public Internet for primary traffic and set up a single VPN connection as a standby.
Show answer and explanation
Correct answer: A
Explanation
FastConnect offers a dedicated, private, and high-bandwidth connection to OCI, making it the best option for frequent large data transfers. However, FastConnect alone does not provide an encrypted backup in case of failure. Therefore, adding an OCI Site-to-Site VPN ensures secure failover, maintaining connectivity even if the primary FastConnect link goes down. According to Oracle Cloud Infrastructure best practices, using FastConnect with a VPN for redundancy is a recommended approach for critical, high-volume, multicloud workloads.
- A. Correct.
A. Correct. Combining FastConnect for dedicated bandwidth and low latency with an OCI Site-to-Site VPN as a failover path ensures both high performance and encrypted backup connectivity. If the FastConnect link experiences downtime, secured tunnels over VPN can maintain traffic flow.
- B. Incorrect.
B. Incorrect. While an OCI Site-to-Site VPN with multiple tunnels provides redundancy, it does not offer the guaranteed bandwidth and performance of FastConnect, which is vital for large data transfers.
- C. Incorrect.
C. Incorrect. Although multiple FastConnect circuits in different locations provide redundancy, there is no encrypted fallback in case both circuits fail or experience issues. A separate VPN is advisable for secure failover traffic.
- D. Incorrect.
D. Incorrect. Relying on the public Internet for primary data transfers may introduce unpredictable performance, latency, and potential security risks compared to FastConnect and VPN options.
