1Z0-1151-25 Question 62
Single answerYour organization needs a stable, high-bandwidth connection from its on-premises data center to Oracle Cloud Infrastructure (OCI) while also providing an option to expand connectivity to other public cloud providers in the future. Current forecasts show sustained traffic peaks exceeding 5 Gbps. Which strategy best meets these requirements for both the initial OCI deployment and future multi-cloud expansions?
- A
Establish a single IPsec VPN tunnel from on-premises to OCI for all traffic and plan to create additional VPN tunnels to each new cloud provider.
- B
Use FastConnect from on-premises to OCI and leverage a partner exchange to seamlessly add private peering to other cloud providers when needed.
- C
Set up multiple discrete FastConnect circuits connecting on-premises to each cloud provider individually for maximum traffic isolation.
- D
Configure all multi-cloud traffic to route over the public internet and enable SSL/TLS for end-to-end encryption.
Show answer and explanation
Correct answer: B
Explanation
FastConnect offers dedicated connectivity with predictable performance for high-bandwidth requirements, making it an ideal solution for connecting on-premises environments to OCI. By pairing FastConnect with a partner exchange (e.g., Equinix, Megaport), you can extend your private connectivity to additional public cloud providers without setting up multiple physical circuits. This approach aligns with OCI best practices for multi-cloud networking. For more information, refer to the official Oracle Cloud Infrastructure documentation on FastConnect and Partner Connectivity.
- A. Incorrect.
Incorrect. While a single IPsec VPN tunnel can be quick to set up, it relies on the public internet, which often lacks the consistent performance needed for sustained traffic over 5 Gbps. Adding separate VPN tunnels to each future cloud provider can become cumbersome.
- B. Correct.
Correct. Using FastConnect provides a dedicated, low-latency path to OCI with consistent performance for high-bandwidth traffic. A partner exchange allows you to create private connections to additional cloud providers without deploying separate circuits for each provider.
- C. Incorrect.
Incorrect. Though multiple discrete FastConnect circuits can isolate traffic, it is more expensive and complex if you plan to connect to many clouds. A partner exchange simplifies connectivity by extending your existing FastConnect for new cloud endpoints using private peering.
- D. Incorrect.
Incorrect. Routing all multi-cloud traffic over the public internet can introduce latency and performance variability, especially at sustained 5 Gbps throughput. Even with encryption, it does not guarantee the required level of consistency.
