1Z0-1151-25 Question 57
Single answerA multinational e-commerce company deploys its front-end applications in AWS but stores customer and product data in an Oracle Database running on Oracle Cloud Infrastructure (OCI). They need a high-throughput connection and seamless data replication between AWS and OCI. They also require a backup connection in case the primary link fails. Which connectivity strategy best fulfills these requirements?
- A
Use only a Site-to-Site VPN tunnel from the AWS VPC to the OCI Dynamic Routing Gateway (DRG) for all traffic
- B
Set up Oracle FastConnect exclusively without any additional redundancy option
- C
Establish Oracle FastConnect as the primary link and configure a Site-to-Site VPN tunnel for redundancy
- D
Rely on an AWS Direct Connect link alone to replicate data directly into the OCI Virtual Cloud Network (VCN)
Show answer and explanation
Correct answer: C
Explanation
In multi-cloud deployments where predictable performance, low latency, and high reliability are vital, Oracle FastConnect offers a dedicated private connection to OCI with guaranteed bandwidth. However, it is recommended to pair it with a Site-to-Site VPN tunnel as a cost-effective and secure failover option. This approach aligns with best practices outlined in Oracle� documentation for mission-critical workloads, ensuring continuous connectivity even if the primary FastConnect link experiences issues.
- A. Incorrect.
Option 1 is incorrect because using only a Site-to-Site VPN for all traffic may struggle to deliver the consistent bandwidth and low latency required, especially under large-scale e-commerce loads. VPN connections can handle secure traffic but do not guarantee the dedicated bandwidth of a private connection.
- B. Incorrect.
Option 2 is incorrect because, while FastConnect provides a dedicated, high-bandwidth connection, it does not include a fallback path. In case of any FastConnect outage, there might be no alternate route, causing potential downtime.
- C. Correct.
Option 3 is correct because establishing FastConnect for primary performance requirements and adding a Site-to-Site VPN backup ensures both high-speed connectivity and redundancy. This is considered a best practice for mission-critical workloads that need guaranteed bandwidth with a secure failover option.
- D. Incorrect.
Option 4 is incorrect because AWS Direct Connect cannot directly terminate in an Oracle VCN without additional cross-cloud routing and partnerships. It might serve as part of a multi-cloud strategy, but by itself, it does not provide an AWS-to-OCI link over Oracle� own FastConnect infrastructure or a backup path in OCI.
