1Z0-1123-25 Question 29
Select 2An electronics manufacturer is planning to migrate large on-premises datasets to OCI. They need to perform quick connectivity tests before going live, and subsequently require a dedicated, high-bandwidth link to ensure near-real-time data replication under heavy load. Which two OCI connectivity solutions best fulfill these requirements?
- A
Establish a Site-to-Site VPN (IPsec VPN) connection for initial testing
- B
Set up Oracle FastConnect for dedicated private connectivity
- C
Use an Internet Gateway for all traffic between on-premises and OCI
- D
Configure a Service Gateway for connecting to Oracle services over a private IP
Show answer and explanation
Correct answers: A, B
Explanation
In this scenario, using an IPsec VPN for initial testing and then adopting FastConnect for dedicated private connectivity is a common best practice. IPsec VPN connections can be quickly provisioned, allowing you to verify functionality and secure traffic before committing to the higher throughput and cost of FastConnect. Once production traffic ramps up, FastConnect� guaranteed bandwidth and lower latency become essential for large data migration and near-real-time replication (refer to Oracle documentation on 'FastConnect' and 'Site-to-Site VPN' for detailed implementation guidance).
- A. Correct.
A Site-to-Site VPN (IPsec VPN) allows quick setup and testing of secure connectivity. While IPsec VPN might not offer dedicated bandwidth for large data replication, it� a cost-effective and straightforward way to validate connectivity during a pilot or proof-of-concept phase.
- B. Correct.
FastConnect provides a private, dedicated connection with guaranteed bandwidth, making it ideal for large-scale data transfers and near-real-time replication needs. It ensures predictable performance and lower latency compared to an internet-based VPN.
- C. Incorrect.
An Internet Gateway allows traffic to flow between the public internet and OCI, but it does not guarantee the bandwidth or secure path needed for large-scale data replication. Relying on the public internet for mission-critical replication introduces potential congestion and lower performance.
- D. Incorrect.
A Service Gateway is used to connect to Oracle services (e.g., Object Storage) through a private IP address, bypassing the public internet. While useful within OCI, it does not address connectivity requirements from on-premises to OCI in the scenario described.
