1Z0-1123-25 Question 27
Single answerYou are designing the network connectivity strategy for a large enterprise moving its on-premises data center workloads to Oracle Cloud Infrastructure (OCI). The project requirements include replicating large volumes of data with minimal latency and ensuring consistent, dedicated bandwidth for ongoing data transfers. The enterprise� data center is located near an OCI FastConnect location, and application-level encryption is already in place. Which OCI connectivity option best meets these requirements?
- A
Establish a VPN Connect (IPsec) tunnel for encrypted traffic over the public Internet
- B
Use Oracle FastConnect private peering for dedicated connectivity
- C
Configure Remote Peering across regions using a DRG
- D
Leverage a NAT Gateway in your VCN to route on-premises traffic
Show answer and explanation
Correct answer: B
Explanation
Oracle FastConnect is designed for reliable, high-bandwidth, and low-latency connectivity between on-premises data centers and OCI. By avoiding the public Internet, FastConnect helps ensure consistent performance, which is crucial for large-scale data replication. Refer to the Oracle documentation at https://docs.oracle.com/en-us/iaas/Content/Network/Concepts/fastconnect.htm for more details on FastConnect capabilities and best practices.
- A. Incorrect.
Option 1 (Establish a VPN Connect) is incorrect. While a VPN Connect tunnel does provide encryption and a simpler initial setup, it does not guarantee dedicated bandwidth or consistent throughput, which makes it less suitable for large-scale data replication requiring minimal latency.
- B. Correct.
Option 2 (Use Oracle FastConnect) is correct. FastConnect offers dedicated, private connectivity with guaranteed bandwidth and lower latency, making it ideal for high-volume data replication scenarios. Since the data center is near a FastConnect location and application-level encryption is already in place, this is the optimal choice.
- C. Incorrect.
Option 3 (Configure Remote Peering) is incorrect. Remote Peering is used to connect two virtual cloud networks (VCNs) across regions. It does not replace the need for a dedicated or VPN connection from on-premises to OCI and does not solve the requirement for guaranteed performance and minimal latency.
- D. Incorrect.
Option 4 (Leverage a NAT Gateway) is incorrect. A NAT Gateway facilitates outbound traffic from a private subnet to the public Internet without exposing private IP addresses. It does not provide dedicated connectivity for large-scale data replication from on-premises to OCI.
