1Z0-1072-25 Question 99
Single answerYou are migrating a high-performance computing (HPC) workload that requires large amounts of data to be transferred daily between your on-premises data center and Oracle Cloud Infrastructure (OCI). The workload demands consistent bandwidth and low latency. Which solution should you implement to best meet these requirements?
- A
Configure an IPSec VPN connection over the public Internet to transfer data securely.
- B
Use OCI FastConnect to establish a dedicated private connection with guaranteed bandwidth.
- C
Enable a NAT Gateway in OCI to manage outbound communication for HPC and rely on the public network.
- D
Set up a Local Peering Gateway to directly connect the on-premises network to the OCI Virtual Cloud Network.
Show answer and explanation
Correct answer: B
Explanation
For workloads that demand high throughput and low latency, Oracle Cloud Infrastructure FastConnect provides a direct and dedicated private link between your on-premises network and OCI. Unlike IPSec VPN over the public Internet, FastConnect performance is not subject to Internet traffic congestion. NAT Gateway and Local Peering Gateway each serve different purposes within OCI networking and do not address the need for guaranteed private bandwidth from on-premises. Refer to the Oracle documentation on FastConnect (https://docs.oracle.com/en/solutions/fastconnect/) for detailed guidance and best practices.
- A. Incorrect.
Incorrect. While IPSec VPN provides encryption over the public Internet, it does not guarantee dedicated bandwidth or the low latency typically required for HPC workloads. Bandwidth can fluctuate because traffic competes with other Internet traffic.
- B. Correct.
Correct. OCI FastConnect offers a dedicated, private, high-bandwidth connection to Oracle� network edge, providing predictable performance and low latency, which is crucial for HPC workloads and large data transfers.
- C. Incorrect.
Incorrect. A NAT Gateway translates internal private addresses to outbound connections over the Internet. It is not designed to provide high-throughput, dedicated connectivity for large data transfers and cannot guarantee consistent data transfer rates.
- D. Incorrect.
Incorrect. A Local Peering Gateway (LPG) allows VCN-to-VCN traffic within the same region without transiting the public Internet, but it does not provide a dedicated private connection from on-premises to OCI. It is used for communication between OCI resources in different VCNs.
