Q1156. A finance company is migrating its trading platform to AWS. The trading platform processes a high volume of market data and processes stock trades. The company needs to establish a consistent, low-latency network connection from its on-premises data center to AWS.The company will host resources in a VPC. The solution must not use the public internet.Which solution will meet these requirements?

Correct Answer: B. Use AWS Direct Connect to set up a connection from the on-premises data center to AWS.

Explanation

The solution that best meets the requirements for establishing a consistent, low-latency network connection from the on-premises data center to AWS without using the public internet is:B. Use AWS Direct Connect to set up a connection from the on-premises data center to AWS.AWS Direct Connect: This service provides a dedicated, private network connection between your on- premises data center and AWS. It offers lower latency and more consistent performance compared to internet-based connections.Consistent Low Latency: Direct Connect is ideal for high-volume data processing and applications like a trading platform, where low-latency connectivity is critical. This solution effectively meets the company's requirements for secure and reliable connectivity to AWS.To establish a consistent, low-latency network connection from an on-premises data center to AWS without using the public internet, the best solution is:Key Requirements:Low-latency connection (for high-volume market data and trading).No public internet usage (private and secure).Connectivity to an AWS VPC.Option Analysis:A. Use AWS Client VPN to connect the on-premises data center to AWS. Client VPN is designed for individual users to connect to AWS (not for data center-to-AWS connectivity). It uses the public internet (not suitable for low-latency, private connections).Not suitable for this use case.B. Use AWS Direct Connect to set up a connection from the on-premises data center to AWS. Direct Connect provides a dedicated, private network connection between on-premises and AWS. It offers low latency and high bandwidth (ideal for high-volume trading data).It does not use the public internet.Best fit for this requirement.C. Use AWS PrivateLink to set up a connection from the on-premises data center to AWS. PrivateLink is used to securely access AWS services (like EC2, S3, or custom endpoints) over a private network.However, it is not a direct connection from on-premises to AWS--it requires a VPN or Direct Connect as the underlying transport.Not a standalone solution for on-premises-to-AWS connectivity. D. Use AWS Site-to-Site VPN to connect the on-premises data center to AWS. Site-to-Site VPN provides a secure connection over the public internet (using IPsec tunnels). While it is private and encrypted, it does use the public internet, which may introduce latency and variability.Not ideal for low-latency, high-volume trading.Correct Answer:B. Use AWS Direct Connect to set up a connection from the on-premises data center to AWS.This solution provides:Dedicated, private connectivity (no public internet).Low latency (critical for trading platforms).High bandwidth (for high-volume market data).Final Answer:B. Use AWS Direct Connect to set up a connection from the on-premises data center to AWS.
