AWS Certified Advanced Networking Specialty Practice Exam

How can you achieve low-latency connectivity from on-premises systems to AWS?

1. Using a site-to-site VPN connection

2. Establishing an AWS Direct Connect connection

3. Utilizing internet-based connections

4. Deploying a public API Gateway

The correct answer is: Establishing an AWS Direct Connect connection

Achieving low-latency connectivity from on-premises systems to AWS is best accomplished through establishing an AWS Direct Connect connection. This service allows you to create a dedicated network connection between your on-premises data center and AWS. Here’s why this answer is the most suitable option. AWS Direct Connect provides a reliable, consistent network experience with lower latency compared to standard internet connections. This is primarily because Direct Connect establishes a physical, dedicated line rather than relying on the public internet. Such a dedicated line reduces the number of hops and potential congestion points that could introduce delays in data transmission, resulting in improved performance and predictable networking behavior. Additionally, Direct Connect can facilitate higher bandwidth options and better overall data transfer rates, which can also contribute to reducing latency when transmitting data between your on-premises systems and AWS. Utilizing a site-to-site VPN connection, while it can establish a secure tunnel between your on-premises network and AWS, is typically subject to the inherent latencies of the public internet and can be impacted by factors outside your control, such as traffic conditions. Internet-based connections, in general, will also be at the mercy of the fluctuations and reliability of the internet, making them less favorable for low-latency requirements. Finally, deploying a public
