Show answer & explanationAnswer & explanation
Correct answer: B. AWS Direct Connect
AWS Direct Connect provides a dedicated, private network connection from your premises to AWS. This offers consistent network performance, higher bandwidth options, and lower latency compared to internet-based connections like VPN, making it ideal for high throughput and low latency requirements.
Why the other options are wrong
- A. An Internet Gateway connects a VPC to the public internet, not a private connection to an on-premises data center.
- C. AWS Site-to-Site VPN uses the public internet, which does not guarantee high throughput or low latency.
- D. VPC Peering connects two VPCs within AWS, not an on-premises data center to a VPC.
