A global company is connecting its primary and secondary data centers and a VPC and needs to maximize resiliency and fault tolerance for connections. Required bandwidth must exceed 10 Gbps and the solution should be cost-effective. Which option meets these needs most economically?

Correct answer: Set up two 10 Gbps connections at the primary data center that terminate at one AWS Direct Connect location. Ensure the connections are managed by separate providers. Set up two 10 Gbps connections at the secondary data center that terminate at a second Direct Connect location. Ensure the connections are managed by separate providers..
Why this is the answer
The correct option provides the required bandwidth exceeding 10 Gbps (two 10 Gbps connections per data center offer 20 Gbps aggregate), maximizes resiliency and fault tolerance by using multiple connections to separate Direct Connect locations and separate providers, and is cost-effective compared to 100 Gbps connections. The first incorrect option uses 100 Gbps connections, which are significantly more expensive and exceed the "exceed 10 Gbps" requirement unnecessarily, making it less cost-effective. The second incorrect option uses only one 10 Gbps connection per data center, which does not meet the "exceed 10 Gbps" bandwidth requirement. The fourth incorrect option uses a Site-to-Site VPN for the secondary data center, which typically has lower bandwidth and higher latency compared to Direct Connect, and would not meet the "exceed 10 Gbps" requirement for a resilient, high-bandwidth connection.
