Which solution meets these requirements?
Two AWS Direct Connect connections from the primary data center terminating at two Direct Connect locations on two separate devices
A single AWS Direct Connect connection from each of the primary and secondary data centers terminating at one Direct Connect location on the same device
Two AWS Direct Connect connections from each of the primary and secondary data centers terminating at two Direct Connect locations on two separate devices
A single AWS Direct Connect connection from each of the primary and secondary data centers terminating at one Direct Connect location on two separate devices
Explanations:
While two AWS Direct Connect connections from the primary data center provide redundancy, having connections only from the primary data center does not achieve maximum resiliency for both data centers. This setup could still lead to a single point of failure if the primary data center experiences issues.
A single AWS Direct Connect connection from each data center terminating at one Direct Connect location on the same device creates a single point of failure, as both connections would rely on the same device for connectivity. This does not provide maximum resiliency.
Two AWS Direct Connect connections from each of the primary and secondary data centers terminating at two separate Direct Connect locations on two different devices provide the highest level of resiliency. This setup ensures that if one data center, device, or connection fails, the other can still maintain connectivity, minimizing the risk of downtime.
A single AWS Direct Connect connection from each data center terminating at one Direct Connect location on two separate devices provides some redundancy, but it still has a potential single point of failure at the Direct Connect location. If that location encounters issues, it can disrupt connectivity for both data centers.
