Answer: Set up an accelerator in AWS Global Accelerator. Configure Regional endpoint groups and health checks.
The question revolves around ensuring the highest availability for data transmission from IoT devices to AWS infrastructure, considering the global presence of operation centers and the need for quick data delivery. Option A, using Amazon CloudFront with origin failover, provides content delivery network (CDN) services but does not directly address the need for high availability in data transmission from IoT devices. Option B, setting up Route 53 latency-based routing with Evaluate Target Health set to Yes, improves DNS resolution based on latency and health checks but does not directly manage the data transmission path for high availability. Option D, using Bring Your Own IP (BYOIP) addresses, allows for the use of the same IP addresses across regions but does not inherently provide a mechanism for high availability in data transmission. Option C, setting up an accelerator in AWS Global Accelerator with Regional endpoint groups and health checks, directly addresses the need for high availability by routing traffic through the AWS global network to the optimal endpoint based on health, location, and policy, thus ensuring the fastest and most reliable data transmission from IoT devices to AWS infrastructure. Therefore, the best solution for meeting the requirements with the highest availability is Option C.

An international company providing tsunami early warnings plans to deploy IoT devices globally to monitor sea waves. The IoT devices must transmit collected data to the company’s AWS infrastructure with minimal latency. The company operates three global centers, each connected to AWS via its own AWS Direct Connect link and to the internet through at least two upstream ISPs. The company uses its own provider-independent (PI) address space, and the IoT devices rely on TCP for reliable data transmission, with both landline and mobile internet connectivity. The solution spans multiple AWS Regions, and Amazon Route 53 is used for DNS services.
What connectivity design between the IoT devices and AWS Cloud services will ensure the HIGHEST availability?
A
Set up an Amazon CloudFront distribution with origin failover. Create an origin group for each Region where the solution is deployed.
B
Set up Route 53 latency-based routing. Add latency alias records. For the latency alias records, set the value of Evaluate Target Health to Yes.
C
Set up an accelerator in AWS Global Accelerator. Configure Regional endpoint groups and health checks.
D
Set up Bring Your Own IP (BYOIP) addresses. Use the same PI addresses for each Region where the solution is deployed.
