Question

A media company is planning to host an event that the company will live stream to users. The company wants to use Amazon CloudFront. A network engineer creates a primary origin and a secondary origin for CloudFront.

Which solution will meet this requirement with the LEAST operational overhead?

Options

  • AConfigure a Lambda@Edge function to check the health status of both origins every 10 seconds.
  • BCreate a Network Load Balancer (NLB) in front of both origins. Configure the NLB as the origin in
  • CSet the CloudFront origin connection timeout value to 5 seconds. Set the origin connection
  • DConfigure a Lambda@Edge function to monitor incoming requests for an origin response. Reroute

Explanation

The solution involves using an NLB to manage the failover between the primary and secondary origins. The NLB automatically handles health checks for both origins and will route traffic to the healthy origin, providing a seamless failover within the required 15 seconds. This approach requires minimal operational overhead, as the NLB handles the routing and health checking without the need for custom code or manual intervention.
