Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 408 discussion

Key words: geographically dispersed, UDP. Geographically dispersed (related to UDP) - Global Accelerator - multiple entrances worldwide to the AWS network to provide better transfer rates. UDP - NLB (Network Load Balancer).

Answer should be B.. there is typo mistake in B. Correct Answer is : Use AWS Global Accelerator. Create a Network Load Balancer (NLB) in each of the two Regions as an endpoint. Create an Amazon Elastic Container Service (Amazon ECS) cluster with the Fargate launch type. Create an ECS service on the cluster. Set the ECS service as the target for the NLB. Process the data in Amazon ECS.

if its UDP it has to be Global Accelarator + NLB package, plus it has the provision for rapid failover as well, piece of cake.

UDP: NLB + AWS Global Accelerator

UDP/TCP=NLB rapid failover= AWS global accelerator

devices that use UDP = NLB

This option meets the requirements: Global Accelerator provides UDP support and minimizes latency using the AWS global network. Using NLBs allows the UDP traffic to be load balanced across Availability Zones. ECS Fargate provides rapid scaling and failover across Regions. NLB endpoints allow rapid failover if one Region goes down.

UDP = AWS Global Accelerator and Network Load Balancer

Global accelerator for multi region automatic failover. NLB for UDP.

why not A?

To meet the requirements of minimizing latency for data transmission from the devices and providing rapid failover to another AWS Region, the best solution would be to use AWS Global Accelerator in combination with a Network Load Balancer (NLB) and Amazon Elastic Container Service (Amazon ECS). AWS Global Accelerator is a service that improves the availability and performance of applications by using static IP addresses (Anycast) to route traffic to optimal AWS endpoints. With Global Accelerator, you can direct traffic to multiple Regions and endpoints, and provide automatic failover to another AWS Region.
