Exam AWS Certified Advanced Networking - Specialty ANS-C01 topic 1 question 142 discussion

Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 142
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

An IoT company collects data from thousands of sensors that are deployed in the Unites States and South Asia. The sensors use a proprietary communication protocol that is built on UDP to send the data to a fleet of Amazon EC2 instances. The instances are in an Auto Scaling group and run behind a Network Load Balancer (NLB). The instances, Auto Scaling group, and NLB are deployed in the us-west-2 Region.

Occasionally, the data from the sensors in South Asia gets lost in transit over the internet and does not reach the EC2 instances.

Which solutions will resolve this issue? (Choose two.)

  • A. Use AWS Global Accelerator with the existing NLB.
  • B. Create an Amazon CloudFront distribution. Specify the existing NLB as the origin.
  • C. Create a second deployment of the EC2 instances and the NLB in the ap-south-1 Region. Use an Amazon Route 53 latency routing policy to resolve to the Region that provides the least latency.
  • D. Create a second deployment of the EC2 instances and the NLB in the ap-south-1 Region. Use an Amazon Route 53 failover routing policy to resolve to an alternate Region in case packets are dropped.
  • E. Turn on enhanced networking on the EC2 instances by using the most recent Elastic Network Adapter (ENA) drivers.

Question is in multi region Unites States and South Asia this is why C is correct The Amazon Route 53 latency routing policy is used when you have resources in multiple AWS Regions vs Amazon Route 53 failover routing policy is used when you want to configure active-passive failover
