AWS Certified Solutions Architect - Professional SAP-C02 — Topic 1 Question 442

Question

A solutions architect has deployed a web application that serves users across two AWS Regions under a custom domain. The application uses Amazon Route 53 latency-based routing. The solutions architect has associated weighted record sets with a pair of web servers in separate Availability Zones for each Region. The solutions architect runs a disaster recovery scenario. When all the web servers in one Region are stopped, Route 53 does not automatically redirect users to the other Region. Which of the following are possible root causes of this issue? (Choose two.)

Accepted Answer

Correct answer: D, E. The correct answer is D, E. Option D: The setting to evaluate target health is not turned on for the latency alias resource record set that is associated with the domain in the Region where the web servers were stopped. Option E: An HTTP health check has not been set up for one or more of the weighted resource record sets associated with the stopped web servers. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
