Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 442 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 442
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

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.)

  • A. The weight for the Region where the web servers were stopped is higher than the weight for the other Region.
  • B. One of the web servers in the secondary Region did not pass its HTTP health check.
  • C. Latency resource record sets cannot be used in combination with weighted resource record sets.
  • 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.
  • 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.

D. The "Evaluate Target Health" setting is not enabled for the latency alias record set associated with the stopped Region. When using latency routing, this setting must be enabled so Route 53 considers the health status of associated resources and stops routing traffic to unavailable servers. E. HTTP health checks are not set up for one or more weighted record sets associated with the stopped web servers. Without health checks, Route 53 cannot detect unhealthy or unavailable servers and will continue routing traffic to them.

Selected Answer: DE
Route 53 latency-based routing does not inherently perform health checks. If a web server in one region goes down, Route 53 won't automatically redirect traffic to the other region unless health checks are properly configured and associated with your DNS records.
