Exam question from Amazon's ANS-C00

Question #: 371
Topic #: 1

A company hosts its application, example.com, behind Application Load Balancers in the us-east-1 and eu-west-1 Regions. Users should be routed to the resources geographically nearest to them. Users must not be routed to the application when it is considered unhealthy.
How should a network engineer configure Amazon Route 53 to route clients to example.com?

A. Configure latency.example.com to use a weighted routing policy that points to the load balancers, and associate an HTTP health check. Configure failover records for example.com. Point the primary alias record to latency.example.com, and enable the evaluate target health setting. Point the secondary record to a static HTML maintenance page hosted in Amazon S3.
B. Configure latency.example.com CNAME latency-based records that point to the load balancers, and associate an HTTP health check. Configure failover records for example.com. Point the primary alias record to latency.example.com, and enable the setting used to evaluate target health. Point the secondary record to a static HTML maintenance page hosted in Amazon S3.
C. Configure latency.example.com to use a geoproximity routing policy that points to the load balancers, and associate an HTTP health check. Configure failover records for example com. Point the primary alias record to latency.example.com, and enable the evaluate target health setting. Point the secondary record to a static HTML maintenance page hosted in Amazon S3.
D. Configure latency.example.com alias latency-based records that point to the load balancers, enable the setting used to evaluate target health, and associate an HTTP health check. Configure failover records for example.com. Point the primary CNAME record to latency.example.com, and associate an HTTP health check. Point the secondary record to a static HTML maintenance page hosted in Amazon S3.

Answer is C. A,B and D mention latency and that's not relevant to the question. R53 allows to route traffic based on the location of the query. There are two types of location based policy. Geolocation: routes traffic according to the querylocation, if there's no rule for that location traffic cannot be routed. Geoproximity: Allows to route traffic according to query location, optionally you can define a default route if no specific rule for the location is defined. https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-policy.html
