SOA-C03 practice question: Route 53 routing and Resolver (2 of 2)
Networking and Content Delivery A free question from our original SOA-C03 practice exam. Try it, then open the answer to see why each option is right or wrong.
A pet insurer serves policyholders in the United Kingdom and the United States from two copies of its portal, one in eu-west-2 and one in us-east-1. A data-residency rule says UK users must always be sent to eu-west-2, even when us-east-1 would respond faster. All other users, including those in countries the company has not planned for, should go to us-east-1. Which Route 53 configuration should a CloudOps engineer use?
Choose one answer.
- AA. Geolocation records: United Kingdom to eu-west-2, plus a default location record to us-east-1.
- BB. Latency-based records for the two Regions so that each user is sent to the Region with the lowest latency.
- CC. Weighted records with a weight of 50 for each Region so that traffic is split evenly between the two portals.
- DD. Geoproximity records with a positive bias on eu-west-2 so that more of Europe is routed to the UK portal.
Show the answer and explanation
Answer: A
Explanation
When a legal rule ties users in a country to a Region, geolocation routing is the right policy, because it answers by the user's location. A default record covers locations with no specific record, so no user gets an empty answer. Latency, weighted and geoproximity routing all decide by other factors.
