Practice Test 2 | AWS Certified Solutions Architect Associate | SAA-C03 | Dumps | Mock Test
You are working as an AWS Architect for a start-up company. The company has web-servers deployed in all AZ’s in eu-central-1 (Frankfurt) region. These web servers serve German news & local web content for people accessing these websites within Germany. These web servers have multiple records created for a single domain. Company is looking for a random selection of web-servers that will increase the availability. What would be the most appropriate routing policy for this requirement?
A. Latency routing policy
B. Weighted routing policy
C. Multivalue answer routing policy
D. Geolocation routing policy
Explanation:
Correct Answer – C
When Route 53 is configured with Multi-value answer routing, it returns multiple values for web-servers. Route 53 responds to DNS queries with up to eight healthy records and traffic is approximately load-balanced between these multiple web-servers.
Option A is incorrect. Latency routing policy is used when multiple resources are mapped with single domain & resource with the best latency to the resource is provided. Since most of the times these servers will be accessing locally from the German region, latency to the web servers will be approximately the same.
Option B is incorrect. Weighted routing policy is used when multiple resources are mapped with a single domain & you need to route traffic in a weighted proportionate to each resource. As in this case, the requirement is to use all web servers randomly, the weighted routing policy will not be an ideal option.
Option D is incorrect as Geolocation routing policy is used to choose resources based upon the user’s location. In this case, all users will be Germany-based & so there would not be random selection on the resource.
