AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 223

You are a network admin of a US company called Webby Widgets that is expanding to Europe. The company has a website that serves dynamic and static content.
You have been instructed to ensure the European clients receive the least latency possible, no matter where in Europe they live, while still allowing the US clients to receive the same user experience and performance they have been accustomed to. You have also been instructed to ensure both countries use the same URL to access the site and keep costs low.
What two things should you do? (Choose two.)

Answer options

• A. Deploy three VPCs; one for the US, one for the EU, and one as a central VPC that hosts an Elastic Load Balancer that will distribute traffic between the US and EU VPCs.
• B. Create two A records: eu.webbywidgets.com that points to the EU resources and us.webbywidgets.com that points to the US resources.
• C. Use the Traffic Flow policy creator to create the perfect routing policy.
• D. Create a CloudFront distribution to serve the static content from an S3 bucket.

Correct answer: C, D

Explanation

The correct answers are C and D because using the Traffic Flow policy allows for intelligent routing to minimize latency for users across different regions, while a CloudFront distribution ensures that static content is served efficiently from the nearest edge location. Options A and B do not address the need for unified URL access and increased performance, making them less effective solutions for the scenario presented.
