AWS Cloud Practitioner CLF-C02 Practice Question

Choosing an AWS Region that is geographically closer to your end-users is the most effective way to reduce latency. An AWS Region is a separate geographic area, and deploying resources in a European region ensures that data travels a shorter physical distance to users in Europe. In contrast, adding more Availability Zones within the current Region improves high availability and fault tolerance but does not reduce latency for users on a different continent, as all AZs within a region are in the same general geographic area. AWS Wavelength is for ultra-low latency applications on 5G networks, and one in the US would increase latency for European users. Amazon AppStream is an application streaming service and is not designed for general application latency reduction based on geography.
