  4. D
    They are geographic areas that define data sovereignty and compliance boundaries.
  5. E
    They are used to host primary database instances to ensure application high availability.

Answer

AWS Edge Locations are used by Amazon CloudFront to cache content closer to end users, helping to reduce latency for global users by delivering content from nearby sites.
The correct answers state that Edge Locations are used by Amazon CloudFront to cache content closer to end users and that they help reduce latency for global users by delivering content from nearby sites. These two characteristics define the fundamental role of Edge Locations within the AWS Global Infrastructure.

Step-by-Step Solution

1
Identify the primary purpose of AWS Edge Locations.
Edge Locations are cache endpoints used by Amazon CloudFront to store copies of files closer to global users.
This allows requests to be served from the nearest location rather than fetching them from the origin server every time.
2
Analyze each option to see if it describes AWS Edge Locations or another AWS infrastructure component.
The options describing Amazon CloudFront caching and reducing latency for global users are correct. The options describing isolated data centers, data sovereignty boundaries, and hosting database instances describe Availability Zones and AWS Regions.
This filters out the incorrect infrastructure roles (Regions and Availability Zones) and confirms the correct characteristics of Edge Locations.
