Which component of AWS infrastructure can the company use to meet this requirement?

Explanations:

A content delivery network (CDN), such as Amazon CloudFront, helps with distributing content globally but does not directly enhance the application’s resilience by itself.

Edge locations are part of a CDN’s infrastructure, used to cache content close to end users. While they improve performance, they do not provide high resilience for an application.

Wavelength Zones are used to extend AWS services to 5G networks at the edge, improving latency for mobile applications but not directly enhancing general application resilience.

Availability Zones are distinct physical locations within a region designed for high availability and resilience. Distributing an application across multiple Availability Zones ensures redundancy and fault tolerance.
