Answers
D.
Use Region annotation that X-Ray adds automatically for user-defined services Configure X-Ray to add Region annotation for AWS services
Suggested answer: B

Explanation:

Distributed Tracing with X-Ray:X-Ray helps visualize request paths and identify bottlenecks in applications distributed across Regions.

Region Annotations (Automatic for AWS Services):X-Ray automatically adds a Region annotation to segments representing calls to AWS services. This aids in tracing cross-Region traffic.

Region Annotations (Manual for User-Defined):For segments representing calls to user-defined services in different Regions, the developer needs to add the Region annotation manually to enable comprehensive tracing.
