AWS Certified Developer Associate DVA-C02 Practice Question

Activating tracing services for the serverless function is critical, providing insight into execution behavior and identifying performance bottlenecks. Once tracing is enabled, the detailed data gathered allows for a precise analysis of the function's interactions, helping to uncover inefficiencies. This step is foundational before proceeding to optimize, as it ensures that changes are data driven rather than assumptions based.

Boosting the memory allocation might ameliorate latency, however, without preliminary analysis, this action may not tackle the root cause. Similarly, component decoupling with a message queuing service is an optimization that should come after performance insights are attained. Introducing a caching mechanism could improve responsiveness, but it may not be directly linked to the serverless function's intrinsic performance concerns.
