AWS Certified Developer Associate DVA-C02 Practice Question
Your company's new web application has just been deployed to production, and you're tasked with setting up its operational backbone. You need to prepare the application for incident response and ensure that you have adequate visibility into the system's performance and behavior. Which approach aligns best with your goal of full system observability?
Setting up a comprehensive system of structured logs, detailed metrics, and distributed tracing.
Caching frequently accessed data to optimize read times.
Creating a detailed metrics dashboard that displays the CPU and memory usage of your application environments.
Configuring alerts to notify the team upon encountering any HTTP 5XX errors.
Implementing a comprehensive strategy that incorporates structured logs, detailed metrics, and distributed tracing provides full observability into the application's health and performance. Structured logs allow capturing consistent and context-rich logging data, detailed metrics offer quantitative information about the system's operation, and distributed tracing enables tracking of individual requests as they flow through the system, linking the metrics and logs to provide a complete picture of the application's behavior. Caching data optimizes read times but doesn't contribute to observability. Similarly, setting up a single metrics dashboard provides a view but not in-depth tracking of individual requests. Configuring alerts for errors ensures an incident response but does not facilitate ongoing analysis of system performance and behavior.
