AWS Certified Developer Associate DVA-C02 Practice Question
After the deployment of a new feature, your web application starts experiencing unpredictable delays. During peak hours, the system struggles to maintain optimal performance. To address the issue, you consult the service map from AWS X-Ray and notice increased latency in the communication between a serverless computing service and a managed relational database. What should this observation prompt you to investigate further?
Analyze the performance of the managed database, checking for suboptimal queries or resource limitations, and consider enhancements or scaling.
Check for any recent updates to the SDK in the serverless function that could be incompatible with the managed database communication protocols.
Inspect network configurations, since a misconfiguration in network Access Control Lists (ACLs) or security groups might lead to increased response times.
Review the execution role associated with the serverless function for possible misconfigurations or insufficient permissions leading to latency.
