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.

  • Review the execution role associated with the serverless function for possible misconfigurations or insufficient permissions leading to latency.

  • Inspect network configurations, since a misconfiguration in network ACLs or security groups might lead to increased response times.

  • Check for any recent updates to the SDK in the serverless function that could be incompatible with the managed database communication protocols.
