Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 404 discussion

1. Ensures all important user interactions and transactions are traced (by disabling sampling for these). 2. Reduces the sampling rate for high-volume background tasks, which helps avoid wasting resources on less important requests.

D. Sampling for user requests - transactions and and interactions and disable tracing healthckes and so on. X-Ray answears for the question asked by user "why it took it so long?" C is not correct answear, because recording ALL requests (even low-volume requests) is overwhelming for the system

C: trace everything, not sample it.

It’s C

D is correct Chatgpt explanation Focus on Important Traces: By disabling sampling for high-volume read-only requests such as health checks, polling, and connection maintenance, you can prevent these low-priority requests from overwhelming the tracing system. This ensures that the system resources are conserved for more critical user interactions and transactions. Higher Sampling Rate for User Interactions: By sampling at a higher rate for requests that handle user interactions or transactions, you can ensure that these important requests are traced more comprehensively. This allows for better monitoring and troubleshooting of the application where it matters most. Selective Tracing: This approach allows you to selectively trace and monitor requests based on their importance and volume. High-volume background tasks are sampled minimally or not at all, while low-volume but critical user interactions and transactions are sampled more frequently.
