Your question is Debugging with CloudWatch. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Log in to an environment and debug a problem: use CloudWatch logs to debug a database connection issue (root cause: DB config allowed too few connections).
Asked in the onsite stage. Explain your investigation as you work, identify the root cause from the available evidence, and describe the safest corrective action and validation steps.
