DynamoDB - Cost Optimization and MonitoringWhich JSON snippet correctly configures a monthly budget alert for DynamoDB usage at $200?A{ "BudgetLimit": 200, "Notification": { "Threshold": 110, "Type": "FORECASTED" } }B{ "BudgetLimit": 200, "Notification": { "Threshold": 90, "Type": "ACTUAL" } }C{ "BudgetLimit": 200, "Notification": { "Threshold": 50, "Type": "ACTUAL" } }D{ "BudgetLimit": 200, "Notification": { "Threshold": 200, "Type": "ACTUAL" } }Check Answer
Step-by-Step SolutionSolution:Step 1: Understand BudgetLimitThe budget limit is set to $200, which matches the requirement.Step 2: Check Notification ThresholdThreshold at 90 means alert triggers at 90% of $200 = $180, which is a common alert point.Step 3: Confirm Notification TypeType 'ACTUAL' means alert triggers on actual spending, suitable for monitoring real costs.Final Answer:{ "BudgetLimit": 200, "Notification": { "Threshold": 90, "Type": "ACTUAL" } } -> Option BQuick Check:Threshold under 100% and ACTUAL type alert [OK]Quick Trick: Set threshold below 100% and use ACTUAL type [OK]Common Mistakes:MISTAKESSetting threshold above 100% (won't trigger early alerts)Using FORECASTED type when ACTUAL is neededSetting threshold too low causing frequent alerts
