DynamoDB - Cost Optimization and Monitoring

You wrote this alert rule but never got notified despite high usage:

{
  "BudgetLimit": 50,
  "Notification": {
    "Threshold": 80,
    "Type": "ACTUAL"
  }
}

What is the likely error?

AMissing alert email address configuration.

BThreshold should be a percentage, not a number.

CNotification type "ACTUAL" is invalid.

DBudgetLimit must be in cents, not dollars.

Step-by-Step Solution

Solution:

Step 1: Analyze the provided alert rule JSON
The snippet includes BudgetLimit, Threshold (80% correctly as number), and ACTUAL type, but omits Subscribers configuration.
Step 2: Recall AWS Budgets notification requirements
Notifications require specifying recipients like email or SNS topics; without them, no alerts are sent even if thresholds are met.
Final Answer:
Missing alert email address configuration. -> Option A
Quick Check:
Missing subscribers = no notification [OK]

Quick Trick: Budget notifications require email/SNS subscriber config [OK]
