Which AWS services or tools can be used to send a notification when AWS costs exceed a specified threshold? (Choose two.)

AWS Budgets allows you to set custom budgets that alert you when your costs or usage exceed (or are forecasted to exceed) your budgeted amount. You can configure notifications to be sent via Amazon SNS topics or directly to email addresses. Amazon CloudWatch can be used in conjunction with AWS Budgets to create alarms that trigger notifications when specific cost metrics (published by AWS Budgets) cross a defined threshold. Amazon SQS is a message queuing service, not directly used for cost notifications. Cost Explorer is a visualization tool for analyzing costs, not for sending proactive alerts. The AWS Cost and Usage Report provides detailed cost data but does not send real-time notifications based on thresholds.
