A. AWS Trusted Advisor
B. Cost Explorer
C. Amazon Forecast
D. Amazon CloudWatch

**Answer:** The AWS service that provides information about the monthly costs of using Amazon EC2 and Amazon RDS for the past year is:

**B. Cost Explorer**

**Explanation:**
AWS Cost Explorer is a service that allows you to visualize and understand your AWS cost and usage over time. It provides various features and tools for analyzing your AWS spending, including the ability to view historical cost and usage data, identify trends, create custom cost reports, and forecast future costs. This service can help you review your monthly costs for various AWS resources, including EC2 and RDS instances, and make informed decisions about your AWS spending.

Why other options are not correct?

**A. AWS Trusted Advisor:**
– AWS Trusted Advisor is a service that provides recommendations to optimize your AWS environment for cost savings, security, performance, and fault tolerance.
– While it can offer cost-saving recommendations, it doesn’t provide historical cost data or the ability to review past costs over a year.

**C. Amazon Forecast:**
– Amazon Forecast is a service for time-series forecasting and predicting future data trends, such as sales or demand forecasts.
– It’s not designed for retrospective analysis of historical costs.

**D. Amazon CloudWatch:**
– Amazon CloudWatch is a monitoring and observability service that collects and tracks metrics, logs, and events from various AWS resources.
– While it can provide real-time metrics and logs related to EC2 and RDS instances, it doesn’t offer historical cost analysis for the past year.
