D " Cost Explorer" Key word "based on past consumption"

Answer is D. Cost explorer https://docs.aws.amazon.com/cost-management/latest/userguide/ce-forecast.html

AWS cost explorer is used for this purpose. Amazon forecast has different use case.

A. AWS Cost and Usage Report Explanation: The AWS Cost and Usage Report provides detailed information about costs and usage for a specified period. It includes the historical data necessary for forecasting future costs and usage based on past consumption. Users can analyze the report to understand spending patterns and estimate future costs. Options B, C, and D serve different purposes: Amazon Forecast (Option B): A service that uses machine learning to generate accurate time-series forecasts. AWS Pricing Calculator (Option C): A tool for estimating the cost of AWS services based on selected configurations, not designed for forecasting past usage. Cost Explorer (Option D): A tool within the AWS Management Console that provides visualizations of cost and usage data, but it is not intended for forecasting future costs based on past consumption.

To forecast future costs and usage of AWS resources based on past consumption, the most appropriate AWS service or tool is: B. Amazon Forecast Amazon Forecast is a machine learning service provided by AWS that is specifically designed for generating accurate time-series forecasts. It can be used to forecast future AWS resource usage and costs based on historical data. The other options, while related to AWS cost management and reporting, do not offer the same predictive forecasting capabilities: A. AWS Cost and Usage Report: This provides detailed information on your past AWS costs and usage but doesn't offer future forecasting. C. AWS Pricing Calculator: This tool helps estimate costs for AWS services, but it doesn't provide future usage and cost forecasting. D. Cost Explorer: It's a component of AWS Cost Explorer that helps you analyze your past AWS costs and usage, but it doesn't provide future forecasting on its own.

Amazon Forecast is a machine learning service that can be used to forecast future costs and usage of AWS resources based on past consumption. It uses historical data to train a model that can predict future trends.

Amazon Forecast is a fully managed service that uses statistical and machine learning algorithms to deliver highly accurate time-series forecasts. Based on the same technology used for time-series forecasting at Amazon.com, Forecast provides state-of-the-art algorithms to predict future time-series data based on historical data, and requires no machine learning experience.

AWS Pricing Calculator does not forecast based on past usage. After you enable Cost Explorer, AWS prepares the data about your costs for the current month and the last 12 months, and then calculates the forecast for the next 12 months. https://aws.amazon.com/aws-cost-management/aws-cost-explorer/

AWS Pricing Calculator is used to estimate the costs of AWS services before actually deploying them. It is not designed for ongoing cost and usage forecasting based on historical data like AWS Cost Explorer. So the answer is D.

D. Cost Explorer: AWS Cost Explorer provides cost and usage reporting and analysis. It includes a forecasting feature that uses historical data to project future costs and usage. This allows you to estimate and plan for future spending based on your past consumption patterns. By using Cost Explorer, you can gain insights into your AWS resource usage and costs, analyze trends, and make informed decisions about optimizing your infrastructure and budge

D " Cost Explorer" https://docs.aws.amazon.com/cost-management/latest/userguide/ce-forecast.html "A forecast is a prediction of how much you will use AWS services over the forecast time period that you selected. This forecast is based on your past usage. You can use a forecast to estimate your AWS bill and set alarms and budgets for based on predictions. Because forecasts are predictions, the forecasted billing amounts are estimated and might differ from your actual charges for each statement period."

AWS Cost and Usage Report is a more detailed version of Cost Explorer. Why would this be incorrect?

the correct option for forecasting future costs and usage based on past consumption is D. Cost Explorer.

while Amazon Forecast is designed to create forecasts based on historical data, it is not specifically designed to provide cost management and optimization tools, including forecasting of future costs and usage of AWS resources based on past consumption. This is the primary function of AWS Cost Explorer, which is specifically designed to help customers visualize, understand, and manage their AWS costs and usage over time.

D is the answer.

D is correct answer in 2022
