Task 4.2: Understand resources for billing, budget, and cost management.

• AAWS Budgets

  Correct

  A cost budget can alert on forecasted spend as well as actual spend, by email or through an Amazon SNS topic.

• BAWS Cost Explorer

  Incorrect

  Cost Explorer is for viewing and analyzing costs and usage, including a forecast. Sending an alert at a threshold is what a budget does.

• CAWS Pricing Calculator

  Incorrect

  The Pricing Calculator estimates the cost of a planned workload. It does not watch what an account is actually spending.

• DAWS Trusted Advisor

  Incorrect

  Trusted Advisor recommends ways to save money and close gaps; it does not alert on a spending threshold you set.

Budgets watch spend against a number you choose and tell you before or after you cross it. Cost Explorer explains where the money went.

• AAWS Pricing Calculator

  Incorrect

  The Pricing Calculator creates cost estimates for planning. It has nothing to do with how accounts are billed.

• BAWS Budgets

  Incorrect

  Budgets track costs and usage against a target and send alerts. They do not merge the bills of several accounts.

• CConsolidated billing

  Correct

  Consolidated billing gives one bill for multiple accounts, lets you track each account's charges, combines usage for volume discounts, and costs nothing extra.

• DAWS Artifact

  Incorrect

  Artifact provides AWS compliance documents and agreements, not billing.

One payer, many accounts: the management account of an organization pays the charges of every member account, and each account's costs stay visible.

• AAWS Pricing Calculator

  Incorrect

  The Pricing Calculator estimates the cost of planned workloads. It does not show what an account has actually spent.

• BAWS Budgets

  Incorrect

  Budgets track spending against a target you set and send alerts. The exploring and charting of past costs is Cost Explorer's job.

• CAWS Trusted Advisor

  Incorrect

  Trusted Advisor recommends ways to save money, but it is not a tool for analyzing spending history.

• DAWS Cost Explorer

  Correct

  Cost Explorer lets you view and analyze your costs and usage over time, filter and group them, for example by service, and forecast future costs.

Looking back and forecasting: Cost Explorer. Setting a limit and being alerted: Budgets. Estimating before you build: Pricing Calculator.

• AAWS Pricing Calculator

  Correct

  The Pricing Calculator is a planning tool for creating cost estimates of AWS use cases before you build them.

• BAWS Cost Explorer

  Incorrect

  Cost Explorer analyzes the costs an account has already incurred, and forecasts from them. There is nothing to analyze yet.

• CAWS Budgets

  Incorrect

  Budgets watch actual and forecasted spend against a target. They do not price an architecture that does not exist yet.

• DConsolidated billing in AWS Organizations

  Incorrect

  Consolidated billing combines the bills of several accounts. It does not estimate future costs.

Estimates come before the account spends anything; Cost Explorer and Budgets work on what it has spent and is spending.

• ACreate a separate VPC for each project's resources

  Incorrect

  A VPC is a virtual network. Splitting networks does not make costs appear by project in billing reports.

• BTurn on AWS CloudTrail

  Incorrect

  CloudTrail records API activity for auditing. It does not organize costs.

• CDownload reports from AWS Artifact

  Incorrect

  Artifact provides AWS's compliance reports, not the company's cost data.

• DActivate "project" as a cost allocation tag

  Correct

  User-defined tags must be activated as cost allocation tags before they appear in Cost Explorer or on a cost allocation report, which then groups costs by the tag.

Tags organize resources; activated cost allocation tags organize the bill. Only after activation do they show up in cost reports.
