AWS Certified Solutions Architect Professional SAP-C02 Practice Question
A company has 20 AWS member accounts that are linked to a management account by AWS Organizations. Each account hosts multiple workloads that are owned by different internal teams. Finance must:
Generate a monthly chargeback report that shows the AWS cost for every team.
Roll the cost of any untagged resources into a bucket named "NoOwner" so that Finance can spot tagging gaps.
View a cost forecast for the next three months.
Receive an automated email when a team's monthly spend is forecasted to exceed its budget by more than 10 percent.
The cloud architect wants to meet these requirements with the least operational overhead while using only native AWS services.
Which combination of actions meets the requirements?
Enable the AWS Cost and Usage Report (CUR) for each member account. Deliver CUR files to Amazon S3, run scheduled Amazon Athena queries that group costs by the "Team" tag, and visualize the results in Amazon QuickSight. Use Amazon CloudWatch alarms on Athena query results to send email alerts when spend exceeds 110 % of budget.
Enable AWS Cost Anomaly Detection and create a monitor for every account. Use AWS Compute Optimizer to project future costs and configure a single AWS Budget that sends alerts when the organization's unblended cost exceeds 10 % of the previous month.
Activate a "Team" cost allocation tag in the management account. Create an AWS Cost Category that inherits the tag and assigns a default value such as "NoOwner" for unmatched resources. In AWS Cost Explorer, build a monthly report grouped by the cost category and enable a three-month forecast. Create an AWS cost budget for each cost-category value with a forecasted threshold of 110 % and configure an email alert.
Create a billing group for each team in AWS Billing Conductor. Use AWS Pricing Calculator to estimate quarterly spend for each billing group and configure Amazon EventBridge rules that send SNS email notifications when actual account-level spend in AWS Cost Explorer exceeds the estimate by 10 %.
The simplest native-service approach is to rely on the AWS cost-management stack that is already integrated with AWS billing data.
Activate a user-defined cost allocation tag such as "Team" in the management account so that the tag becomes visible in billing data. Activating the tag is required before it can be used for reporting.
Create an AWS Cost Category that inherits the Team tag and sets a default value (for example, NoOwner) for all line items that do not contain the tag. This automatically groups both tagged and untagged spend without any external processing.
Use AWS Cost Explorer to build a monthly view that is grouped by the new cost-category values. Cost Explorer can also display a forecast of up to 12 months, which covers the next quarter and requires no additional setup.
For each cost-category value, create an AWS Budget that has a forecasted alert threshold of 110 % (10 % over the team's budgeted amount). Configure the budget to send email (or SNS) notifications when the threshold is crossed.
This solution meets every requirement, is entirely managed by AWS, and avoids the data-pipeline maintenance associated with exporting and querying the Cost and Usage Report or building custom dashboards. The other options either require significantly more operational work (for example, CUR + Athena + QuickSight), do not identify untagged resources, or use services that do not provide the required forecasting and alerting capabilities.
