CLF-C02 Billing, Pricing, and Support Practice Test 9 — 15 Questions

Question 1

A company is planning to migrate a legacy application to AWS. The solutions architect needs to estimate the monthly cost of running Amazon EC2 instances, Amazon RDS databases, and Amazon S3 storage. The architect wants to compare different instance types, storage classes, and pricing models (e.g., On-Demand vs. Reserved Instances) to find the most cost-effective configuration. The team requires a tool that provides a detailed, itemized cost estimate without incurring any actual charges, and allows saving and sharing the estimate with stakeholders. Which AWS tool should the solutions architect use?

Question 2

A company runs several applications in a single AWS account. Each application belongs to a different project (Project Alpha, Project Beta, Project Gamma). The company has already applied tags with the key "Project" and the corresponding project name to all AWS resources used by each project. The finance team wants to use AWS Cost Explorer to view and filter monthly costs by project. However, after tagging all resources, the "Project" tag does not appear as a filter option in Cost Explorer. What must the finance team do to make the "Project" tag available for cost filtering in Cost Explorer?

Accepted Answer

Activate the "Project" cost allocation tag in the Billing and Cost Management console.. The 'Project' tag does not appear in Cost Explorer because AWS does not automatically activate user-defined tags for cost tracking. The finance team must manually activate the 'Project' cost allocation tag in the Billing and Cost Management console under 'Cost Allocation Tags'. Once activated, AWS will process the tag data and make it available as a filter in Cost Explorer within 24 hours.

Answer

Create a new AWS Budget with a cost filter for the "Project" tag.

Answer

Enable the AWS Cost and Usage Reports for the account.

Answer

Create a custom cost category with a rule that uses the "Project" tag.

Question 3

A company uses AWS for its development environment. The finance team wants to set a monthly budget of $10,000. They want to receive an email notification when the actual costs reach 80% of the budget ($8,000) and again when costs exceed the budget. The team needs a managed AWS service that can automatically send these alerts without requiring custom code or third-party tools. Which AWS service should the team use?

Accepted Answer

AWS Budgets. AWS Budgets is a managed service that allows you to set custom cost and usage budgets and receive alerts when your actual or forecasted costs exceed (or are forecasted to exceed) your budgeted amount. It can automatically send email notifications at specified thresholds (e.g., 80% and 100%) without requiring any custom code or third-party tools, making it the ideal solution for the finance team's requirements.

Question 5

A company operates in three separate AWS accounts: one for development, one for testing, and one for production. The company wants to take advantage of volume pricing discounts across all accounts for services such as Amazon S3 and Amazon EC2. The finance team also wants to view a single, consolidated monthly bill that aggregates charges from all accounts. Which AWS feature should the company implement?

Accepted Answer

AWS Organizations with consolidated billing. AWS Organizations with consolidated billing is the correct feature because it allows the company to combine all three AWS accounts (development, testing, production) into a single organization, enabling volume pricing discounts across accounts for services like Amazon S3 and Amazon EC2. It also aggregates usage from all accounts into a single monthly bill, which the finance team can view. This is the only AWS feature that directly provides both consolidated billing and aggregated usage for pricing benefits.

Question 13

A company uses AWS for multiple projects. Each project's resources have been tagged with 'Project' and 'Team' tags. The finance team wants to view a cost breakdown in AWS Cost Explorer using these tags. The tags are already applied to existing resources. However, when the finance team opens Cost Explorer, the tags are not available for filtering. What must the finance team do to see costs by these tags?

Accepted Answer

Activate the cost allocation tags in the Billing and Cost Management console.. Cost allocation tags must be explicitly activated in the Billing and Cost Management console before they appear in AWS Cost Explorer. Even though tags are already applied to resources, AWS does not automatically make them available for cost filtering until they are activated as cost allocation tags. This activation process enables the tags to be recognized by billing and cost management services.

Answer

Enable detailed billing reports in the Billing console.

Answer

Create a budget in AWS Budgets and set tag-based filters.

Answer

Use AWS Organizations to create separate accounts per project.

Question 14
