CLF-C02 Billing, Pricing, and Support Practice Test 3 — 15 Questions

Question 1

A company runs a production application on a mix of Amazon EC2 instance families (e.g., M5, C5, R5) across two AWS Regions. The application runs 24/7 and is expected to continue for the next three years. The company wants to minimize compute costs while retaining the flexibility to change instance families, sizes, or Regions if needed. The company also prefers to avoid any upfront payment to preserve cash flow. Which AWS pricing option should the company choose?

Accepted Answer

Compute Savings Plans (no upfront, 3-year term). Compute Savings Plans (no upfront, 3-year term) provide the highest discount (up to 66%) while allowing flexibility to change instance families (e.g., M5 to C5), sizes, and AWS Regions. This matches the company’s requirement to minimize costs over three years without upfront payment, and the plan automatically applies to any EC2 instance usage within the chosen commitment, preserving the ability to switch instance types or Regions as needed.

Question 2

A company has been using Amazon EC2 instances for a production application for the past 12 months. The finance team wants to understand historical spending patterns and identify opportunities to reduce costs. Specifically, they need to see which EC2 instance families and sizes are being underutilized and get recommendations for purchasing Reserved Instances to save money compared to current On-Demand pricing. The team wants to use a native AWS tool that provides a visual dashboard of costs, usage trends, and actionable recommendations. Which AWS tool should the finance team use?

Accepted Answer

AWS Cost Explorer. AWS Cost Explorer is the correct choice because it provides a visual dashboard of historical cost and usage data, including the ability to filter by EC2 instance families and sizes to identify underutilized resources. It also offers Reserved Instance (RI) purchase recommendations based on historical On-Demand usage, enabling the finance team to compare costs and identify savings opportunities directly within the native AWS console.

Question 3

A company uses AWS Organizations with multiple accounts for different departments (Engineering, Marketing, Sales). The finance team needs to create detailed monthly chargeback reports showing each department's usage and costs, broken down by service (e.g., Amazon EC2, Amazon S3) and by custom tags (e.g., Project). The reports must be in a machine-readable format (CSV) so they can be ingested into the company's internal billing system. The team wants the most comprehensive, granular cost data available from AWS, including line items for individual resources. Which AWS tool should the finance team configure to meet these requirements?

Accepted Answer

AWS Cost and Usage Report. The AWS Cost and Usage Report (CUR) is the correct choice because it provides the most comprehensive, granular cost data available, including line items for individual resources broken down by service, custom tags, and time period. It can be delivered to an Amazon S3 bucket in CSV format, which is machine-readable and suitable for ingestion into the company's internal billing system for detailed monthly chargeback reports.

Question 4

A company operates a critical e-commerce platform on AWS that generates significant revenue. The management team requires a dedicated Technical Account Manager (TAM) to provide proactive guidance and operational best practices. Additionally, they need the fastest possible response time for critical system failures, targeting a response within 15 minutes. Which AWS Support plan should the company choose?

Accepted Answer

Enterprise Support. The company requires a dedicated Technical Account Manager (TAM) and the fastest possible response time for critical system failures (15-minute response). Only the Enterprise Support plan includes a designated TAM and provides a 15-minute response time for business-critical system failures. The Enterprise On-Ramp Support plan offers a TAM but has a longer 30-minute response time for critical cases, and the Business Support plan does not include a TAM at all.

Question 5

A company runs a production web application that uses Amazon EC2 instances, AWS Lambda functions, and Amazon ECS tasks. The application runs 24/7 and the company expects steady usage for the next three years. The company wants to commit to a flexible pricing model that provides significant discounts compared to On-Demand and automatically applies to usage across all three compute services. The company also wants the flexibility to change instance families, regions, or even migrate between compute services (e.g., from EC2 to Lambda) without needing to modify the commitment. Which AWS pricing model should the company choose?

Accepted Answer

Compute Savings Plans. Compute Savings Plans offer the required flexibility: they automatically apply to EC2 instances, Lambda functions, and ECS Fargate usage, provide significant discounts (up to 66%) compared to On-Demand, and allow changes to instance families, regions, or compute services without modifying the commitment. This model is ideal for steady 24/7 workloads over a three-year term, as it combines broad compute coverage with automatic discount application.

Question 6

A company runs a production web application on Amazon EC2 and Amazon RDS. The internal IT team needs a support plan that provides a guaranteed response time of less than one hour for a production system outage. Additionally, the company wants access to AWS Infrastructure Event Management, which includes guidance from AWS experts during planned events such as product launches or migrations. The company does not require a dedicated Technical Account Manager (TAM). Which AWS Support plan should the company choose?

Accepted Answer

Business Support. The Business Support plan is the correct choice because it provides a guaranteed response time of less than one hour for production system outages (production system impaired) and includes access to AWS Infrastructure Event Management for guidance during planned events. The company does not need a dedicated Technical Account Manager (TAM), which is only available with the Enterprise Support plan, making Business Support the most cost-effective option that meets all stated requirements.

Question 7

A startup is planning to migrate its web application to AWS. The CTO wants to estimate the monthly cost of running the application on Amazon EC2 and Amazon RDS, including data transfer costs. The team has not yet created any AWS accounts or resources. They need a tool that allows them to input assumptions about instance types, storage, and data transfer to generate a detailed cost estimate. Which AWS tool should they use?

Accepted Answer

AWS Pricing Calculator. AWS Pricing Calculator (option C) is the correct tool because it allows users to input assumptions about EC2 instance types, RDS configurations, storage, and data transfer to generate a detailed monthly cost estimate before any AWS resources are created. Unlike Cost Explorer, which requires existing usage data, the Pricing Calculator is designed for upfront cost modeling and planning.
