CLF-C02 Billing, Pricing, and Support Practice Test 13 — 15 Questions

Question 1

Which AWS feature provides personalized recommendations about your account's security and cost optimization, available at no cost for all AWS customers?

Accepted Answer

AWS Trusted Advisor. AWS Trusted Advisor is the correct answer because it provides personalized recommendations across five categories: cost optimization, performance, security, fault tolerance, and service limits. It is available at no additional cost for all AWS customers, with the basic checks included in the Free Tier and Basic Support plan, while more detailed checks require a Business or Enterprise Support plan.

Answer

Answer

AWS Personal Health Dashboard

Answer

Amazon CloudWatch

Question 2

A company uses AWS Organizations. The management account receives the consolidated bill. Which statement about Reserved Instance discount sharing in AWS Organizations is correct?

Accepted Answer

RI discounts are automatically shared across all member accounts in the organization. In AWS Organizations, Reserved Instance (RI) discounts are automatically shared across all accounts in the organization, provided the accounts are under the same consolidated billing family and the RIs are in the same AWS region. This means that if one member account purchases an RI, the hourly cost benefit can apply to qualifying usage from any other account in the organization, reducing the overall bill. The management account receives the consolidated bill and can see the aggregated savings, but no explicit sharing configuration is required.

Answer

Reserved Instance discounts only apply to the account that purchased the RI

Answer

RI discounts are only shared if the management account explicitly enables sharing for each RI

Answer

RI discounts cannot be shared across accounts even in an Organization

Question 3

A company has committed to a 1-year Compute Savings Plan at $100/hour. During a given hour, their actual compute usage is only worth $80 at On-Demand rates. How does the Savings Plan apply?

Accepted Answer

You pay the committed $100 for the hour, with $20 of the commitment being unused. With a Compute Savings Plan, you commit to a consistent hourly spend ($100/hour) in exchange for lower compute rates. If your actual usage in an hour is only $80 at On-Demand rates, you still pay the full $100 commitment for that hour; the unused $20 is not refunded or carried over. This is because Savings Plans require you to pay the committed amount regardless of actual usage, ensuring AWS receives the predictable revenue that funds the discount.

Answer

You pay $80 (actual usage) and the unused $20 commitment carries over to the next hour

Answer

You are refunded the $20 unused portion at end of month

Answer

You pay $80 discounted at the Savings Plan rate, saving even more than committed

Question 4

Accepted Answer

CUR + Cost Explorer + Budgets + Cost Allocation Tags + Savings Plans. It combines AWS Cost and Usage Reports (CUR) for granular cost data, Cost Explorer for visualization and analysis, Budgets for proactive alerts, Cost Allocation Tags for cost attribution, and Savings Plans for discounted rates. This integrated set provides end-to-end FinOps capabilities—visibility, budgeting, and optimization—that no single service or partial combination can achieve.

Question 5

A company is concerned about unexpected AWS charges from development instances that developers forget to stop. Which AWS service provides a simple dashboard showing AWS service health events and can also be used to stay informed about account-level events?

Accepted Answer

AWS Health Dashboard (Personal Health Dashboard). The AWS Health Dashboard (Personal Health Dashboard) provides a personalized view of the health of AWS services and resources that affect your account, including scheduled maintenance, security notifications, and other account-level events. While it does not directly show billing alerts, it helps you stay informed about service-related events that could impact your resources.

Question 6

A company running large-scale scientific simulations needs EC2 instances with exclusive access to a physical host for software licensing reasons (per-socket licensing). Which EC2 option provides this?

Accepted Answer

Dedicated Hosts. Dedicated Hosts (Option B) provide EC2 instances with exclusive access to a physical host, allowing you to control instance placement on a specific server. This is required for per-socket software licensing because you can see and manage the physical sockets and cores of the host, ensuring compliance with licensing terms that are tied to physical hardware.

Answer

Dedicated Instances

Answer

Reserved Instances

Answer

EC2 Bare Metal instances

Question 7

A company's AWS bill has increased significantly. The finance team wants to implement cost governance best practices. Which action represents a foundational cost governance control?

Accepted Answer

Implement a tagging strategy and enforce tags with AWS Config rules. Implementing a tagging strategy and enforcing tags with AWS Config rules is a foundational cost governance control because it enables cost allocation, tracking, and accountability. Tags allow the finance team to categorize resources by project, environment, or cost center, and AWS Config rules can automatically enforce tag compliance, preventing untagged resources from being launched. This directly supports cost governance by providing visibility and control over spending, which is the first step in optimizing costs.

Answer

Question 8

Which AWS pricing benefit means that the more AWS services you use across your organization, the greater the volume discounts you receive on some services?

Accepted Answer

Tiered volume pricing discounts. Tiered volume pricing discounts reward customers with lower per-unit costs as their usage volume increases across multiple services. This is a built-in AWS pricing model where the more you use, the more you save, without requiring any upfront commitment or reservation.

Answer

Reserved Instance discounts

Answer

Question 9

A company needs an AWS support plan that provides access to online training, use case guidance, and architectural support for non-production environments. Which is the minimum plan that provides direct technical guidance from AWS engineers (not just documentation)?

Accepted Answer

Developer Support. Developer Support is the minimum AWS support plan that provides direct technical guidance from AWS engineers, including online training, use case guidance, and architectural support for non-production environments. Basic Support only offers documentation and community forums, while Business and Enterprise plans include these features but are higher tiers, making Developer the correct minimum.

Question 11

A company is considering AWS for their new application. Which tool allows them to compare the cost of running their workloads on AWS versus on-premises, and estimate the potential savings?

Accepted Answer

AWS Pricing Calculator. AWS Pricing Calculator (formerly TCO Calculator) is specifically designed to compare the cost of running workloads on AWS versus on-premises environments. It allows users to input their current on-premises infrastructure details (such as server specifications, storage, and network usage) and generates a detailed cost comparison, including estimated savings from migrating to AWS. This directly matches the question's requirement for comparing costs and estimating potential savings.

Question 12

Which statement about Amazon EC2 On-Demand pricing is accurate?

Accepted Answer

On-Demand instances are billed per second with no upfront commitment or termination fees. Amazon EC2 On-Demand instances are billed per second (with a minimum of 60 seconds) for Linux instances, and per hour for other operating systems, with no upfront payment or termination fees. This model provides maximum flexibility, allowing you to launch and stop instances as needed without any long-term commitment or penalty.

Answer

On-Demand instances require a minimum commitment of one month

Answer

On-Demand instances are the cheapest pricing option for all workloads

Answer

On-Demand instances must be running continuously once launched

Question 13

A company wants to implement governance controls that prevent their developers from provisioning expensive instance types. Which approach is most effective?

Accepted Answer

Apply an SCP or IAM policy that denies launching specific expensive instance types. Service Control Policies (SCPs) or IAM policies can explicitly deny the launch of specific expensive instance types (e.g., `p3.2xlarge` or `x1e.32xlarge`) at the API level, preventing the action before any resources are created. This proactive governance approach enforces compliance in real time, unlike reactive or advisory methods. By attaching a deny effect for `ec2:RunInstances` with a condition on `ec2:InstanceType`, the policy blocks unauthorized instance provisioning regardless of the user's role or account.

Answer

Set an AWS Budget alert for when expensive instances are launched

Answer

Enable AWS Cost Explorer recommendations

Question 15

A company has 10 EC2 On-Demand instances running. They purchase a 1-year Compute Savings Plan for a commitment equivalent to 6 instances. What happens to the remaining 4 instances' cost?

Accepted Answer

The remaining 4 instances are charged at On-Demand rates. A Compute Savings Plan applies to any EC2 instance usage up to the committed hourly amount (in this case, equivalent to 6 instances). Usage beyond that commitment is charged at standard On-Demand rates. Therefore, the remaining 4 instances are billed at On-Demand prices because the Savings Plan does not cover usage exceeding the commitment.

Answer

The remaining 4 instances are free since the Savings Plan covers all usage

Answer

The remaining 4 instances are charged at Spot Instance rates

Answer

AWS suspends the 4 excess instances to enforce the Savings Plan limit
