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

Question 1

Which statement about AWS data transfer pricing is correct?

Accepted Answer

Data transfer into AWS from the internet is free; outbound data transfer to the internet is charged. AWS does not charge for data transfer into AWS from the internet, but it does charge for outbound data transfer from AWS to the internet. This pricing model is fundamental to AWS's cost structure, encouraging data ingestion while charging for egress. For example, data uploaded to Amazon S3 is free, but downloading that data to the internet incurs per-GB charges.

Answer

All data transfer into and out of AWS is free

Answer

Data transfer between EC2 instances in different Availability Zones is free

Answer

Data transfer between AWS Regions is free because it stays within AWS infrastructure

Question 2

A company wants to use AWS for a short-term proof-of-concept project lasting one month. They need EC2 instances and RDS databases but don't want any long-term commitment. Which pricing model is most appropriate?

Accepted Answer

On-Demand pricing. On-Demand pricing is the most appropriate for a short-term proof-of-concept lasting only one month because it requires no upfront payment or long-term commitment. You pay for compute and database capacity by the hour or second, and you can stop or terminate resources at any time without penalty. This aligns perfectly with the temporary, flexible nature of a one-month project.

Answer

Reserved Instances (1-year, All Upfront)

Answer

Savings Plans (3-year commitment)

Answer

Spot Instances for all workloads

Question 3

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

AWS Cost Explorer

Answer

AWS Personal Health Dashboard

Answer

Amazon CloudWatch

Question 4

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 5

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 6

A company's cloud finance team wants to implement cloud financial management (FinOps) on AWS. Which combination of AWS services provides the most comprehensive cost visibility, budgeting, and optimization capabilities?

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 7

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 8

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

Delete all non-production resources immediately

Answer

Switch all resources to Spot Instances

Answer

Enable all AWS services to trigger CloudWatch alarms

Question 9

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

Spot Instance savings

Answer

Savings Plans commitment discounts

Question 10

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.

Answer

Question 12

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 13

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 14

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

Answer

Enable Trusted Advisor and review weekly

Question 15

Which AWS service provides a concierge-like experience for navigating AWS services and finding the right resources, primarily available to Enterprise Support customers?

Accepted Answer

AWS Support Concierge (Account Team). AWS Support Concierge (Account Team) is a dedicated service provided to Enterprise Support customers that offers a concierge-like experience for navigating AWS services and finding the right resources. It acts as a single point of contact for account-level inquiries, such as billing, account management, and service limit increases, rather than providing technical troubleshooting.
