CLF-C02 Billing, Pricing, and Support Practice Test 14 — 15 Questions

Question 1

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

Question 2

A company is reviewing their AWS bill and notices charges for Amazon CloudWatch. Which specific CloudWatch usage would NOT incur additional charges beyond the CloudWatch free tier?

Accepted Answer

Basic monitoring (5-minute metrics) for EC2 instances. Basic monitoring for EC2 instances provides metrics at 5-minute intervals at no additional cost, as it is included in the CloudWatch free tier. Detailed monitoring (1-minute metrics) incurs charges because it requires more frequent data collection and storage. Therefore, basic monitoring is the only option that does not generate extra charges beyond the free tier.

Answer

Detailed monitoring (1-minute metrics) for EC2 instances

Answer

Publishing 100 custom metrics

Answer

Storing CloudWatch Logs beyond the free tier

Question 3

Which AWS service or feature provides a notification when AWS is performing planned maintenance that may affect your resources?

Accepted Answer

AWS Health Dashboard. AWS Health Dashboard (specifically the AWS Personal Health Dashboard) provides proactive notifications and alerts when AWS is performing planned maintenance that may affect your resources. It gives you a personalized view of service health events, including scheduled maintenance, that are relevant to your AWS account and resources.

Question 4

A company has unused Reserved Instances that don't match their current infrastructure. What option allows them to recoup some cost from unused RIs?

Accepted Answer

Sell them on the Reserved Instance Marketplace. The AWS Reserved Instance Marketplace allows customers to sell unused Reserved Instances (RIs) to other AWS users, enabling them to recoup some of the upfront costs. This is the only option that directly addresses the need to recover costs from RIs that no longer match the current infrastructure, as AWS does not offer refunds or free transfers for unused RIs.

Answer

Convert them to Spot Instances

Answer

Request a refund from AWS for unused RI capacity

Answer

Transfer them to another AWS account for free

Question 5

Question 7

A company wants to receive a notification whenever a new AWS root account sign-in occurs. Which combination of services achieves this?

Accepted Answer

CloudTrail + EventBridge + SNS notification. AWS CloudTrail logs all root account sign-in events as `ConsoleLogin` events in the management events trail. Amazon EventBridge can be configured with a rule that matches this specific event pattern (e.g., `detail.userIdentity.type` = `Root` and `detail.eventName` = `ConsoleLogin`). The rule then triggers an Amazon SNS topic to send a notification (email, SMS, etc.) to the designated recipients. This combination provides a real-time, event-driven notification for root account activity.

Answer

AWS Config + AWS Lambda

Answer

AWS Budgets + SES email

Answer

Amazon GuardDuty finding + S3 export

Question 8

Which statement correctly describes how Amazon S3 pricing works?

Accepted Answer

S3 charges per GB stored, per request, and for outbound data transfer. Amazon S3 pricing is based on a pay-as-you-go model where you are charged for the amount of storage you use (per GB per month), the number and type of requests (e.g., PUT, GET, LIST), and data transfer out to the internet. This granular billing reflects actual usage, making option B correct.

Answer

S3 charges a flat monthly fee regardless of storage used

Answer

S3 storage is free; only data transfer is charged

Answer

S3 charges by the number of files stored, not the size

Question 9

A company currently pays $50,000/month for on-premises infrastructure. They project that running the equivalent workload on AWS will cost $35,000/month including all data transfer. What is the annual AWS cost savings?

Accepted Answer

$180,000. The monthly cost savings are $50,000 - $35,000 = $15,000. Annualizing this gives $15,000 × 12 = $180,000. Option B is correct because it correctly multiplies the monthly savings by 12 to compute the annual savings.

Answer

$15,000

Answer

$420,000

Answer

$600,000

Question 10

A company uses AWS Support and wants to know which plan provides the fastest response time for a business-critical system outage causing complete service disruption.

Accepted Answer

Enterprise Support (15-minute response). AWS Support plans define response times based on severity. For a business-critical system outage (severity-critical, complete service disruption), Enterprise Support provides a 15-minute response time, which is the fastest available. This is explicitly documented in AWS Support plan details, making option C correct.

Answer

Business Support (1-hour response)

Answer

Enterprise On-Ramp (30-minute response)

Answer

Developer Support (12-hour response)

Question 11

What does the AWS Free Tier offer to new AWS customers?

Accepted Answer

Free usage of certain services up to specified limits for 12 months. The AWS Free Tier is designed to allow new customers to explore and experiment with AWS services at no cost for the first 12 months after sign-up. It includes specific usage limits per service (e.g., 750 hours of Amazon EC2 t2.micro instances per month, 5 GB of Amazon S3 standard storage, etc.), after which standard pay-as-you-go rates apply. This helps customers gain hands-on experience without upfront financial commitment.

Answer

Unlimited free usage of all AWS services forever

Answer

Free usage only for the first month after signup

Answer

Free usage for all services with a credit card on file

Question 12

A company has predictable workloads running 24/7. Which EC2 pricing option would provide the most significant cost savings compared to On-Demand pricing?

Accepted Answer

Reserved Instances. Reserved Instances (RIs) provide a significant discount (up to 72%) over On-Demand pricing in exchange for a one- or three-year commitment. Since the company has predictable, 24/7 workloads, RIs are the ideal choice because they match the steady-state usage pattern and offer the highest cost savings for always-on instances.

Answer

Spot Instances

Answer

On-Demand Instances

Answer

Dedicated Hosts

Question 13

Which AWS tool provides recommendations to help reduce costs, improve performance, enhance security, and increase fault tolerance?

Accepted Answer

AWS Trusted Advisor. AWS Trusted Advisor is the correct answer because it provides real-time guidance and recommendations across five categories: cost optimization, performance, security, fault tolerance, and service limits. It evaluates your AWS environment against AWS best practices and generates actionable recommendations to reduce costs, improve performance, enhance security, and increase fault tolerance. This makes it the only tool among the options that covers all four areas mentioned in the question.

Question 15

Which AWS pricing model allows customers to commit to a consistent amount of compute usage (measured in $/hour) for a 1 or 3-year term in exchange for significant discounts, without being locked to specific instance types?

Accepted Answer

Compute Savings Plans. Compute Savings Plans offer the flexibility to commit to a consistent amount of compute usage (measured in $/hour) for a 1- or 3-year term, providing significant discounts (up to 66%) without requiring you to lock into specific instance types, families, or regions. This model automatically applies the discount to any EC2 instance, Fargate, or Lambda usage within the committed compute commitment, making it the correct answer.
