CLF-C02 Billing, Pricing, and Support Practice Test 11 — 15 Questions

Question 1

A company has bring-your-own-license (BYOL) server software that is licensed per physical CPU socket. They need to run this software on AWS and require visibility into and control over the physical host their instances run on. Which EC2 option meets this requirement?

Accepted Answer

Dedicated Hosts. Dedicated Hosts provide you with a physical server fully dedicated to your use, allowing you to see and control the physical host's CPU sockets and cores. This is essential for bring-your-own-license (BYOL) software that is licensed per physical CPU socket, as you must ensure compliance with the license terms by managing the exact hardware configuration.

A startup has a development AWS account and wants the minimum paid AWS Support plan that provides email-based technical support from AWS staff. They do not need 24/7 phone access. Which is the minimum support plan that provides access to AWS technical support engineers?

Accepted Answer

Developer Support. The Developer Support plan is the minimum AWS Support plan that provides access to AWS technical support engineers via email during business hours. Basic Support offers no technical support from AWS staff, only account and billing assistance. Business and Enterprise Support include 24/7 phone and chat support, which exceeds the stated requirement for email-only access.

Question 3

Which AWS pricing model provides the largest discount compared to On-Demand pricing in exchange for a 1 or 3-year commitment with full upfront payment?

Accepted Answer

Reserved Instances (All Upfront, 3-year). Reserved Instances (All Upfront, 3-year) provide the largest discount compared to On-Demand pricing because the customer commits to a 1- or 3-year term and pays the entire amount upfront, which gives AWS predictable capacity planning and reduces billing overhead. This model can offer discounts of up to 72% off On-Demand rates, significantly more than partial upfront or no upfront options, and is the most cost-effective for steady-state workloads.

On-Demand Instances

Answer

Compute Savings Plans (1-year, No Upfront)

Question 4

A company uses multiple AWS accounts managed under AWS Organizations. Which service allows them to share Reserved Instance discounts and Savings Plans across all accounts in the organization?

Accepted Answer

AWS Organizations with consolidated billing. AWS Organizations with consolidated billing enables you to aggregate usage across all member accounts, allowing Reserved Instance (RI) discounts and Savings Plans to be shared. This means that unused capacity from one account can be applied to reduce costs in another account within the same organization, maximizing overall savings.

Which AWS support plan provides access to AWS Infrastructure Event Management (IEM) for product launches and migrations at no additional charge?

Accepted Answer

Enterprise Support. The Enterprise Support plan includes AWS Infrastructure Event Management (IEM) at no additional charge, providing architectural and scaling guidance for product launches and migrations. This is a key differentiator from lower-tier plans, which either do not include IEM or require an extra fee.

Question 8

A company is evaluating whether to use AWS Compute Savings Plans or EC2 Instance Savings Plans. Which statement correctly describes when EC2 Instance Savings Plans provide the highest discount?

Accepted Answer

When the workload uses a consistent instance family within a single Region. EC2 Instance Savings Plans offer the highest discount (up to 72% compared to On-Demand) because they require a commitment to a specific instance family within a single AWS Region. This allows AWS to optimize capacity planning and pass greater savings to the customer, whereas Compute Savings Plans are more flexible but provide lower discounts (up to 66%).

Answer

When the workload spans multiple AWS Regions

Answer

When the workload uses multiple instance families

Answer

When the workload runs on AWS Fargate

Question 9

Question 10

A company wants to use AWS free tier for testing new services. Which statement about the AWS Free Tier is accurate?

Accepted Answer

The Free Tier includes a mix of 12-month free, always free, and short-term trial offers. Option B is correct because the AWS Free Tier is structured into three categories: 12-month free offers (e.g., 750 hours of EC2 t2.micro per month), always free offers (e.g., 1 million Lambda requests per month), and short-term trials (e.g., 30-day free trial of Amazon Inspector). This mix allows customers to test services without incurring costs for the specified limits and durations.

Answer

The Free Tier is available indefinitely for all AWS services

Answer

The Free Tier applies equally to all AWS accounts including Enterprise support customers

Answer

AWS does not charge if you stay within Free Tier limits for any service

Question 11

Which AWS support plan is the minimum level required to access the full set of AWS Trusted Advisor checks?

Accepted Answer

Business. The Business support plan is the minimum level required to access the full set of AWS Trusted Advisor checks. While the Basic and Developer plans provide access to only a subset of seven core checks (such as service limits and security groups), the Business plan unlocks all Trusted Advisor checks, including cost optimization, performance, and fault tolerance checks. The Enterprise plan also provides full access but is not the minimum level required.

Answer

Enterprise

Question 12

A company has unpredictable, short-lived batch processing workloads that can be interrupted. Which EC2 purchasing option would provide the lowest cost for these workloads?

Accepted Answer

Spot Instances. Spot Instances (Option C) are the correct choice because they offer unused EC2 capacity at steep discounts (up to 90% off On-Demand) and are ideal for fault-tolerant, flexible, short-lived, or interruptible workloads. Since the company's batch processing jobs are unpredictable and can be interrupted, Spot Instances provide the lowest cost while tolerating the risk of termination when AWS needs the capacity back.

Answer

On-Demand Instances

Answer

Reserved Instances (1-year, No Upfront)

Answer

Dedicated Hosts

Question 13

A company uses AWS Organizations. They want to ensure that member accounts cannot turn off CloudTrail or AWS Config in their accounts. What is the most effective way to enforce this?

Accepted Answer

Apply Service Control Policies (SCPs) at the organization level. Service Control Policies (SCPs) are the most effective way to enforce guardrails across all member accounts in AWS Organizations. SCPs can deny the ability to disable CloudTrail or AWS Config at the organization, organizational unit (OU), or account level, and they cannot be overridden by IAM policies in member accounts. This ensures that even account administrators cannot turn off these services, providing a centralized security control.

Answer

Configure IAM policies in each account to deny these actions

Answer

Use AWS Config rules to detect and alert on violations

Answer

Enable MFA delete on all accounts

Question 14

Which AWS service provides detailed billing reports that can be delivered hourly to Amazon S3 for custom analysis with tools like Amazon Athena or Redshift?

Accepted Answer

AWS Cost and Usage Report (CUR). AWS Cost and Usage Report (CUR) is the correct service because it provides the most granular billing data, including hourly usage and cost details, which can be delivered to an Amazon S3 bucket. This allows you to use analytics tools like Amazon Athena or Amazon Redshift to run custom queries and perform in-depth analysis on the raw billing data.

Answer

Question 15

A company wants to purchase EC2 capacity that provides a discount over On-Demand pricing and is available only when AWS has excess capacity, with the option of interruption with a 2-minute warning. Which option is this?

Accepted Answer

Spot Instances. Spot Instances (Option C) are correct because they offer a significant discount over On-Demand pricing but can be interrupted by AWS with a 2-minute warning when AWS needs the capacity back. This matches the scenario of purchasing EC2 capacity that is available only when AWS has excess capacity and includes the risk of interruption.
