- b.A fixed monthly subscription per function
- c.A one-time upfront payment that covers all future invocations of the function
- d.A charge based on the number of requests and the duration your code runs✓
AWS Lambda charges by the number of requests and the compute duration (rounded to the millisecond) that your function runs, with no charge when idle. This usage-based model aligns cost with actual execution.
For Amazon S3, which factors primarily determine your monthly cost?
- a.The number of IAM users in the account
- b.The amount of storage, the storage class, requests, and data transfer out✓
- c.Only the number of buckets you create
- d.A single flat monthly fee no matter how much or how little data you actually store
S3 costs depend on how much data you store, the storage class chosen, the number and type of requests, and data transfer out of AWS. Choosing the right storage class and lifecycle rules helps optimize these costs.
Which AWS pricing principle is demonstrated by receiving a lower per-GB price as your Amazon S3 storage volume crosses higher usage tiers?
- a.Pay only after a multi-year commitment
- b.Pay more by reserving capacity
- c.Pay a single flat rate regardless of the total volume you use
- d.Pay less per unit when you use more (volume-based discounts)✓
AWS offers tiered, volume-based pricing on some services so that the per-unit price decreases as usage grows. This is distinct from commitment-based discounts like Reserved Instances or Savings Plans.
Which tool would you use to compare the cost of running a workload on-premises versus on AWS to build a business case for migration?
- a.AWS WAF
- b.Amazon GuardDuty continuous threat-detection and account-monitoring service dashboards view
- c.Amazon Route 53

On-Demand pricing charges for capacity by the hour or second with no upfront cost or commitment, making it flexible for unpredictable or short-term workloads. Committed options like Reserved Instances and Savings Plans trade flexibility for lower rates.
A workload runs steadily 24/7 for the next three years with predictable usage. Which purchasing approach typically minimizes cost?
- a.Dedicated Hosts billed hourly with no commitment
- b.Spot Instances only
- c.On-Demand Instances only
- d.A three-year Savings Plan or Reserved Instances✓
For steady, predictable, long-running workloads, committing to a one- or three-year Savings Plan or Reserved Instances yields the largest discounts over On-Demand. Spot suits interruptible work, and On-Demand is best for variable usage.
What does the AWS Billing Dashboard primarily let you do?
- a.View current and past charges, spending trends, and access billing tools in one place✓
- b.Trace each individual request as it travels across all of your distributed microservices
- c.Provision new EC2 instances
- d.Encrypt data stored in Amazon S3
The AWS Billing Dashboard gives a central view of current month-to-date spend, historical trends, and links to billing tools such as Cost Explorer and Budgets. It is the starting point for understanding and managing account charges.
Which is a benefit of using AWS Organizations for a company with many AWS accounts, from a cost perspective?
- a.It automatically finds and deletes any unused resources across all of the accounts to save money
- b.It guarantees a fixed monthly bill
- c.Combined usage across accounts can qualify for volume discounts under one consolidated bill✓
- d.It removes the need to monitor usage
AWS Organizations enables consolidated billing, which aggregates usage across accounts so the group can reach volume-pricing tiers and share commitment discounts under one bill. It simplifies payment while preserving per-account visibility.
Which support plan tier includes access to online resources, whitepapers, documentation, and the AWS support community at no additional charge?
- a.Business
- b.Basic✓
- c.Enterprise
- d.Developer
Basic Support is included free with every AWS account and provides access to documentation, whitepapers, support forums, and account and billing assistance. Technical support with response-time commitments requires a paid plan.
Which of the following usage would typically incur a charge even when other Free Tier limits are respected?
- a.Reading AWS documentation
- b.Using an always-free service within its stated limits
- c.Staying exactly within the twelve-month Free Tier limits for each service
- d.Exceeding the monthly Free Tier hours for an EC2 instance type✓
Exceeding a Free Tier allowance, such as running more EC2 hours than the offer includes, triggers standard pay-as-you-go charges for the overage. Staying within limits and using always-free offers within their bounds avoids charges.
What is the main advantage of the Compute Savings Plans over EC2 Instance Savings Plans?
- a.Compute Savings Plans apply broadly across instance families, Regions, and services like Fargate and Lambda✓
- b.Compute Savings Plans require no commitment
- c.Compute Savings Plans always give the single largest possible discount of any purchase option that is available
- d.Compute Savings Plans only apply to a single instance type
Compute Savings Plans offer the most flexibility, automatically applying the discount across any instance family, size, Region, tenancy, and even to Fargate and Lambda usage. EC2 Instance Savings Plans give a deeper discount but are limited to a chosen instance family in a Region.
Which action helps ensure you are notified before a project's monthly spending exceeds an approved amount?
- a.Attach an Elastic IP to every instance
- b.Turn off AWS CloudTrail
- c.Enable Amazon Macie scanning on all of your buckets
- d.Create an AWS Budget with an alert threshold✓
Creating an AWS Budget with alert thresholds sends notifications as actual or forecasted spend approaches or exceeds the limit, helping teams stay within approved amounts. It is a core proactive cost-control practice.
Which of the following would AWS Trusted Advisor NOT typically help with directly?
- a.Checking whether you are approaching service limits
- b.Identifying idle load balancers to reduce cost
- c.Flagging security groups with unrestricted access
- d.Writing the business logic of your application✓
Trusted Advisor provides best-practice checks for cost, security, fault tolerance, performance, and service limits, but it does not write application code. It advises on your environment's configuration and usage, not your software logic.
A startup expects highly variable, unpredictable traffic in its first months. Which pricing model best matches this uncertainty while minimizing commitment risk?
- a.On-Demand pricing✓
- b.A three-year Savings Plan
- c.Dedicated Hosts with a one-year commitment
- d.Three-year Reserved Instances
On-Demand pricing matches unpredictable, variable workloads because it requires no commitment and charges only for what is used. Long-term commitments make sense later, once usage patterns become predictable.
Which best describes how AWS charges for most services?
- a.A one-time lifetime license per service
- b.Based on actual usage of each service, such as compute time, storage, and data transfer✓
- c.A single flat monthly fee that covers completely unlimited use of every AWS service offered
- d.Only an annual subscription negotiated in advance
AWS generally bills based on metered usage of each service, such as compute hours, storage consumed, requests, and data transfer, following the pay-as-you-go model. This lets costs scale with actual consumption.
Which tool helps you allocate and track shared costs and view amortized costs of Reserved Instances and Savings Plans over time?
- a.AWS Shield
- b.AWS Cost Explorer✓
- c.Amazon Inspector service
- d.Amazon Cognito
AWS Cost Explorer can display costs including amortized views of Reserved Instances and Savings Plans and, with cost categories and allocation tags, helps allocate shared spend. It supports understanding true cost distribution over time.
Which statement about AWS support plan pricing is accurate?
- a.All support plans are free
- b.Support plans are billed only one single time, at the moment the account is first created
- c.Paid support plan cost often scales with your monthly AWS usage, subject to minimums✓
- d.Enterprise Support is cheaper than Developer Support
Paid AWS Support plans are commonly priced as the greater of a monthly minimum or a percentage of monthly AWS usage, so cost generally scales with spend. Basic Support is free, while Enterprise is the most comprehensive and costly tier.
Which service or feature would help a finance team automatically stop or receive alerts when a sandbox account's spend is abnormally high?
- a.Amazon EBS point-in-time volume snapshots scheduled hourly
- b.AWS Budgets combined with Cost Anomaly Detection✓
- c.AWS Direct Connect
- d.Amazon Route 53
AWS Budgets can alert (and trigger actions) when spend crosses thresholds, and Cost Anomaly Detection uses machine learning to flag unusual spending. Together they help finance teams catch and respond to abnormal costs.
Why might an organization choose EC2 Instance Savings Plans over Compute Savings Plans?
- a.Because they require no commitment at all
- b.Because they automatically apply to both Lambda and Fargate compute usage across your whole account
- c.Because they are the only option that includes support
- d.To get a deeper discount in exchange for committing to a specific instance family in a Region✓
EC2 Instance Savings Plans provide a larger discount than Compute Savings Plans but restrict the commitment to a particular instance family within a Region. The trade-off is less flexibility for a deeper price reduction.
What does 'amortized cost' represent in AWS cost reporting?
- a.The total data stored in Amazon S3
- b.Upfront commitment charges spread evenly across the term they cover✓
- c.The cost of outbound data transfer only
- d.The current total number of running EC2 instances across the whole account
Amortized cost distributes upfront payments for commitments like Reserved Instances or Savings Plans evenly over the commitment term, rather than showing the full charge at purchase. This gives a smoother, more representative view of ongoing costs.
A company wants a single monthly invoice for 15 AWS accounts while keeping each team's costs visible. Which capability enables this?
- a.Consolidated billing through AWS Organizations✓
- b.AWS Direct Connect
- c.Elastic Load Balancing
- d.Automatic cross-Region replication of resources
Consolidated billing in AWS Organizations produces one invoice for the payer account across all member accounts while still allowing per-account cost tracking. It also aggregates usage for potential volume discounts.
Which is the best first step to control costs when you notice an unexpectedly high bill driven by many small services?
- a.Immediately upgrade to the Enterprise Support plan to reduce your per-service prices
- b.Immediately delete the entire AWS account
- c.Turn off all monitoring to stop the charges
- d.Use Cost Explorer to identify which services and resources are driving the spend✓
Cost Explorer lets you break down spend by service, account, and tag to pinpoint what is driving costs before taking action. Understanding the source is the essential first step to targeted cost reduction.
Which pricing benefit is unique to committing to Reserved Instances or Savings Plans rather than using On-Demand?
- a.Charges only for storage and never for compute
- b.No ability to run instances continuously
- c.Lower rates in exchange for a one- or three-year usage commitment✓
- d.Automatic elimination of every outbound data-transfer fee across all Regions
Reserved Instances and Savings Plans reduce compute costs significantly in return for committing to a one- or three-year term, unlike On-Demand which has no commitment or discount. The right choice depends on how predictable the workload is.
Which service provides on-demand access to compliance reports, and is free of charge but is not itself a cost-management tool?
- a.AWS Budgets
- b.AWS Cost Explorer
- c.AWS Artifact✓
- d.AWS Pricing Calculator
AWS Artifact offers free, on-demand access to AWS compliance reports and agreements, but it is a governance/compliance tool rather than a cost-management one. Cost management is handled by tools like Cost Explorer, Budgets, and the Pricing Calculator.
Which statement about the relationship between AWS Support plans and Trusted Advisor is correct?
- a.AWS Trusted Advisor requires a completely separate paid subscription that must be purchased outside of the standard AWS Support plans
- b.Only the Basic plan gets the full set of checks
- c.Trusted Advisor is unavailable on every plan
- d.Basic and Developer plans get a limited set of Trusted Advisor checks, while Business and Enterprise get the full set✓
All accounts get a core subset of Trusted Advisor checks, while the full set across all five categories is unlocked with Business and Enterprise (and Enterprise On-Ramp) Support. Higher tiers therefore provide deeper cost and security guidance.
Which Reserved Instance payment option provides the largest discount?
- a.Partial Upfront combined with lower monthly charges
- b.All Upfront✓
- c.Paying only after the reserved term has fully ended
- d.No Upfront, spread as equal monthly charges over the whole term with no initial payment
Reserved Instances offer three payment options, and All Upfront (paying the entire amount at purchase) gives the biggest discount. No Upfront gives the smallest discount, and Partial Upfront falls in between.
