AWS Cloud Practitioner — All Questions

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.
