A team wants to avoid buying and maintaining infrastructure before it knows how much capacity it will need. Which description best matches AWS's general pricing approach?

  1. A

    Pay a fixed charge to own equivalent infrastructure regardless of use.

  2. B

    Pay for the resources and activity used.

  3. C

    Pay only for data stored, regardless of compute or requests.

  4. D

    Pay one flat rate for all AWS services and Regions.

A development team uses an EC2 instance only during work hours. It wants to reduce costs overnight while retaining data on attached storage. Which statement best describes the likely cost effect of stopping the instance?

  1. A

    Stopping the instance automatically ends every charge for its attached resources.

  2. B

    Leaving the instance running is cheaper because storage is billed only while compute runs.

  3. C

    Stopping the instance can reduce compute charges, but attached storage may still incur costs.

  4. D

    Terminating the instance guarantees that all related charges are refunded.

A company is considering moving rarely accessed archive data to a lower-rate S3 storage class. What should it examine before deciding whether the change will reduce total costs?

  1. A

    Compare storage rates with retrieval charges and any minimum-storage-duration rules.

  2. B

    Choose the class with the lowest storage rate, because retrieval does not affect the bill.

  3. C

    Avoid considering access patterns because all storage classes have identical charges.

  4. D

    Use the least expensive class for every dataset, regardless of how often it is accessed.

A team is matching EC2 purchase options to workload needs. Which statements about the options are correct? Select all that apply.

  1. A

    On-Demand can suit flexible usage without a long-term commitment.

  2. B

    Savings Plans can lower eligible costs in exchange for a usage commitment.

  3. C

    Spot Instances use spare capacity and may be interrupted.

  4. D

    Spot Instances guarantee uninterrupted capacity for a long-term term.

  5. E

    Reserved Instances can lower eligible costs in exchange for a configuration commitment.

A service sends increasingly large files from AWS to internet users, while its compute and storage usage stay constant. Which pricing dimension could cause its bill to rise?

  1. A

    No data-transfer costs are possible as long as the compute usage is unchanged.

  2. B

    Only the number of API requests can affect transfer charges.

  3. C

    Data-transfer-out costs may rise because charges can depend on the volume sent to the internet.

  4. D

    The cost is determined only by the amount of data stored, not by movement.

A service uses tiered pricing. What should a cost estimator account for as projected usage changes?

  1. A

    The unit rate must remain constant at every usage level.

  2. B

    The unit rate can change at different usage levels.

  3. C

    Tiers apply only to data transfer and never to other services.

  4. D

    A tier means all services are charged one flat monthly fee.

An architect assumes that every transfer into AWS from the internet is free, regardless of service and route. Which response best reflects the pricing guidance?

    Every transfer into AWS is always free, regardless of service or route.

  2. B

    All inbound internet data is charged at the same rate as outbound data.

  3. C

    Inbound transfer costs are determined only by the instance type.

  4. D

    Inbound internet transfer is generally not charged, but this is not universal for every service or path.

A batch-processing workload can pause and resume if its compute capacity is interrupted. Which EC2 purchase option aligns with this workload characteristic?

  1. A

    On-Demand instances, because they are designed for workloads that must not be interrupted

  2. B

    Reserved Instances, because they use spare capacity that AWS can reclaim

  3. C

    Spot Instances, because the workload can tolerate interruptions

  4. D

    Savings Plans, because they have no usage or configuration commitment
