CLF-C02 Billing, Pricing, and Support Practice Test 10 — 15 Questions

Question 1

A company archives historical transaction records in Amazon S3. The records are accessed frequently for the first 30 days after creation. After 30 days, access drops sharply to only a few times per year, but the company must be able to retrieve any record within 5 minutes if needed. The company wants to minimize storage costs while meeting the retrieval time requirement. Which combination of S3 storage classes should the company use?

Accepted Answer

Use S3 Standard for the first 30 days, then transition to S3 Glacier Flexible Retrieval.. Option B is correct because S3 Standard provides low-latency access for the first 30 days when records are frequently accessed, and then lifecycle rules transition the data to S3 Glacier Flexible Retrieval, which offers retrieval times of minutes (typically 1–5 minutes for expedited retrievals) at a much lower storage cost. This combination meets the 5-minute retrieval requirement while minimizing costs for data that is rarely accessed after 30 days.

Answer

Use S3 Standard for all data.

Answer

Use S3 Standard-IA for the first 30 days, then transition to S3 Glacier Deep Archive.

Answer

Use S3 One Zone-IA for the first 30 days, then transition to S3 Glacier Deep Archive.

Question 2

A company runs database servers that require consistent EC2 capacity 24/7 for the next 3 years. Which EC2 purchasing option provides the greatest discount compared to On-Demand pricing?

Accepted Answer

Reserved Instances (3-year, all upfront). Reserved Instances (RIs) with a 3-year term and all upfront payment provide the highest discount compared to On-Demand pricing because they commit to a consistent, predictable workload for an extended period. AWS offers significant pricing tiers for RIs, with the 3-year all upfront option yielding up to 72% discount over On-Demand, which is the greatest among all purchasing options for steady-state usage.

Answer

Spot Instances

Answer

On-Demand Instances

Answer

Dedicated Hosts

Question 3

A company runs non-critical batch analytics jobs that can be paused and restarted if interrupted. The jobs are flexible regarding when they run. Which EC2 purchasing option offers the lowest possible cost for this workload?

Accepted Answer

Spot Instances. Spot Instances offer the lowest possible cost because they use spare AWS EC2 capacity at a steep discount (up to 90% off On-Demand). Since the batch analytics jobs are non-critical, can be paused and restarted, and are flexible regarding when they run, they are an ideal fit for Spot Instances, which can be interrupted with a 2-minute warning when capacity is reclaimed.

Answer

Reserved Instances

Question 4

A solutions architect is designing a new architecture on AWS that includes EC2, RDS, S3, and data transfer. Before deploying anything, they want to estimate the monthly cost of running this architecture. Which AWS tool should they use?

Accepted Answer

AWS Pricing Calculator. AWS Pricing Calculator is the correct tool because it allows you to estimate the monthly cost of AWS services before deployment by specifying resource configurations (e.g., EC2 instance type, RDS storage, S3 data transfer). Unlike Cost Explorer, which analyzes historical costs, the Pricing Calculator provides upfront cost projections for new architectures.

Question 9

A company runs mixed workloads on AWS — some on EC2, some on Lambda, and some on Fargate — and wants to commit to a consistent hourly spend on compute to receive discounts similar to Reserved Instances, but with the flexibility to apply those discounts across different compute services and instance types. Which purchasing option provides this flexibility?

Accepted Answer

Savings Plans. Savings Plans (C) offer the flexibility to commit to a consistent hourly spend (e.g., $10/hour) and automatically apply the discount across EC2 instances, AWS Lambda, and AWS Fargate usage, regardless of instance family, size, OS, or region. This matches the requirement for a Reserved Instance-like discount with cross-service and cross-instance flexibility, which Reserved Instances cannot provide because they are tied to a specific instance family and region.

Answer

Reserved Instances

Answer

Spot Instances

Answer

Dedicated Hosts

Accepted Answer

AWS Free Tier. The AWS Free Tier is designed specifically for new AWS customers, offering limited free usage of select services—including t2.micro EC2 instances and 5 GB of Amazon S3 storage—for the first 12 months after account creation.

Enterprise On-Ramp Support

Question 15

A company runs workloads for multiple teams in a single AWS account and wants to track and report costs per team in their monthly AWS bill. Which feature allows them to categorise and report AWS costs by team?

Accepted Answer

AWS Cost Allocation Tags. AWS Cost Allocation Tags allow you to tag AWS resources with team-specific metadata (e.g., 'Team: Engineering') and then activate those tags in the Billing and Cost Management console. Once activated, AWS generates cost reports that group and summarize charges by those tags, enabling per-team cost tracking in the monthly bill. This is the correct feature because it directly categorizes costs at the resource level and reports them in billing data.
