CLF-C02 practice questions: Billing, Pricing, and Support

Answer: D. Task Statement 4.2 asks candidates to distinguish AWS Budgets from AWS Cost Explorer and the neighbouring cost tools. The AWS Cost Management user guide describes 'Setting a monthly cost budget with a fixed target amount to track all costs associated with your account' and states that 'You can choose to be alerted for both actual (after accruing) and forecasted (before accruing) spends' and that 'You can have notifications sent to an Amazon SNS topic, to an email address, or to both.' The Amazon CloudWatch user guide states of a billing alarm that 'It triggers only when the current billing exceeds the threshold. It doesn't use projections based on your usage so far in the month.' AWS Cost Anomaly Detection is described as a feature that 'uses machine learning models to detect and alert on anomalous spend patterns in your deployed AWS services'.

Answer: D. Task Statement 4.1 lists Dedicated Hosts among the compute purchasing options. The Amazon EC2 billing and purchasing options page states that with Dedicated Hosts you 'Pay for a physical host that is fully dedicated to running your instances, and bring your existing per-socket, per-core, or per-VM software licenses to reduce costs,' and describes Dedicated Instances as 'Pay, by the hour, for instances that run on single-tenant hardware.' The same page adds that 'Dedicated Hosts or Dedicated Instances can help you address compliance requirements and reduce costs by using your existing server-bound software licenses,' which is why the per-socket and per-core wording is what separates them here.

Answer: C. Task Statement 4.1 asks candidates to describe Reserved Instance behavior in AWS Organizations. The Amazon EC2 user guide page 'How billing works with Reserved Instances', section 'Reserved Instances and consolidated billing', states: 'The pricing benefits of Reserved Instances are shared when the purchasing account is part of a set of accounts billed under one consolidated billing payer account.' The AWS Billing user guide page 'Reserved Instances and Savings Plans discount sharing' gives the order under organization-wide sharing: 'Commitments benefit the account owner first' and 'After satisfying the account owner, remaining benefits can be shared with other organization accounts.' The same page states that 'The management account of an organization can control Reserved Instance discount and Savings Plans discount sharing for any accounts in that organization.'

Answer: C. Task Statement 4.2 lists pricing information for AWS services. The Amazon VPC pricing page states: 'Any public IPv4 address associated with a resource launched in an Amazon VPC, and public IPv4 addresses assigned to AWS Global Accelerator and AWS Site-to-Site VPN tunnel endpoints are charged as in-use public IPv4 address.' It lists 'Hourly charge for In-use Public IPv4 Address $0.005' and 'Hourly charge for Idle Public IPv4 Address $0.005', and adds: 'The price is the same whether the public IPv4 address is in-use public IPv4 addresses that is associated with an AWS resource you own, or an idle public IPv4 addresses in your AWS account not associated with any AWS resources.' The Amazon EC2 On-Demand pricing page says the same of Elastic IP addresses: 'All In-use and Idle Elastic IP addresses are charged.' Source: https://aws.amazon.com/vpc/pricing/

Answer: C. Task Statement 4.1 covers pricing options for the storage options and tiers. The Amazon S3 user guide page 'Understanding and managing Amazon S3 storage classes' states: 'The S3 Standard-IA and S3 One Zone-IA storage classes are suitable for objects larger than 128 KB that you plan to store for at least 30 days. If an object is less than 128 KB, Amazon S3 charges you for 128 KB. If you delete an object before the end of the 30-day minimum storage duration period, you are charged for 30 days.' Its comparison table lists S3 Standard-IA with 'Min billable object size: 128 KB' and 'Availability Zones: >= 3', and footnotes that S3 Glacier Flexible Retrieval and S3 Glacier Deep Archive require '40 KB of additional metadata for each archived object'. Millions of 16 KB objects in Standard-IA are therefore billed as 128 KB each.
