Billing and Pricing Flashcards
A startup wants to provision an EC2 instance for the lowest possible cost for a long-term duration but needs to make sure that the instance would never be interrupted. As a Cloud Practitioner, which of the following options would you recommend?
A. EC2 Reserved Instance (RI)
B. EC2 Dedicated Host
C. EC2 Sot Instance
D. EC2 On-Demand Instance
A. EC2 Reserved Instance (RI)
Explanation
Correct option:
EC2 Reserved Instance (RI)
An EC2 Reserved Instance (RI) provides you with significant savings (up to 75%) on your Amazon EC2 costs compared to On-Demand Instance pricing. A Reserved Instance (RI) is not a physical instance, but rather a billing discount applied to the use of On-Demand Instances in your account. You can purchase a Reserved Instance (RI) for a one-year or three-year commitment, with the three-year commitment offering a bigger discount. A reserved instance (RI) cannot be interrupted. So this is the correct option.
EC2 Pricing Options Overview: via - https://aws.amazon.com/ec2/pricing/
Incorrect options:
EC2 On-Demand Instance - An EC2 On-Demand Instance is an instance that you use on-demand. You have full control over its lifecycle — you decide when to launch, stop, hibernate, start, reboot, or terminate it. There is no long-term commitment required when you purchase On-Demand Instances. There is no upfront payment and you pay only for the seconds that your On-Demand Instances are running. The price per second for running an On-Demand Instance is fixed. On-demand instances cannot be interrupted. However, On-demand instances are not as cost-effective as Reserved instances, so this option is not correct.
EC2 Spot Instance - An EC2 Spot Instance is an unused EC2 instance that is available for less than the On-Demand price. Because Spot Instances enable you to request unused EC2 instances at steep discounts (up to 90%), you can lower your Amazon EC2 costs significantly. Spot Instances are well-suited for data analysis, batch jobs, background processing, and optional tasks. These can be terminated at short notice, so these are not suitable for critical workloads that need to run at a specific point in time. So this option is not correct for the given use-case.
EC2 Dedicated Host - An Amazon EC2 Dedicated Host allows you to use your eligible software licenses from vendors such as Microsoft and Oracle on Amazon EC2 so that you get the flexibility and cost-effectiveness of using your licenses, but with the resiliency, simplicity, and elasticity of AWS. An Amazon EC2 Dedicated Host is a physical server fully dedicated for your use, so you can help address corporate compliance requirement. It is not cost-efficient compared to an On-Demand instance. So this option is not correct.

The DevOps team at an IT company is moving 500 GB of data from an EC2 instance to an S3 bucket in the same region. Which of the following scenario captures the correct charges for this data transfer?
A. The company would only be charged for the outbound data transfer from EC2 instance
B. THe company would be charged for both the outbound data transfer from EC2 instace as well as the inbound data transfer into the S3
C. The company would not be charged for this data transfer
D. The company would only be charged for the inbound data transfer into the S3 bucket
C. The company would not be charged for this data transfer
Explanation
Correct option:
The company would not be charged for this data transfer
There are three fundamental drivers of cost with AWS: compute, storage, and outbound data transfer. In most cases, there is no charge for inbound data transfer or data transfer between other AWS services within the same region. Outbound data transfer is aggregated across services and then charged at the outbound data transfer rate.
Per AWS pricing, data transfer between S3 and EC2 instances within the same region is not charged, so there would be no data transfer charge for moving 500 GB of data from an EC2 instance to an S3 bucket in the same region.
Incorrect options:
The company would only be charged for the outbound data transfer from EC2 instance
The company would only be charged for the inbound data transfer into the S3 bucket
The company would be charged for both the outbound data transfer from EC2 instance as well as the inbound data transfer into the S3 bucket
These three options contradict the details provided earlier in the explanation, so these options are incorrect.

Amazon Relational Database Service (Amazon RDS)
The following AWS services support reservations to optimize costs:
Amazon EC2 Reserved Instances (RI): You can use Amazon EC2 Reserved Instances (RI) to reserve capacity and receive a discount on your instance usage compared to running On-Demand instances.
Amazon DynamoDB Reserved Capacity: If you can predict your need for Amazon DynamoDB read-and-write throughput, Reserved Capacity offers significant savings over the normal price of DynamoDB provisioned throughput capacity.
Amazon ElastiCache Reserved Nodes: Amazon ElastiCache Reserved Nodes give you the option to make a low, one-time payment for each cache node you want to reserve and, in turn, receive a significant discount on the hourly charge for that node.
Amazon RDS RIs: Like Amazon EC2 RIs, Amazon RDS RIs can be purchased using No Upfront, Partial Upfront, or All Upfront terms. All Reserved Instance types are available for Aurora, MySQL, MariaDB, PostgreSQL, Oracle, and SQL Server database engines.
Amazon Redshift Reserved Nodes: If you intend to keep an Amazon Redshift cluster running continuously for a prolonged period, you should consider purchasing reserved-node offerings. These offerings provide significant savings over on-demand pricing, but they require you to reserve compute nodes and commit to paying for those nodes for either a 1- or 3-year duration.
Incorrect options:
Amazon DocumentDB - Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. As a document database, Amazon DocumentDB makes it easy to store, query, and index JSON data.

Which of the following statement is correct regarding the AWS pricing policy for data transfer charges into or out of an AWS Region?
A. Only outbound data transfer is charged
B. Niether inbound nor outbound data transfers are charged
C. Only inbound data transfer is charged
D. Both inbound and outbound data transfers are charged
A. Only outbound data transfer is charged
Explanation
Correct option:
Only outbound data transfer is charged
One of the main benefits of cloud services is the ability it gives you to optimize costs to match your needs, even as those needs change. AWS services do not have complex dependencies or licensing requirements, so you can get exactly what you need to build innovative, cost-effective solutions using the latest technology.
There are three fundamental drivers of cost with AWS: compute, storage, and outbound data transfer. These characteristics vary somewhat, depending on the AWS product and pricing model you choose. Outbound data to the internet from all AWS regions is billed at region-specific, tiered data transfer rates. Inbound data transfer into all AWS regions from the internet is free.
Incorrect options:
Only inbound data transfer is charged
Both inbound data transfer and outbound data transfer are charged
Neither inbound nor outbound data transfer are charged
These three options contradict the explanation provided above, so these options are incorrect.

Which Amazon Elastic Compute Cloud (Amazon EC2) pricing model is the most cost-effective and flexible with no requirement for a long term resource commitment or upfront payment but still guarantees that instance would not be interrupted?
A. On-Demand Instance
B. Reserved Instance (RI)
C. Dedicated Host
D. Spot Instance
A. On-Demand Instance
Explanation
Correct option:
On-Demand Instance - An On-Demand Instance is an instance that you use on-demand. You have full control over its lifecycle — you decide when to launch, stop, hibernate, start, reboot, or terminate it. There is no long-term commitment required when you purchase On-Demand Instances. There is no upfront payment and you pay only for the seconds that your On-Demand Instances are running. The price per second for running an On-Demand Instance is fixed. On-demand instances cannot be interrupted.
EC2 Pricing Options Overview: via - https://aws.amazon.com/ec2/pricing/
Incorrect options:
Reserved Instance (RI) - Reserved Instance (RI) provides you with significant savings on your Amazon EC2 costs compared to On-Demand Instance pricing. Reserved Instances (RI) are not physical instances, but rather a billing discount applied to the use of On-Demand Instances in your account. You can purchase a Reserved Instance (RI) for a one-year or three-year commitment, with the three-year commitment offering a bigger discount. You will be charged for the entire duration, irrespective of your usage. So this option is not correct for the given use-case.
Spot Instance - A Spot Instance is an unused EC2 instance that is available for less than the On-Demand price. Because Spot Instances enable you to request unused EC2 instances at steep discounts, you can lower your Amazon EC2 costs significantly. Spot Instances are well-suited for data analysis, batch jobs, background processing, and optional tasks. These can be terminated at short notice, so these are not suitable for critical workloads that need to run at a specific point in time. So this option is not correct for the given use-case.
Dedicated Host - Amazon EC2 Dedicated Host allows you to use your eligible software licenses from vendors such as Microsoft and Oracle on Amazon EC2 so that you get the flexibility and cost-effectiveness of using your licenses, but with the resiliency, simplicity, and elasticity of AWS. An Amazon EC2 Dedicated Host is a physical server fully dedicated for your use, so you can help address corporate compliance requirement. A Dedicated Host is not cost-efficient compared to an On-Demand instance. So this option is not correct.

A. Create separate AWS accounts for development and production environments to receive separate invoices
B. Use AWS Cost Explorer to create separate invoices for development and production environments
C. Use AWS Organizations to create separate invoices for development and production environments
D. Tag all resources in the AWS account as either development or production. Then use the tags to create separate invoices
A. Create separate AWS accounts for development and production environments to receive separate invoices
Explanation
Correct option:
Create separate AWS accounts for development and production environments to receive separate invoices
Every AWS account provides its own invoice end of the month. You can get separate invoices for development and production environments by setting up separate AWS accounts for each environment.
Incorrect options:
Use AWS Organizations to create separate invoices for development and production environments - AWS Organizations helps you to centrally manage billing; control access, compliance, and security; and share resources across your AWS accounts. Using AWS Organizations, you can automate account creation, create groups of accounts to reflect your business needs, and apply policies for these groups for governance. You can also simplify billing by setting up a single payment method for all of your AWS accounts. AWS Organizations is available to all AWS customers at no additional charge.
AWS Organizations cannot create separate invoices for development and production environments, rather, AWS Organizations helps you to centrally manage billing.
Tag all resources in the AWS account as either development or production. Then use the tags to create separate invoices - You cannot create separate invoices based on tags.
Use AWS Cost Explorer to create separate invoices for development and production environments - AWS Cost Explorer lets you explore your AWS costs and usage at both a high level and at a detailed level of analysis, and empowering you to dive deeper using several filtering dimensions (e.g., AWS Service, Region, Linked Account). AWS Cost Explorer cannot create separate invoices for development and production environments.

Which of the following statements are true about Cost Allocation Tags in AWS Billing? (Select two)
A. You must activate both AWS generated tags and user-defined tags separately before they can appear in Cost Explorer or on a cost allocation report
B. Only user-defined tags need to be activated before they can appear in Cost Explorer or on cost allocation report
C. Tags help in organizing resources and are mandatory configuration item to run reports
D. For each resource, each tag key must be unique, but can have multiple values
E. For each resource, each tag key must be unique, adn ech tag key can have only one value
A. You must activate both AWS generated tags and user-defined tags separately before they can appear in Cost Explorer or on a cost allocation report
E. For each resource, each tag key must be unique, adn ech tag key can have only one value
Explanation
Correct options:
For each resource, each tag key must be unique, and each tag key can have only one value
You must activate both AWS generated tags and user-defined tags separately before they can appear in Cost Explorer or on a cost allocation report
A Cost Allocation Tag is a label that you or AWS assigns to an AWS resource. Each tag consists of a key and a value. For each resource, each tag key must be unique, and each tag key can have only one value. You can use tags to organize your resources, and cost allocation tags to track your AWS costs on a detailed level.
AWS provides two types of cost allocation tags, an AWS generated tags and user-defined tags. AWS defines, creates, and applies the AWS generated tags for you, and you define, create, and apply user-defined tags. You must activate both types of tags separately before they can appear in Cost Explorer or on a cost allocation report.
AWS Cost Allocation Tags Overview: via - https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/cost-alloc-tags.html
Incorrect options:
Tags help in organizing resources and are a mandatory configuration item to run reports - Tags definitely help organize resources as per an organization’s requirement; they are not mandatory though.
For each resource, each tag key must be unique, but can have multiple values - For each resource, each tag key must be unique, and each tag key can have only one value.
Only user-defined tags need to be activated before they can appear in Cost Explorer or on a cost allocation report - As explained above, both kinds of tags (user-defined and AWS generated) need to be activated separately before they can appear in report generation.

A customer is running a comparative study of pricing models of Amazon EFS and Amazon Elastic Block Store (Amazon EBS) that are used with the Amazon EC2 instances that host the application. Which of the following statements are correct regarding this use-case? (Select two)
A. Amazon Elastic Compute Cloud (Amazon EC2) data transfer charge will apply for all Amazon Elastic Block Store (Amazon EBS) direct APIs for Snapshots
B. You will pay a fee time you read from or write data stored on the Amazon Elastic FIle System (Amazon EFS) - Infrequent Access storage class
C. With AWS Backup, you pay only for Amazon Elastic File System (Amazon EFS) backup storage you use in a month, you need not pay for restoring data
D. Amazon Elastic Block Store (Amazon EBS) Snapshot are stored incrementally, which means you are billed only for the changed block stored
E. Amazon Elastic Block Store (Amazon EBS) Snaphot storage pricing is based on the amount of space your data consumes in Amazon Elastic Block Store (Amazon EBS)
B. You will pay a fee time you read from or write data stored on the Amazon Elastic FIle System (Amazon EFS) - Infrequent Access storage class
D. Amazon Elastic Block Store (Amazon EBS) Snapshot are stored incrementally, which means you are billed only for the changed block stored
Explanation
Correct options:
You will pay a fee each time you read from or write data stored on the Amazon Elastic File System (Amazon EFS) - Infrequent Access storage class
Amazon Elastic File System (Amazon EFS) - Infrequent Access storage class is cost-optimized for files accessed less frequently. Data stored on the Amazon Elastic File System (Amazon EFS) - Infrequent Access storage class costs less than Standard and you will pay a fee each time you read from or write to a file.
Amazon Elastic Block Store (Amazon EBS) Snapshots are stored incrementally, which means you are billed only for the changed blocks stored
Amazon EBS Snapshots are a point in time copy of your block data. For the first snapshot of a volume, Amazon EBS saves a full copy of your data to Amazon S3. Amazon EBS Snapshots are stored incrementally, which means you are billed only for the changed blocks stored.
Incorrect options:
Amazon Elastic Compute Cloud (Amazon EC2) data transfer charges will apply for all Amazon Elastic Block Store (Amazon EBS) direct APIs for Snapshots - When using Amazon EBS direct APIs for Snapshots, additional Amazon EC2 data transfer charges will apply only when you use external or cross-region data transfers.
Amazon Elastic Block Store (Amazon EBS) Snapshot storage pricing is based on the amount of space your data consumes in Amazon Elastic Block Store (Amazon EBS) - Snapshot storage is based on the amount of space your data consumes in Amazon S3. Because Amazon EBS does not save empty blocks, it is likely that the snapshot size will be considerably less than your volume size. Copying Amazon EBS snapshots is charged for the data transferred across regions. After the snapshot is copied, standard Amazon EBS snapshot charges apply for storage in the destination region.
With AWS Backup, you pay only for the amount of Amazon Elastic File System (Amazon EFS) backup storage you use in a month, you need not pay for restoring this data - To back up your Amazon EFS file data you can use AWS Backup, a fully-managed backup service that makes it easy to centralize and automate the back up of data across AWS services. With AWS Backup, you pay only for the amount of backup storage you use and the amount of backup data you restore in the month. There is no minimum fee and there are no set-up charges.
