Which of the following EC2 services can be used without charge under the Free Tier? A. Any single EC2 instance type as long as it runs for less than one hour per day B. Any single EC2 instance type as long as it runs for less than 75 hours per month C. A single t2.micro EC2 instance type instance for 750 hours per month D. t2.micro EC2 instance type instances for a total of 750 hours per month	D. Only the t2.micro instance type is Free Tier–eligible, and any combination of t2.micro instances can be run up to a total of 750 hours per month.

Which of the following is likely to be an accurate source of AWS pricing information? A. Wikipedia pages relating to a particular service B. The AWS Command Line Interface (AWS CLI) C. AWS online documentation relating to a particular service D. The AWS Total Cost of Ownership Calculator	C. Wikipedia pages aren’t updated or detailed enough to be helpful in this respect. The AWS CLI isn’t likely to have much (if any) pricing information. The TCO Calculator shouldn’t be used for specific and up-to-date information about service pricing.
Which of the following will probably not affect the pricing for an AWS service? A. Requests for raising the available service limit B. AWS Region C. The volume of data saved to an S3 bucket D. The volume of data egress from an Amazon Glacier vault	A. Pricing will normally change based on the volume of service units you consume and, often, between AWS Regions.

Which of the following AWS Total Cost of Ownership Calculator parameters is likely to have the greatest impact on cost? A. Currency B. AWS Region C. Guest OS D. Number of servers	D. The currency you choose to use will have little impact on price—it’s all relative, of course. The guest OS and region will make a difference, but it’s relatively minor.
Which of the following AWS documentation URLs points to the page containing an up-todate list of service limits? A. https://docs.aws.amazon.com/general/latest/gr/limits.html B. https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html C. https://aws.amazon.com/general/latest/gr/aws_service_limits.html D. https://docs.aws.amazon.com/latest/gr/aws_service_limits.html	B. The correct URL is https://docs.aws.amazon.com/general/latest/gr/ aws_service_limits.html.
Which of the following best describes one possible reason for AWS service limits? A. To prevent individual customers from accidentally launching a crippling level of resource consumption B. To more equally distribute available resources between customers from different regions C. To allow customers to more gradually increase their deployments D. Because there are logical limits to the ability of AWS resources to scale upward	A. Resource limits exist only within individual regions; the limits in one region don’t impact another. There’s no logistical reason that customers can’t scale up deployments at any rate. There are, in fact, no logical limits to the ability of AWS resources to scale upward.
Is it always possible to request service limit increases from AWS? A. Yes. All service limits can be increased. B. No. A limit can never be increased. C. Service limits are defaults. They can be increased or decreased on demand. D. No. Some service limits are hard.	D. While most service limits are soft and can be raised on request, there are some service limits that are absolute.
Which is the best place to get a quick summary of this month’s spend for your account? A. Budgets B. Cost Explorer C. Cost and usage reports D. Billing & Cost Management Dashboard	D.

What is the main goal for creating a Usage budget type (in AWS Budgets)? A. To correlate usage per unit cost to understand your account cost efficiency B. To track the status of any active reserved instances on your account C. To track particular categories of resource consumption D. To monitor costs being incurred against your account	C. Reservation budgets track the status of any active reserved instances on your account. Cost budgets monitor costs being incurred against your account. There is no budget type that correlates usage per unit cost to understand your account cost efficiency.
Which of the following is not a setting you can configure in a Cost budget? A. Period (monthly, quarterly, etc.) B. Instance type C. Start and stop dates D. Owner (username of resource owner)	D. You can configure the period, instance type, and start/stop dates for a budget, but you can’t filter by resource owner.
What is the main difference between the goals of Cost Explorer and of cost and usage reports? A. Cost Explorer displays visualizations of high-level historical and current account costs, while cost and usage reports generate granular usage reports in CSV format. B. Cost and usage reports display visualizations of high-level historical and current account costs, while Cost Explorer generates granular usage reports in CSV format. C. Cost Explorer lets you set alerts that are triggered by billing events, while cost and usage reports help you visualize system events. D. Cost and usage reports are meant to alert you to malicious intrusions, while Cost Explorer displays visualizations of high-level historical and current account costs.	A. Billing events aren’t triggers for alerts. Nothing in this chapter discusses intrusion events.
What is the purpose of cost allocation tags? A. To associate spend limits to automatically trigger resource shutdowns when necessary B. To help you identify the purpose and owner of a particular running resource to better understand and control deployments C. To help you identify resources for the purpose of tracking your account spending D. To visually associate account events with billing periods	C. Tags are passive, so they can’t automatically trigger anything. Resource tags—not cost allocation tags—are meant to help you understand and control deployments. Tags aren’t associated with particular billing periods.
