Practice Assessment for Exam AZ-900: Microsoft Azure Fundamentals Flashcards
Which two factors affect Azure costs? Each correct answer presents a complete solution.
Select all answers that apply.
availability zone selection
date and time of use
resource location
resource usage
resource location
resource usage
Explanation:
Usage meters, such as CPU time, disk size, and write operations, are used to calculate your bill for an Azure resource. Deleting or deallocating a resource means that you will no longer be billed for it. Different regions can have different associated prices. Resources cost the same no matter the time of day or the day of the week.
Which are two common scenarios for using resource tags? Each correct answer presents a complete solution.
Select all answers that apply.
associating costs with different environments
categorizing costs by department
identifying lower cost regions
resizing underutilized virtual machines
associating costs with different environments
categorizing costs by department
Explanation:
You can use tags to categorize costs by department, such as human resources, marketing, or finance, or by environment, such as test or production. Resizing underutilized virtual machines is a good cost saving measure and provisioning resources in lower cost regions is a good practice, but resource tags do not help with this.

Select only one answer.
Azure Advisor
Azure Policy
resource locks
resource tags
Azure Policy
Explanation:
Azure Policy is a service in Azure that enables you to create, assign, and manage policies that control or audit resources. These policies enforce different rules across all resource configurations so that the configurations stay compliant with corporate standards.
You need to recommend a solution for Azure virtual machine deployments. The solution must enforce company standards on the virtual machines.

What are two characteristics of a consumption-based model? Each correct answer presents a complete solution.
Select all answers that apply.
high capital expenditures
no upfront costs
requires the purchase and management of the physical infrastructure
