T/F: Azure Resource Manager (ARM) is a centralized management layer for managing all Azure
resources?
True

T/F: Operational Expenditure (OpEx) is the money paid for the products and services as you
use them (pay-as-you-go).
True
Operational Expenditure (OpEx) is the money paid for the products and services as you use
them (pay-as-you-go).
Q: Examples of Capital Expenditure (CapEx) computing costs are?
Provide six (6) categories.
○ Server costs - server clustering, redundant power supplies, and uninterruptible power
supplies.

T/F: Each service in the cloud has multiple consumption-based metrics which are combined to
determine the cost of the service.
True
Each service in the cloud has multiple consumption-based metrics which are combined to
determine the cost of the service.
Q: Virtual machines are an example of which of the following:
○ Software as a Service (SaaS)
○ Platform as a Service (PaaS)
○ Infrastructure as a Service (IaaS)
Virtual machines are an example of Infrastructure as a Service (IaaS).
Cloud providers manage the physical infrastructure (aka hardware) and virtualization while
customers maintain everything else, including OS and app updates, security configurations, etc.
Q: SQL Server installed on a virtual machine is an example of which of the following:
○ Software as a Service (SaaS)
○ Platform as a Service (PaaS)
○ Infrastructure as a Service (IaaS)

○ Software as a Service (SaaS)
○ Platform as a Service (PaaS)
○ Infrastructure as a Service (IaaS)
Azure SQL Database is an example of Platform as a Service (PaaS) because Microsoft maintains
the underlying SQL Server and VM. Customers need only create tables, upload data, and
configure their apps to use the database.
Microsoft Office 365 and OneDrive are examples of which of the following:
○ Software as a Service (SaaS)
○ Platform as a Service (PaaS)
○ Infrastructure as a Service (IaaS)
Microsoft Office 365 and OneDrive are examples of Software as a Service (SaaS). Customers
