Elasticity refers to the ability to scale resources as needed, such as during business hours, to ensure that an application can keep up with demand, and then reducing the available resources during off-peak hours. Agility refers to the ability to deploy new applications and services quickly. High availability refers to the ability to ensure that a service or application remains available in the event of a failure. Geo-distribution makes a service or application available in multiple geographic locations that are typically close to your users.

SaaS is software that is centrally hosted and managed for you and your users or customers. Usually, one version of the application is used for all customers, and it is licensed through a monthly or annual subscription. PaaS and IaaS use a consumption-based model, so you only pay for what you use.
SaaS allows users to connect to and use cloud-based apps over the internet. Common examples are email, calendaring, and Office tools, such as Office 365.
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.

ARM is the deployment and management service for Azure. It provides a management layer that enables you to create, update, and delete resources in an Azure account.

ARM templates define an application's infrastructure requirements for a repeatable deployment that is done in a consistent manner. A validation step ensures that all resources can be created in the proper order based on dependencies, in parallel and idempotent.

This answer is incorrect.
Computing resources are used exclusively by users from one organization.
This answer is incorrect.
Hardware is physically located in an organization's on-site datacenter.
In a public cloud, services are offered over the internet and are available to anyone who wants to purchase them. A private cloud is limited to a single organization. Cloud resources, such as servers and storage, are owned and operated by a third-party cloud service provider and delivered over the internet. A private cloud consists of computing resources used exclusively by users from one business or organization.
You can link virtual networks together by using virtual network peering. Peering enables resources in each virtual network to communicate with each other.

Wrong:
identifying lower cost regions
Wrong:
resizing underutilized virtual machines
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.

Scaling horizontally increases compute capacity by adding instances of resources, such as adding virtual machines to the configuration. You scale vertically by adding RAM or CPUs to a virtual machine. Disaster recovery keeps data and other assets safe in the event of a disaster. High availability minimizes downtime when things go wrong.
