  • Azure Service Health

You can drill down to the affected services, regions, and details to show how an event will affect you and what you must do. Most of these events occur without any impact to you and will not be shown. In a rare case that a reboot is required, Service Health allows you to choose when to perform the maintenance to minimize the downtime

Question 97

• What are two characteristics of the public cloud deployment model? Each correct answer presents a complete solution.
  • Servers and storage are owned and operated by a third-party cloud service provider.
  • Services are offered over the internet and are available to anyone who wants to purchase them.

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.
