   Explanation

   The answer is A. Yes Using Infrastructure as a Service (IaaS) is the appropriate solution for deploying Azure virtual machines. IaaS provides you with the flexibility to create, manage, and configure virtual machines in the cloud while still maintaining control over the underlying infrastructure, including operating systems, networking, and storage.

   • Bprivate cloud only
   • Cprivate cloud, hybrid cloud and public cloud
   • Dhybrid cloud only

   Answer: A

   Explanation

   I assume that when they say 'deploy', they mean actually racking a server yourself. You don't do this with Azure dedicated hosts so the answer is A.

   Explanation

   Box 1: Public Cloud - With a public cloud, there is no capital expenditure on server hardware etc. You only pay for cloud resources that you use as you use them. Box 2: Private Cloud - A private cloud exists on premises, so you have complete control over security. Box 3: Hybrid Cloud - A hybrid cloud is a mix of public cloud resources and on-premises resources. Therefore, you have a choice to use either.

   Answer: See figure below

   Explanation

   Box 1: No - You cannot add physical servers to the public cloud. You can only deploy virtual servers in the public cloud. You can extend a private cloud by deploying virtual servers in a public cloud. This would create a hybrid cloud. Box 2: Yes - A hybrid cloud is a combination of a private cloud and public cloud. Therefore, to create a hybrid cloud, you must deploy resources to a public cloud. Box 3: No. It is not true that a private cloud must be disconnected from the Internet. Private clouds can be and most commonly are connected to the Internet. ג€Private cloudג€ means that the physical servers are managed by you. It does not mean that it is disconnected from the Internet. Reference: https://azure.microsoft.com/en-gb/overview/what-are-private-public-hybrid-clouds/

   Explanation

   Box 1: No - A PaaS solution does not provide access to the operating system. The Azure Web Apps service provides an environment for you to host your web applications. Behind the scenes, the web apps are hosted on virtual machines running IIS. However, you have no direct access to the virtual machine, the operating system or IIS. Box 2: Yes - Box 3: Yes - A PaaS solution that hosts web apps in Azure does provide the ability to scale the platform automatically. This is known as autoscaling. Behind the scenes, the web apps are hosted on virtual machines running IIS. Autoscaling means adding more load balanced virtual machines to host the web apps.

   Explanation

   I am sorry. But your friend is wrong. https://azure.microsoft.com/en-us/resources/cloud-computing-dictionary/what-is-iaas/ https://azure.microsoft.com/en-us/resources/cloud-computing-dictionary/what-is-paas/ Like IaaS, PaaS includes infrastructure—servers, storage, and networking—but also middleware, development tools, business intelligence (BI) services, database management systems, and more. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing, and updating.
