Question 851
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Statement 1: To achieve a hybrid cloud model, a company must always migrate from a private cloud model: No
Statement 2: A company can extend the capacity of its internal network by using the public cloud: Yes
Statement 3: In a public cloud model, only guest users at your company can access the resources in the cloud: No
Explanation
Statement 1: To achieve a hybrid cloud model, a company must always migrate from a private cloud model: No
It is not true that a company must always migrate from a private cloud model to implement a hybrid cloud. You could start with a public cloud and then combine that with an on-premise infrastructure to implement a hybrid cloud.
Statement 2: A company can extend the capacity of its internal network by using the public cloud: Yes
A company can extend the capacity of its internal network by using the public cloud. This is very common. When you need more capacity, rather than pay out for new on-premises infrastructure, you can configure a cloud environment and connect your on-premises network to the cloud environment by using a VPN.
Statement 3: In a public cloud model, only guest users at your company can access the resources in the cloud: No
It is not true that only guest users can access cloud resources. You can give anyone with an account in Azure Active Directory access to the cloud resources. There are many authentication scenarios but a common one is to replicate your on-premises Active Directory accounts to Azure Active Directory and provide access to the Azure Active Directory accounts. Another commonly used authentication method is ‘Federation’ where authentication for access to cloud resources is passed to another authentication provider such as an on-premises Active Directory.
Question 852
You have an on-premises network that contains 100 servers.
You need to recommend a solution that provides additional resources to your users. The solution must minimize capital and operational expenditure costs.
What should you include in the recommendation?
A. a complete migration to the public cloud
B. an additional data center
C. a private cloud
*D. a hybrid cloud
Explanation
A hybrid cloud is a combination of a private cloud and a public cloud.
Capital expenditure is the spending of money up-front for infrastructure such as new servers.
With a hybrid cloud, you can continue to use the on-premises servers while adding new servers in the public cloud (Azure for example). Adding new servers in Azure minimizes the capital expenditure costs as you are not paying for new servers as you would if you deployed new server on-premises.
Incorrect Answers:
A: A complete migration of 100 servers to the public cloud would involve a lot of operational expenditure (the cost of migrating all the servers).
B: An additional data center would involve a lot of capital expenditure (the cost of the new infrastructure).
C: A private cloud is hosted on on-premises servers to this would involve a lot of capital expenditure (the cost of the new infrastructure to host the private cloud).
Question 853
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Statement 1: Azure provides flexibility between capital expenditure (CapEx) and operational expenditure (OpEx): Yes
Statement 2: If you create two Azure virtual machines that use the B2S size, each virtual machine will always generate the same monthly costs: No
Statement 3: When an Azure virtual machine is stopped, you continue to pay storage costs associated to the virtual machine: Yes
Explanation
Statement 1: Azure provides flexibility between capital expenditure (CapEx) and operational expenditure (OpEx): Yes
Traditionally, IT expenses have been considered a Capital Expenditure (CapEx). Today, with the move to the cloud and the pay-as-you-go model, organizations have the ability to stretch their budgets and are shifting their IT CapEx costs to Operating Expenditures (OpEx) instead. This flexibility, in accounting terms, is now an option due to the “as a Service” model of purchasing software, cloud storage and other IT related resources.
Statement 2: If you create two Azure virtual machines that use the B2S size, each virtual machine will always generate the same monthly costs: No
Two virtual machines using the same size could have different disk configurations. Therefore, the monthly costs could be different.
Statement 3: When an Azure virtual machine is stopped, you continue to pay storage costs associated to the virtual machine: Yes
When an Azure virtual machine is stopped, you don’t pay for the virtual machine. However, you still pay for the storage costs associated to the virtual machine. The most common storage costs are for the disks attached to the virtual machines. There are also other storage costs associated with a virtual machine such as storage for diagnostic data and virtual machine backups.
Question 854
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Statement 1: A platform as a service (PaaS) solution that hosts web apps in Azure provides full control of the operating systems that host applications: No
Statement 2: A platform as a service (PaaS) solution that hosts web apps in Azure web apps in Azure provides the ability to scale the platform automatically: Yes
Statement 3: A platform as a service (PaaS) solution that hosts web apps in Azure provides professional development services to continuously add features to custom applications: Yes
Explanation
Statement 1: A platform as a service (PaaS) solution that hosts web apps in Azure provides full control of the operating systems that host applications: 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.
Statement 2: A platform as a service (PaaS) solution that hosts web apps in Azure web apps in Azure provides the ability to scale the platform automatically: 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.
Statement 3: A platform as a service (PaaS) solution that hosts web apps in Azure provides professional development services to continuously add features to custom applications: Yes
PaaS provides a framework that developers can build upon to develop or customize cloud-based applications. PaaS development tools can cut the time it takes to code new apps with pre-coded application components built into the platform, such as workflow, directory services, security features, search and so on.
