AZ-900: Microsoft Azure Fundamentals
To complete the sentence, select the appropriate option in the answer area.
deploy a VPN
pay monthly usage costs
pay to transfer all the website data to Azure.
reduce the number of connections to the website.
Answer is pay monthly usage costs
When migrating a public website to Azure, you need to plan for the pricing model that Azure provides. Azure charges for the usage of resources such as virtual machines, storage, and data transfer. Therefore, you need to plan to pay monthly usage costs for hosting the website on Azure. Deploying a VPN, paying to transfer all the website data to Azure, or reducing the number of connections to the website are not necessarily required for migrating a public website to Azure.
Your company plans to migrate all its data and resources to Azure. The company's migration plan states that only Platform as a Service (PaaS) solutions must be used in Azure. You need to deploy an Azure environment that meets the company migration plan. Solution: You create an Azure App Service and Azure SQL databases. Does this meet the goal?
Yes
No
Answer is Yes
Azure App Service and Azure SQL databases are examples of Azure PaaS solutions. Therefore, this solution does meet the goal.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
One of the major changes that you will face when you move from on-premises cloud to the public cloud is the switch from capital expenditure (buying hardware) to operating expenditure (paying for service as you use it).
OpEx is your operating costs, the expenses to run day-to-day business, like services and consumable items that get used up and are paid for according to use. This includes printer cartridges and paper, electricity, and even yearly services like website hosting or domain registrations. These things are necessary for your business’s success but are not considered major long-term investments like CapEx items.
Box 1: No
With the pay-as-go model, you pay for services as you use them. This is Opex (Operational Expenditure), not CapEx (Captial Expenditure). CapEx is where you pay for something upfront. For example, buying a new physical server.
Box 2: Yes
Paying for electricity for your own datacenter will be classed as OpEx.
Box 3: Yes
Deploying your own datacenter is an example of CapEx. This is because you need to purchase all the infrastructure upfront before you can use it.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
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: No
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. Private cloud means that the physical servers are managed by you. It does not mean that it is disconnected from the Internet.

Your company plans to migrate all its data and resources to Azure.
The company's migration plan states that only Platform as a Service (PaaS) solutions must be used in Azure.
You need to deploy an Azure environment that meets the company migration plan.
Solution: You create an Azure virtual machines, Azure SQL databases, and Azure Storage accounts.
Does this meet the goal?
Yes
No
Answer is No
IaaS is ideal for organizations that need to run legacy applications or need greater control over their infrastructure. Virtual Machines, Virtual Networks, and some Storage Accounts features are infrastructure as a service offered by Azure.
Platform as a service (PaaS) is a complete development and deployment environment in the cloud. 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.

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Box 1: No
Building a data center infrastructure is capital expenditure, not operation expenditure.
Box 2: Yes
OpEx is ongoing costs (costs of operations) such as staff salaries.
Box 2: Yes
OpEx is ongoing costs (costs of operations) such as leasing software. If you purchased software as a one-off purchase, that would be CapEx, but leasing software is ongoing so it's OpEx.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Box 1: No
Box 2: No
Each resource can exist in only one resource group.
Box 3: Yes
Resources from multiple different regions can be placed in a resource group. The resource group only contains metadata about the resources it contains.

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Availability zones expand the level of control you have to maintain the availability of the applications and data on your VMs. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there are a minimum of three separate zones in all enabled regions. The physical separation of Availability Zones within a region protects applications and data from datacenter failures.
With Availability Zones, Azure offers industry best 99.99% VM uptime SLA. By architecting your solutions to use replicated VMs in zones, you can protect your applications and data from the loss of a datacenter. If one zone is compromised, then replicated apps and data are instantly available in another zone.

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
1. No - You can assign service administrators and co-administrators in the Azure Portal but there can only be one account administrator.
2. No - You need an Azure Active Directory account to manage a subscription, not a Microsoft account.
An account is created in the Azure Active Directory when you create the subscription. Further accounts can be created in the Azure Active Directory to manage the subscription
3. No. Resource groups are logical containers for Azure resources. However, resource groups do not contain subscriptions. Subscriptions contain resource groups.

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Box 1: No
A resource can interact with resources in other resource groups.
Box 2: Yes
Deleting the resource group will remove the resource group as well as all the resources in that resource group. This can be useful for the management of resources. For example, a virtual machine has several components (the VM itself, virtual disks, network adapter etc.). By placing the VM in its own resource group, you can delete the VM along with all its associated components by deleting the resource group.
Another example is when creating a test environment. You could place the entire test environment (Network components, virtual machines etc.) in one resource group. You can then delete the entire test environment by deleting the resource group.
Box 3: Yes
Resources from multiple different regions can be placed in a resource group. The resource group only contains metadata about the resources it contains.
