   Explanation: 
   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.

4. HOTSPOT

   For each of the following statements, select Yes if the statement is true. Otherwise, select No.

   NOTE: Each correct selection is worth one point.

   

   

   Explanation:

   Box 1: No
   A subscription can have multiple administrators, but there can only be one account administrator.

   Box 2: Yes
   An Azure subscription is linked to a single account, the one that was used to create the subscription and is used for billing purposes. You can have more than one subscription.

   Box 3: No
   A subscription can contain multiple resource groups but a resource group can only belong to one subscription. Resource groups can contain multiple resources.

5. HOTSPOT

   To complete the sentence, select the appropriate option in the answer area.

   

   

   Explanation: 
   A region is a set of data centres deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network.
   Microsoft Azure currently has 55 regions worldwide.
   Regions are divided into Availability Zones. Availability Zones are physically separate locations within an Azure region. Each Availability Zone is made up of one or more datacenters equipped with independent power, cooling, and networking.

6. HOTSPOT

   For each of the following statements, select Yes if the statement is true. Otherwise, select No.

   NOTE: Each correct selection is worth one point.

   

   

7. You plan to deploy several Azure virtual machines.

   You need to ensure that the services running on the virtual machines remain available if a single data center fails.

   What are two possible solutions? Each correct answer presents a complete solution.

   • Deploy the virtual machines to two or more availability zones.
   • Deploy the virtual machines to two or more resource groups.
   • Deploy the virtual machines to a scale set.
   • Deploy the virtual machines to two or more regions.

8. HOTSPOT

   To complete the sentence, select the appropriate option in the answer area.

   

   

   Explanation:

   Azure automatically routes traffic between subnets in a virtual network. Therefore, all virtual machines in a virtual network can connect to the other virtual machines in the same virtual network. Even if the virtual machines are on separate subnets within the virtual network, they can still communicate with each other.

   To ensure that a virtual machine cannot connect to the other virtual machines, the virtual machine must be deployed to a separate virtual network.

    After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

    You have an Azure environment. You need to create a new Azure virtual machine from a tablet that runs the Android operating system.

    Solution: You use PowerShell in Azure Cloud Shell.

    Does this meet the goal?

    • Yes 
    • No
    Explanation:

    Azure Cloud Shell is a browser-based shell experience to manage and develop Azure resources.

    Cloud Shell offers a browser-accessible, pre-configured shell experience for managing Azure resources without the overhead of installing, versioning, and maintaining a machine yourself.

    Being browser-based, Azure Cloud Shell can be run on a browser from a tablet that runs the Android operating system.

    Solution: You use the PowerApps portal.

    Does this meet the goal?

    • Yes
    • No 
    Explanation:

    PowerApps lets you quickly build business applications with little or no code. It is not used to create Azure virtual machines. Therefore, this solution does not meet the goal.

    PowerApps Portals allow organizations to create websites which can be shared with users external to their organization either anonymously or through the login provider of their choice like LinkedIn, Microsoft Account, other commercial login providers.
