Question #31
Your company has two on-premises servers named SRV01 and SRV02. Developers have created an application that runs on SRV01. The application calls a service on SRV02 by IP address.
You plan to migrate the application on Azure virtual machines (VMs). You have configured two VMs on a single subnet in an Azure virtual network.
You need to configure the two VMs with static internal IP addresses.
What should you do?
  1. A
    Run the New-AzureRMVMConfig PowerShell cmdlet.
  2. B
    Run the Set-AzureSubnet PowerShell cmdlet.
  3. C
    Modify the VM properties in the Azure Management Portal.
  4. D
    Modify the IP properties in Windows Network and Sharing Center.
  5. E
    Run the Set-AzureStaticVNetIP PowerShell cmdlet.

Correct Answer:
E
Specify a static internal IP for a previously created VM
If you want to set a static IP address for a VM that you previously created, you can do so by using the following cmdlets. If you already set an IP address for the
VM and you want to change it to a different IP address, you'll need to remove the existing static IP address before running these cmdlets. See the instructions below to remove a static IP.
For this procedure, you'll use the Update-AzureVM cmdlet. The Update-AzureVM cmdlet restarts the VM as part of the update process. The DIP that you specify will be assigned after the VM restarts. In this example, we set the IP address for VM2, which is located in cloud service StaticDemo.
Get-AzureVM -ServiceName StaticDemo -Name VM2 | Set-AzureStaticVNetIP -IPAddress 192.168.4.7 | Update-AzureVM

Question #32
Your company has an Azure Active Directory (Azure AD) subscription.
You need to deploy five virtual machines (VMs) to your company's virtual network subnet.
The VMs will each have both a public and private IP address. Inbound and outbound security rules for all of these virtual machines must be identical.
Which of the following is the least amount of network interfaces needed for this configuration?
  1. A
    5
  2. B
    10
  3. C
    20
  4. D
    40

Correct Answer:
A
chatbot-img GPT-4o - Answer
Absolutely right, each of the five virtual machines needs only one network interface card (NIC) because a single NIC can be assigned both a public and a private IP address. Azure allows to configure multiple IPs on a single NIC, complying with the subnet's connectivity requirements. To manage identical inbound and outbound security for these VMs efficiently, a network security group (NSG) can be attached directly to each NIC or to the subnet itself. This approach keeps the setup simple with minimized complexity and is aligned with Azure's capability to handle multiple IP addresses on a single NIC.

Question #33
Your company has an Azure Active Directory (Azure AD) subscription.
You need to deploy five virtual machines (VMs) to your company's virtual network subnet.
The VMs will each have both a public and private IP address. Inbound and outbound security rules for all of these virtual machines must be identical.
Which of the following is the least amount of security groups needed for this configuration?
  1. A
    4
  2. B
    3
  3. C
    2
  4. D
    1

Correct Answer:
D
chatbot-img GPT-4o - Answer
For the scenario described, you only need one network security group (NSG) to meet the requirements. As the security rules are identical for all five VMs, a single NSG can be applied to the subnet where all VMs are located. This allows for centralized management of security rules for all VMs in that subnet, simplifying configuration and enforcement of uniform security policies across multiple machines.

Question #34
Your company's Azure subscription includes Azure virtual machines (VMs) that run Windows Server 2016.
One of the VMs is backed up every day using Azure Backup Instant Restore.
When the VM becomes infected with data encrypting ransomware, you decide to recover the VM's files.
Which of the following is TRUE in this scenario?
  1. A
    You can only recover the files to the infected VM.
  2. B
    You can recover the files to any VM within the company's subscription.
  3. C
    You can only recover the files to a new VM.
  4. D
    You will not be able to recover the files.

Correct Answer:
A
chatbot-img GPT-4o - Answer
It's essential to recognize that Azure Backup Instant Restore principally allows for recovery directly back to the original VM to ensure a rapid restoration process. Although user comments imply a flexibility to recover across different VMs within the same subscription, they don't consider the specific context of Instant Restore. Instant Restore's main goal is to provide quick and efficient recovery options specifically tailored to the original environment, which typically involves restoring to the source VM from which the backup was taken. This feature highlights Azure's commitment to swift disaster recovery, by minimizing downtime and operational disruption.

Question #35
Your company's Azure subscription includes Azure virtual machines (VMs) that run Windows Server 2016.
One of the VMs is backed up every day using Azure Backup Instant Restore.
When the VM becomes infected with data encrypting ransomware, you are required to restore the VM.
Which of the following actions should you take?
  1. A
    You should restore the VM after deleting the infected VM.
  2. B
    You should restore the VM to any VM within the company's subscription.
  3. C
    You should restore the VM to a new Azure VM.
  4. D
    You should restore the VM to an on-premise Windows device.

Correct Answer:
B
chatbot-img GPT-4o - Answer
Indeed, you can restore the infected VM to any existing VM within your Azure subscription. This approach leverages Azure's flexibility in managing disk resources, allowing you to overwrite an existing VM's disks with the restored backup data. Moreover, this action avoids the logistical overhead of managing new VMs while ensuring business continuity during a ransomware crisis, effectively mitigating mean time to recovery (MTTR).

Question #36
You administer a solution in Azure that is currently having performance issues.
You need to find the cause of the performance issues pertaining to metrics on the Azure infrastructure.
Which of the following is the tool you should use?
  1. A
    Azure Traffic Analytics
  2. B
    Azure Monitor
  3. C
    Azure Activity Log
  4. D
    Azure Advisor

Correct Answer:
B
Metrics in Azure Monitor are stored in a time-series database which is optimized for analyzing time-stamped data. This makes metrics particularly suited for alerting and fast detection of issues.

Question #37
Your company has an Azure subscription that includes a Recovery Services vault.
You want to use Azure Backup to schedule a backup of your company's virtual machines (VMs) to the Recovery Services vault.
Which of the following VMs can you back up? Choose all that apply.
  1. A
    VMs that run Windows 10.
  2. B
    VMs that run Windows Server 2012 or higher.
  3. C
    VMs that have NOT been shut down.
  4. D
    VMs that run Debian 8.2+.
  5. E
    VMs that have been shut down.

Correct Answer:
ABCDE
Azure Backup supports backup of 64-bit Windows server operating system from Windows Server 2008.
Azure Backup supports backup of 64-bit Windows 10 operating system.
Azure Backup supports backup of 64-bit Debian operating system from Debian 7.9+.
Azure Backup supports backup of VM that are shutdown or offline.
