Question No : 1
HOTSPOT
You have an Azure subscription named Subscroption1.
In Subscription1, you create an alert rule named Alert1.
The Alert1 action group is configured as shown in the following exhibit.



Alert1 alert criteria is triggered every minute.
Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic. NOTE: Each correct selection is worth one point. Hot Area:



正解:


Explanation:
Box 1: 60
One alert per minute will trigger one email per minute.
Box 2: 12
No more than 1 SMS every 5 minutes can be send, which equals 12 per hour.
Note: Rate limiting is a suspension of notifications that occurs when too many are sent to a particular phone number, email address or device. Rate limiting ensures that alerts are manageable and actionable.
The rate limit thresholds are:
- SMS: No more than 1 SMS every 5 minutes.
- Voice: No more than 1 Voice call every 5 minutes.
- Email: No more than 100 emails in an hour.
- Other actions are not rate limited.

Question No : 2
DRAG DROP
You create an Azure Migrate project named Testis in a resource named test-migration. You need to discover which on-premises virtual machines to assess for migration.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.



正解:


Explanation:
Step 1: Download the OVA file for the collection appliance
Azure Migrate uses an on-premises VM called the collector appliance, to discover information about your on-premises machines. To create the appliance, you download a setup file in Open Virtualization Appliance (.ova) format, and import it as a VM on your on-premises vCenter Server.
Step 2: Create a migration group in the project
For the purposes of assessment, you gather the discovered VMs into groups. For example, you might group VMs that run the same application. For more precise grouping, you can use dependency visualization to view dependencies of a specific machine, or for all machines in a group and refine the group.
Step 3: Create an assessment in the project
After a group is defined, you create an assessment for it.

Question No : 3
You have an Azure subscription that contains 100 virtual machines.
You regularly create and delete virtual machines.
You need to identify unattached disks that can be deleted.
What should you do?

正解:
Explanation:
You can find unused disks in the Azure Storage Explorer console. Once you drill down to the Blob containers under a storage account, you can see the lease state of the residing VHD (the lease state determines if the VHD is being used by any resource) and the VM to which it is leased out. If you find that the lease state and the VM fields are blank, it means that the VHD in question is unused.
Note: The ManagedBy property stores the Id of the VM to which Managed Disk is attached to. If the ManagedBy property is $null then it means that the Managed Disk is not attached to a VM

Question No : 4
You have an on-premises network that contains a Hyper-V host named Host1. Host1 runs Windows Server 2016 and hosts 10 virtual machines that run Windows Server 2016.
You plan to replicate the virtual machines to Azure by using Azure Site recovery.
You create a Recovery Services vault named ASR1 and Hyper-V site named Site1.
You need to add Host1 to ASR1.
What should you do?

正解:
Explanation:
Download the Vault registration key. You need this when you install the Provider. The key is valid for five days after you generate it.
Install the Provider on each VMM server. You don't need to explicitly install anything on Hyper-V hosts.
Incorrect Answers:
B, D: Use the Vault Registration Key, not the storage account key.

Question No : 5
HOTSPOT
You have an Azure Migrate project that has the following assessment properties:
Target location: East US
Storage redundancy: Locally redundant.
Comfort factor: 2.0
Performance history: 1 month
Percentile utilization: 95th
Pricing tier: Standard
Offer: Pay as you go
You discover the following two virtual machines:
A virtual machine named VM1 that runs Windows Server 2016 and has 10 CPU cores at 20 percent utilization
A virtual machine named VM2 that runs Windows Server 2012 and has four CPU cores at 50 percent utilization
How many CPU cores will Azure Migrate recommend for each virtual machine? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.



正解:


Explanation:
Box 2: 4
4 *0.50 * 0.95* 2 = 3.8
Note: The number of cores in the machines must be equal to or less than the maximum number of cores (128 cores) supported for an Azure VM.
If performance history is available, Azure Migrate considers the utilized cores for comparison. If a comfort factor is specified in the assessment settings, the number of utilized cores is multiplied by the comfort factor.
If there's no performance history, Azure Migrate uses the allocated cores, without applying the comfort factor.

You manage a virtual network named Vnet1 that is hosted in the West US Azure region. VNet hosts two virtual machines named VM1 and VM2 run Windows Server. You need to inspect all the network traffic from VM1 to VM2 for a period of three hours. Solution: From Azure Network Watcher, you create a connection monitor. Does this meet the goal?

正解:
Explanation:
Azure Network Watcher provides tools to monitor, diagnose, view metrics, and enable or disable logs for resources in an Azure virtual network. Capture packets to and from a VM Advanced filtering options and fine-tuned controls, such as the ability to set time and size limitations, provide versatility. The capture can be stored in Azure Storage, on the VM's disk, or both. You can then analyze the capture file using several standard network capture analysis tools.
Network Watcher variable packet capture allows you to create packet capture sessions to track traffic to and from a virtual machine. Packet capture helps to diagnose network anomalies both reactively and proactivity.

HOTSPOT
You need to implement App2 to meet the application? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.



正解:


Explanation:
Box 1: Standard
Not Shared: A Shared plan does not support Always on.
Box 2: Always on
If your function app is on the Consumption plan, there can be up to a 10-minute delay in processing new blobs if a function app has gone idle. To avoid this cold-start delay, you can switch to an App Service plan with Always On enabled, or use a different trigger type.
Scenario: A newly developed API must be implemented as an Azure function named App2. App2 will use a blob storage trigger. App2 must process new blobs immediately.
App2 must be able to connect directly to the private IP addresses of the Azure virtual machines. App2 will be deployed directly to an Azure virtual network.
The cost of App1 and App2 must be minimized.
