You are developing an Azure messaging solution.
You need to ensure that the solution that meets the following requirements:
• Provide transactional support
• Provide duplicate detection.
• Store the messages for an unlimited period of time
Which two technologies will meet the requirements? Each correct answer presents a complete solution NOTE Each correct selection is worth one point.

1. A. Azure Service Bus Queue
2. B. Azure Storage Queue
3. C. Azure Service Bus Topic D Azure Event Hub

Correct Answer: AC
The Azure Service Bus Queue and Topic has duplicate detection.
Enabling duplicate detection helps keep track of the application-controlled MessageId of all messages sent into a queue or topic during a specified time window.

You need to ensure receipt processing occurs correctly. What should you do?

1. A. Use blob properties to prevent concurrency problems
2. B. Use blob SnapshotTime to prevent concurrency problems
3. C. Use blob metadata to prevent concurrency problems
4. D. Use blob leases to prevent concurrency problems

Correct Answer: D
You can create a snapshot of a blob. A snapshot is a read-only version of a blob that's taken at a point in time. Once a snapshot has been created, it can be read, copied, or deleted, but not modified. Snapshots provide a way to back up a blob as it appears at a moment in time.
Scenario: Processing is performed by an Azure Function that uses version 2 of the Azure Function runtime. Once processing is completed, results are stored in Azure Blob Storage and an Azure SQL database. Then, an email summary is sent to the user with a link to the processing report. The link to the report must remain valid if the email is forwarded to another user.

A company is developing a solution that allows smart refrigerators to send temperature information to a central location. You have an existing Service Bus.
The solution must receive and store message until they can be processed. You create an Azure Service Bus Instance by providing a name, pricing tier, subscription, resource group, and location.
You need to complete the configuration.
Which Azure CLI or PowerShell command should you run?

1. A. Option A
2. B. Option B
3. C. Option C

Correct Answer: A
A service bus instance has already been created (Step 2 below). Next is step 3, Create a Service Bus queue. Note:
Steps:
Step 1: # Create a resource group resourceGroupName="myResourceGroup"
az group create --name $resourceGroupName --location eastus
Step 2: # Create a Service Bus messaging namespace with a unique name namespaceName=myNameSpace$RANDOM
az servicebus namespace create --resource-group $resourceGroupName --name $namespaceName --location eastus
Step 3: # Create a Service Bus queue
az servicebus queue create --resource-group $resourceGroupName --namespace-name $namespaceName
--name BasicQueue
Step 4: # Get the connection string for the namespace
connectionString=$(az servicebus namespace authorization-rule keys list --resource-group
$resourceGroupName --namespace-name $namespaceName --name RootManageSharedAccessKey --query primaryConnectionString --output tsv)
