You are developing an Azure Function App by using Visual Studio. The app will process orders input by an Azure Web App. The web app places the order information into Azure Queue Storage.
You need to review the Azure Function App code shown below.
NOTE: Each correct selection is worth one point.
正解:
解説:
Explanation
Box 1: No
ExpirationTime - The time that the message expires.
InsertionTime - The time that the message was added to the queue.
Box 2: Yes
maxDequeueCount - The number of times to try processing a message before moving it to the poison queue.
Default value is 5.
Box 3: Yes
When there are multiple queue messages waiting, the queue trigger retrieves a batch of messages and invokes function instances concurrently to process them. By default, the batch size is 16. When the number being processed gets down to 8, the runtime gets another batch and starts processing those messages. So the maximum number of concurrent messages being processed per function on one virtual machine (VM) is 24.
Box 4: Yes

Drag and Drop Question
You have an Azure subscription.
You must create a file share with a quota of 2,048 GB. You create the following variables:
In which order should you arrange the Azure CLI commands to develop the solution? To answer, move all the commands from the list of commands to the answer area and arrange them in the correct order.
正解:
解説:
Explanation:
Step 1:
Create a resource group
A resource group is a logical container in which Azure resources are deployed and managed. If you don't already have an Azure resource group, you can use the az group create command to create one.
The following example creates a resource group named myResourceGroup in the East US location:
az group create --name myResourceGroup --location eastus
Step 2:
Create a storage account
The following example creates a storage account named mystorageaccount<random number> by using the az storage account create command, and then puts the name of that storage account in the $STORAGEACCT variable.
STORAGEACCT=$(az storage account create \
--resource-group "myResourceGroup" \
--name "mystorageacct$RANDOM" \
--location eastus \
--sku Standard_LRS \
--query "name" | tr -d '"')
Step 3:
Get the storage account key
Storage account keys control access to resources in a storage account. The keys are automatically created when you create a storage account. You can get the storage account keys for your storage account by using the az storage account keys list command:
STORAGEKEY=$(az storage account keys list \
--resource-group "myResourceGroup" \
--account-name $STORAGEACCT \
--query "[0].value" | tr -d '"')
Step 4:
Now, you can create your Azure file share. Create file shares by using the az storage share create command. This example creates an Azure file share named myshare:
az storage share create \
--account-name $STORAGEACCT \
--account-key $STORAGEKEY \
--name "myshare"
