Metadata.Add example:
// Add metadata to the dictionary by calling the Add method
metadata.Add("docType", "textDocuments");
SetMetadataAsync example:
// Set the blob's metadata.
await blob.SetMetadataAsync(metadata);
// Set the blob's properties.
await blob.SetPropertiesAsync();

Explanation:
Box 1: Custom handler
Custom handlers can be used to create functions in any language or runtime by running an HTTP server process, for example Go or Rust.
Box 2: Trigger
Functions are invoked by a trigger and can have exactly one. In addition to invoking the function, certain triggers also serve as bindings. You may also define multiple bindings in addition to the trigger. Bindings provide a declarative way to connect data to your code.

Explanation:
Box 1: role-based access control (RBAC)
Azure Storage supports authentication and authorization with Azure AD for the Blob and Queue services via Azure role-based access control (Azure RBAC).
Scenario: File access must restrict access by IP, protocol, and Azure AD rights.
Box 2: change feed
The purpose of the change feed is to provide transaction logs of all the changes that occur to the blobs and the blob metadata in your storage account.
The file updates must be read-only, stored in the order in which they occurred, include only create, update, delete, and copy operations, and be retained for compliance reasons.

Explanation:
Step 1: Create a Log Analytics workspace.
First create the workspace.
Step 2: Add a VMInsights solution.
Before a Log Analytics workspace can be used with VM insights, it must have the VMInsights solution installed.
Step 3: Install agents on the VM and VM scale set to be monitored.
Prior to onboarding agents, you must create and configure a workspace. Install or update the Application Insights Agent as an extension for Azure virtual machines and VM scalet sets.
Step 4: Create an Application Insights resource
Sign in to the Azure portal, and create an Application Insights resource.
Once a workspace-based Application Insights resource has been created, configuring monitoring is relatively straightforward.

You are developing applications for a company. You plan to host the applications on Azure App Services.
The company has the following requirements:
* Every five minutes verify that the websites are responsive.
* Verify that the websites respond within a specified time threshold. Dependent requests such as images and JavaScript files must load properly.
* Generate alerts if a website is experiencing issues.
* If a website fails to load, the system must attempt to reload the site three more times.
You need to implement this process with the least amount of effort.

You develop several Azure Grid to include hundreds of event types, such as billing, inventory, and shipping updates.
Events must be sent to a single endpoint for the Azure Functions app to process. The events must be filtered by event type before processing. You must have authorization and authentication control to partition your tenants to receive the event data.
You need to configure Azure Event Grid.
Which configuration should you use? To answer, select the appropriate values in the answer area.

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

You plan to deploy a new application to a Linux virtual machine (VM) that is hosted in Azure.

Explanation:
Box 1: keyvault
Create an Azure Key Vault with az keyvault create and enable the Key Vault for use with disk encryption.
Specify a unique Key Vault name for keyvault_name as follows:
keyvault_name=myvaultname$RANDOM
az keyvault create \
--name $keyvault_name \
--resource-group $resourcegroup \
--location eastus \
--enabled-for-disk-encryption True
Box 2: keyvault key
The Azure platform needs to be granted access to request the cryptographic keys when the VM boots to decrypt the virtual disks. Create a cryptographic key in your Key Vault with az keyvault key create. The following example creates a key named myKey:
az keyvault key create \
--vault-name $keyvault_name \
--name myKey \
--protection software
Box 3: vm
Create a VM with az vm create. Only certain marketplace images support disk encryption. The following example creates a VM named myVM using an Ubuntu 16.04 LTS image:
az vm create \
--resource-group $resourcegroup \
--name myVM \
--image Canonical:UbuntuServer:16.04-LTS:latest \
--admin-username azureuser \
--generate-ssh-keys \
Box 4: vm encryption
Encrypt your VM with az vm encryption enable:
az vm encryption enable \
--resource-group $resourcegroup \
--name myVM \
--disk-encryption-keyvault $keyvault_name \
--key-encryption-key myKey \
--volume-type all
Note: seems to an error in the question. Should have enable instead of create.
Box 5: all
Encrypt both data and operating system.
