East US
contoso102
Storage account

Question 1:
You can create a Premium file share in ___ ?
# Answer: contoso104 only
Premium file shares in Azure use Azure Files Premium performance tier, which is available only with FileStorage accounts.
Per Microsoft Azure documentation:
"To create a Premium file share, you must use a storage account of kind FileStorage with performance tier set to Premium." contoso104 is the only account of type FileStorage, so only it supports premium file shares.
Question 2:
You can use the Archive access tier in ___ ?
# Answer: contoso101, contoso102, and contoso103 only
The Archive access tier is available only for Blob storage objects stored in:
General-purpose v2 (StorageV2) accounts, or
BlobStorage accounts.
It is not supported in:
FileStorage accounts (used for file shares).
Thus:
contoso101 (StorageV2) # Supports Archive tier
contoso102 (Storage) # Legacy (no Archive support)
contoso103 (BlobStorage) # Supports Archive tier
contoso104 (FileStorage) # File shares only
Correction: Storage (V1) supports only Hot and Cool access tiers, not Archive.
So, the correct accounts that support the Archive tier are:
# contoso101 and contoso103 only
# Final Verified Answers:
Question
Correct Answer
You can create a premium file share in
contoso104 only
You can use the Archive access tier in
contoso101 and contoso103 only
Microsoft Azure Administrator Documentation Extracts:
"Premium file shares are available only in FileStorage accounts and provide low-latency, high-performance storage for Azure Files."
"The Archive tier is supported for Blob Storage and General-purpose v2 accounts only." (Source: Microsoft Learn - "Azure storage account overview" & "Access tiers for Azure Blob Storage")

Explanation:

When a virtual machine (VM) in Azure is scheduled for platform maintenance, it can either be planned maintenance (with notification) or unplanned maintenance (without notice). During planned maintenance, administrators have the option to move the VM to a different host proactively to minimize downtime.
According to Microsoft Azure documentation ("Maintenance and updates for Azure virtual machines"), the correct action is to use the "Redeploy" or "Move to another host" feature, not a "One-time update." The
"Redeploy" operation deallocates the VM and migrates it to a new node within Azure's infrastructure, resolving underlying host issues while preserving OS and data disks.
The "Updates blade" in the Azure portal does not contain a "One-time update" option to move a VM off a host. That term is used in the context of patching or guest OS updates, not host maintenance.
Therefore, the proposed solution does not meet the goal of moving the VM to another host immediately. The correct action would be to redeploy the VM using the Azure portal or Invoke-AzVMRedeploy PowerShell cmdlet.

To create a load balancing rule that will load balance HTTPS traffic between VM1 and VM2, you need to create two additional load balance resources: a frontend IP address and a health probe.
A frontend IP address is the IP address that the clients use to access the load balancer. It can be either public or private, depending on the type of load balancer. A frontend IP address is required for any load balancing rule1.
A health probe is used to monitor the health and availability of the backend instances. It can be either TCP, HTTP, or HTTPS, depending on the protocol of the load balancing rule. A health probe is required for any load balancing rule1.
A backend pool is a group of backend instances that receive the traffic from the load balancer. You already have a backend pool that contains VM1 and VM2, so you don't need to create another one.
An inbound NAT rule is used to forward traffic from a specific port on the frontend IP address to a specific port on a backend instance. It's not required for a load balancing rule, but it can be used to access individual instances for troubleshooting or maintenance purposes1.
A virtual network is a logical isolation of Azure resources within a region. It's not a load balance resource, but it's required for creating an internal load balancer or connecting virtual machines to a load balancer2.

To enable communication between virtual machines (VMs) located in different virtual networks (VNets) in Azure, the most efficient and recommended approach-according to Microsoft Azure Administrator documentation-is to use VNet peering.
1. Background and Scenario Analysis
From the case study:
VM1 and VM4 are located in different VNets (VNET1 and VNET3).
The requirement is to ensure that VM1 can communicate with VM4.
The solution must minimize administrative effort and cost.
2. Microsoft Documentation Insight: VNet Peering
According to Microsoft Learn: "Virtual network peering":
"Virtual network peering seamlessly connects two Azure virtual networks. The virtual networks appear as one for connectivity purposes. Traffic between peered virtual networks uses private IP addresses, as if they were part of the same network, and the traffic stays entirely on the Microsoft backbone network." Key characteristics of VNet peering:
Enables private IP connectivity between resources across peered VNets.
No need to deploy or maintain gateways (unlike VPN gateways).
Provides low latency and high bandwidth.
Supports transitive routing through additional configurations.
Minimal administrative overhead - peering can be created with just a few clicks or PowerShell/CLI commands.
3. Why the Other Options Are Incorrect
A). Create a user-defined route (UDR) from VNET1 to VNET3.
# A UDR alone cannot enable connectivity between VNets unless a gateway or peering already exists.
Without a connection path, a route has no effect.
B). Assign VM4 an IP address of 10.0.1.5/24.
# This would attempt to place VM4 in the same subnet as VM1, but cross-VNet subnet IP assignment is not possible in Azure. Each VNet has its own isolated address space.
D). Create an NSG and associate it with VM1 and VM4.
# Network Security Groups control traffic filtering within or between existing network connections. They do not create connectivity between isolated VNets.
4. Why Peering Is the Correct and Simplest Solution
Establishing VNet peering between VNET1 and VNET3 will:
Instantly enable bidirectional private IP communication between VM1 and VM4.
Minimize administrative effort (no gateways, routing tables, or IP reconfiguration).
Maintain security and performance through Microsoft's internal backbone.
Avoid additional costs compared to deploying VPN gateways.
5. Implementation Summary
Steps to configure:
In the Azure Portal, go to VNET1 # Peerings # Add.
Choose VNET3 as the peer virtual network.
Enable Allow virtual network access in both directions.
Once completed, both VMs (VM1 and VM4) will communicate using their private IPs.
Final Verified Answer: # C. Establish peering between VNET1 and VNET3
