Actual exam question from Microsoft's AZ-140
Question #: 13
Topic #: 4
[All AZ-140 Questions]

HOTSPOT -
You have an Azure Virtual Desktop host pool named Pool1 and an Azure Storage account named storage1. Pool1 and storage1 are in the same Azure region.
The current network utilization of the session hosts during peak hours is 95%.
You plan to use FSLogix profile containers stored in storage1 for users that connect to Pool1.
You need to configure the session hosts and storage1 to minimize network latency when loading and updating profiles.
What should you do? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Adding network adapters to a VM does not increase tha available bandwidth. So you need to increase the VMs size. https://docs.microsoft.com/en-us/azure/virtual-network/virtual-machine-network-throughput#expected-network-throughput

I believe the given answers are correct. The question states that the Network Utilization on the Session Hosts is 95% not the bandwidth utilization of the network. You can add additional adapters to increase the available Network Capacity of the individual Session Hosts. Having the private endpoint for the Storage account also reduces the latency as the session hosts are now accessing the storage via a "Localized" network path.

I agree. Referred webpage said: "The network bandwidth allocated to each virtual machine is metered on egress (outbound) traffic from the virtual machine. All network traffic leaving the virtual machine is counted toward the allocated limit, regardless of destination." So additional network card does not help. (Write accelerator only applies for managed disks... out of scope) Increase virtual machine size give more network throughput. e.g.: https://docs.microsoft.com/en-us/azure/virtual-machines/dv3-dsv3-series

agreed. check out the table on any of the series-specific comparison pages and you'll see that even for VMs where the max number of NICs is the same, the expected bandwidth increases with the size of the VM. https://learn.microsoft.com/en-us/azure/virtual-machines/dv3-dsv3-series

Add additional network adapters: Increasing the number of network adapters on your session hosts can distribute network traffic more efficiently and reduce contention, potentially improving network latency.

For storage1: Configure a private endpoint Reason: Configuring a private endpoint will enable secure and fast access to the Azure Storage account within the virtual network (VNet). This setup minimizes network latency by routing traffic directly through the Azure backbone instead of traversing the public internet. It also provides enhanced security by restricting access to the storage account through the VNet. For the session hosts: Add additional network adapters Reason: By adding additional network adapters, you can increase network throughput and improve performance. This can help distribute the network load, reduce bottlenecks, and improve the speed at which FSLogix profiles are loaded and updated, especially during peak usage hours. This approach ensures better bandwidth management for the session hosts.

Cmon guys, you can't breach the bandwidth limit set per VM size... you HAVE to increase VM size.

I think the answer is correct. If you create an additional NIC and a Private Endpoint all the traffic regarding the storage will flow only through that NIC, so the latency for the storage will be reduced. https://learn.microsoft.com/en-us/azure/storage/common/storage-private-endpoints#:~:text=A%20private%20endpoint%20is,a%20secure%20private%20link.

Larger virtual machines are allocated relatively more bandwidth than smaller virtual machines. Azure virtual machines must have one, but may have several, network interfaces attached to them. Bandwidth allocated to a virtual machine is the sum of all outbound traffic across all network interfaces attached to a virtual machine. In other words, the allocated bandwidth is per virtual machine, regardless of how many network interfaces are attached to the virtual machine - Based on this Increase the VM size is the best choice

You've interpreted that wrong. Allocated bandwidth = Bandwidth Given to a Virtual Machine Sum of all outbound traffic across all network interfaces = Nic1 + Nic2 + Nic3 So you're right in one sense; it doesn't matter how many NICs you add that doesn't change the amount of traffic generated by/allocated to the VM. However, if your VM is producing more traffic than can be pushed out by the available NICs; you need more NICs. Adding additional NICs will allow more traffic to flow in/out, and as a result your Bandwidth Allocation/Utilization will increase on the network, but the %network utilization on the VM will decrease as there is larger network capacity available to the VM.

Where did you find that information. Is not logical at all. If you have more than one NIC on a VM or physical machine you increase the amount of data that flows in and out, and you actually can prioritize the traffic to one NIC if you want too. If you actually have Microsoft documentation that says that, please go ahead and prove I'm wrong.

Private endpoint and network adaptors. The following are general best practices for FSLogix profile containers. For optimal performance, the storage solution and the FSLogix profile container should be in the same data-center location. Exclude the VHD(X) files for profile containers from antivirus scanning, to avoid performance bottlenecks. We recommend using a separate profile container per host pool, while having two active sessions. Private link for Azure storage could be used to enable a more secure data access as well as to improve the network latency from your session hosts to your storage account. This is also beneficial in hybrid scenarios with ExpressRoute connectivity. https://docs.microsoft.com/en-us/azure/architecture/example-scenario/wvd/windows-virtual-desktop-fslogix#best-practices

Quick question, what is "configure private endpoint"? in the storage ? lol

When you create the storage account to be used for the file share that the FSlogix profile will be stored in you can choose to create an endpoint; typically you can do public or private endpoints; the public would have a public IP and private would have an IP on a subnet within your vNET. What you typically do is add a private endpoint to the SA and then pair a 2nd nic that is associated with the AVD session host that is pinned to the same subnet that the private endpoint lives on. This way when traffic is fetched for the profiles the data goes over its own subnet. Something else to consider, an additional nic beyond the defacto nic assigned to an AVD host is a 10GB nic vs the standard 1G nic. This solution drastically increases the bandwidth performance of the storage account, the profiles, and allows the defacto nic to be used for RDP sessions via the AVD storefront. This same solution would be used for other applications if you can think creatively. ;-)

Configure a private endpoint: Creating a private endpoint for the Azure Storage account ensures that the data transfer between your session hosts and the storage account remains within the Azure network, reducing latency and improving security.
