Show Answer
Correct Answer: C

To identify unattached disks that can be deleted in an Azure subscription with 100 virtual machines, you should configure the Advisor recommendations from the Azure portal. Azure Advisor provides a consolidated view of how you can optimize your resources, including identifying idle and unattached disks, and offers recommendations for cost management and efficiency improvements.

if you go with 'A' you will have to do it for every vm's you remove/create (100+). instead if you have a report, you can action. thats why they gave report as a option

The answer is D although it's not accurately labeled because it's actually Cost Management + Billing > Cost Management > Optimize with recommendations. The description under this is "View Advisor recommendations to identify unused or underutilized resources. Take action to reduce waste."

Cern77 is correct, the correct answer is A. Under subscription and Storage account and Blob,

Musk

Option D does not exist, or is not called like that. I think option C is the right one, because the right option is named like that.

C seems more logical here to me

There is not an Optimizer tab under Cost Management blade? MS does have powershell scripts to find out unused disks managed or unmanaged. For this question, A is the only option for me.

JatinA

Home -> Cost Management + Billing -> Cost Management: Pay-As-You-Go - Overview -> Optimize with recommendations. This seems to resolve the issue of unused disks. So, the answer D seems to be correct. Answer A is also doable though it is a manual process to check every disk.

Answer is C

Corona_Virus
Apr 14, 2020

Answer is A You can find unused disks in the Azure Storage Explorer console. Once you drill down to the Blob containers under a storage account, you can see the lease state of the residing VHD (the lease state determines if the VHD is being used by any resource) and the VM to which it is leased out. If you find that the lease state and the VM fields are blank, it means that the VHD in question is unused. Reference: https://cloud.netapp.com/blog/reduce-azure-storage-costs

Looking at the possible choices, one is forced to pick between A, C, D. A: VM disks are not created in storage accounts.Even if you did, finding 100 disks is a herculean task. D: there is nothing like optimizer tab in cost management. Under overview, there is Optimize with Recommendations. Clicking this opens the Advisor recommendations blade and runs the report. So the answer is C: configure advisor recommendations.

Mor

Answer:A You can find unused disks in the Azure Storage Explorer console. Once you drill down to the Blob containers under a storage account, you can see the lease state of the residing VHD (the lease state determines if the VHD is being used by any resource) and the VM to which it is leased out. If you find that the lease state and the VM fields are blank, it means that the VHD in question is unused. The ManagedBy property stores the Id of the VM to which Managed Disk is attached to. If the ManagedBy property is $null then it means that the Managed Disk is not attached to a VM

I can not agree on this, I have an active vm, in the storage explorer, under blob, I can see the lease state and vm name are all blank. but the vm is running with the disk.

ah, that is not for VHD, it is for diag. there is no VHD in my storage explorer.

C. From the Azure portal, configure the Advisor recommendations. Azure Advisor - Identify unused VMs and receive recommendations about Azure reserved instance purchases. https://docs.microsoft.com/en-us/azure/cost-management-billing/cost-management-billing-overview

YPR
Jun 30, 2020

Option A is the correct answer. Question : You need to identify unattached disks that can be deleted Advisor provides recommendations where as unattached disks can be identified from the available disks under Microsoft Azure Storage Explorer. Both options can serve the purpose But option A makes more sense here. You can find unused disks in the Azure Storage Explorer console.Once you drill down to the Blob containers under a storage account, you can see the lease state of the residing VHD (the lease state determines if the VHD is being used by any resource) and the VM to which it is leased out. If you find that the lease state and the VM fields are blank, it means that the VHD in question is unused.

I have checked in my tenant and I can see the unattached disks in Storage explorer. Neither Azure Advisor recommendations nor Azure Cost Management provided details about unattached disks in VM.

Based on the options the answer is D A. From Microsoft Azure Storage Explorer, view the Account Management properties. [ From account management properties you can't see the underutilized] B. From Azure Cost Management, create a Cost Management report. [Cost management report is not an option] C. From the Azure portal, configure the Advisor recommendations. [No need to configure the advisor recommendations] D. From Azure Cost Management, open the Optimizer tab and create a report. [after elimination this is the answer]

Chipper

I am not even seeing an option for an "Optimizer" tab under Cost Management so D doesn't seem to be correct.

Azure Cost Management works with Azure Advisor to provide cost optimization recommendations. Azure Advisor helps you optimize and improve efficiency by identifying idle and underutilized resources. https://docs.microsoft.com/en-us/azure/cost-management-billing/costs/tutorial-acm-opt-recommendations So i feel answer is C

C it is, https://docs.microsoft.com/en-us/azure/advisor/advisor-overview Not D because: https://docs.microsoft.com/en-us/azure/cost-management-billing/costs/tutorial-acm-opt-recommendations

it does exist and the answer is d

Minimal1988
Feb 14, 2020

for 100 VMs the right way would be with powershell! but this answer is not available. So it can only be the Storage Explorer.

AnshMan

D is correct. "Recommendations show how you can optimize and improve efficiency by identifying idle and underutilized resources. " https://docs.microsoft.com/en-us/azure/cost-management-billing/cost-management-billing-overview

Happiman

It is a an underutilized resources, which means "VMs" not disks.

Folks both A and D are correct. Do not force yourself to choose just one answer.

A - as per docs.microsoft - Unmanaged disks are VHD files that are stored as page blobs in Azure storage account

Prash85
Jun 17, 2020

this seem to be a multiple choice question.. in that case its A & D

denkes
Jun 25, 2020

For me A seems the only possibility, given the provided Options A to D. According to Azure you'll do it this way: https://docs.microsoft.com/en-us/azure/virtual-machines/disks-find-unattached-portal?toc=/azure/virtual-machines/linux/toc.json&bc=/azure/virtual-machines/linux/breadcrumb/toc.json See there the screenshot, first screenshot column: Owner. In case, this field is empty, you have an unattached disk. You get this view also with the storage explorer, see here, number 2.): https://docs.microsoft.com/en-us/azure/virtual-machines/windows/disks-use-storage-explorer-managed-disks#upload-a-managed-disk-from-an-on-prem-vhd

denkes
Jun 25, 2020

"But account Management properties" does not make any sense, there you can't see VM owner. A is not an option. I go with D.

Answer likely C A is only to VHD, and not from Account Mgmt property, need look at CHD property one by one. D. I checked my EA and Azure Pass subscriptions, no Optimizer tab under Cost Mgmt + Billing. Maybe under Pas-as-you-go subscription only?

From the Azure Portal->disks(classic)->find the unattached disks. What's the confusion?

arseyam
Aug 9, 2020

The answer is D because the question is say how to identify the unattached disks not to implement a solution as C describes. I know the wording is confusing because this exam is old and Azure changed a lot.

Unmanaged disks: Find and delete unattached disks Unmanaged disks are VHD files that are stored as page blobs in Azure storage accounts. If you have unmanaged disks that aren't attached to a VM, no longer need the data on them, and would like to delete them, the following process explains how to do so from the Azure portal: -->Sign in to the Azure portal. -->Search for and select Disks (Classic).

jhxetc
Sep 4, 2020

It would make more sense for this question to be worded more like which option should you NOT pick. B,C and D all accomplish basically the same thing and I would consider all of them correct. A is the only answer that seems incomplete since just going to account management in the storage explorer will not by itself show you orphaned disks. The best answer of course would be to use the Disks blade, but that is not an option.

prince_norman_maximus
Sep 15, 2020

C because they'll always want you to use their latest and greatest tool; Azure Advisor. The Advisor tells you when disks are being unused. There are multiple correct ways to do this, but I believe C is the best answer.

Arnab_Sutar
Sep 21, 2020

Correct answer is C. Because Azure Optimization uses Azure Recommendation Services
