[All AZ-103 Questions]

SIMULATION -
Please wait while the virtual machine loads. Once loaded, you may proceed to the lab section. This may take a few minutes, and the wait time will not be deducted from your overall test time.
When the Next button is available, click it to access the lab section. In this section, you will perform a set of tasks in a live environment. While most functionality will be available to you as it would be in a live environment, some functionality (e.g, copy and paste, ability to navigate to external websites) will not be possible by design.
Scoring is based on the outcome of performing the tasks stated in the lab. In other words, it doesn't matter how you accomplish the task, if you successfully perform it, you will earn credit for that task.
Labs are not timed separately, and this exam may have more than one lab that you must complete. You can use as much time as you would like to complete each lab. But, you should manage your time appropriately to ensure that you are able to complete the lab(s) and all other sections of the exam in the time provided.
Please note that once you submit your work by clicking the Next button within a lab, you will NOT be able to return to the lab.
You may now click next to proceed to the lab.


You need to deploy an Azure virtual machine named VM1004a based on an Ubuntu Server image, and then configure VM1004a to meet the following requirements:
✑ The virtual machine must contain data disks that can store at least 15 TB of data.
✑ The data disks must be able to provide at least 2.000 IOPS.
✑ Storage costs must be minimized.
What should you do from the Azure portal?

Show Suggested Answer Hide Answer
Suggested Answer: See solution below.
Step 1: Open the Azure portal.
Step 2: On the left menu, select All resources. You can sort the resources by Type to easily find your images.
Step 3: Select the image you want to use from the list. The image Overview page opens.
Step 4: Select Create VM from the menu.
Step 5: Enter the virtual machine information.
Select VM1004a as the name for the first Virtual machine.
The user name and password entered here will be used to log in to the virtual machine. When complete, select OK. You can create the new VM in an existing resource group, or choose Create new to create a new resource group to store the VM.
Step 6: Select a size for the VM. To see more sizes, select View all or change the Supported disk type filter.
To meet the requirements select Standard SSD E70.
Standard SSD E70: Up to 16 TB, IOPS up to 4000, $1,228.80/month
Standard SSD Managed Disks, a low-cost SSD offering, are optimized for test and entry-level production workloads requiring consistent latency.
Step 7: Under Settings, make changes as necessary and select OK.
Step 8: On the summary page, you should see your image name listed as a Private image. Select Ok to start the virtual machine deployment.

This should be an S70 and not an E70 https://azure.microsoft.com/en-us/pricing/details/managed-disks/

BobRofl, an S70 disk provides "up to 2000 IOPS". The question ask for "at least 2000 IOPS". So, an E70 disk.

I agree with BobRofl. If a requirement is to have a car with at least 4 wheels, a car with max 4 wheels meets the requirements.

Nope. Wheels are not the same as IOPS, ahaha. "Up to 2000 IOPS" means that's the maximum IOPS you will ever get, but you will operate below that most of the time, be certain of that. If the requirement is AT LEAST, we can't settle for UP TO.

S70 is up to 2000 iops and this is max not "at least". In my opinion standard ssd E70 is the right answer

The data disks must be able to provide at least 2.000 IOPS - means performance must not go below 2000 IOPS. If you choose S70 it will always be maxed out and will not be healthy in the long run so may cause frequent replacement (in the end too costly) Choosing E70 will ensure that it can operate at 2000 and higher thus ensuring integrity during heavy operations that are 2000 and above IOPS.

Does anyone here know if the simulations on the test have the handy list of drives and their performance like when you click on Add Disk in the production version of Azure?

reviewed again. S70 is cheaper thus the more appropriate choice. https://azure.microsoft.com/en-us/pricing/details/managed-disks/ E70 16 TiB $1,228.80 Up to 4,000 Up to 600 MB/second S70 16 TiB $491.52 Up to 2,000 Up to 500 MB/second

Correct VM size is S70 but when I wanted to do practice, could not see/select S70 for ubunti image. Is this can be limitation of subscription ?

S70 is the data disk size, not the VM size. We need to choose any VM size that supports more than 2000 IOPS. Than, we need to select the S70 disk size, wich is Standard HDD, for the purpose of minimizing costs.

DIsk has to be AT LEAST 2000 IOPS. By saying at least, the questions is expecting the IOPS to be higher than 2000 so E70 is the right answer for this question

agree with you macco455 because E70 provides upto 4000 IOPS whereas S70 only 2000. So the option would be E70.

'the data disks' … shouldn't we create the VM first with a small disk for the OS, and then add a data disk after creation as per requirements and as per best practise?

Also with these questions don't forget the Terabyte vs Tebibyte component - Azure Portal states sizes in TiB, the question is stating in TB - there is a slight difference. In this case E70 is still correct as it provides 16TiB which is 17.59TB, and up to 4000 IOPS.
