SIMULATION -
Click to expand each objective. To connect to the Azure portal, type https://portal.azure.com in the browser address bar.






When you are finished performing all the tasks, click the "˜Next' button.
Note that you cannot return to the lab once you click the "˜Next' button. Scoring occur in the background while you complete the rest of the exam.

Overview -
The following section of the exam is a lab. 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.

To start the lab -
You may start the lab by clicking the Next button.
You plan to migrate a large amount of corporate data to Azure Storage and to back up files stored on old hardware to Azure Storage.
You need to create a storage account named corpdata8548984n1, in the corpdatalod8548984 resource group. The solution must meet the following requirements:
- corpdata8548984n1 must be able to host the virtual disk files for Azure virtual machines
- The cost of accessing the files must be minimized
- Replication costs must be minimized
What should you do from the Azure portal?

Show Suggested Answer Hide Answer
Suggested Answer: See solution below.
Step 1: In the Azure portal, click All services. In the list of resources, type Storage Accounts. As you begin typing, the list filters based on your input. Select
Storage Accounts.
Step 2: On the Storage Accounts window that appears, choose Add.
Step 3: Select the subscription in which to create the storage account.
Step 4: Under the Resource group field, select corpdatalod8548984.

Step 5: Enter a name for your storage account: corpdata8548984n1
Step 6: For Account kind select: General-purpose v2 accounts (recommended for most scenarios)
General-purpose v2 accounts is recommended for most scenarios. General-purpose v2 accounts deliver the lowest per-gigabyte capacity prices for Azure
Storage, as well as industry-competitive transaction prices.
Step 7: For replication select: Read-access geo-redundant storage (RA-GRS)
Read-access geo-redundant storage (RA-GRS) maximizes availability for your storage account. RA-GRS provides read-only access to the data in the secondary location, in addition to geo-replication across two regions.

The requirement is "Replication cost should be minimized" It means that data redundancy should be set to LRS not RA-GRS. RA-GRS cost is the highest.

Set up Storage v2 Premium with LRS enabled for best cost. Yes Premium is more than standard, but the question states that it will need to house the VHD files for virtual machines therefore it will be access frequently and Premium is better suited for VHDs than standard is due to having SSDs vs standard HDD.

1. Cost of accessing must be minimized - This rules out cool tiers (hot tiers are cheaper when it comes to access the data) 2. Replication cost must be minized - This only allows for LRS which is the cheapest - This also means "Standard" performance over "Premium" as this doesn't support other replication scenarios then LRS 3. Must be able to host Azure VM disk files - This calls for page blob support - Rules out "BlobStorage" as this only supports block and append blobs Result: Performance = Standard Account kind = StorageV2 (Microsoft recommends V2 over V1 for new accounts) Replication = LRS Access tier = Hot

GPv2 LRS is clear (BlobStorage is not applicable because VM disks are usually Page blobs) But if I want to eliminate file access costs I can use a Premium Storage Account.. that would be a technically correct, but stupid move..

"corpdata8548984n1 must be able to host the virtual disk files for Azure virtual machines" Shouldn't we create a file share in storage account ?

You don't speak about "Performance" to "Standard". - Storage account : corpdatalod7523690n2 - Performance : Standard (The cost of accessing the files must be minimized)) - Account kind : StorageV2 (Must be able to host the virtual disk files for Azure virtual machines) - Replication : LRS (Replication costs must be minimized) - Access tier : Hot (The cost of accessing the files must be minimized)

Agree it should be LRS - not RA-GRS. No mention of requirements for cross region replication and this will drive up costs also.

create a storage account with GPv2 (allows blob storage), LRS (to save costs), hot tier.That's it.

it is for backup , so hot is not required .. cool would be better.

you are wrong. IT SAYS COST FOR ACCESSING FILES MUST BE MINIMIZED. SO HOT IS CORRECT

The ask is simple and straight forward 1. Replication cost should be minimized - For this we should choose LRS and not RA-GRS 2. he cost of accessing the files must be minimized - This is possible when the access tier is set to Cool Tier.

For your 2nd answer i think it should also be hot not cool as hot tiers are cheaper to "access" than cool ones. https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-storage-tiers?tabs=azure-portal Data access costs: Data access charges increase as the tier gets cooler. For data in the cool and archive access tier, you're charged a per-gigabyte data access charge for reads.

The question asks : the cost of accessing should be minimized in this case the tier would be hot. Cool would be the case when it is asked that "Cost of storing the data should be minimized"

Wouldn’t storage account general-purpose v1 be the cheapest option in terms of the replication charges and access (cheaper storage transactions)

Technically yes, but MS is trying to depreciate it. So not a valid strategy.

I believe access tier should be selected as cool to reduce cost as access to backup files will be categorized with infrequent access.

requirement: The cost of accessing the files must be minimized accessing "cool access tier" is more expensive therefore i suppose correct answer is HOT access tier storage Data in the cool access tier can tolerate slightly lower availability, but still requires high durability, retrieval latency, and throughput characteristics similar to hot data. For cool data, a slightly lower availability service-level agreement (SLA) and higher access costs compared to hot data are acceptable trade-offs for lower storage costs. from: https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-storage-tiers
