Actual exam question from Microsoft's DP-203

Question #: 31
Topic #: 3

HOTSPOT -
You have an Azure subscription.
You need to deploy an Azure Data Lake Storage Gen2 Premium account. The solution must meet the following requirements:
* Blobs that are older than 365 days must be deleted.
* Administrative effort must be minimized.
* Costs must be minimized.
What should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

Show Suggested Answer

Suggested Answer:

Box 1: The Archive access tier -
Archive tier - An offline tier optimized for storing data that is rarely accessed, and that has flexible latency requirements, on the order of hours. Data in the Archive tier should be stored for a minimum of 180 days.
Box 2: Azure Storage lifecycle management
With the lifecycle management policy, you can:
* Delete current versions of a blob, previous versions of a blob, or blob snapshots at the end of their lifecycles.
Transition blobs from cool to hot immediately when they're accessed, to optimize for performance.
Transition current versions of a blob, previous versions of a blob, or blob snapshots to a cooler storage tier if these objects haven't been accessed or modified for a period of time, to optimize for cost. In this scenario, the lifecycle management policy can move objects from hot to cool, from hot to archive, or from cool to archive.
Etc.

If u choose premium storage account, there is no possibility to choose tiers (hot, cool, archive), its always hot, sa LRS and lifecycle storage mngt

Agree no mention for tiering in the quetion so LRS is the best option to minimize the cost

its not the same as hot; see this microsoft article: https://azure.microsoft.com/nl-nl/blog/azure-premium-block-blob-storage-is-now-generally-available/ "'Premium Blob Storage is a new performance tier in Azure Blob Storage for block blobs and append blobs, complimenting the existing Hot, Cool, and Archive access tiers.

The statement doesn't mention requirement for a tiercing storage archive nor cool nor hot before deletion. Then I think it is LRS and lifecycle storage mngt

Azure Data Lake Storage Gen2 Premium accounts are optimized for high-performance workloads, but they do not currently support archive access tiers. Archive tiers are available in standard storage accounts for Azure Data Lake Storage Gen2, which are designed for cost-effective long-term storage of infrequently accessed data.

1. Premium does not support other than Hot. Azure does recommend LRS for lower costs. 2. Lifecycle can be set in Premium and can manage the removal. Notes: - Soft delete is about recovery, not [programmed] removal. - I just tested what I wrote. - ChatGPT can be challenged if you feel it provided a wrong answer. And it does.

Chatgpt : To minimize costs, select **The Archive access tier** since it is optimized for data that is rarely accessed and offers the lowest storage cost. For the deletion of blobs older than 365 days, you would use **Azure Storage lifecycle management** to automate the deletion process, reducing administrative effort.

For your Azure Data Lake Storage Gen2 Premium account, considering the requirements: To minimize costs: Locally-redundant storage (LRS). This is cost-effective and provides high durability within a single region. To delete blobs older than 365 days: Azure Automation runbooks. Since Azure Storage lifecycle management isn't applicable to Premium tier, automation runbooks can be used to programmatically delete older blobs, minimizing administrative effort.

LRS and data lifecycle. Even tho you can't switch data from tier-to-tier, you can still apply a rule to delete the BLOB once it reaches 365 days.

According to https://learn.microsoft.com/en-us/azure/storage/blobs/access-tiers-overview?tabs=azure-portal "Data stored in a premium block blob storage account cannot be tiered to hot, cool, cold or archive by using Set Blob Tier or using Azure Blob Storage lifecycle management." So answers are LRS and Soft delete https://learn.microsoft.com/en-us/azure/storage/blobs/soft-delete-blob-overview https://learn.microsoft.com/en-us/azure/storage/blobs/soft-delete-container-enable?tabs=azure-portal

Azure Blob Storage Lifecycle Management allows you to create rules to automatically delete blobs based on their age, reducing administrative effort and minimizing costs. This makes it a better option for meeting the requirements specified in your scenario. Soft delete is an option for protecting against accidental deletion of blobs, but it is not the best option for automatically deleting blobs that are older than 365 days. Soft delete works by retaining deleted blobs for a specified period of time, allowing you to recover them if needed. However, it does not automatically delete blobs based on their age.

áccording to microsoft: '"Premium Blob Storage is a new performance tier in Azure Blob Storage for block blobs and append blobs, complimenting the existing Hot, Cool, and Archive access tiers. "" https://azure.microsoft.com/nl-nl/blog/azure-premium-block-blob-storage-is-now-generally-available/ so the only two other options left are LRS and ZRS; LRS is cheaper; so it must be this one;

also in the documentation all the three tiers are greyed out for premium https://learn.microsoft.com/en-us/azure/storage/blobs/storage-feature-support-in-storage-accounts#premium-block-blob-accounts so you cannot possibly choose this as an answer;

Box1: Locally-redundant storage (LRS) In the question, it specifically states that "You need to deploy an Azure Data Lake Storage Gen2 Premium account", and Azure Data Lake Storage Gen2 premium tier is neither an Archive access tier nor a Cool Access tier, and so those two options are out. Locally-redundant storage (LRS) is less expensive than Zone-redundant storage (ZRS), so we choose LRS. https://learn.microsoft.com/en-us/azure/storage/blobs/premium-tier-for-data-lake-storage Box2: Azure Storage Lifecycle management Well explained in the answer already.
