Exam AZ-305 topic 2 question 4 discussion

The solution is CORRECT, because BlockBlobStorage provide a very low latency(x40) (Read and Write) and Throughput (x5) BECAUSE: One big file is splitted in "blobs" that are processed in parallel (for read and write) https://azure.microsoft.com/en-us/blog/premium-block-blob-storage-a-new-level-of-performance/

Correct answer, but given reasoning for Archive Tier is wrong. You achieve the immutability requirement through a Time-Based Retention Policy at the container-level. That will prevent write and delete operations for all blobs in the container for a given period (in this case, 1 year).

Another question designed to confuse you / obfuscate what Azure services actually offer. The storage account types are not listed correctly - why design questions this way, what is the purpose, other than to trip you up? Refer to the table here for the type of storage accounts supported in Azure: https://learn.microsoft.com/en-us/azure/storage/common/storage-account-overview#types-of-storage-accounts

CORRECT

The given answer is correct. BlockBlobStorage is the optimal storage account type because it is designed to handle large-scale, high-throughput operations and supports features that prevent data modification. Blob storage service is the right choice for storing large amounts of unstructured data and minimizing latency.

Given answer is correct

correct ans: Azure StorageV2 with Premium performance(immutable storage: no data modification for 1 year) blob storage

Got this on Aug 5th, 2023.

But if one of the requirements is to prevent the modification of data for one year, I think the correct choice would be a StorageV2 with standard performance because blob immutability is only available in General Purpose V2 storage account

Based on your requirements, the following options should be chosen: 1. Storage account type: BlockBlobStorage. This storage account type offers high-performance block blobs and append blobs. It provides the highest throughput for object storage in Azure, which will help maximize data throughput. Block blobs are ideal for storing text and binary data, such as documents and media files. 2. Storage service: Blob. Blob storage is optimized for storing massive amounts of unstructured data, and it can handle frequently accessed data very well. Also, Azure Blob Storage supports object-level immutability policies, which can prevent the modification of data for a certain period, satisfying your requirement to prevent data modification for one year.

1. BlockBlobStorage 2. Blob https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-block-blob-premium Premium block blob storage accounts make data available via high-performance hardware. Data is stored on solid-state drives (SSDs) which are optimized for low latency. SSDs provide higher throughput compared to traditional hard drives. File transfer is much faster because data is stored on instantly accessible memory chips. All parts of a drive accessible at once. By contrast, the performance of a hard disk drive (HDD) depends on the proximity of data to the read/write heads.

Solution is Correct. You create a Storage Account (not StorageV2 something), then you chose the performance: - Standard: type will be General Purpose v2 - Premium: 3 choices of type - BlockBlob - FilesShares - PageBlobs So here we should choice premium block blob type, with blob https://learn.microsoft.com/en-us/azure/storage/common/storage-account-overview?toc=%2Fazure%2Fstorage%2Fblobs%2Ftoc.json

Was there such a thing called "StorageV2 with Premium performance"? Is this question sort of outdated?

When you try to create a new storage account, there are two options : Standard and Premium. When you click on Premium, there are three options - Block Blobs, Page Blobs and File Shares. We need Block Blobs to satisfy the first and last requirements. For the second requirement we need Blob for the retention ability.

BlockBlobStorage Blob Correct answer Thanks to all who have mentioned the exam dates

I am a bit confused because storageV2 premium includes blockblob, isnt it?
