Question 383

How many copies of data are maintained by an Azure Storage account that uses geo-redundant storage (GRS)?

    Correct Answer: C

    Azure Storage accounts that use geo-redundant storage (GRS) maintain six copies of data. This involves creating three synchronous copies in a single physical location in the primary region using locally redundant storage (LRS). Additionally, it creates three asynchronous copies in a secondary region that is geographically distant from the primary region. This setup ensures high availability and disaster recovery.

wyderroOption: C

Wrong, C is correct: https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy#geo-redundant-storage "Geo-redundant storage (GRS) copies your data synchronously three times within a single physical location in the primary region using LRS. It then copies your data asynchronously to a single physical location in a secondary region that is hundreds of miles away from the primary region."

slayerdrum

I agree. There are 6 instances of the data

Fortunately, right answers are found in this discussion with reference to appropriate Microsoft documentation. Thanks you vauable Contributors.

JohannesV

Yes, thanks to all and also, I knew the answer was C from studying the material.

My experience is that examtopics.com is one of the best, if not the best, site for exam preparations. Contributor access is well worth the money. Do not buy so called 'legit and up to date' practice exams from other sites. I fell for that trap a few times and they all contained errors and/or were ripoffs.

SRIRAMTRAININGSGOption: C

https://learn.microsoft.com/en-us/azure/storage/files/files-redundancy states clearly that for GRS: Six copies total, including three in the primary region and three in the secondary region

dayoteeOption: A

Here is the reply I got from Copilot: "In summary, GRS maintains three synchronous copies of your data in the primary region and an additional asynchronous copy in a secondary region, ensuring robust data redundancy and resilience". That means the answer is 3 copies (A) as you only maintain 3 while others are replicas.

why dont they verify the answers before publishing at least for paid subscribers? it's a lot wrong answers and we have to deep dive to the comments..

Andrew_SOption: C

6 of course. Three in each region. How can we crowdsource a better set of updated answers?

e3ddcebOption: C

C. 6 Geo-redundant storage (GRS) in Azure Storage maintains six copies of data. Here's how it works: Three copies of the data are kept in the primary region. These copies are distributed across different fault domains and update domains to ensure high availability and durability. Another three copies are kept in a secondary region far away from the primary region. This is done for disaster recovery purposes. If the primary region becomes unavailable due to a major incident or disaster, Azure Storage will failover to the secondary region. So in total, GRS maintains six copies of data.

rajsOption: B

Many people have voted ANSWER C but according to the CHATGPT answer is B

siculoctOption: C

Is C - 6 copies

b76e714Option: C

3 copies in LRS * 2 = GRS

LaReisOption: A

O Armazenamento do Azure oferece duas opções para copiar seus dados para uma região secundária: O armazenamento com redundância geográfica (GRS) copia seus dados de forma síncrona TRÊS vezes em um único local físico na região primária usando o LRS. Fonte: https://learn.microsoft.com/pt-br/azure/storage/common/storage-redundancy

DallasMOption: C

6 copies. ZRS in primary region (3 copies across 3 availability zones) and LRS in secondary region (3 copies in same availability zone)

DallasM

Oops sorry LRS in both. For some reason was thinking GZRS.

Vitos25Option: C

Answer should be 6 https://mycloudit.com/blog/5-must-know-facts-about-microsoft-azure#:~:text=Azure%20Storage%20will%20maintain%20at,storage%20(RA%2DGRS).

x_Examinator_xOption: C

it's 6x

DimsumDestroyerOption: C

6 data copies. GRS is replicating in two regions, and in each region a physical location which replicates 3 times each. 2x3 = 6.
