HOTSPOT -
You plan to create an Azure Storage account in the Azure region of East US 2.
You need to create a storage account that meets the following requirements:
✑ Replicates synchronously.
✑ Remains available if a single data center in the region fails.
How should you configure the storage account? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Box 1: Zone-redundant storage (ZRS)
Zone-redundant storage (ZRS) replicates your data synchronously across three storage clusters in a single region.
LRS would not remain available if a data center in the region fails
GRS and RA GRS use asynchronous replication.
Box 2: StorageV2 (general purpose V2)
ZRS only support GPv2.
Reference:
https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy-zrs
The Answer should be Zone not GRS.
1st answer is ZRS 2nd answer is StorageV2
The answer is already zone in the answer explanation of the question but the picture is misleading.
Should be Zone
Agree, GRS replication to secondary region runs asynchronously.
Zone redundant, FO SHOW. :)
The site is good but questions like this one while you are reviewing the material doesn’t help. I understand you need to read carefully and so the explanation under the answer screenshot is good but the screenshot threw me off. Box 1: Zone-redundant storage (ZRS) Zone-redundant storage (ZRS) replicates your data synchronously across three storage clusters in a single region. LRS would not remain available if a data center in the region fails GRS and RA GRS use asynchronous replication. Box 2: StorageV2 (general purpose V2) ZRS only support GPv2.

The answer is Zone
box 1: Zone-redundant storage (ZRS) Box 2: StorageV2 (general purpose V2)
it should be Zone redundant
not sure if the stated info "ZRS only support GPv2." is correct ?
That's how it is stated in the AZ103 course from MS.
https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy
ZRS REPLICATES into 3 zones, one region. "However, ZRS by itself may not protect your data against a regional disaster where multiple zones are permanently affected. For protection against regional disasters, Microsoft recommends using geo-zone-redundant storage (GZRS), which uses ZRS in the primary region and also geo-replicates your data to a secondary region." "The primary difference between GRS and GZRS is how data is replicated in the primary region. Within the secondary location, data is always replicated synchronously three times using LRS."
Replicates synchronously. - LRS & ZRS Remains available if a single data center in the region fails. - ZRS, (RA-)GRS, (RA-)GZRS Only ZRS suports both requirements.

Came in exam
The correct is: ZRS with GPv2
Answer is correct, https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy because LRS and ZRS are redundancy options in Primary region Redundancy in the primary region Data in an Azure Storage account is always replicated three times in the primary region. Azure Storage offers two options for how your data is replicated in the primary region: Locally redundant storage (LRS) copies your data synchronously three times within a single physical location in the primary region. LRS is the least expensive replication option, but is not recommended for applications requiring high availability. Zone-redundant storage (ZRS) copies your data synchronously across three Azure availability zones in the primary region. For applications requiring high availability, Microsoft recommends using ZRS in the primary region, and also replicating to a secondary region.
You are wrong, they ask for synchronously replication, and the given answer was GRS that geo is asynchronously. So the correct answer is ZRS.
This question is tricky because with ZRS, data is replicated three times across 2 to 3 facilities with in the same/single region. It talk about just 1 datacenter fail. So ZRS still works fine. In theory GRS also works but at minimal you need ZRS
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 the secondary region. So in basic GRS = LRS with a asychrone copy to another region. Thats why the answer is ZRS
https://azure.microsoft.com/en-us/blog/azure-zone-redundant-storage-in-public-preview/
first answer is zone. 2nd one is correct.
GRS is incorrect: it runs asynchronously Correct is ZRS: Runs synchronously and keeps working in the case of a single datacenter (or availability zone) failure, but not in the case of an entire region failure.
First choice should be "zone-redundant storage" , 2nd choice is good.
I would go with ZRS over GRS. ZRS deals multiple availaity zones within the region. No one asked about replication to another region. So No need of GRS. Besides, GRS copies the data asynchronously in secondary Region.
Only the image is wrong. In detailed answer, it is ZRS and V2 which is correct..
came in exam. i think i answered wrongly. GRS...
ZRS not GRS
Answers: ZRS StorageV2
I feel proud when I see such answers from Admin and get verified 🤗
