Read-access geo-redundant storage (RA-GRS) replicates your storage data to a secondary region and allows read access to the data in the event of an outage in the primary region. This ensures that the solution is resilient to regional Azure datacenter outages by providing both durability and availability of the data. This redundancy type is ideal as it ensures that the data remains accessible even if the primary region experiences an outage.
zone is part od a region, not vice-versa, so D can't be the answer
The question says if a data center goes down.. not if a region goes down. A region can host multiple data centers. So if one is down another data center from same region can take its place
"The solution must be resilient to regional Azure datacenter outages.". I believe that the given ans is correct.
"The solution must be resilient to regional Azure datacenter outages.". I believe that the given ans is correct.
Its does not say if "a" datacenter goes down, like in few previous question. given answer is correct.
I think the answer is correct; Answer should be (C) : geo-redundant storage Search for geo-redundant storage in the below link https://docs.microsoft.com/en-us/azure/databricks/scenarios/howto-regional-disaster-recovery
No it's D, zone redundant. The question states regional datacenter outages, not a whole region! Ref. https://docs.microsoft.com/en-us/azure/availability-zones/az-overview. "Availability Zones is a high-availability offering that protects your applications and data from datacenter failures"
blob storage does not support for ZRS.
Now, it does.
Now, it does.
correct answer - C
Yes D is the right answer as it says datacenter outage in a region. The jumbling of words is causing confusion here.
On the second though, we need RA-GRS to configure Databricks recovery - you'll have to remount all the data mounts therefore, you'll need your data available, therefore, RA is necessary. Unless you want to remount your data during the disaster recovery.
D is the correct answer. Gave the exam
how does giving the exam justify it when one doesnt know which ones are right..unless u got 100% :)
you cannot know, you cannot get 100%
The answer is correct, as it mentions "regional Azure datacenter outages". Thus the outages are for all the data center in a region, therefore ZRS can be ruled out. GRS is correct
D for region-wide outage C for region datacenter down correct: C
sorry otherwise - C for region-wide outage D for region datacenter down correct: D
I think its zone -> https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy
Services resiliency All Azure management services are architected to be resilient from region-level failures. In the spectrum of failures, one or more Availability Zone failures within a region have a smaller failure radius compared to an entire region failure. Azure can recover from a zone-level failure of management services within the region or from another Azure region. Azure performs critical maintenance one zone at a time within a region, to prevent any failures impacting customer resources deployed across Availability Zones within a region. seems it should be D - Zone Redundancy
While regional outage happen databricks cannot replicate to zone so we need to create in another region
But the question talks about regional datacenter outage. ZRS should suffice.
"regional Azure datacenter outages" it says regional. so how it would be ZRS? GRS is the answer.

They indeed recommend using geo-redundant storage. So it is answer C as suggested.
they reccomend geo-redundand because they are speaking of creating your own regional disaster recovery topology, the question is referring to a regional datacenter outage not a regional outage. a datacenter outage , the datacenter is inside a region, the solution to me is zone redundant (another datacenter in the same region)

C it is
https://docs.microsoft.com/en-us/azure/databricks/scenarios/howto-regional-disaster-recovery: "Use geo-redundant storage" Anyone would like to dispute this?
there is a difference between 1 datacenter and the whole region. Your link is a prove for ZRS
datacenter failure, so Zone-redundant storage
Zone-redundant storage (ZRS) replicates your Azure Storage data synchronously across three Azure availability zones in the primary region answer is D https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy
