Which two types of replication can you use for the storage account? (DP-900)
You need to create an Azure Storage account.
Data in the account must replicate outside the Azure region automatically.
Which two types of replication can you use for the storage account? Each correct answer presents a complete solution.
A) zone-redundant storage (ZRS).
B) read-access geo-redundant storage (RA-GRS).
C) locally-redundant storage (LRS).
D) geo-redundant storage (GRS).
Solution
Correct answer: B) read-access geo-redundant storage (RA-GRS) and D) geo-redundant storage (GRS).
Read-access geo-redundant storage (RA-GRS) replicates your data to a secondary region asynchronously. This secondary region is typically hundreds of miles away from the primary location and is used for read access during primary region outages. It provides enhanced availability for your data.
Geo-redundant storage (GRS) also replicates your data to a secondary region, but it synchronously copies your data to three separate locations within the secondary region for higher durability. It is a robust solution for disaster recovery scenarios.
Both options ensure that your data is replicated outside the Azure region automatically, meeting the requirement specified.
