DP-203 dumps, about Redundancy in the primary region questions
You plan to implement an Azure Data Lake Gen 2 storage account.
You need to ensure that the data lake will remain available if a data center fails in the primary Azure region. The solution must minimize costs.
Which type of replication should you use for the storage account?
A. geo-redundant storage (GRS)
B. geo-zone-redundant storage (GZRS)
C. locally-redundant storage (LRS)
D. zone-redundant storage (ZRS)
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
Regarding the issue of primary area redundancy, the official Microsoft article is like this.
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 or durability.
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.
