Protecting Data in Azure Storage Account with Locally-Redundant Storage (LRS)
Question
You have a general-purpose v1 Azure Storage account named storage1 that uses locally-redundant storage (LRS).
You need to ensure that the data in the storage account is protected if a zone fails. The solution must minimize costs and administrative effort.
What should you do first?

A. B. C. D.C
https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancyOption A: Create a new storage account.
Creating a new storage account will not help in achieving the desired solution as it will only create an additional storage account and the data will still be vulnerable to zone failure. Also, creating a new storage account will result in additional costs and administrative effort.
Option B: Configure object replication rules.
This option would help in achieving the desired solution as object replication rules provide the ability to replicate data to a secondary region, which would ensure data availability in case of a zone failure. However, this option is not the most cost-effective, as it requires an additional storage account in a different region and may result in additional administrative effort.
Option C: Upgrade the account to general-purpose v2.
Upgrading the account to general-purpose v2 will not help in achieving the desired solution, as it only provides additional features and functionality, but does not change the storage replication options.
Option D: Modify the Replication setting of storage1.
This option would help in achieving the desired solution as modifying the replication setting of the existing storage account to zone-redundant storage (ZRS) or geo-redundant storage (GRS) would ensure data availability in case of a zone failure. ZRS is the most cost-effective option, as it replicates data within the same region across two to three availability zones. On the other hand, GRS is more expensive as it replicates data to a secondary region, but provides additional data protection in case of a regional disaster.
Therefore, option D is the correct answer for this question, as it meets the requirements of minimizing costs and administrative effort while ensuring data availability in case of a zone failure.
