Keep in mind the two options that Azure Storage provides for data replication in your primary region. The first is locally redundant storage. This is going to be the lowest cost redundant protection that you have within your storage account. So keep that in mind. Keep in mind that it protects against server and rack failures. It doesn’t protect against a, let’s say, data center failure. This is going to be a key distinguishing characteristic.
The second type we have is zone redundant storage. Now, this offers synchronous replication across three Azure availability zones. So now, if we lose one of our data centers, our data is still protected; and it’s still accessible.
Now, keep in mind that the two options that we have for Azure Storage provides for copying data to a secondary region.
Now, keep in mind that the two options we have for the different two, LRS versus ZRS, which one provides local protection?
Which one provides zonal protection?
This is going to be important for this part of your exam.
