Zorluk: KolayConfigure Blob Storage Lifecycle and Replication

An administrator is reviewing replication options for standard General Purpose v2 (GPv2) storage accounts in an Azure subscription.

Which of the following statements about Azure Storage replication options are correct? (Select TWO.)

  1. Locally-redundant storage (LRS) replicates data synchronously three times within a single physical location in the primary region.Cevap
  2. Read-access geo-redundant storage (RA-GRS) provides read-only access to the data in the secondary region under normal operating conditions.Cevap
  3. C
    Geo-redundant storage (GRS) provides read-only access to the data in the secondary region without requiring a failover.
  4. D
    Zone-redundant storage (ZRS) replicates data asynchronously across three Azure availability zones in the primary region.
  5. E
    Changing the replication configuration from locally-redundant storage (LRS) to zone-redundant storage (ZRS) can be performed directly without data migration using the Azure portal.

Cevap

Locally-redundant storage (LRS) replicates data synchronously three times within a single physical location, and Read-access geo-redundant storage (RA-GRS) provides read-only access to the data in the secondary region under normal operating conditions.
Locally-redundant storage (LRS) is designed to replicate data synchronously three times within a single physical location in the primary region, providing cost-effective local redundancy. Read-access geo-redundant storage (RA-GRS) adds read-only access to the secondary region by exposing a secondary endpoint, enabling read capabilities without requiring a failover.

Adım Adım Çözüm

1
Identify the replication mechanism of Locally-redundant storage (LRS).
LRS replicates three copies of the data synchronously within a single facility (data center) in the primary region.
This confirms the statement about LRS is correct.
2
Evaluate the read access capabilities of Geo-redundant storage (GRS) and Read-access geo-redundant storage (RA-GRS).
RA-GRS provides read access to the secondary region at all times, whereas GRS does not allow read access to the secondary region unless a failover is initiated.
This confirms the statement about RA-GRS is correct, and the statement about GRS is incorrect.
3
Verify the synchronization model of Zone-redundant storage (ZRS).
ZRS replicates data synchronously across three availability zones in the primary region.
This disproves the statement claiming ZRS replicates asynchronously.
4
Check the migration requirements for converting LRS to ZRS.
Converting LRS to ZRS cannot be configured as a simple update in the portal; it requires requesting a live migration or performing a manual data copy.
This disproves the statement claiming LRS to ZRS conversion can be done directly in the portal.
