Zorluk: KolayConfigure Blob Storage Lifecycle and Replication

An administrator has an Azure Storage account named store1 that currently uses locally redundant storage (LRS). The administrator must configure replication to protect the data against a regional outage. Additionally, the data in the secondary region must be available for read access before any failover is initiated. Which configuration should the administrator use?

  1. A
    Configure the storage account to use geo-redundant storage (GRS).
  2. B
    Configure the storage account to use zone-redundant storage (ZRS).
  3. Configure the storage account to use read-access geo-redundant storage (RA-GRS).Cevap
  4. D
    Assign the Storage Blob Data Reader role to users specifically for the secondary region endpoint.

Cevap

Configure the storage account to use read-access geo-redundant storage (RA-GRS).
Configuring the storage account to use read-access geo-redundant storage (RA-GRS) satisfies both requirements. It replicates data to a secondary region to protect against a regional disaster, and it provides a secondary read-only endpoint that is accessible to clients before any failover is initiated.

Adım Adım Çözüm

1
Identify the primary requirement: replicate data to a secondary region to protect against a regional outage.
Locally redundant storage (LRS) and zone-redundant storage (ZRS) are ruled out because they keep data within the primary region.
LRS replicates within a single datacenter, and ZRS replicates across zones in a single region. Neither replicates to a secondary region.
2
Identify the secondary requirement: the replicated data in the secondary region must be read-accessible before failover.
Standard geo-redundant storage (GRS) is ruled out because it does not support read access to the secondary region prior to failover.
RA-GRS (Read-Access Geo-Redundant Storage) must be chosen because it explicitly enables a read-only endpoint in the secondary region while keeping primary and secondary data synchronized.

Anahtar Kavram

Selecting the correct Azure Storage replication option based on durability, geographical distribution, and read availability requirements.
