Answer is correct. Geo-redundant storage (with GRS or GZRS) replicates your data to another physical location in the secondary region to protect against regional outages. However, that data is available to be read only if the customer or Microsoft initiates a failover from the primary to secondary region. When you enable read access to the secondary region, your data is available to be read at all times, including in a situation where the primary region becomes unavailable. For read access to the secondary region, enable read-access geo-redundant storage (RA-GRS) or read-access geo-zone-redundant storage (RA-GZRS).

I think it 's a mistake, it should be "B. Read-access geo-redundant storage" instead of "B. Read-only geo-redundant storage"

B. Read-only geo-redundant storage

B = RA-GRS is the correct answer

Para atender aos requisitos de armazenamento de dados descritos, você deve recomendar a opção: A. Armazenamento com redundância geográfica O armazenamento com redundância geográfica replica os dados em vários datacenters geograficamente separados, permitindo que você mantenha cópias dos dados tanto no local primário quanto no local secundário. Além disso, os dados podem ser lidos em ambos os locais, tornando-o adequado para cenários de resiliência do site em que você precisa de alta disponibilidade e capacidade de leitura em ambas as localizações geográficas separadas. As outras opções não atendem aos requisitos específicos mencionados, pois não oferecem a mesma combinação de resiliência geográfica e capacidade de leitura nos locais primário e secundário.

Answer B is correct: "Geo-redundant storage (with GRS or GZRS) replicates your data to another physical location in the secondary region to protect against regional outages. However, that data is available to be read only if the customer or Microsoft initiates a failover from the primary to secondary region. However, if you enable read access to the secondary region, your data is always available, even when the primary region is running optimally. For read access to the secondary region, enable read-access geo-redundant storage (RA-GRS) or read-access geo-zone-redundant storage (RA-GZRS)." https://learn.microsoft.com/en-us/training/modules/describe-azure-storage-services/3-redundancy

Given the data storage requirements you've provided, the most suitable Azure storage redundancy option would be: A. Geo-redundant storage Geo-redundant storage replicates your data to a secondary region, which is a separate geographic location. This meets the requirement of storing data on nodes in separate geographic locations. Additionally, geo-redundant storage allows you to read data from both the primary and secondary locations, which satisfies the requirement of being able to read data from the secondary location as well. The other options: B. Read-only geo-redundant storage: While this option provides read access to the secondary location, it doesn't store data on nodes in separate geographic locations. C. Zone-redundant storage: This option replicates data within a single region across multiple Availability Zones, but it doesn't meet the requirement of storing data in separate geographic locations. D. Locally redundant storage: This option replicates data within a single datacenter in a region, which doesn't fulfill the requirement of storing data on nodes in separate geographic locations. So, the recommended option is A. Geo-redundant storage.

the answer is B.

The correct answer is - A. Geo-redundant storage Geo-redundant storage meets all the specified requirements. With geo-redundant storage, data is stored on multiple nodes located in separate geographic locations. It provides redundancy across regions, ensuring high availability and data durability. In addition, data can be read from both the primary and secondary locations, allowing for access to the data even if one location becomes unavailable. B. Read-only geo-redundant storage does not fulfill the requirement that data can be written to and read from both the primary and secondary locations. C. Zone-redundant storage is designed for redundancy within a single Azure region, and it does not satisfy the requirement for geographic separation. D. Locally redundant storage does not meet the requirement of storing data on nodes in separate geographic locations.

The difference between GRS and RA GRS is fairly simple, GRS only allows to be read in the secondary zone in the even of a failover from the primary to secondary while RA GRS allows the option to read in the secondary whenever

The correct answer is A. There is no such thing as "Read-Only geo-redundant storage". Four aspects of the redundancy configuration of a storage account determine how your data is replicated and accessible: 1) Local redundancy - your data is always replicated three times within the local or primary region (LRS) 2) Zone redundancy - whether your data is replicated between different zones within the primary region (LRS vs. ZRS) 3) Geo-redundancy - replication within a single "local" region or between a primary and a secondary region (LRS vs. GRS) 4) Read access (RA) - read access to the secondary region when geo-redundancy is used (GRS vs. RA-GRS) The reason you'd pick GRS is because your data is written to your primary node and then replicated to the secondary node. Thus, the system does "write" to both even if the user only writes to one.

With GRS or GZRS, the data in the secondary region isn't available for read or write access unless there's a failover to the primary region. For read access to the secondary region, configure your storage account to use read-access geo-redundant storage (RA-GRS) or read-access geo-zone-redundant storage (RA-GZRS). answer: B
