Exam AZ-900 topic 1 question 2 discussion

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"

now give me answere Based on the given requirements: Data must be stored on multiple nodes. Data must be stored on nodes in separate geographic locations. Data can be read from the secondary location as well as from the primary location. The appropriate Azure storage redundancy option to recommend is: B. Read-only geo-redundant storage (RA-GRS) RA-GRS ensures data is replicated across geographically separate locations and allows for read access from both the primary and secondary locations, providing the necessary resiliency and availability.

i have started preparing and learning az-900 course .any leads of communities where people are ambitious about learning this az 900 would be helpfull and pls suggest me how better can i prepere this and source to study as beginner

Geo-redundant storage 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 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 or read-access geo-zone-redundant storage.

Correction, answer is A. There is no read only geo-redundant. Read-Access Geo-Redundant Storage (RA-GRS) is almost the same as GRS, but it provides read-only access to data in the secondary region during an outage in the primary region.

The answer is B (Read-only geo-redundant) Sign in to the Azure portal. Click on the Create a resource button. Select Storage Account from the list of available resources. Choose the subscription, resource group, and storage account name. Select Read-access geo-redundant storage (RA-GRS) as the redundancy option. Choose the primary region and the secondary region for replication. Choose the performance tier and the access tier for the storage account. Click on the Create button to create the storage account.

Read-only geo-redundancy alows the 3 main requirements. especially the last one

B. Read-access geo-redundant storage

"B. Read-access geo-redundant storage"

Is should be Read-Access not Read Only

Read-only geo-redundant storage

It should be B

The correct answer would be B. For read access to the secondary region, enable read-access geo-redundant storage (RA-GRS) or read-access geo-zone-redundant storage (RA-GZRS). Link to the reference: https://learn.microsoft.com/en-us/training/modules/describe-azure-storage-services/3-redundancy

Shouldn't be RA-GZRS (Read-Access Geo-Zone-Redundant Storage)? Cause it actually says that it need to be stored in multiple nodes, so it has to has the Zone Redundant aspect in it.

Option B. since by default, we cannot read from secondary region unless there is a failover. RA-GRS and RA-GZRS allows read option from secondary region without a failover.

B is correct Read access to data in the secondary region 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).
