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"

B. Read-only geo-redundant storage

B. Read-only geo-redundant storage

Key Tips: RA-GRS = Read access to secondary (for geo-failover or read scaling). GRS = No read access (only disaster recovery).

Read-Access Geo-Redundant Storage allows read access to the secondary location, in Geo-Redundant Storage there is no read access until failure

A does not allow to ready secondary region unless there is failure from first one. But question did not mention that restriction. "As well As first region", so it should be B

B is correct: Read Access Geo Zone Reduant Storage - 3x copies of data in seperate availability zones data centre - 3x copies in a secondary region (but one location) - Read access in secondary region even if primary region is functional - Read access in secondary region if primary region is down

New questions that was not from this series of 470 questions. 1. To group relative policy definitions in Azure, you should use Initiatives. I answered subscription groups which is wrong. 2. Scenario for locking for accidental deletion, i answered subscription level. 3. Then there was this question of Window 11, Ubuntu and Mac for using Azure CLI+Azure Portal+Azure Powershell.

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.

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
