Exam AZ-104 topic 6 question 42 discussion

With GRS you can't choose the Destination region and for North Europe the paired region is West Europe so correct answer Object replication.

Object replication is a feature that allows you to replicate data, such as blobs, across different storage accounts or containers within the same storage account. This can be configured to automatically copy data from one storage location to another, either within the same region or across different regions. Object replication can be used to create disaster recovery solutions or to distribute data globally for better performance and availability. It is similar to GRS but it is more flexible as you can choose the storage account and container to replicate the data. The GRS of a North Europe region is a secondary copy of the data stored in a different region. The exact location of the secondary region will depend on the specific Azure region you have selected. For the North Europe region, the secondary copy is stored in the West Europe region. This means that if there is an outage or disaster in the North Europe region, your data will still be available in the West Europe region. This provides a high level of data durability and protection.

I think... the tricky part if the Administrative Effort. GRS will definitely require less administrative effort but It wont pick up East US region.

Why is GRS the preferred choice? Question Focus: The question explicitly asks for a solution that minimizes administrative effort, and GRS is designed for that. Once you enable GRS, Azure handles replication for you, without requiring you to configure or maintain additional rules. Default Region Pairing: While GRS doesn't allow you to specify the secondary region, Azure automatically replicates data to the paired region of the primary region. For North Europe, the paired region is West Europe. Hence, if you choose GRS, your data would actually be replicated to West Europe, not East US. Why not Object Replication? Object replication requires you to manually configure rules, specify the source and destination storage accounts, and ensure the target storage account is in the desired region (e.g., East US). While this approach offers control over the replication destination, it involves significantly more administrative effort, violating the "minimize administrative effort" requirement.

C: GRS While Object replication can indeed replicate blob data across different storage accounts, it requires more administrative effort compared to geo-redundant storage (GRS). With object replication, you need to manually configure replication policies and manage the replication process. On the other hand, geo-redundant storage (GRS) automatically replicates your data to a secondary region, providing durability and high availability with minimal administrative effort. GRS ensures that your data is always available, even in the event of a regional outage, without the need for manual configuration.

To achieve the desired outcome of creating a secondary copy of blob data in the East US region while minimizing administrative effort, you should configure geo-redundant storage (GRS) for your Azure storage account. Here’s why: Geo-Redundant Storage (GRS): GRS automatically replicates your data to a secondary region (in this case, East US) at a geographically distant location from the primary region (North Europe). It provides redundancy by maintaining multiple copies of your data across different data centers. If a failure occurs in the primary region, the secondary region ensures data availability without manual intervention. GRS is a robust solution for disaster recovery and data durability. Minimized Administrative Effort: With GRS, you don’t need to manually manage the replication process or set up additional configurations. Azure handles the replication transparently, reducing administrative overhead. Therefore, the correct answer is C. geo-redundant storage (GRS). Configure GRS for your storage account, and Azure will take care of maintaining the secondary copy in the East US region.

B is correct

B) Object replication GRS Pairing: North Europe is paired with West Europe http://azurecloud.expert/2018/01/08/azure-paired-regions/

I'd like to meet the person picking this answers for examtopics. what a shame

B. Enable Geo-Replication:

B is correct

The requirement here is to ensure that when blob data is added to storage1, a secondary copy is created in a different region, specifically in the East US region. The best solution for this is: B. Object replication Object replication in Azure allows you to set up replication of your block blob data from a source storage account in one Azure region to a destination account in another Azure region. You specify the source and destination regions, and can control replication at the level of a container, a virtual directory, or a blob. Geo-redundant storage (GRS) does replicate your data to another region, but it's not a selectable region, it's predetermined by Azure, so you can't choose East US specifically. The other options, operational backup and lifecycle management rule, do not replicate data across regions.

Agree with given answer, obj repl to alt created storage in required region. See; https://learn.microsoft.com/en-us/azure/storage/blobs/object-replication-overview Not C since that would replicate to paired region, see; https://learn.microsoft.com/en-us/azure/reliability/cross-region-replication-azure

Why is every question something else. Quite frankly I'm only interested in the "right" answer. It doesn't matter if B is applicable in real life if Microsoft is going to give me a fail and takes my money if I don't pass. What is the correct answer when taking the test? Having 3 options for every question I try to remember spreads doubt in my mind.

Excuse me, but you can't select the region when doing object replication either! You mean, you will need to create a storage account with the wished region and do the replication to that storage account.

B is the answer. https://learn.microsoft.com/en-us/azure/storage/blobs/object-replication-overview Object replication asynchronously copies block blobs between a source storage account and a destination account.

B is the correct answer :With GRS you can't choose the Destination region
