Exam DP-203 topic 1 question 58 discussion

I am surprised you all missed this requirement 'Ensures that content remains available for writes if a primary data center fails'. RA-GRS and RAGZRS provide read access only after failover. The correct answer is ZRS as t=stated in the link below "Microsoft recommends using ZRS in the primary region for Azure Data Lake Storage Gen2 workloads." https://learn.microsoft.com/en-us/azure/storage/common/storage-redundancy?toc=%2Fazure%2Fstorage%2Fblobs%2Ftoc.json

Failover initiated by Microsoft. Customer-managed account failover is not yet supported in accounts that have a hierarchical namespace (Azure Data Lake Storage Gen2). To learn more, see Blob storage features available in Azure Data Lake Storage Gen2.

Use customer-managed failover options to develop, test, and implement your disaster recovery plans. Do not rely on Microsoft-managed failover, which might only be used in extreme circumstances. A Microsoft-managed failover would be initiated for an entire physical unit, such as a region or a datacenter. It can't be initiated for individual storage accounts, subscriptions, or tenants. If you need the ability to selectively failover your individual storage accounts

RA-GRS and failure initiated by Microsoft

Region wasn't mention in the question, so how did you guys come about it? Answer: ZRS and Failover initiated by Microsoft.

Failover Process: Failover initiated by Microsoft: In this scenario, Microsoft would initiate the failover process, which might not meet the requirement for maintaining availability for writes during a failure. CORRECT: Failover manually initiated by the customer: Allows the customer to control when the failover happens, ensuring that writes can be directed to the secondary region during a primary region failure. Failover automatically initiated by an Azure Automation job: This could provide automation for failover, but it may not give the same level of control as manual initiation by the customer.

Zone redundant, microsoft initiated

Should be: - ZRS because the question talk about on a failure on the primary region for Azure Data Lake Storage Gen2 Workloads, so a Zone. - Failover initiated by Microsoft.

Type Failover Scope Use case Expected data loss HNS supported Customer-managed Storage account The storage service endpoints for the primary region become unavailable, but the secondary region is available. You received an Azure Advisory in which Microsoft advises you to perform a failover operation of storage accounts potentially affected by an outage. Yes Yes (In preview) Microsoft-managed Entire region or scale unit The primary region becomes completely unavailable due to a significant disaster, but the secondary region is available. Yes Yes

Your disaster recovery plan should be based on customer-managed failover. Do not rely on Microsoft-managed failover, which might only be used in extreme circumstances. A Microsoft-managed failover would be initiated for an entire physical unit, such as a region or scale unit. It can't be initiated for individual storage accounts, subscriptions, or tenants. For the ability to selectively failover your individual storage accounts, use customer-managed account failover. https://learn.microsoft.com/en-us/azure/storage/common/storage-disaster-recovery-guidance#microsoft-managed-failover

"Provides the highest degree of data resiliency" and it didn't meantioned about the cost. I think GZRS will be the one to go for and it is microsoft initiated failover

RA-GZRS Failover manually initiated by the customer

Why is the ET Azure community so divided for most of the Multiple Correct Questions? This was not the case for GCP ET community.

Failover initiated by Microsoft: In general, automatic failover initiated by Microsoft is the best option for most organizations, as it is the most reliable and efficient. However, if you need more control over the failover process, then you can choose to use automatic failover initiated by an Azure Automation job. RA-GZRS Available using RA-GZRS. RA-GZRS replicates data asynchronously to a secondary data center in a different Azure region. This means that there is a longer latency for replication, but it also means that your data is protected from regional outages. Additionally, RA-GZRS supports data compression and encryption, which can further improve storage efficiency.

accroding to microsoft Documentation: https://learn.microsoft.com/en-us/azure/storage/common/storage-disaster-recovery-guidance it mentioned 1-Customer-managed -- scope--> Storage account-- Case--> The storage service endpoints for the primary region become unavailable, but the secondary region is available. You received an Azure Advisory in which Microsoft advises you to perform a failover operation of storage accounts potentially affected by an outage. 2-Microsoft-managed-- Scope--> Entire region or scale unit -- Case--> The primary region becomes completely unavailable due to a significant disaster, but the secondary region is available. in the question it talks about Storage i.e. Data Center not a region failure. so the anwer is Customer managed

anser is correct. RA-GZRS (Read Access Geo Zone Redundancy) provides read AND WRITE and has the highest availability (16 9's). https://learn.microsoft.com/en-us/azure/storage/common/storage-redundancy#geo-zone-redundant-storage For failover: iniciated by customer. In Microsofr case they MAY failover only if greater disaster happens. https://learn.microsoft.com/en-us/azure/storage/common/storage-disaster-recovery-guidance?toc=%2Fazure%2Fstorage%2Fblobs%2Ftoc.json&bc=%2Fazure%2Fstorage%2Fblobs%2Fbreadcrumb%2Ftoc.json#microsoft-managed-failover

GZRS Because it mentioned that when a data center failed, not the entire region. When a data centre failed, with ZRS, we can still read and write to the other two datacentres in the same region. So for the primary region, it must be ZRS. We still need a backup for the secondary region because it reqiures the highest degree of data resiliency. Customer Managed Failover, No Doubt!!!
