Question 2

Your company has datacenters in Los Angeles and New York. The company has a Microsoft Azure subscription.

You are configuring the two datacenters as geo-clustered sites for site resiliency.

You need to recommend an Azure storage redundancy option.

You have the following data storage 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

Which of the following Azure stored redundancy options should you recommend?

    Correct Answer: B

    Read-only geo-redundant storage (RA-GRS) is the appropriate choice as it stores data on multiple nodes in separate geographic locations and allows data to be read from both the primary and secondary locations. This meets the requirements for high availability and resiliency by ensuring that data is always accessible, even if the primary location fails, without the need for initiating a failover like in standard geo-redundant storage.

Discussion
BinuRajOption: B

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).

scabOption: B

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

AntonioTechOption: A

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.

"Geo-redundant storage allows you to read data from both the primary and secondary locations", but according to Microsoft, "only if the customer or Microsoft initiates a failover from the primary to secondary region." With how this question is worded, A can be technically correct, but B allows for better availability. Although if you choose RA-GRS, the data from the 2nd region is always readable. Also how can you say RA-GRS "doesn't store data on nodes in separate geographic locations"? That defeats the purpose of calling it GRS, no?

Soumyat85Option: A

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.

"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", but according to Microsoft, "only if the customer or Microsoft initiates a failover from the primary to secondary region." RA-GRS (Option B) provides more availability. "RA-GRS does not fulfill the requirement that data can be written to and read from both the primary and secondary locations." None of the requirements mention that both primary and secondary locations should be "written to" at the same time. You CAN write to both, but only if one location "initiates a failover". Both GRS and RA-GRS supports this. Source: https://learn.microsoft.com/en-us/training/modules/describe-azure-storage-services/3-redundancy

guru_jiOption: B

the answer is B.

Stel0Papad4Option: B

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.

PPV20Option: B

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.

ipereiraOption: B

answer is B

SAFMOption: B

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

RVAadminOption: B

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

shahrzadkhbOption: 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

MAFA56Option: B

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).

thej_raaaaasOption: B

specially it has multiple location, and data should be read form

AparnaBavanariOption: A

Geo-redundant Storage

Octy7408Option: B

B. Read-only geo-redundant storage

LoneJandoOption: B

B = RA-GRS is the correct answer

Du_MS900Option: A

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.
