Exam AZ-104 topic 1 question 12 discussion

B (A: "data will be available to be read-only if Microsoft initiates a failure", so its not RO if its not failed-over) Geo-redundant storage (GRS) As I explained above it helps us in replicating our data to another region which is far away hundreds of miles away from the primary region. It provides at least 99.99999999999999% (16 9's) durability of objects over a given year. GRS replicates our data to another region, but data will be available to be read-only if Microsoft initiates a failure from primary to the secondary region. Read-access geo-redundant storage (RA-GRS) It is based on the GRS, but it also provides an option to read from the secondary region, regardless of whether Microsoft initiates a failover from the primary to the secondary region.

Answer B. Read-access geo-redundant storage (RA-GRS) It is based on the GRS, but it also provides an option to read from the secondary region, regardless of whether Microsoft initiates a failover from the primary to the secondary region.

Because it can be stored on a geographically remote node and read from a secondary location

Correct

GPt Says The correct Azure storage redundancy option that meets the requirements is: A. Geo-redundant storage (GRS) Explanation: Geo-redundant storage (GRS) stores data across two geographic locations (regions), which aligns with your requirement to store data in separate geographic locations.

There is no read-only geo-redundant storage. It's called Read Access, it's a trick question. A is the correct answer. B should be correct if it stated the correct name.

B is correct

B is correct (RA-GRS)

Correct answer should be 'B'. GRS (Geo-Redundant Storage): Replicates data to a secondary region (typically hundreds of miles away). If the primary region fails, the data can be restored from the secondary region. RA-GRS (Read-Access Geo-Redundant Storage): Works like GRS, but with the additional capability that data can be read from the secondary region. This is useful for scenarios where you may want to access your data even if the primary region is down.

In Azure terminology, Read-Access Geo-Redundant Storage (RA-GRS) is sometimes referred to as "Read-Only Geo-Redundant Storage" because: Secondary Region Access is Read-Only: In RA-GRS, data replicated to the secondary region is accessible but only in read-only mode. This means users cannot modify the data in the secondary location—they can only read it. Write operations are still limited to the primary location. Distinction from Full Read-Write Access: The term "read-only" emphasizes that while you can access data in the secondary region, it’s not a fully writable, independent copy. Changes must still originate in the primary location, and then they’re asynchronously replicated to the secondary. Summary: So, "read-only" simply clarifies that while the secondary location provides access for reading, it’s not intended for active data modification, thus helping maintain data integrity across regions. Correct Answer: B. Read-Only Geo-Redundant Storage (RA-GRS)

B is correct

Read carefully, there is no such thing as Read Only - check out https://learn.microsoft.com/en-us/azure/storage/common/storage-redundancy

Based on the provided data storage requirements, the recommended Azure storage redundancy option would be: • A. Geo-redundant storage Explanation: Geo-redundant storage meets all the specified requirements: Data is stored on multiple nodes. Data is stored on nodes in separate geographic locations (Los Angeles and New York in this case). Data can be read from the secondary location (New York) as well as from the primary location (Los Angeles).

The answer is RA-GRS but in answer option it is said Read-only Geo Redundant Storage, which is not exists.Please confirm if the answere wording is correct , if it is then none of the answer matches the question

B. Read-only geo-redundant storage This option best meets the requirements because it stores data in a geographically distant location and allows for read access from the secondary location as well as the primary.
