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.

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.

it's answer A, for everyone that chose answer B, read carefully it says Read Only geo redundant storage, which doesn't exist, it's called Read Access only geo redundant storage, it's a trick question, and for that reason answer A is correct which is the closest to the requirements

CORRECT ANSWER: B Read-only geo-redundant storage 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).

The Correct answer is not actually provided. Correct answer here would be RA-GRS (Read Access Geo-Redundant Storage) Nothing about the description is requesting "read only"

B is correct

B. RA-GRS Because only this replication option provide read access to Secondary Region even when there is no failure in primary region. In case of GRS, only primary is available until there is no failure

sure of B

RA-GRS is correct

A. Geo-redundant storage (GRS): This option meets the requirements. It replicates your data to a secondary region, which is at least 400 miles away from the primary location. It provides read access to the data in the secondary region, allowing you to read from both the primary and secondary locations. B. Read-only geo-redundant storage: While it provides read access to the data in the secondary region, it doesn't meet the requirement of being able to read from both the primary and secondary locations. Therefore, it is not the best fit for the scenario. C. Zone-redundant storage: This redundancy option is designed to replicate data across multiple availability zones within a region for high availability but does not meet the requirement of separate geographic locations. D. Locally redundant storage: This option replicates data within the same region but not across separate geographic locations, so it does not meet the requirements. So, the correct answer is A. Geo-redundant storage (GRS).
