Exam AZ-305 topic 3 question 10 discussion

v2+ ZRS

Guys, there are more datacenters in one Zone, Locally redundant means that there are more rooms with servers in datacenter. Zone redundant means that there are more datacenters (buildings) within one city/street -> ZR is enough.

Got this on may. 02, 2025 , Score 925, given answers are correct

Another question on the repeat cycle!

v1 is pricier than v2 therefore the v2 + ZRS

V2+GRS. V2 does not support ZRS.

Storage Account type - Standard general Purpose V2 Redundancy - GRS The archive access tier has the lowest storage cost. The archive tier isn't supported for ZRS, GZRS, or RA-GZRS accounts Additionally GRS offers 16 9's while ZRS offers only 12 9's https://learn.microsoft.com/en-us/azure/storage/blobs/access-tiers-overview

Standard v2+ ZRS (FROM: Brazil) ;-)

Ans: GPV2 and ZRS Premium Block Blob does not offer storage tier, always hot

1. Standard GPv2 2. ZRS https://learn.microsoft.com/en-us/azure/storage/common/storage-redundancy#zone-redundant-storage Zone-redundant storage (ZRS) replicates your storage account synchronously across three Azure availability zones in the primary region. Each availability zone is a separate physical location with independent power, cooling, and networking. ZRS offers durability for storage resources of at least 99.9999999999% (12 9's) over a given year. With ZRS, your data is still accessible for both read and write operations even if a zone becomes unavailable. If a zone becomes unavailable, Azure undertakes networking updates, such as DNS repointing. These updates may affect your application if you access data before the updates have completed. When designing applications for ZRS, follow practices for transient fault handling, including implementing retry policies with exponential back-off.

Answers are correct. Gv2 + ZRS

zone redundant storage doesn't help if single Azure datacenter fails it should be geo redundant storage

Correct!
