HOTSPOT
You manage an Azure subscription.
You develop a storage plan with the following requirements:
+ Database backup files that are generated once per year are retained for ten years.
+ High performance system telemetry logs are created constantly and processed for analysis every month.
In the table below, identify the storage redundancy type that must be used. Make only one
selection in each column.
Answer: 
Explanation:
ZRS – it should be DB backup & for RA-GRS – also DB Backup.
GRS for DB “GRS is chosen by customers requiring the highest level of durability for Business Continuity Planning (BCP) by keeping their data durable in two regions hundreds of miles apart from each other in case of a regional disaster.”

Do you think that RA-GRS Could be used in this scenario, for cost purposes?
RA-GRS is costlier than GRS “In terms of pricing, the capacity (GB) charge is slightly higher for RA-GRS than GRS, whereas the transaction and bandwidth charges are the same for GRS and RA-GRS”
Yo don’t need high availibility for data in this scenario, so I’d discard RA-GRS for DB-Backup.

is the answer above is correct?
your copy and paste keys have been getting a work out.
I think it is correct.
RA-GRS is correct.
10 years is the trick part.
1 / 3650 = 99.97% > 99.9 ( GRS )
since RA-GRS is 99.99%, so we have to use RA-GRS.
Backups are generated once a year, not every day of the year.
There is no need for 99.97%
GRS for DB Backup is a good answer.
