DP-900Domain 3: Describe Considerations for Working with Non-Relational Data on AzureNon-Relational Data on AzuremediumSingle choice
Backup archives must be retained for years and are almost NEVER read — lowest storage cost is the priority, and retrieval in hours is acceptable. Which Blob tier?
A.Hot
Hot is for frequent access — most expensive storage.
B.Cool
Cool is online — cheaper but not the cheapest.
C.Cold
Cold is still online retrieval — not archive pricing.
D.Archive
Offline + cheapest + rehydrate delay = Archive. Correct.
Why this answer
Archive = offline tier, cheapest GB/month, but data must be rehydrated (hours) before reading. Hot = frequent access; Cool/Cold = infrequent but still online. Rarely-read long retention + hours tolerance = Archive.
