Blobs should automatically move to Cool after 30 days untouched and to Archive after 180 days — no manual intervention. What implements this?
A.Object replication policy
Object replication copies blobs between accounts — doesn't change tiers.
B.Lifecycle management policy
Lifecycle policy = age-based tiering/deletion automation. Correct.
C.Immutable storage policy
Immutability prevents modification — nothing to do with tiering.
D.AzCopy scheduled task
AzCopy is a transfer tool, not a lifecycle engine.
Why this answer
Lifecycle management policies are rule-based automation: tier blobs (Hot→Cool→Cold→Archive) or delete them based on last-modified/last-accessed age. The standard 'automatic tier transitions' answer.
