Question 15

locally redundant storage

Answer 15

lowest cost and least durable

zone redundant storage

Answer 16

replicates your data across three storage clusters in a single region. not available in all regions

Question 17

geo-redundant storage

Answer 17

replicated data in a separate region

Question 18

geo-zone redundant storage

Answer 18

you get zone redundant (3 storage clusters) and geo-redundant (secondary region)

blob storage hot

Answer 22

frequent reads and writes of objects. lowest access costs, highest storage costs

Question 23

Answer 23

large amounts of data that’s infrequently accessed. short tem back up and disaster recovery. 30 days minimum storage
