You are the architect of Contoso airliners. You have been tasked to design the storage for a new application. The application requires storage that is going to be accessed infrequently and must be available across several datacenters. Which storage type should be used with optimal cost-benefit in mind?
General-purpose V2 cool tier access is correct, as this is ideal for storage of data that is accessed infrequently which makes it cost-effective and supports availability across datacenters. General-purpose V2 hot tier is used for data that is accessed regularly which makes it slightly more expensive than cool tier storage and it also supports availability across datacenters. Premium SSD will not suffice as this storage option only supports Local Redundant Storage. General-purpose V1 does not support hot/cool tier access.
