You will create a storage account named storage1 with a file share named share1. Ensure share1 supports SMB Multichannel while minimizing cost. Which storage configuration should you choose?

SMB Multichannel for Azure Files is only supported on Premium file shares. Therefore, a Premium performance tier is required. To minimize cost while meeting this requirement, Locally-Redundant Storage (LRS) is the most economical redundancy option. Standard performance tiers do not support SMB Multichannel. Geo-redundant storage (GRS) and Zone-redundant storage (ZRS) provide higher data durability and availability but at a greater cost than LRS, and are not necessary given the "minimizing cost" constraint if LRS is sufficient.
