AZ-104 · Question #670
You need to create an Azure Storage account named storage1. The solution must meet the following requirements: - Support Azure Data Lake Storage. - Minimize costs for infrequently accessed data. - Aut
The correct answer is B. the Cool access tire C. geo-redundant storage (GRS) E. hierarchical namespace. To support Azure Data Lake Storage, minimize costs for infrequently accessed data, and ensure automatic replication to a secondary region, the storage account needs a hierarchical namespace, the Cool access tier, and geo-redundant storage (GRS).

Why each option
To support Azure Data Lake Storage, minimize costs for infrequently accessed data, and ensure automatic replication to a secondary region, the storage account needs a hierarchical namespace, the Cool access tier, and geo-redundant storage (GRS).
Zone-redundant storage (ZRS) replicates data synchronously across availability zones within a single Azure region, not to a secondary region.
The Cool access tier is designed for infrequently accessed data, offering lower storage costs and higher transaction costs compared to the Hot tier, which directly helps minimize costs as required.
Geo-redundant storage (GRS) automatically replicates data to a secondary Azure region, providing disaster recovery capabilities and fulfilling the requirement for secondary region replication.
The Hot access tier is optimized for frequently accessed data and has higher storage costs than the Cool tier, which does not meet the requirement to minimize costs for infrequently accessed data.
A hierarchical namespace is a fundamental feature of Azure Data Lake Storage Gen2 that organizes objects into a hierarchy of directories and subdirectories, enabling efficient data management for analytical workloads.
