Which of the following statements is correct?
DBFS is a file system protocol that allows users to interact with files stored in object storage using syntax and guarantees similar to Unix file systems. It provides familiar file system semantics and is designed to function like a traditional file system, which aligns with POSIX-like behaviors seen in Unix file systems.
A is correct . For E, This statement is partially incorrect. The DBFS root does use ephemeral storage, but not block volumes. Data saved there is lost when the cluster terminates unless explicitly persisted elsewhere. Mounted storage, however, can persist data between sessions depending on the underlying storage service and configuration.
DBFS is a layer on top of cloud storage providers.
it is not E. The only on that would be plausible is A
Databricks File System (DBFS) is a layer over a cloud object storage (like AWS S3, Azure Blob Storage, or GCP Cloud Storage) that allows users to interact with data as if they were using a traditional file system. It provides familiar file system semantics and is designed to be consistent with POSIX-like file system behavior, which includes commands and actions similar to those used in Unix and Linux file systems.
Answer is A
