Match each storage type to its characteristic.
Drag a concept onto its matching description — or click a concept then click the description.
Data stored as objects with metadata
Data divided into blocks; used in SAN
Data stored in a hierarchical file system
Temporary storage tied to instance lifecycle
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Object storage: Data stored as objects with metadata and a unique identifier, highly scalable.
Object storage uses objects with metadata (scalable for unstructured data), block storage uses fixed blocks (low-latency for databases), file storage uses hierarchical files (shared access), and SAN provides block-level access over a high-speed network. Common confusions swap object and block definitions.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Object storage: Data stored as objects with metadata and a unique identifier, highly scalable.
Why this is correct
Object storage is designed for unstructured data, using objects each with metadata and an ID, making it scalable.
Block storage: Data divided into fixed-sized blocks, commonly used for databases and virtual machines.
Why this is correct
Block storage breaks data into blocks and manages them independently, ideal for low-latency applications like databases.
File storage: Data organized in a hierarchical file system, accessed via file shares.
Why this is correct
File storage uses a tree-like directory structure, common in network file sharing protocols like NFS and SMB.
SAN: High-speed network connecting servers to storage, providing block-level access.
Why this is correct
A Storage Area Network (SAN) provides dedicated, high-performance block storage over a network.
Object storage: Data divided into blocks.
Why it's wrong here
Incorrect — this describes block storage, not object storage.
Block storage: Data stored as objects with metadata.
Why it's wrong here
Incorrect — this describes object storage, not block storage.
