Why each option
Azure Table storage implements the key-value model, storing data as schema-less entities identified by a partition key and a row key.
Azure Queue storage implements a message queue model for asynchronous communication between application components, not a key-value store.
Azure Files implements a shared file system model using SMB and NFS protocols, not a key-value model.
Azure Table storage is a NoSQL key-value store that organizes data as entities, each uniquely identified by a composite key consisting of a PartitionKey and a RowKey. It is schema-less, meaning each entity can have a different set of properties, making it a direct implementation of the key-value data model within Azure Storage.
Azure Blob storage implements an object storage model for unstructured binary and text data, organized in containers, not a key-value model.
