Block Storage Correct Answer-Data stored on a device in fixed sizes and access by the OS. No high level metadata is stored and is commonly deployed in SAN Block Volume Service Correct Answer-storage for compute instances. That is either for Boot or data disks. The service lets you store data independently of the lifespan of compute instances. Data is encrypted at rest and in transit Block Volume tiers Correct Answer-- Basic (for throughput intensive with large sequential I/O)
- Balanced (for most workloads including random I/O - boot disks)
- Higher Performance (most demanding I/O performance such as large DB) local NVMe Correct Answer-Temporary storage attached to compute instance. Used for applications that require high performance local storage such as transactional DB. It will survive a reboot. File Storage Correct Answer-Hierarchical collection of documents organized into named directories (local file systems) data is encrypted at rest and in transit FSS Correct Answer-File Storage Service Object Storage Correct Answer-All data stored in a 'bucket' and is managed as objects. Objects are stored in a single flat structure. Commonly used for Content repository, log data or archival backups.
