Answer: A,E

Explanation:

Block storage, is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned. Both endurance and performance options provide a range of storage sizes, and the only difference between them is how the Input/Output Operations per Second (IOPS) is delivered for a given storage volume. – Endurance provides pre-set IOPS tiers of 0.25, 2, 4, and 10 IOPS/GB. – Performance allows the user to set a custom level of IOPS beyond 10 IOPS/GB. Under the virtual private cloud (VPC), block storage does not have endurance or performance tiers. Instead, users can set pre-defined or choose custom IOPS when provisioning the storage. Use Cases: Block storage suitable for low latency workloads where consistently high speeds required. Features: – Offer volume size from 20 GB to 12 TB, – Provide encryption for data at rest – Provide IOPS upto 48,000 IOPS – Highly available and resilient.
