Highly available and resilient storage that often includes data encryption at rest and in transit is characteristic of which storage type?

The characteristic of highly available and resilient storage, combined with features such as data encryption both at rest and in transit, aligns closely with block storage. This type of storage is designed for environments that require high performance, low latency, and strong reliability, which are critical components in enterprise applications, databases, and virtual machines.

Block storage works by breaking data into blocks and storing them separately, allowing for rapid access and scalability. It is commonly used in cloud environments where reliability is paramount, and it often includes built-in data protection measures like snapshots and replication. Furthermore, block storage can be employed in configurations that support encryption features to protect data integrity and confidentiality during transmission and while stored.

The other storage types may offer some resilience but don't necessarily characterize the combination of attributes mentioned as strongly as block storage does. For example, direct attached storage is usually not scalable and lacks the network-based resilience found in block storage. File storage is great for sharing data among multiple users but may not provide the same level of performance or built-in resiliency. Object storage, while highly resilient and suitable for large unstructured data, often does not focus predominantly on high performance or low latency as block storage does. Thus, block storage is the most appropriate choice given the specifics of the question.
