C1000-142 practice question 25 of 30

Which of the following are the characteristics of Block Storage?(Select Three)

Answer options

A: Block storage is suitable for applications where disk speed is important Correct answer

B: Block Storage normally mounted onto only one compute node at a time Correct answer

C: Highly available and resilient and will often include data encryption at rest and in transit Correct answer

D: Block storage is suitable for workloads where there needs to be some level of disk sharing between compute nodes Block storage is economical than the other types of storage

Correct Answer:

A. Block storage is suitable for applications where disk speed is important; B. Block Storage normally mounted onto only one compute node at a time; C. Highly available and resilient and will often include data encryption at rest and in transit

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. 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.
