In low risk environments, what is the cost-effective replication factor for Block Storage?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

In low-risk environments, a replication factor of 2 is considered cost-effective for block storage. This means that each piece of data is stored in two separate locations. This level of redundancy allows for the preservation of data in the event that one of the storage nodes fails, enhancing the reliability of the system without incurring the higher costs associated with greater replication factors. Choosing a replication factor of 2 strikes a balance between security and cost. It provides adequate protection against data loss due to hardware failure while minimizing the additional storage costs compared to options with higher replication factors. Higher replication factors, such as 3 or 4, while offering increased safety, would lead to significantly increased overhead in storage requirements and therefore would generally not be justified in a low-risk environment. Using a replication factor of 1 would not provide any redundancy, making it unsuitable even in low-risk contexts.
