A cloud administrator needs to reduce storage costs. Which of the following would best help the administrator reach that goal?
Options:
A.
Enabling compression
B.
Implementing deduplication
C.
Using containers
D.
Rightsizing the VMs
Answer:
B
Explanation:
Deduplication is a process by which redundant data is eliminated, thus reducing the size of the dataset. Deduplication with cloud storage reduces the storage requirements, along with the amount of data to be transferred over the network, resulting in faster and more efficient data protection operations1. Deduplication can help to shrink the data footprint, lower the storage costs, and improve the performance of backup and recovery processes2. Deduplication can be applied at different levels, such as file-level, block-level, or byte-level, depending on the granularity and efficiency of the technique3. Deduplication can also be performed at different locations, such as source, target, or cloud, depending on the architecture and design of the storage system3. By implementing deduplication, a cloud administrator can achieve significant data savings and optimize the cloud storage costs4.
