Question 3 of 30
3. Question
What role does data deduplication play in optimizing storage efficiency and reducing storage costs?
Correct
Data deduplication is a storage optimization technique that identifies and eliminates duplicate copies of data, reducing storage capacity requirements and associated costs. By analyzing data at the block or file level, data deduplication identifies redundant data segments and stores only one instance of each unique segment, while subsequent references to the same data point to the existing instance. This eliminates redundant data copies and significantly reduces storage capacity requirements, leading to cost savings in terms of storage hardware and management overhead. Data deduplication does not increase storage costs by storing duplicate copies of data, as mentioned in option A. While data compression, mentioned in option B, is another storage optimization technique, it focuses on reducing the size of individual data blocks rather than eliminating redundant data copies. Option D describes caching mechanisms rather than data deduplication, which operates at the storage level to optimize storage efficiency.

Question 18 of 30
18. Question
When designing a disaster recovery (DR) plan for an organization, why is it important to establish recovery time objectives (RTOs) and recovery point objectives (RPOs)
Correct
Recovery time objectives (RTOs) and recovery point objectives (RPOs) are critical parameters in disaster recovery planning as they define the maximum acceptable downtime and data loss in the event of a disaster.
