   A small business is considering implementing deduplication for their backup environment. They have a limited budget and want to reduce storage costs while maintaining fast backup and recovery. Which benefit of deduplication directly supports their cost-reduction goal?

   • AElimination of the need for offsite backups.
   • BIncreased backup frequency without additional storage.
   • CGuaranteed faster recovery times for all applications.
   • DReduced storage space requirements, leading to lower storage hardware and maintenance costs.

   An organization backs up to a remote data center over a 100 Mbps link. The backup data is highly redundant. After implementing source-side deduplication, the backup time drops from 8 hours to 2 hours. What is the primary reason for this improvement?

   • ALess data is sent over the network because only unique blocks are transmitted.
   • BThe backup window was extended to allow more time.
   • CThe backup software now uses compression, which speeds up data transfer.
   • DThe remote data center has faster storage after the change.

   A company is evaluating a backup solution that offers both deduplication and compression. They have a dataset that is highly redundant but not very compressible (e.g., already encrypted files). Which approach will yield the greatest storage savings?

   • ADeduplication only, because it eliminates duplicate blocks regardless of compressibility.
   • BCompression only, because it reduces the size of each block.
   • CBoth deduplication and compression, because they work together to maximize savings.
   • DNeither, because the data is already optimized.

   A company is considering implementing deduplication to reduce backup storage costs. They have a budget for new hardware and want to maximize the return on investment. Which factor should they consider when evaluating deduplication solutions?

   • AThe replication speed, which affects disaster recovery.
   • BThe compression ratio, which is more important than deduplication.
   • CThe deduplication ratio, which indicates how much storage is saved.
   • DThe encryption strength, which ensures data security.

   A backup administrator is troubleshooting slow restores from a deduplication appliance. The backups are deduplicated, but restores take longer than expected. What is a likely cause?

   • AThe backup data is not compressed.
   • BThe backup target is a tape library.
   • CThe deduplication index is fragmented, causing longer lookup times.
   • DThe backup software is not configured to use the deduplication appliance.
