                                                  Backing up data from a Dell EMC Isilon cluster exceeds the company's backup window. Because the company has a large amount of data with a continuous high growth rate, they want to change their backup strategy. The Gen 6 Isilon cluster consists of 24 nodes. Their current backup strategy is an NDMP three-way backup performing weekly full backups to tape and incremental backups each night. The strategy uses Dell EMC NetWorker. The DMA uses Include paths to specify what data to backup. All data on the cluster must remain accessible.
                                                  The company's IT team is now looking for a new data protection strategy. The company wants to:
                                                  * Minimize the backup window
                                                  * Increase the speed of data recovery
                                                  * Reduce the network traffic
                                                  * Reduce the overall growth of the backup datasets
                                                  The IT Team indicates that their currently backup hardware will be used in any solution. Which solution meets their requirements?

                                                  • A. Increase the backup tape block size to 512 KB
                                                  • B. Configure the DMA to use IPv6 for better performance
                                                  • C. Implement an incremental forever backup strategy
                                                  • D. Change the backup strategy to token-based backups
