A Dell EMC Isilon administrator has a 6-node X400 cluster. As the hardware is approaching end of service life, the administrator has planned for a technical refresh by replacing the 6-node X400 cluster with a 4-node H500 cluster.
The new 4-node H500 is added to the existing cluster and a SmartPools trial license is activated for data migration. The default location for the data and snapshots is changed in the default file pool policy from an X400 node pool to a H500 node pool. The SmartPool job is then run manually.

Case Study 5– Refer to the Exhibit.
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 method to increase the performance of their backups. After some investigations, you notice that the backup job quiesces the file system. This is creating lock contention issues on open files and not allowing users full access to data when the backup job runs.
What advice should be provided to the team to eliminate lock contention and allow full access to users?

• A. Add A100 Backup Accelerators and configurefor two-way NDMP
• B. Change the backup strategy to token-based backups
• C. Exclude the targets datasets from the backup job
• D. Create more parallel streams to utilize multi-stream NDMP backups

6 hops between clients and the cluster
Average latency is 84 ms
Based on the output, what information should be provided the administrator?

• A. Number of hops and average latencyis acceptable for the workflow
• B. Number of hops may indicate a weaknessinthe network model
