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

Case Study 1
A company has several independent business units that operate globally. The company has consolidated its IT infrastructure services and operations. Common infrastructural services which include IPAM, DNS, NTP, DHCP, and SMTP have been consolidated. The company has complimented its infrastructure development by investing in Dell EMC Isilon clusters to host its user’s home and group directories and for compliance archival purposes required by individual business units.
The IT operations are located in India and the United States with its primary data center facilities co-located between New York and Texas. The company has a total of 60 AD forests:

Users of different AD domains use different FQDN to access their corresponding file services. Additionally, the company does not plan to consolidate the AD domains and each domain uses a different IP subnet. The users of the domains with no trust relationships have a compliance archival requirement. The company wants to all data to be replicated between New York and Texas.
What is the minimum number of replication policies that are required to facilitate granular failover and failback capabilities for each AD domain?
- A. Only one replication policy per Access zone
- B. Two replication polities for each Access zone, one for regular data and one for the Smartlock directory
- C. One replication policy per Access zone with an additional replication policy for each SmartLock directory
- D. One replication policy for all data on the cluster
