NEW QUESTION 1
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:
1 main domain
55 domains have one-way trust relationships with the main domain
An additional 4 domains do not have any trust relationship with no future plans of establishing trust relationships with the other domains.
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 groupnets required?

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 investigation, you notice that the backup job targets two paths. This could be the cause of the lengthy backup times.
What advice should be provided to the team?

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