Isilon Expert Solutions Exam
Question 1
You have been asked to design a Dell EMC Isilon cluster running OneFS 8.x for a service provider. One
of the most critical areas to the provider is data segregation with multi-tenants. Use the Launch
Simulator button to identify the current condition of the cluster: Note: It is necessary to close (x)
the simulator window to answer the question.

- D. Each non-System Access zone is connected to an individual groupnet with the same DNS server.
Answer:
A
Question 2
A Dell EMC Isilon administrator has reported that in Access zone ProdZone on the OneFS file
system nfs1, Microsoft Windows DEES\user1 has root level permission on nfs1. Use the Launch

Question 4
Case Study 3
A financial services company has file sharing workflows and 2000 home directories which include
70% Microsoft Windows and 30% Linux. The Security team is also interested in credit card usage data
analytics such as point of sale, geolocation, and authorization and transaction dat

information and must adhere to the U.S. SEC 17a-4(f) compliance standards. Additionally, they are
interested in auditing user access and anti-virus features.
The compute and storage environment consists of the following:
200 TB of Fibre Channel drives on NetApp ONTAP 7

Case Study icon shown below:
Case Study 5 Refer to the Exhibit.
Backing up data from a Dell EMC Isilon cluster exceeds the companys 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 companys 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. Enhance the backup strategy using snapshots tor backups
- B. Add A100 Backup Accelerators and configure for three-way NDMP
- C. Stop using an NDMP-based backup strategy
- D. Create a cron job to remove all locks before each backup

B

Question 10
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 users 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 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

-Average latency is 3 ms
Iperf shows:
-940 Mb/s average bandwidth
-005 ms average jitter
Netstat on the local network shows:
-05% average re-transmission rate
Hostcache list:
-20 ms average roundtrip time across all clients
The administrator shows you the following output from the netstat command:
32366653 data packets (35556615947 bytes)
