EMC Expert - Isilon Solutions - DEE-1421 Exam Practice Test
A company has a cluster with twosubnets. The first subnet has 1GbE interfaces dedicated for management and the second subnet has 10GG interfaces dedicated for handling all data access. When the cluster started serving the prediction environment. Poor performance was observed while the data is accessed through the data subnet. White troubleshooting the network the administrator discovered that the return traffic is going through the management network.
Which recommended solution will rescue this issue?
Which recommended solution will rescue this issue?
Correct Answer: A
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 Situation" button to examine the environment and validate the reason for this condition. Note: It is necessary to "close" (x) the simulation windows to answer the question.
Based on your findings, what is the reason for the condition?

Case Study 4
A company is experiencing a noticeable decrease in performance when accessing data on their Dell EMC Isilon cluster. The cluster hosts Microsoft Windows home directories and general purpose file shares. In addition, a file pool policy moves data that has not been modified in six months to an achieve tier. The administrator wants your assistance in understanding the reason for the slow data access. The number of users accessing the cluster has not changed.
The administrator has shared the following baseline metrics. The outputs were captured from a performance- acceptable time frame.
Trace route shows:
-3 hops between clients and 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 thenetstatcommand:
* 32366653 data packets (35556615947 bytes)
* 8010 data packets (9525723 bytes) re-transmitted
Based on the output, what information should be provided to the administrator?

Acompany has 7 PB of PACS archivedata on their Dell FMC Isilon cluster. The PACS application currently creates and stores large containers of small files. Based on local healthcare regulation changes, the company can no longer use large containers of small files. As a result, the company wants to know if Isilon can support the new regulatory PACS requirement while maximizing the storage capacity for small tiles Which licensed feature should be activated?
Correct Answer: C
