Dell EMC DEE-1421 Isilon Expert Solutions Exam Practice Test

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 traceroute output

6 hops between clients and the cluster

Average latency is 84 ms

Based on the output, what information should be provided the administrator?

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 new data protection strategy. The company wants to:

Minimize the backup window

Increase the speed of data recovery

Reduce the network traffic

Reduce the overall growth of the backup datasets

The IT Team indicates that their currently backup hardware will be used in any solution. Which solution meets their requirements?

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 company is planning to replicate a dataset to a newly implement Dell EMC Isilon cluster. SyncIQ will used from the source to the target cluster. The company's system administrator wants to know how long the initial synchronization will take seeding. The administrator provides the following information:

Link speed between clusters is 1 Gb/s

Link speed efficiency is 85%

SynclQ domain sue is 125 TB

If no SynctQ performance rules are set, what is the estimated number of days?

You nave just configured a Dell EMC lsilon cluster. One of the remaining tastes is to enable alert notification. The cluster is on a network segment behind a firewall for security. You have determined which node is the CELOG master and have enabled connectivity between it and the ESRS gateway.

Testing shows that alerts were working for several days but have suddenly slopped. Which action is required to resolve this issue?

A company has a Dell EMC Isilon Gen 5 cluster with SSDs in each node. The administrator notices that L3 Cache is enabled on the cluster. However, the administrator does not notice any performance increase for the read I/Os. After further investigations, the administrator discovers that all read I/Os are more than 128K chunks.

Which recommendation should be provided to improve the read performance?
