Question 1

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 details of the hostcahce.list output. The output indicates that the top clients on the list have an average of 242 ms round trip time. Based on the output, what information should be provided to the administrator?

AOnly the aggregate of all average round trip bines will indicate an issue

BRecalculate and re-populate round trip uses by using the isi_cbind clear commend

CAn increase in the average round trip time indicates a network problem

DAn average round trip time less than 300 ms is the acceptable range

Answer : A

Question 2

A company has three Doll EMC Isilon X200 nodes and needs to configure two Subnets on the cluster. The production subnet will only me a 10 GgE-1 port from each subnet will use both ext-1 and exl-2 ports on each node. The company will access each subnet with its SmartConnect zone name

Given that the second subnet is isolated with no route to the DNS server, how many IP addresses are needed for each subnet lo accommodate the requirements?

A3 for production and 7 for isolated

B4 for production and 6 for sorted

C4 for production and 7 for isolated

D6 for production and 4 for isolated

Answer : D

Question 4

A company's HPC environment is using Dell EMC Isilon Gen 6 nodes. They have additional throughput requirements and have asked for your recommendations. The environment consists of two subnets:

Mgmt-subnet: 1x1-GigE interface in the ''mgmt-pool'' for management traffic on a VLAN-tagged management network in an Isilon default System Access zone.

Data-subnet: 2x10-GigE aggregated interfaces in the ''data-pool'' for data traffic on a VLAN-tagged data network in an Isilon user-defined data Access Zone

Which recommendation should be provided?

ARemove VLAN tagging from f e network

BMove the data pool into the System Access zone

CUse different groupnets for management and data traffic

DUse only one subnet and pool for both the management and data traffic

Answer : C

Question 5

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?

AEnable Global Name Space acceleration in addition to L3 Cache

BChange the SSD strategy to 'data on SSD'

CDisable L3 Cache and change the SSD strategy to 'metadata-road acceleration''

DAdd one more SSD of equal capacity to each node

Answer : C

Question 6

A media company has a Microsoft Windows-based infrastructure and uses Adobe media editing tools to create advertisements for its customers Users from the Media Production department store all types of media ties on a Dell EMC Isilon cluster.

In addition, users from the Support department are not allowed to store MP3 and AVI files to the NAS system. Both the Media Production and Support departments need to access other common data on the cluster. Due to workflow procedures, the media files are stored on the same path on me Isilon cluster.

The company wants to Know which ision features are available and can restrict the Support department users from writing certain media file types onto the Isilon cluster. Which recommendation should be provided/

ACreate a single SMB share for both departments
Use the share security settings end Windows NTFS settings to restrict the types

BCreate an SMG snare for the Support department and restrict the Media Production department users from accessing the share
Create another SMB share for Via Media Production department and apply file Altering

CCreate a separate Access zone for each department
Use Sync 10 to replicate the data and exclude the media files

DCreate a SMB snare for me Media Production department and restrict the Support department users from accessing the share
Creole another SMB share for the Support department and apply file filtering

Answer : A

Question 7
