Question 1

A Dell EMC Isilon administrator has a 6-node X400 cluster. As the hardware is approaching end of service life, the administrator has planned for a technical refresh by replacing the 6-node X400 cluster with a 4-node H500 cluster.

The new 4-node H500 is added to the existing cluster and a SmartPools trial license is activated for data migration. The default location for the data and snapshots is changed in the default file pool policy from an X400 node pool to a H500 node pool. The SmartPool job is then run manually.

After the SmartPool job is finished, the X400 node pool still consumes approximately 10% of the storage.

What is a possible reason for this issue?

ASyncIQ migration method should have been used

BManually-managed files and directories still exist

CSmartPools mat license is not sufficient, a W license required

DSmartPool job finished with errors. Dell EMC Support needs to be contacted

Answer : B

Question 2

What enables CloudPools to achieve a retail of data from the cloud?

ACreating a copy file for every file whose data is archived to the cloud

BCreating a HardLink file for every die whose data is archived to me cloud

CCreating a SmartLink file for every file whose data is archived to the cloud

DCreating a SoflLink file for every file whose data is archived to the cloud

Answer : C

Question 3

A company has a cluster with two subnets. 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?

AConfigure static routes tor both subnets

BEnable source-based touting

CEnable destination based routing with static routes

DChange the gateway priorities

Answer : D

Question 4

A company has an 8-node X410 installed as a single Dell EMC Isilon cluster. The company expressed concerns about cluster performance, particularly about NFS being slow. The output shown in the exhibit was presented to the Dell EMC technician.

Based on this output, what is a reason for the cluster performance issue?

ASmartConnect is not properly balancing the connections

BAverage NFSv3 write latency is too high

CToo many namespace_read operations against the cluster

DNumber of I/O for a single node is too high

Answer : A

Question 5

A company has an existing Dell EMC 4-node X410 Gen 5 cluster with approximately 100 TB of SMB shares connected using two InfiniBand 8-port switches The company wants a technical refresh of the cluster with a new 4-node H5O0 Gen 6 cluster with two 16-port InrmiBand switches The existing cluster has SynclQ. SmartConnect Advanced and Smart Ports licenses installed

To move me data from the existing nodes to the new nodes, which migration plan is recommended?

AModify the default tile pool policy to move the data
Swap the existing InfiniBand switches with the new switches

BSetup a new cluster with the new Gen 6 nodes and its InfiniBand switches
Use SynclQ to migrate the data and then SmartFail the existing cluster

CSetup a new cluster with the new Gen 8 nodes and the InfiniBand switches
Use EMCopy to migrate the data and then use 'sharedup' to create the shares

DAdd the new nodes to the existing cluster.
Modify the default file pool policy to move the data and then SmartFail the existing nodes

Answer : D

Question 6

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 7

The DobiMigrate used to migrate data from a third-party platform to a Dell PMC isilon cluster less than 50 GB of NFS, SMB, and multi-protocol data will be migrated. What are the minimum requirements for the migration?

ACore serve and no proxy servers

BCore server and one proxy server

CCore server and two proxy servers

DCore server and three proxy servers

Answer : C
