EMC D-PSC-DS-23 Actual Free Exam Questions & Community Discussion

Your customer has a new business unit. They are gathering web log files to be analyzed. They are using Hadoop to do the analysis of the logs. The IT department is centrally storing the log files on a 5- node Isilon cluster.
They have enabled the Hadoop cluster to access the files directly on the Isilon storage. The nodes are X400's with two SSD drives in each node and 96GB of RAM.
How many DataNodes does the Isilon cluster have?

A customer is experiencing problems writing data to their PowerScale cluster. You have checked all network settings and authentication sources. No errors are reported on the cluster.
Which command can the customer use to collect information about network activity, network packets, and network latency?

A customer has a data retention period of three years. They want a solution in which files cannot be deleted, changed, or modified.
Which Isilon SmartLock version should they implement?

A customer has two Isilon clusters in an Active-Passive setup. The customer has latency sensitive media editing workflows. Most of the media editing work occurs prior to broadcasting between 7:00-8:00,
11:00- 12:00, 17:00-18:00 and 19:00-20:00.
What should be recommended to minimize the risk of including latency to the client workflow?

Which SmartConnect policies are used for workloads that have short lived connections such as HTTP and FTP?

An Isilon cluster has two ports configured per node. Each port is on a different VLAN. Although incoming traffic is evenly distributed, transmitted data from the Isilon uses one port more than the other port.
What could be the cause of this imbalance?

We have been engaged by a research hospital to help upgrade their Isilon installation. They currently have 12 previous generation Isilon nodes with 200TB of capacity and run on a 1Gbps network. They currently have 6 IIlumina Hi-Seq Sequencers and an HPC cluster to process data.
They would like to expand Isilon to 2PB of active data and 1PB of archive data. They use a third party data and metadata management service (IRODs) to stage data for analysis. The Isilon cluster is mainly used for analysis work with the HPC cluster. The customer has a limited budget.
What would be the best price/performance solution for their active data?

What is the behavior of the Isilon time and date settings and what is the best practice?

An Isilon storage administrator is concerned about capacity after ingesting 200 TB of file data. They recently added more nodes to the cluster and now want to auto-balance it as soon as possible.
The cluster utilization percentages for an average 24-hour period are:
- 45% during 00:00 - 08:59
- 60% during 09:00 - 17:00
- 85% during 17:01 - 23:59
The administrator wants to keep cluster utilization at a minimum.
Which Impact Policy settings should be used to quickly complete the job without impacting the production workload?
