EMC Dell PowerScale Design v2 - D-PSC-DS-01 Exam Practice Test

How many Z9264 switches are required for a A3000 cluster consisting of 160 nodes using a 25 GbE for a complete back-end network?

We have been engaged by a research hospital to help upgrade their Isilon installation. They currently have 12 previous generation Isilon nodes with 200 TB of capacity and run on a 1Gbps network.
They currently have 6 Illumina Hi-Seq Sequencers and an HPC cluster to process dat
a. They would like to expand Isilon to 2 PB of active data and 1 PB 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.
Before making any changes, the customer would like a graphical presentation of their existing array performance to present to management.
What is the best tool to gather this information?

A customer requires 4 PB of media storage with minimal space requirements and is concerned about drive rebuild times.
Which PowerScale capabilities address these concerns?

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

What are the available Usermapper roles?

Which factors must be considered when designing directory structures for large PowerScale namespaces? (Select all that apply)

The protection level of an Isilon Gen 6 cluster with eight nodes has been set to the default protection level.
How many failures are tolerated without data loss?

A customer has installed an Isilon Gen 6 cluster as a Proof of Concept. Before making a purchase decision, they would like to compare the performance of the Isilon to competitive offerings.
Which tool can be used to provide data analysis and benchmarking through existing workflows?

Which use cases are best suited for inline data reduction? (Select all that apply)

Your customer has an Isilon Gen 6 cluster with eight H400 nodes. During an unexpected power outage some of the nodes go offline simultaneously.
How many nodes need to remain up and communicating over the backend network to maintain a quorum in the cluster and still enable write access to the OneFS file system?

You have received a critical task that requires immediate analysis of system performance. Captured data will later be processed by MiTrend, but a current assessment is not available.
Which utility will quickly provide IOPS associated with reads and writes, CPU utilization, and I/O scheduler wait time?

Three jobs of different exclusion sets with a priority level of 5 are concurrently running on a cluster. A new job with a priority of 4 needs to be run.
What does the Job Engine do?
