Free EMC D-PSC-DS-01 Practice Test & Real Exam Questions

A customer has a cluster consisting of six H700 nodes (in one full chassis and one half populated chassis) and four A2000 nodes (in one full chassis). The customer wants to expand their A2000 nodes.
What is the minimum number of A2000 nodes and chassis that the customer can add to the cluster?

A customer has 10 files that are each 10 MB in size. They created two clones of each file on their source cluster. They now want to use SyncIQ to replicate the original files and the cloned files to a target cluster.
Excluding protection overhead, how much disk space will the files use on the target cluster?

A customer's cluster contains three X200 (24 GB RAM, 3 TB drives) nodes and three X400 (48 GB RAM, 1 TB drives) nodes, all configured in a single pool with N+2 protection.
After upgrading to OneFS 7.0, the web interface shows some files are not fully protected.
What should be done to correct this situation?

On Isilon Gen 6 nodes, what is used to store the peer journal copy?

When qualifying a CIFS + Hadoop analytics opportunity, what should be done to understand the customer environment?

Which data access patterns best match H500 home directory and A200 archive workloads?

What challenge exists when configuring NDMP backups for multi-tenant clusters?

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?

A healthcare provider must store genomic sequencing data with N+3 protection, not exceeding 75% utilization, and retain all patient data for seven years as per HIPAA regulations.
The initial requirement is 200 TB, growing at 30% per year.
Which initial configuration meets these requirements?

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 1 Gbps 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.
The customer will add two more Illumina Hi-Seq Sequencers in the next 6 months. Once these are added, what is the total amount of data from all the sequencers they can expect to add per month?

A customer is inquiring about expanding their primary cluster consisting of six S-Series nodes in order to improve performance. They have a second cluster with 11 X-Series nodes. Both clusters leverage 1GbE, but the customer recently installed a 10GbE network that can be utilized.
They also have multiple Fibre Channel SAN arrays in their environment. They have a variety of workloads on each cluster and are in the process of determining which workloads belong on which cluster.
They have discovered that one of the workloads- a SQL database that resides on the X-Series node cluster - is experiencing timeouts due to latency. The database vendor has suggested limiting latency to 5ms or less to eliminate these timeouts.
How do you advise the customer?

There is a concern that there are not enough physical switch ports available for the Isilon cluster in a new implementation with SMB and ICAP requirements.
What course of action should be taken?

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?

In a cluster with N+2 protection, which type of object would be triple mirrored automatically when written to the OneFS file system?
