EMC D-PSC-DS-01 Actual Free Exam Questions & Community Discussion

You get a call from a customer that has just added 200 user connections to the cluster. They want to know how fast they are writing data with these new users.
What tool would you use to gather this information?

Which tool measures actual throughput and produces sophisticated graphs?

A customer has two PowerScale clusters. Cluster1 has eight H700 nodes, and Cluster2 has twelve A300 nodes. The customer wants to monitor real-time performance data of both clusters and track file growth.
Which tool should be recommended?

Match each PowerScale feature with its primary purpose:
1. SmartLock
2. SmartPools
3. CloudPools
4. ZRBAC
Options:
a) WORM compliance and data retention
b) Automated tiering between node pools
c) Offloading cold data to cloud storage
d) Zone-specific role-based administration

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?

You are reviewing an opportunity with a trusted advisor. You both discover gaps in the initial solution design. Each iterative discussion with the customer helps you define the solution better. The documents produced capture the customer's requirements.
What else needs to occur to refine the sizing considerations?

A company has data protection and recovery requirements that include:
- Point-in-time images of data
- Local data protection
- Directory level granularity
- Manual or scheduled operation
- Minimal storage to maintain
Which Isilon feature satisfies all requirements?

A customer configures a file pool policy to write data to tier 2 on the Isilon cluster. This is in addition to the 30 policies already created. Later in the week they check the file placement and see that it has not been written to the correct tire.
What could be the problem?

Your customer is moving from a Restaurant/Bar business model to a Restaurant/Casino business model. You are helping architect the upgrade of a current 4-node X200 48 TB Isilon cluster, with 50% utilized for their video surveillance operations.
They want to upgrade from 15 FPS (NTSC) in H.264 codec, with a 15 days retention policy to 30 FPS (NTSC) in H.264 codec with a 30 days retention policy.
Which storage capacity would be the best suited to meet the required changes and utilize 65-75% capacity?

In OneFS, what is the largest number of disks in a subpool?

What consideration is most important when sizing for mixed streaming and transactional workloads?

Match each monitoring tool with its primary use:
1. InsightIQ
2. isi statistics
3. tcpdump/Wireshark
4. Job Engine Options:
a) Real-time cluster performance metrics
b) Historical trending and capacity analytics
c) Packet-level network capture and analysis
d) Scheduling and throttling background tasks

A customer wants an N+3 protection level on their cluster.
What is the minimum number of nodes they need to achieve that level of protection?

An Isilon customer has acquired a company with its own AD and DNS infrastructure. A request is made to consolidate the data from a number of servers at the acquired company onto the existing company's Isilon cluster.
What is the least disruptive way to do this?

A telecommunications company has a substantial amount of dat
a. This data is being created by network elements within their environment. The company wants to change the way the network elements Call Detail Records (CDR) are stored and analyzed.
The existing infrastructure consolidates all of the CDRs into a table structure, and then ingests them into a large database. Once ingested, a query engine accesses the database and performs analysis on these files. The system is functional; however, since the amount of CDRs generated will increase exponentially over the next year, the company is open to alternatives for storing and analyzing these records.
In evaluating alternatives, the key requirements are to reduce cost, the amount of storage, and the amount of time to analyze the data. The customer would like to use Hadoop to analyze the CDRs. After you have conducted an assessment of the workflow, you have recommended an Isilon Cluster to work within the Hadoop environment.
What would be the best recommendation to the customer for the workflow of Hadoop with Isilon?
