EMC Dell PowerScale Design 2023 Sample Questions:
1. A telecommunications company has a substantial amount of data. 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.
Considering the customer's requirements, which is the best node type for the Isilon cluster?
A) NL400 with 48 GB RAM and no SSDs per node.
B) X400 with 24 GB RAM and 1.6 TB of SSD per node.
C) X200 with 24 GB of RAM and 1.2 TB of SSD per node.
D) X400 with 96 GB of RAM and no SSDs per node.
2. Refer to the exhibit.
A large hospital chain has approached you to redesign their storage infrastructure. The head of IT believes their requirement is for 60 TB of RAW capacity. The following are the notes from meetings with the department heads.
Which is the minimum cluster configuration that meets the customer's requirements?
A) 5 S-Series Nodes
B) 3 S-Series Nodes using SmartPools and 3 NL-Series Nodes for Archive
C) 3 NL-Series Nodes using SynqIQ to 3 NL-Series Nodes
D) 4 X-Series Nodes using SynqIQ to 4 NL-Series Nodes
3. What replication option is NOT supported by SyncIQ?
A) Across WAN to single remote cluster
B) Across LAN to secondary local cluster
C) Within the same local cluster
D) Across InfiniBand to secondary local cluster
4. A media and entertainment company has asked for help in creating a new Video On Demand (VOD) storage system. The storage would be delivered to 5000 subscribers simultaneously. They would like to store 5000 hours of full length, High Definition (HD) movies.
What would be the best price-to-performance nodes for this solution?
A) X400 with 1.6TB SSD and 24GB RAM
B) X400 with no SSD and 96GB RAM
C) Mixed X400 48GB RAM and NL400 24GB
D) X200 with no SSD and 48GB RAM
5. Which tool measures actual throughput and produces sophisticated graphs?
A) Perfmon
B) MiTrend
C) WireShark
D) IOZone
