EMC Dell PowerScale Design 2023 Sample Questions:

1. A customer has a 5 node Isilon cluster. The raw capacity of the cluster is 85% used. On average, the cluster has 4,000 users connected during office hours. The average CPU usage is 65%. The customer needs to delete some data to free up capacity.
What should the customer do to minimize the effect of the deletion job?

A) Delete the data from a client directly connected to the cluster
B) Run the treedelete job with a high impact and high priority during office hours.
C) Run the treedelete job with the default impact and priority during out-of-office hours.
D) Run the treedelete job with a high impact and high priority during out-of-office hours.

2. When installing nodes into a Dell EMC rack, which node type requires the use of a Titan-HD rack?

A) F800
B) A2000
C) H500
D) A200

3. Which OneFS roles should be assigned to an Active Directory group for login privileges equivalent to the 'admin' local account?

A) System Admin, AuditAdmin, and BackupAdmin
B) Security Admin and AuditAdmin
C) System Admin, BackupAdmin, and StatisticsAdmin
D) System Admin and Security Admin

4. 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) X200 with 24 GB of RAM and 1.2 TB of SSD per node.
B) X400 with 96 GB of RAM and no SSDs per node.
C) NL400 with 48 GB RAM and no SSDs per node.
D) X400 with 24 GB RAM and 1.6 TB of SSD per node.

5. You are sizing a PowerScale Gen6 cluster for a small organization that is concerned about the availability of the journal during an extended power outage.
What is a consideration when sizing?

A) Battery life within each node is a limiting factor.
B) Journal is written to nonvolatile storage if power is lost.
C) Journal is replicated to all nodes within a chassis.
D) Journal must be protected by an external UPS.
