EMC Dell PowerScale Design 2023 Sample Questions:
Question 1
A large manufacturing company is an existing Isilon customer with a cluster consisting of four NL400 nodes with 4TB drives. The cluster is using N+2:1 protection level and the file system shows that it is
60% utilized. Home directories and file shares comprise 75% of the existing content and the remainder is inactive deep archive. The company has 1,000 employees using Windows and Mac clients participating in a single Active Directory (AD) forest.
During a meeting with the CIO and Director of IT you discuss the company's recent acquisition - an engineering firm that specializes in Computer Aided Design (CAD). The engineering firm has 400 UNIX workstations that produce technical drawings which are currently stored on another vendor's SAN solution. The all UNIX environment uses NIS for authentication and name resolution. They do not currently use DNS or LDAP. The engineering company has an old storage system that has been experiencing problems and the CIO would like you to migrate the data onto the Isilon cluster. The CIO would like to eliminate all tape and recover the data onto disk.
The CIO is concerned about security of the company's intellectual property, especially with the rapid adoption of mobile devices and external cloud content sharing services such as DropBox, Egnyte, and SugarSync. They would like to implement an alternative that provides external file sharing and mobile device synchronization while maintaining security control over the company's data.
The Director of IT reports that users are storing non-work related content on the Isilon cluster. They would like to limit the amount of capacity that each user can consume in their home directory and want to ensure you provide the capability to easily visualize which users are over their allotment. The company's Windows users currently leverage Windows Shadow Copy to recover files that have been accidentally deleted. The IT department wants to ensure that Mac and incoming UNIX clients have the same functionality.
The Director of IT also mentions that users are reporting slow response times when browsing their home directories and shared folders. They are concerned that Isilon cannot scale to support their combined requirements.
The customer provides the following environment summary from the engineering firm's recently departed IT staff:
- 20 TB of Home Directory data
- 100 TB of active CAD projects
- 400 TB of archived data stored on tape at an offsite warehouse
Which configuration changes would you recommend for the Engineering users?
A. Mount an NFS share to a node on the Isilon cluster, being careful to equally distribute the load across nodes.
B. Create an FQDN for the Isilon cluster in the LMHOSTS file for each engineering system.
C. Utilize SMB2.1 protocol and mount to the Isilon cluster using the Name Server (NS) record IP.
D. Direct all clients to use the Manufacturing DNS server and connect NFS mounts to the FQDN of the Isilon cluster.
Question 2
What are the available Usermapper roles?
A. Active, Passive, and Standby
B. Primary, Secondary, and Client
C. Primary, Local, and Remote
D. Local, Remote, and Client
Question 3
Your customer manages a print media environment, consisting of three Isilon clusters, which are out of support. The customer would like to have access to new software releases and feature sets. You have been asked to perform a full discovery of the customer's environment.
The customer's current Isilon clusters are as follows:
"Cust" (12 x 12000X) serves as upload media storage for different tenants.
"Working" (8 x 12000X + 6 x X200) serves as a working zone for extraction to RAW and printing media from it.
"Archive" (16 x 72NL + Accelerator nodes) is used to store printed content for six months.
The customer operates in a Windows environment using SMB 2.0, two DNS servers per AD forest, three forest domains which are servicing three different environments. All servers are operating on a 1Gb network, three VLANs segregating the DEV/QA/PROD environments. Currently, there is no monitoring in place for performance measurement or optimization.
The requirements for this solution include:
- Better ROI and TCO
- Maintain same performance with possible improvements
- Renew HW/SW and get inclusive support
- Limit migrations
- Reduce space, power, cooling consumption
- Get new feature sets
- If migration required, use Parallel copy (multiple nodes, multiple threads multiple connections)
- Segregate tenant shares from other tenants
- Expand up to 1PB of total storage
Which licenses need to be defined for the solution to perform optimally?
A. SyncIQ, InsightIQ, SmartPools, Platform API
B. SmartPools, SnapshotIQ, SyncIQ, SmartLock
C. InsightIQ, SmartPools, SyncIQ, SmartConnect Advanced
D. HDFS, SmartQuotas, SnapshotIQ, InsightIQ
Question 4
How is data moved to the cloud using the CloudPools software module?
A. Data is transferred to cloud services based on CloudPools policy settings, leaving nothing on the Isilon cluster
B. Files are divided into 1 MB objects and stored in the cloud, leaving small stub files on the Isilon cluster
C. Data is transferred to cloud services and encoded based on the cloud configuration, leaving small stub files on the Isilon cluster
D. Files are divided into 1 MB objects and transferred over NDMP to the cloud service, leaving database entries on the Isilon cluster
Question 5
What must be configured on a PowerScale in order to store only the customer presentation PPT and PDF files on the cluster and the external repository?
A. Enable file filtering on the share repository, denying access to PDF and PPT file extensions.
B. Enable file filtering only on the share repository, denying access to PDF and PPT file extensions.
C. Enable file filtering only on the share repository, allowing only read-only PDF and PPT file extensions.
D. Enable file filtering on the share repository, allowing only write PDF and PPT file extensions.
