An architect is designing a solution for a customer that is replicating data between two data centers 15 km apart from each other. The customer requires point-in-time protection.
What is possible in a SyncIQ policy?
- A . Copy source snapshots to remote cluster
- B . Replicate shares and exports on remote cluster
- C . Create snapshots on remote cluster
- D . Replicate cluster configuration data
A potential customer uses a solution from an EMC competitor for NFS storage in their main data center. The existing arrays are five years old, and the customer would like to consolidate them into a single new system.
The entire workload is generated by eight Linux hosts connected to the arrays that process video files. The customer informs you they are not able to collect performance information from the existing arrays.
Which tools can capture the workload requirements?
- A . iostat and nfsstat
- B . MiTrends and netmon
- C . netstat and esxtop
- D . Wireshark and sysstat
Which feature provides automated data efficiency improvements without user intervention?
- A . SmartDedupe with scheduled deduplication jobs
- B . Inline data reduction and compression in OneFS
- C . SyncIQ replication scheduling
- D . SmartLock WORM retention
Your customer has several departments that want separate access to the cluster so they can use their individual authentication methods. Two of the departments will use NFS and two will use SMB to access the cluster.
What would you recommend?
- A . Create two separate access zones for the SMB clients, and use the System zone for the NFS clients.
- B . Create separate access zones for both the SMB and NFS clients.
- C . Create two separate access zones for the NFS clients, and use the System zone for the SMB clients.
- D . Have all clients access the System zone, and use RBAC to control authentication.
Which three external authentication providers can be configured with Dell PowerScale? (Select 3)
- A . NIS
- B . AD
- C . LDAP
- D . SAML
- E . OAuth
An Isilon customer is experiencing less than expected performance and poor space utilization with their cluster. They are using the X400 nodes with an N+2d:1n protection policy to host web server log data.
Upon further analysis, the customer discovers that the web servers write log files 64KiB in size. The log files are then accessed by an analytics application for reporting purposes.
What should be done to increase the write performance of the cluster?
- A . Change the protection scheme to a mirroring policy
- B . Add S-Series storage nodes to the cluster
- C . Add A-Series Performance Accelerator nodes to the cluster
- D . Change the SSD strategy on the cluster
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
What would you recommend be done to consolidate the three clusters into one?
- A . – Expand the largest and most I/O intensive cluster using SmartFail
– Consolidate the remaining two clusters using Multithreaded version of RoboCopy
– Modify A-Record and propagate to all DNS servers to point to the new cluster - B . – Leave the clusters as is – Upgrade drive sizes to meet the customer requirements
- C . – Expand the largest and most I/O intensive cluster using SmartFail
– Consolidate the remaining two clusters using SyncIQ - D . – Build a new cluster for consolidation
– Use SnapshotlQ to migrate the existing data onto the new consolidated cluster
– Spoof DNS to point to the new cluster
A customer tiers a 2 GiB file to the cloud using CloudPools on OneFS 8.1.2.
Approximately how many cloud objects will be created for this file?
- A . 1,024
- B . 2,048
- C . 4,096
- D . 16,416
