What challenges are associated with NDMP backups in multi-tenant PowerScale clusters? (Select all that apply)
- A . NDMP context is limited to a single access zone at a time
- B . Backup streams may not scale linearly with node count
- C . NDMP requires CloudPools for tape integration
- D . NDMP automatically modifies SmartConnect failover settings
A customer has a 24-node PowerScale cluster, they need a solution that tolerates three node failures and four drive failures.
What protection level should be applied?
- A . +3n:1d1n
- B . N+3n
- C . +4d:2n
- D . N+4n
What challenge exists when configuring NDMP backups for multi-tenant clusters?
- A . NDMP cannot support incremental backups
- B . NDMP backups are restricted to a single access zone by default
- C . NDMP requires disabling SmartConnect zones temporarily
- D . NDMP cannot back up directories larger than 1 TB
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 . HDFS, SmartQuotas, SnapshotIQ, InsightIQ
- B . SmartPools, SnapshotIQ, SyncIQ, SmartLock
- C . InsightIQ, SmartPools, SyncIQ, SmartConnect Advanced
- D . SyncIQ, InsightIQ, SmartPools, Platform API

- B . Perfmon
- C . IOZone
- D . Iometer
