EMC Dell PowerScale Design v2 Sample Questions:

1. 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) Add A-Series Performance Accelerator nodes to the cluster
B) Change the SSD strategy on the cluster
C) Add S-Series storage nodes to the cluster
D) Change the protection scheme to a mirroring policy

2. While validating the value (VTV) with a large educational customer, they have decided they would like to add a Disaster Recovery (DR) site to their existing Isilon environment. The existing cluster contains six X-Series nodes.
They plan to have all workflows replicated to the DR site and both clusters will have identical shares, exports, and user authentication. The customer would like to test DR failover every six months by running their production environment from the DR site.
What would you recommend for the DR solution?

A) SyncIQ and NL-Series nodes at the DR site
B) Equal number of S-Series nodes at the primary site
C) SyncIQ and identical cluster at the DR site
D) SmartConnect and NL-Series nodes at the primary site

3. A new PowerScale cluster servicing SMB and NFS data must use dynamic link aggregation to maximize throughput and resiliency.
Which physical network configuration is recommended?

A) Active/passive failover
B) FEC
C) Round robin
D) LACP

4. A customer has grown 2 PB in the last year. The cluster performs well most times of the day, but occasionally during the day, the customer notices a decrease in performance. You have been told that 'tree-deletes' are taking too long and can only be run on weekends.
What would you recommend to speed up the 'tree-deletes'?

A) Add 20% more nodes to the cluster to help with degraded performance.
B) Use an A100 node for added CPU performance to help with 'tree-deletes.'
C) Add an SSD tier for metadata, ensuring all nodes have SSDs.
D) Add an SSD node tier for metadata to account for at least 2% of RAW capacity

5. What key considerations should be kept in mind when designing a 300TB solution?

A) Always include 2% SSD SmartPools Smartconnect Snapshots InsightIQ
B) Workflow management Defining class of service Time of day services RPO and RTO Data retention and backup
C) SmartPools Smartconnect Snapshots Space for snapshots
D) Defining class of service Time of day services ROI and TCO Data retention and backup
