A customer has a cluster consisting of six H700 nodes (in one full chassis and one half populated chassis) and four A2000 nodes (in one full chassis). The customer wants to expand their A2000 nodes.
What is the minimum number of A2000 nodes and chassis that the customer can add to the cluster?
Response:

• A. 4 nodes1 chassis
• B. 2 nodes1 chassis
• C. 2 nodes0 chassis
• D. 1 node0 chassis

What form of journaling redundancy is provided by a PowerScale Gen6 cluster?
Response:

• A. Each node maintains a copy of the peer journal.The local journal is saved on nonvolatile storage.
• B. Each node maintains a copy of the peer journal.The local journal is saved on battery backed-up storage.
• C. In the event of a node failure, the peer journal is written to disk on the paired node.
• D. In the event of a node failure, the peer journal is written to nonvolatile storage on the paired node.

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?
Response:

• A. - Expand the largest and most I/O intensive cluster using SmartFail- Consolidate the remaining two clusters using SyncIQ
• B. - 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
• C. - 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
• D. - Leave the clusters as is- Upgrade drive sizes to meet the customer requirements

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?
Response:

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

After raw events are processed by the CELOG coalescers, what happens to the data?
Response:

• A. Stored in the log databases and coalesced into event groups
• B. Stored in the audit host and coalesced into event groups
• C. Stored in the log databases and not coalesced into event groups
• D. Stored in the syslog host and coalesced into event groups
