What is a benefit of using SSDs for Metadata Read/Write Acceleration?
Response:

• A.Does not need numerous SSDs to be effective
• B.Can be mixed with L3 cache on same node pool
• C.Improved create, write, and delete performance
• D.Guarantees data can be pinned to SSD

Your customer is looking for a storage solution that will be able to store seven million 3 MB files, which are written and seldom accessed. Read and write operations are both completed by a webbased application, which requires 1.3 Gbps throughput. The customer's network has not been upgraded in many years, so the network interfaces are 1Gbps.
Which cluster configuration would best meet the customer's requirements?
Response:

• A.3 NL400 nodes
• B.4 X200 nodes
• C.3 X400 nodes
• D.5 S200 nodes

For concurrent I/O, how do SmartCache and Endurant Cache differ?
Response:

• A.Endurant Cache sends an acknowledgement to the client immediately after mirroring writes in NVRAM
• B.SmartCache immediately commits the write to NVRAM on the local node and one peer node
• C.Endurant Cache waits for acknowledgement from all nodes before copying to L2 cache
• D.SmartCache uses sub-file, granular locking whereas Endurant Cache locks the entire file

You have been invited to meet with the Social Media and Marketing Department and gather requirements for a potential File System Project. They primarily use CIFS and are considering deploying a Hadoop cluster to analyze customer demographic dat a. The Senior Systems Engineer thinks they will need 2PB of usable capacity.
What would you do to gain an understanding of the customer's environment to qualify and develop the opportunity?
Response:

• A.Send the Social Media Team a sizing and features spreadsheet to complete; download the OneFS Architectural White Paper for them, and create a Logical System diagram in Visio
• B.Ask them to identify how the current data is accessed, where the data is accessed from, and who is accessing the data
• C.Create a cluster configuration specifying HDFS, NFS, and CIFS protocols; select 19 x X400 nodes with 144TB per node, and Enhanced Support
• D.Request the Windows Systems Administration Team run a PerfMon analysis on the Marketing Servers, consider adding 75 x 3TB drives to your VNX 5500, and contact the DBA Team for their help

A PowerScale cluster is configured with SmartConnect zones using dynamic IP address allocation. Failback is enabled. If there is a node failure, what happens to the IP address?
Response:

• A.IP address is moved to a new node, but the connection does not continue.
• B.The client must re-establish the connection to the node.
• C.IP address is no longer used, and a new connection must be made.
• D.IP address is moved to a new node, and the connection continues.
