A potential customer requires 800TB of usable capacity to store medical images for their network of health clinics.
The IT department has limited staff and currently manages four storage arrays from other vendors. During a meeting with the Director of IT, you learn that the company is planning to deploy a scale-out NAS solution from a competitor of EMC.
Which factors can demonstrate a lower TCO using Isilon?

• A.Isilon linear scalability eliminates over buying and over provisioning
• B.An IDC study found that Isilon requires 95% less downtime hours per year compared to other competitors
• C.An IDC study found that Isilon requires 95% less downtime per year compared to other solutions
• D.Isilon linear scalability closely aligns with additional staff requirements as capacity grows
• E.An IDC study found that Isilon requires 95% less downtime hours per year compared to other competitors
• F.Isilon uses lower speed NL-SAS drives which reduces overall power and cooling requirements
• G.Isilon linear scalability eliminates over buying and over provisioning
• H.An IDC study found that Isilon requires 30% less downtime per year compared to other solutions

A customer is evaluating PowerScale and NetApp FAS solutions. They are storing many unique files and want to understand how each solution deduplicates data.
What is the difference between how PowerScale and NetApp FAS deduplicate data?

• A.PowerScale does not have deduplication. NetApp FAS uses local deduplication.
• B.PowerScale uses separate deduplication at the volume level. NetApp FAS uses global deduplication across the cluster.
• C.PowerScale uses local deduplication. NetApp FAS does not have deduplication.
• D.PowerScale uses global deduplication across the cluster. NetApp FAS separates deduplication at the volume level.

Which cache type contains data blocks from previous read and write transactions?

• A.L2 cache
• B.L1 cache
• C.Metadata stored on SSDs
• D.L3 cache

How is the journal protected in Gen 6 hardware?

• A.Identical copy is maintained on both nodes of each node pair
• B.Each node has a mirrored M.2 vault
• C.Identical copy is maintained on all nodes of the cluster
• D.Each node has a mirrored write cache

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 1 Gbps.
What would be the best solution for this network configuration?

• A.Use jumbo frames to compensate for the 1GB Core network.
• B.Aggregate Infiniband (IB) ports across all nodes.
• C.Bond EXT-0 across all nodes.
• D.Use LACP to aggregate the network ports on each node.
