A customer has an SMB file directory with 375 TB of data on the primary cluster with a protection level of N+ 3:1. They want to replicate this directory to the secondary cluster. The customer would like information about the possibility of setting protection levels on the target cluster.
What information can be provided to the customer about the protection level for the target directory?

• A.Configured separately on the target cluster and does not need to match the source
• B.Controlled by SyncIQ and can be altered by the CLI
• C.Controlled by SyncIQ and cannot be altered
• D.Configured separately on the target cluster and must match the source

A customer wants to use their large Gen 6 Isilon cluster for ILM. All of their data is written to and read from a single file pool. They need to use multiple file pools, so slightly used data is stored on less expensive, large disks. Heavily used data is stored on a faster tier.
What would satisfy the customer's needs?

• A.Install SmartPools license on the cluster
• B.Configure SmartPools Advanced
• C.Add an A-series node with SmartPools license
• D.Enable FAST VP license on each node pair

How does Isilon SnapshotIQ use storage for snapshots?

• A.Through Changed Block Tracking and always uses a 4 KiB block, even if the data changed is less than that amount
• B.Works with 4 KiB blocks and will always use that amount of storage, no matter what has changed
• C.Through Changed Block Tracking and only changed data blocks are saved
• D.Works on the file level and saves the entire file no matter what has changed

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

You meet a customer for the first time. They explain that their current environment for NAS does not meet their needs. You want to make sure that Isilon is a good fit for their needs.
What would be a good prequalifying question to ask?

• A.How many users are in your Directory Services?
• B.What protocols are accessing your NAS?
• C.What application are you using to create directories?
• D.Is your datacenter ISO9001 compliant?
