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.Round robin
• B.FEC
• C.Active/passive failover
• D.LACP

Your customer, a metropolitan newspaper, uses Secure FTP (SFTP) to upload stories and images for print workflows. Their existing competitor's storage array is going out of support, and future SFTP support is being dropped.
This SFTP workflow is not covered in their disaster recovery plan.
Which qualifying questions would uncover this requirement early?

• A.What is your network infrastructure? How many storage fabrics do you have? What is your disaster recovery plan?
• B.What protocols (SFTP, SMB, NFS) are in use? What does your infrastructure look like? How do you manage file systems?
• C.What is your infrastructure? What applications access the storage? What protocol versions are in use?
• D.How much capacity is required? What applications access the storage? What risks exist in your infrastructure?

When would SmartPools and file pool policies be most beneficial?

• A.In an environment where all nodes have identical performance and capacity
• B.For managing snapshot schedules across multiple access zones
• C.For automatically placing data based on its attributes such as file type or last accessed time
• D.To create unique DNS domains for different tenants

Your customer's initial use case was Home Directories. They implemented the cluster with four 1Gbps ports and LACP. They are planning to expand their cluster to support their core file services. They plan to upgrade their network infrastructure to 10 GbE to facilitate this.
What are two design impacts this change will have?

• A.LACP and multiple links may be used to increase redundancy, but will not provide more overall performance to the system. FCoE should be considered for the External Network Ports on the nodes.
• B.Maximum performance is obtained by only using a single 10GbE interface per node. Isilon can support up to 400MB/s per node
• C.Dual 10GbE ports on each node will enable throughput of 20Gbps. Only connect half of the nodes to the network.
• D.Maximum performance is obtained by only using a single 10GbE interface per node. LACP and multiple links may be used to increase redundancy, but will not provide more overall performance to the system.

A customer needs to consolidate 300 TB of home directory servers and shared file systems used by development and test groups. A key requirement is to prevent the systems from consuming all free capacity and impacting home directory content.
Which Isilon node configuration should be proposed?

• A.NL-Series with SmartQuotas
• B.X-Series with SmartQuotas
• C.S-Series with InsightIQ
• D.X-Series with SmartPools
