You will be meeting with the Corporate Security Team as part of the implementation planning for a new Isilon cluster deployment. The Lead Security Analyst has asked you to discuss the Authentication Sources on your Isilon Cluster.
What customer questions regarding Isilon-supported Authentication Sources do you need to be prepared to answer?

• A.Is the cluster X.400 compliant?
  What firewall rules are in place to prevent data leakage?
  Is there a audit trail for access zone configuration changes?
• B.What mechanism are you using for NFS authentication?
  Do you have multiple AD domain support?
  What versions of LDAP are supported?
• C.What mechanism are you using for NFS authentication?
  Do you support Novell Directory Services?
  What implementations of LDAP are supported?
• D.Are you using File Services for UNIX in your AD environment?
  Do you support NIS+ for NFS authentication?
  Do you support multiple Access Zones connecting to the AD Domain?

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.Is your datacenter ISO9001 compliant?
• D.What application are you using to create directories?

An Isilon customer is reporting less than expected performance from the cluster and poor space utilization. The customer is using three X400 nodes with N+2:1 protection policy to host webserver log data. Upon further analysis, it is discovered that the webservers write log files 64 KiB in size. The log files are then accessed by an analytics application for reporting.
What should be done to increase write performance of the cluster?

• A.Add SSDs to the X-Series nodes in the cluster.
• B.Add S-Series storage nodes to the cluster.
• C.Change the protection scheme to a mirroring policy.
• D.Add A-Series performance accelerator nodes to the cluster.

You set up a meeting to gather information on a new project with the IT manager and plan to use a workflow profile assessment (WPA) to document the requirements.
Why is it recommended to talk to as many stakeholders as possible?

• A.Completing this document gives sales a list of who the stakeholders are at customer site.
• B.Helps downstream personnel, such as implementation and delivery, to have a clearer understanding of the requirements.
• C.Using the WPA tool will give you the best "big picture" to see things such as block size, de-dupe, file size and volumes.
• D.Using workflow profile enables sales to take this information to EMC consulting for review to validate the configuration.

Refer to the exhibit.

Your customer has three different clusters. File systems on two of the clusters are at 90% full, and the largest cluster is 10% full. Active data resides on the largest cluster. The customer has five different node types totaling 2PB and 54 nodes. Nodes from left to right are as shown:
1. X200
2.12000X
3.36000X
4.NL108
5.108NL
They have a Smartpool license and believe that tiering data would help free up needed space.
After talking with the customer and explaining the use of SmartPools, how would you recommend optimizing utilization across all of the nodes that the customer owns?

• A.Go to GUI and put alike nodes in the same pools. Then name them.
• B.Borrow nodes to reconfigure the cluster and migrate the data to new cluster.
• C.Explain to the customer that this will result in data loss.
• D.Attach all nodes to a common Infiniband switch.
