• Question 136:

  An Isilon customer has two 5-node clusters; one for production and one for disaster recovery (DR). The customer's workflows are replicated to the DR cluster through SyncIQ on individual schedules. They have shut down their production cluster for scheduled maintenance, failed over to the DR cluster, and are currently operating from the DR site.

  Assume both clusters have identical shares, exports, user authentication. In addition, assume the client applications have been stopped and the DNS re-pointed. What is the easiest SyncIQ Policy method to continue operations on production?

  A. Initiate Automated Failback
  B. Revert
  C. Initiate Manual Failback
  D. No change is needed
  A. Initiate Automated Failback

• Question 137:

  A hospital is considering using Isilon to store their long-term archive data for their GE PACS application. They currently have two million 17 MB studies. They expect capacity requirements to be 50% compounded growth per year. They plan to use N+2:1 protection, and would like this sized for three years of growth.

  Which minimum cluster configuration would meet this customer's environment?

  A. Five NL400 (1 TB drive) nodes
  B. Four NL400 (2 TB drive) nodes
  C. Five X200 (3 TB drive) nodes
  D. Three X400 (3 TB drive) nodes
  A. Five NL400 (1 TB drive) nodes

• Question 138:

  At which level can retention periods be applied with Isilon SmartLock?

  A. Directory
  B. Node
  C. File system
  D. Cluster
  D. Cluster

• Question 139:

  You have been working with a customer to size a new Isilon cluster for their environment. You recently determined that a cluster with three X400 nodes with 1TB drives and 48 GB RAM would be a perfect starting point for their workflow, but will have extra capacity. The customer just informed you that they have decided to also use the cluster for a small home directory environment and implement SmartQuotas.

  Which configuration changes should you consider?

  A. Increase the memory and add SSDs to the configuration.
  B. Add an additional X400-Series node to the configuration.
  C. Add three NL-Series nodes with 1 TB drives with 48GB RAM, and use SmartPools.
  D. Add three S-Series nodes with 300GB drives with 48GB RAM, and use SmartPools.
  A. Increase the memory and add SSDs to the configuration.

• Question 140:

  A customer plans to deploy N+2:1 protection on a 5-node Isilon cluster. How much capacity will be used to store a 1024 KiB file?

  A. 1024 KiB
  B. 1280 KiB
  C. 1792 KiB
  D. 1920 KiB
  C. 1792 KiB
