Question 21

A customer is running OneFS 8.0 on an Isilon cluster consisting exclusively of NL400 nodes. The storage administrator recently heard that OneFS 8.1 provides journal vaulting.
What should you advise the storage administrator?

A.Migrate all data from the current Isilon cluster to a Gen 6 cluster.

B.Add SSDs to all nodes of the existing cluster and upgrade to OneFS 8.1.

C.Replace the batteries of the battery backed volatile storage with NiMH batteries.

D.Add a Gen 6 node to the existing Isilon cluster and upgrade to OneFS 8.1.

Question 22

A customer created eight SyncIQ policies on a 6-node Isilon cluster. The policies all start at midnight. The customer is experiencing issues where several jobs are paused while others continue to run. This is delaying the overall replication of data.
What is the most likely reason for the pausing of some of the SyncIQ jobs?

A.An Isilon cluster can only have five concurrent SyncIQ jobs running at the same time.

B.An Isilon cluster can only have one SyncIQ job running at any one time.

C.SyncIQ only allows one job per node. This cluster can only run six SyncIQ jobs concurrently.

D.SyncIQ will stagger the start of all SyncIQ jobs. Jobs after the first job are delayed.

Question 23

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 S-Series storage nodes to the cluster.

B.Add A-Series performance accelerator nodes to the cluster.

C.Change the protection scheme to a mirroring policy.

D.Add SSDs to the X-Series nodes in the cluster.

Question 24

When designing Isilon solutions, what issues should you pay special attention to?

A.Avoid being too enthusiastic over the technology Balancing technical and business requirements Provide Options Design to meet customer expectations
