Isilon Infrastructure Specialist Exam for Technology Architects

Question 1

An Isilon customer created a scheduled SyncIQ policy to replicate data from an Enterprise-mode SmartLock directory. The source cluster becomes unusable. The target cluster does not automatically allow writes to the data in the replicated SmartLock directory.
What is the most likely reason the target cluster did not automatically allow writes of the data into the SmartLock directory?

A. Automated failover and manual failover are not allowed on SmartLock directories on the target cluster.

B. SyncIQ Automated failover is not supported for SmartLock directories; however, manual failover is allowed.

C. SnapshotIQ was not licensed on the target cluster; the snapshot of the directory is not available for use by SyncIQ.

D. A SyncIQ job was running while the source cluster became unusable, thereby removing all data in the target directory.

Correct Answer: B

Question 2

A customer wants an N+3 protection level on a cluster. What is the minimum number of nodes that needs to be purchased to achieve that level of protection?

A. 7

B. 3

C. 8

D. 6

Correct Answer: A

Question 3

A customer's Isilon storage administrator is concerned about capacity after recently ingesting 200 TB of file data. The customer has recently added more nodes to the cluster and wants to auto-balance the cluster as soon as possible. The cluster utilization percentages for an average 24hour period are:
-45% during 00:00 - 08:59 -60% during 09:00 - 17:00 -% during 17:01 - 23:59
While keeping cluster utilization at a minimum, which Impact Policy settings will allow the job to complete quickly without impacting the production workload?

A. Medium, Medium, Low

B. High, High, Low

C. High, Medium, Paused

D. Medium, Low, Low

Correct Answer: A

Question 4

You are assisting a customer with creating an Isilon solution that will address their needs while remaining cost-effective. The customer environment consists entirely of archive data. The data in their enterprise produces very little I/O and is only occasionally accessed.
Which Isilon storage node type will meet the customer's needs?

A. NL-Series node

B. Performance Accelerator node

C. X-Series node

D. S-Series node

Correct Answer: A

Question 5

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

A. SyncIQ only allows one job per node; this cluster can only run six SyncIQ jobs concurrently.

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

C. SyncIQ staggers the start of all SyncIQ jobs; jobs after the first job are delayed.

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

Correct Answer: B

Question 6

How can an Isilon cluster simplify a Hadoop workflow that analyzes large amounts of log data written to storage using FTP and where results are viewed by Microsoft Windows clients?

A. FTP, SMB, and HDFS NameNode and DataNode protocol support on the same file system enables each workflow step to access data from the same location avoiding data migration.

B. SyncIQ migrates the log data between an Isilon cluster and another Hadoop cluster, retrieves results from the Hadoop cluster, and stores them in an SMB share.

C. SmartConnect directs clients to an external Hadoop NameNode and to SMB shares so data ingest, analytics, and results phases are transparently directed.

D. FTP and SMB protocol support covers log ingest and Windows clients; SmartPools will stub to HDFS helping to reduce the frequency of external data migration.

Correct Answer: A

Question 7

Given a 7-node Isilon cluster configured with an N+2:1 protection level, how many nodes can be offline with the data accessible and fully writeable?

A. One

B. None; all nodes must be online

C. Three

D. Two

Correct Answer: A

Question 8

By default, how much space needs to be reserved for snapshots on an Isilon cluster?

A. 0% of the cluster

B. 10% of the cluster

C. 5% of the cluster

D. 20% of the cluster

Correct Answer: A

Question 9

In a supported cluster with the maximum protection level, how many simultaneous node component failures can Isilon OneFS sustain while still allowing full access to the entire file system and dataset?

A. 2

B. 1

C. 3

D. 4

Correct Answer: D
