QUESTION 22
A potential customer requires 800 TB of usable capacity to store medical images for their network of health clinics. The IT department has limited staff and currently manages four storage arrays from other vendors. During a meeting with the Director of IT, you learn that the company is planning to deploy a scale-out NAS solution from a competitor of EMC. Which factors can demonstrate a lower TCO using Isilon?
A. An IDC study found that Isilon requires 95% less downtime per year compared to other competitors Isilon linear scalability closely aligns with additional staff requirements as capacity grows.
B. An IDC study found that Isilon requires 30% less downtime per year compared to other solutions Isilon linear scalability eliminates over buying and over provisioning.
C. An IDC study found that Isilon requires 95% less downtime per year compared to other competitors Isilon linear scalability eliminates over buying and over provisioning.
D. An IDC study found that Isilon requires 95% less downtime per year compared to other solutions Isilon uses lower speed NL-SAS drives which reduces overall power and cooling requirements.

QUESTION 23
An administrator recently installed InsightIQ to gather cluster statistics, and wants to look at file system usage (such as the number of files in a directory). However, currently no file system statistics are displayed in InsightIQ after 24 hours. Use of the cluster is moderate, and occurs 24 hours per day. What job for InsightIQ should the administrator modify to successfully report these statistics?
A. Change priority to 7 and job impact to Medium for SmartPools.
B. Change priority to 1 and job impact to High for Collect.
C. Change priority to 3 and job impact to Low for MultiScan.
D. Change priority to 4 and job impact to Medium for FSAnalyze.
Answer: D
QUESTION 24
A telecommunications company has a substantial amount of data. This data is being created by network elements within their environment. The company wants to change the way the network element’s Call Detail Records (CDR) are stored and analyzed. The existing infrastructure consolidates all of the CDRs into a table structure, and then ingests them into a large database. Once ingested, a query engine accesses the database and performs analysis on these files. The system is functional; however, since the amount of CDRs generated will increase exponentially over the next year, the company is open to alternatives for storing and analyzing these records. In evaluating alternatives, the key requirements are to reduce cost, the amount of storage, and the amount of time to analyze the data. The customer would like to use Hadoop to analyze the CDRs. After you have conducted an assessment of the workflow, you have recommended an Isilon Cluster to work within the Hadoop environment. What would be the best recommendation to the customer for the workflow of Hadoop with Isilon?
A. Copy the CDRs from the source to an Isilon cluster with NFS, then use Hadoop to analyze the information directly over HDFS.
B. Write the CDRs directly to an Isilon cluster with an NFS mount, then use Hadoop to analyze the information directly over HDFS.
C. Write the CDRs directly to an Isilon cluster with an NFS mount, then ingest the information into Hadoop with NFS, then analyze.
D. Copy the CDRs from the source to an Isilon cluster with NFS, then ingest the information into Hadoop for analysis.
Answer: B

B. X400 with 96 GB of RAM and no SSDs per node.
C. X200 with 24 GB of RAM and 1.2 TB of SSD per node.
D. X400 with 24 GB RAM and 1.6 TB of SSD per node.
Answer: B
QUESTION 27
Your customer manages a print media environment, consisting of three Isilon clusters, which are out of support. The customer would like to have access to new software releases and feature sets. You have been asked to perform a full discovery of the customer’s environment. The customer’s current Isilon clusters are as follows:
– “Cust” (12 x 12000X) serves as upload media storage for different tenants.
– “Working” (8 x 12000X + 6 x X200) serves as a working zone for extraction to RAW and printing media from it.
– “Archive” (16 x 72NL + Accelerator nodes) is used to store printed content for six months.
The customer operates in a Windows environment using SMB 2.0, two DNS servers per AD forest, three forest domains which are servicing three different environments. All servers are operating on a 1Gb network, three VLANs segregating the DEV/QA/PROD environments. Currently, there is no monitoring in place for performance measurement or optimization. The requirements for this solution include:
– Better ROI and TCO
– Maintain same performance with possible improvements
– Renew HW/SW and get inclusive support
– Limit migrations
– Reduce space, power, cooling consumption
– Get new feature sets
– If migration required, use Parallel copy (multiple nodes, multiple threads, multiple connections)
– Segregate tenant shares from other tenants
– Expand up to 1 PB of total storage
A. SyncIQ, InsightIQ, SmartPools, Platform API.
B. InsightIQ, SmartPools, SyncIQ, SmartConnect Advanced.
C. SmartPools, SnapshotIQ, SyncIQ, SmartLock.
D. HDFS, SmartQuotas, SnapshotIQ, InsightIQ.
Answer: B

What would you recommend be done to consolidate the three clusters into one?
A. Upgrade drive sizes to meet the customer requirements.
Expand the largest and most I/O intensive cluster using SmartFail.
B. Consolidate the remaining two clusters using SyncIQ.
Build a new cluster for consolidation.
C. Use SnapshotIQ to migrate the existing data onto the new consolidated cluster.
Spoof DNS to point to the new cluster.
Expand the largest and most I/O intensive cluster using SmartFail.
D. Consolidate the remaining two clusters using Multithreaded version of RoboCopy.
Modify A-Record and propagate to all DNS servers to point to the new cluster.
