NEW QUESTION 5
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 elements 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.
Which protocols would be the best fit when using Isilon for this customer's Hadoop workflow?

• A. NDMP and SCP
• B. NFS and HDFS
• C. CIFS and FTP
• D. SyncIQ and HTTP

Answer: B

NEW QUESTION 9
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 1PB of total storage
What would you recommend be done to consolidate the three clusters into one?

• A. • Expand the largest and most I/O intensive cluster using SmartFail• 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
• B. • Leave the clusters as is• Upgrade drive sizes to meet the customer requirements
• C. • Expand the largest and most I/O intensive cluster using SmartFail• Consolidate the remaining two clusters using SyncIQ
• D. • Build a new cluster for consolidation• Use SnapshotIQ to migrate the existing data onto the new consolidated cluster• Spoof DNS to point to the new cluster
