BThree X400 nodes with 1TB drives

CTwo NL400 nodes with 4TB drives

DTwo X400 nodes with 3TB drives

Answer : A

Question 4

A customer plans to migrate data to a remote Isilon cluster. What is a consideration when configuring a cluster

with SyncIQ and hard SmartQuotas?

ASyncIQ ignores quota limits during replication but if a quota is over limit, quotas will still allow users to add
data to the directory.

BQuotas should be configured on both SyncIQ source and target directories prior to a migration.

CSyncIQ will replicate source quota configurations to the target.

DQuotas should be set only on source directories and never on target directories for migrations.

Question 5

A customer is making a decision between Isilon and a competitor's offering. They currently have 100TB of usable capacity and are forecasting 100% growth per year for the next three years, which will require them to lease additional space in their co-located data center. The CFO finds ROI and TCO to be important decision criteria.

Which statement best emphasizes the value of Isilon for this customer?

AIsilon's OneFS data protection policies offer substantially lower overhead than competitive RAID based NAS solutions.

BAn IDC study found that Isilon requires 95% less down time hours per year compared to other competitors.

CThe competition cannot offer a scale-out NAS so as capacity is added to the array, performance may degrade.

DIsilon's OneFS allows administrators to manage much larger amounts of capacity than competitive offerings.

Answer : A

Question 6

Three jobs are running, all with a priority of 5. A new job with a priority of 6 needs to be run. What happens?

Question 7

A telecommunications company has a substantial amount of dat

a. 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.

Considering the customer's requirements, which is the best node type for the Isilon cluster?

ANL400 with 48GB RAM and no SSDs per node

BX400 with 96GB of RAM and no SSDs per node

CX400 with 24GB RAM and 1.6TB of SSD per node

DX200 with 24GB of RAM and 1.2TB of SSD per node

Answer : B
