Questions # 82:

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?

Options:

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


Expert Solution
Questions # 83:

A customer is able to see some performance metrics in the Isilon OneFS dashboard or by using CLI. Other performance metrics will require InsightIQ.

What will require a licensed version of InsightIQ?

Options:

A.

Capacity Trending


B.

Cluster Throughput


C.

CPU Usage


D.

Active Client Connections


Expert Solution
Questions # 84:

A customer has an SMB file directory with 375 TB of data on the primary cluster with a protection level of N+ 3:1. They want to replicate this directory to the secondary cluster. The customer would like information about the possibility of setting protection levels on the target cluster.

What information can be provided to the customer about the protection level for the target directory?

Options:

A.

Configured separately on the target cluster and does not need to match the source


B.

Configured separately on the target cluster and must match the source


C.

Controlled by SyncIQ and cannot be altered


D.

Controlled by SyncIQ and can be altered by the CLI


Expert Solution
Questions # 85:

By default, which method is used by Isilon OneFS for SSDs?

Options:

A.

Metadata read acceleration


B.

Metadata read/write acceleration


C.

Data on SSDs


D.

Avoid SSDs


Expert Solution
Questions # 86:

When installing nodes into a Dell EMC rack, which node type requires the use of a Titan-HD rack?

Options:

A.

H500


B.

F800


C.

A2000


D.

A200


Expert Solution
Questions # 87:

Independent of protocol, what does Isilon OneFS use to translate identities?

Options:

A.

ID mapping stack


B.

Role-based access control


C.

Access Zone


D.

SmartLock


Expert Solution
Questions # 88:

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?

Options:

A.

Change the protection scheme to a mirroring policy.


B.

Add A-Series performance accelerator nodes to the cluster.


C.

Add S-Series storage nodes to the cluster.


D.

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


Expert Solution

consume?

Options:

A.

85 KB


B.

128 KB


C.

160 KB


D.

192 KB


Expert Solution
