Latest updates EMC E20-555 exam practice questions (1-10)

QUESTION 1
An Isilon has two ports configured per node. Each port is on a different VLAN. Although incoming traffic is evenly
distributed, transmitted data from the Isilon uses one port more than the other port. What could be the cause of this
imbalance?
A. Static routes are configured on the less-used port
B. A default gateway was not configured on both ports

QUESTION 3
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.

solutions.
B. An IDC study found that Isilon requires 95% less down time hours per year compared to other competitors.
C. The competition cannot offer a scale-out NAS so as capacity is added to the array, performance may degrade.
D. Isilon\\’s OneFS allows administrators to manage much larger amounts of capacity than competitive offerings.
Correct Answer: A

QUESTION 4

A customer wants to use their large Gen 6 Isilon cluster for ILM. All of their data is written to and read from a single file
pool. They need to use multiple file pools, so slightly used data is stored on less expensive, large disks. Heavily used
data is stored on a faster tier.
What would satisfy the customer\\’s needs?
A. Configure SmartPools Advanced
B. Add an A-series node with SmartPools license
C. Enable FAST VP license on each node pair
D. Install SmartPools license on the cluster

QUESTION 10
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
Correct Answer: C
