A potential customer has 540TB Raw capacity of NetApp running in ONTAP 7-Mode. They
are willing to let you gather some workload data. Their authentication sources are LDAP
and Active Directory. Their users are primarily Windows Clients. They are very interested in
Automated Tiering and Large Scale Archives. They are not certain about the workflows
from the Marketing Department. The Content Team will only say they need to acquire 300
TB within 90 days. They do not know the average file size or the number of aggregates
they are managing.
Which tool(s) would you use next to complete your sizing?


A.

MiTrend WPA, Autosupport, and PerfCollect


B.

Isilon Cluster Sizing Tool


C.

Wireshark, isi statistics, and iostat


D.

Isilon Insight IQ, OnCommand Insight, and nfsstat





A.
  

MiTrend WPA, Autosupport, and PerfCollect



An Isilon customer has two 5-node clusters; one for production and one for disaster
recovery (DR). The customer's workflows are replicated to the DR cluster through SyncIQ
on individual schedules. They have shut down their production cluster for scheduled
maintenance, failed over to the DR cluster, and are currently operating from the DR site.
Assume both clusters have identical shares, exports, user authentication. In addition,
assume the client applications have been stopped and the DNS re-pointed. What is the
easiest SyncIQ Policy method to continue operations on production?


A.

Initiate Automated Failback


B.

Revert


C.

Initiate Manual Failback


D.

No change is needed

You have been invited to meet with the Social Media and Marketing Department and gather
requirements for a potential File System Project. They primarily use CIFS and are
considering deploying a Hadoop cluster to analyze customer demographic data. The
Senior Systems Engineer thinks they will need 2PB of usable capacity.
What would you do to gain an understanding of the customer’s environment to qualify and
develop the opportunity?


A.

Create a cluster configuration specifying HDFS, NFS, and CIFS protocols; select 19 x X400 nodes with 144TB per node, and Enhanced Support


B.

Request the Windows Systems Administration Team run a PerfMon analysis on the
Marketing Servers, consider adding 75 x 3TB drives to your VNX 5500, and contact the
DBA Team for their help


C.

Ask them to identify how the current data is accessed, where the data is accessed from,
and who is accessing the data


D.

Send the Social Media Team a sizing and features spreadsheet to complete; download the OneFS Architectural White Paper for them, and create a Logical System diagram in
Visio

You have had several discussions with your customer in the processor design industry.
They have stated that they want a Scale-Out NAS platform for their design environment.
Their most significant responses were "We have 125 design engineers accessing large
diagrams and we need high throughput to support them. Can we also get the highest
performance available? We need to stay ahead of our competitors." Other areas you
discussed were their data retention policies and workflow after the chip design is
completed. They plan to archive the design files but the files must stay on line.
What is your initial node recommendation?


A.

S-Series nodes for the active diagrams and NL Series nodes for the archives


B.

A-Series nodes for the active diagrams and X-Series nodes for the archives.


C.

X-Series nodes for the active diagrams and NL 400 nodes for the archives


D.

X-Series nodes with SSD for the active diagrams and NL nodes for the archives





A.
  

S-Series nodes for the active diagrams and NL Series nodes for the archives



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





A.
  

Configure SmartPools Advanced



A cost-conscious customer is exploring Isilon for their PACS archive. The workflow consists
of one hundred cases a day, each including fifty 60MB image files. However, each image
will have five-hundred 64kB metadata files associated with it. They currently have six years
worth of archived data. They will need to migrate to the new solution and they need to plan
for an additional three years of archive capacity.
Which solution would you recommend to fit their capacity needs?


A.

24 NL-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity


B.

18 NL-Series nodes with N+2:1 protection policy providing 2078 TiB of useable capacity


C.

24 X-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity


D.

12 NL-Series nodes with N+2 protection policy providing 1300 TiB of useable capacity





A.
  

24 NL-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity
