A potential customer has about 540TB of NetApp running in ONTAP 7-Mode. They are willing to let you gather some workload data. They have LDAP and Active Directory authentication and 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 tools would you use to gather information to do your Isilon sizing?

1. A. MiTrend WPA, Autosupport, and PerfCollect
2. B. isi status, isi_netlogger, and PerfMon
3. C. Wireshark, isi statistics, and iostat
4. D. Isilon Insight IQ, OnCommand Insight, and nfsstat

Correct Answer: A

Refer to the exhibit.

You want to add redundancy to your network configuration, rather than performance. You have configured all interfaces into the default SmartConnect zone.
How should you configure the switches and Isilon networking to provide your desired network redundancy?

1. A. Configure the switch ports for LACP and use LACP aggregation for subnet0:pool0.
2. B. Configure the switch ports as access points and use LACP aggregation for subnet0:pool0.
3. C. Configure the switch ports for LACP and use FEC aggregation for subnet0:pool0.
4. D. Configure the switch ports as access points, bond ext-0 and ext-1 on all nodes and use Active/Passive aggregation for subnet0:pool0.

Correct Answer: A

Which type of deduplication is used to maximize the storage efficiently on an Isilon cluster?

1. A. Fixed-segment
2. B. Post-process
3. C. Target-based
4. D. Inline

Correct Answer: B

A customer has two data centers (Site A and Site B).There is an Isilon cluster in each data center and they use SyncIQ to replicate data between the two data centers.
You have reviewed their disaster recovery plan and found the following:
The policies specify that SyncIQ runs a replication job every 3 hours and that the job finishes within 1 hour.
Three additional hours will be needed to get servers and the network redirected to work from Site B.
What is the Recovery Point Objective in this plan?

1. A. 2 Hours
2. B. 3 Hours
3. C. 4 Hours
4. D. 5 Hours

Correct Answer: C

Your customer is looking for a storage solution that will be able to store seven million 3 MB files, which are written and seldom accessed. Read and write operations are both completed by a web-based application, which requires 1.3 Gbps throughput. The customer's network has not been upgraded in many years, so the network interfaces are 1Gbps.
Which cluster configuration would best meet the customer's requirements?

1. A. 3 NL400 nodes
2. B. 3 X400 nodes
3. C. 4 X200 nodes
4. D. 5 S200 nodes

Correct Answer: D
