Question # 33

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?

Configure the switch ports for LACP and use LACP aggregation for subnet0:pool0.

Configure the switch ports as access points and use LACP aggregation for subnet0:pool0.

Configure the switch ports for LACP and use FEC aggregation for subnet0:pool0.

Configure the switch ports as access points, bond ext-0 and ext-1 on all nodes and use Active/Passive aggregation for subnet0:pool0.

Question # 35

A potential customer requires 800 TB of usable capacity to store medical images for their network of health clinics. The IT department has limited staff and currently manages four storage arrays from other vendors. During a meeting with the Director of IT you learn that the company is considering a solution from a competitor of EMC using two of the existing arrays and two new arrays.

Which Isilon capabilities would show a better ROI for the customer?

Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions.With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is typically 80% or higher.Isilon utilization is typically 80% or higher due to use of a single filesystem and virtual capacity for drive and node failures.

With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is typically 80% or higher.OneFS compression results in higher effective capacity within the cluster.Traditional clustered filesystems require 4%-10% internal overhead compared to Isilon virtual capacity.

Forward Error Correction overhead is 7% lower than traditional RAID.Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions.According to an IDC study, Isilon improves IT productivity by nearly 50% compared to traditional competitors.

Isilon has 15%-20% less overhead than traditional clustered filesystems.According to an IDC study, Isilon utilization is nearly 50% higher than traditional competitors.Isilon QOS headroom and multiple node pools ensures consistent performance up to 80% utilization.

Question # 37

A NetApp customer is considering Isilon. They use their filers for UNIX home directories, and would like to see a suggested configuration that would meet their needs.

What would you do to help size this cluster?

Ask for an autosupport file and upload it to MiTrends to generate a workflow profile

Ask them to install InsightIQ and collect data from the filer, then import to SQL for analysis

Ask for the output from nfsstat and upload it to MiTrends to generate a workflow profile

Use tcpdump and upload the output file to MiTrends to generate a protocol analysis

Question # 39

A customer is planning an Isilon deployment for use with their Hadoop environment. What is one advantage of using Isilon as the HDFS layer?

Facilitates independent scaling of compute and storage nodes

Provides single protocol access to data

Integrates storage into Hadoop compute for more flexibility

Allows the compute nodes to apply data protection

Question # 40

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 been reviewing their disaster recovery plan and found the following:

The policies specify that SyncIQ runs a replication job every 2 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

What is the Recovery Point Objective in this plan?

2 Hours

3 Hours

4 Hours

5 hours
