Hi!

I am going through this training, preparing for the exam.

In the study material (Module 2 - Resource 1 - Isilon Sizing Considerations - Page 24) it states:

[...]If they need more than 600 MB per second, an A100 node is the only way we provide it.[...]

In the practice exam there's a question that says:

A customer wants to replace a legacy storage environment used for high definition video editing. Each workstation connecting to the shared storage needs to sustain 650 MB/s of single stream bandwidth.

Which node type is recommended?

NL-Series nodes

S-Series nodes

X-Series nodes

Performance Accelerator nodes

But when I select "Performance Accelerator Node" It will mark my question as wrong:

1.

A customer wants to replace a legacy storage environment used for high definition video editing. Each workstation connecting to the shared storage needs to sustain 650 MB/s of single stream bandwidth.

Which node type is recommended?

Explanation

Topic: Describe EMC Isilon scaled-out storage platform opportunities. For example, describe Big Data and the associated workloads, Isilon considerations and/or characteristics, scale-out NAS architecture and storage node considerations

Training: Isilon Infrastructure Solutions Course - Module 1, Isilon Foundations Course - Modules 1 and 3

Am I getting it all wrong? Or is it that the answer is wrong? I would really appreciate your help

Thanks!!
