Discuss NetApp NS0-521 Exam Topic 9 Question 35

A storage administrator has just completed an ISCSI implementation in a customer environment running VMware and needs to validate that the entire network path supports jumbo frames.

Which action should be taken?

APing from the host with fragmentation.

BCheck the VMkernel adapter settings.

CPing from the host without fragmentation.

DCheck the broadcast domain settings.

Suggested Answer: A

To validate that the entire network path supports jumbo frames after an iSCSI implementation, you should perform a ping test from the host with fragmentation. This involves using the ping command with specific options to test jumbo frame support:

ping -M do -s 8972 <target_IP>

In this command:

-M do ensures the packets are not fragmented.

-s 8972 sets the packet size to 8972 bytes (9000 bytes MTU minus 28 bytes for the ICMP header).

By confirming that the large packets are successfully transmitted without fragmentation, you can validate that the network path, including switches and adapters, supports jumbo frames.

Definitely B and C together. You need to ensure both settings are correct.

I’m leaning towards option C as well. It’s straightforward and effective.

Myra 1 month ago

I feel like option D is important too. Broadcast domain settings can affect performance.

Teri 2 months ago

Option A seems risky. Fragmentation can lead to misleading results.

Dominga 2 months ago

I agree, but checking the VMkernel adapter settings (option B) is also crucial.

Arlene 2 months ago

I think option C is the best choice. No fragmentation means we can test jumbo frames directly.

Alesia 2 months ago

All options have merit, but I think B and C together cover all bases.

Tomas 2 months ago

I’m leaning towards option C. It’s straightforward and effective for validation.

Option D might be overlooked, but checking the broadcast domain is crucial for jumbo frames.

Flo 3 months ago

I feel like option A could be useful too. It shows how the network handles larger packets.

Rossana 3 months ago

I agree, but option B is also important. We need to ensure the VMkernel settings are correct.

Tiffiny 3 months ago

I think option C is the best choice. No fragmentation means we can test jumbo frames directly.

Loreta 3 months ago

Not sure if this is enough to confirm everything's set up right.

Rolf 3 months ago

Wait, can you really validate jumbo frames just by pinging?

Julianna 4 months ago

Agree, option C makes the most sense for testing jumbo frames.

Marylou 5 months ago

I think pinging without fragmentation is the way to go.

Callie 5 months ago

Definitely check the VMkernel adapter settings first.

Bettina 6 months ago

I feel like checking the broadcast domain settings could also be relevant, but I can't recall if it's directly related to jumbo frames validation.

Sean 6 months ago

I'm a bit confused about the fragmentation part. Should we really be pinging with fragmentation to test jumbo frames?

Katie 6 months ago

I remember practicing a question similar to this, and I think pinging from the host without fragmentation could help confirm jumbo frames support.

Isadora 6 months ago

I think checking the VMkernel adapter settings might be important, but I'm not entirely sure if that's the best first step.
