NetApp NS0-521 Exam - Topic 4 Question 9 Discussion

Actual exam question for NetApp's NS0-521 exam

Question #: 9
Topic #: 4

A customer Is setting up a four-node NetApp AFF cluster for use with NVMe/TCP and wants to use automatic host discovery.

Which protocol is used for the discovery of controllers?

ATFTP

BmDNS

CLLDP

DPXE

Show Suggested Answer

Suggested Answer: B

For automatic host discovery in a four-node NetApp AFF cluster using NVMe/TCP, the protocol used is mDNS (Multicast DNS). mDNS allows for the discovery of controllers and other networked devices without the need for a centralized DNS server, simplifying the setup process in environments that support NVMe over TCP.

PXE? That's a surprise, I didn't expect that option here!

LLDP is the right one, no doubt about it!

I thought it was mDNS? Seems like a common choice.

It's definitely LLDP for controller discovery.

I feel like PXE is more about booting over the network, so it probably isn’t the right choice here.

I’m a bit confused; I thought TFTP was related to file transfers, not discovery.

I remember practicing a similar question, and I think LLDP was mentioned as a discovery protocol.

PXE is an interesting option, but I don't think it's the right protocol for discovering NetApp controllers specifically. I'll go with mDNS.

I'm leaning towards TFTP, as that's often used for booting and configuring network devices, but I'm not 100% confident.

Hmm, TFTP? More like 'Too Far To Ponder' amirite? Clearly mDNS is the way to go.

mDNS, the answer's gotta be mDNS. What is this, a trick question?
