NetApp NS0-521 Exam - Topic 4 Question 9 Discussion

Actual exam question for NetApp's NS0-521 exam
Question #: 9
Topic #: 4
[All NS0-521 Questions]

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?

Show Suggested Answer Hide 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.

For further information, refer to:

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

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.

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.
