NetApp Certified Implementation Engineer – ONTAP v4 — Question 24

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

Which protocol is used for the discovery of controllers?

Answer options

• A. PXE
• B. LLDP
• C. TFTP
• D. mDNS

Correct answer: D

Explanation

The correct answer is mDNS, which is designed for service discovery on local networks, including automatic host discovery for NVMe/TCP. PXE, LLDP, and TFTP serve different purposes, such as booting over the network, link layer discovery, and file transfer, respectively, and are not suitable for this specific discovery process.
