HPE Aruba Certified Network Security Expert (ACNSX) — Question 21

Which protocol does NetEdit use to discover devices in a subnet during the discovery process?

Answer options

• A. LLDP
• B. ARP
• C. DHCP
• D. ICMP

Correct answer: A

Explanation

LLDP (Link Layer Discovery Protocol) is the correct answer because it allows network devices to advertise their identity and capabilities on a local area network. The other options, ARP (Address Resolution Protocol), DHCP (Dynamic Host Configuration Protocol), and ICMP (Internet Control Message Protocol), serve different purposes and are not specifically used by NetEdit for device discovery.
