CompTIA Network+ (N10-009) — Question 404

After a recent corporate merger, a network administrator needs to build reference documentation on multivendor infrastructure. Which of the following protocols will provide the information?

Answer options

• A. ICMP
• B. CDP
• C. LLDP
• D. SIP

Correct answer: C

Explanation

LLDP (Link Layer Discovery Protocol) is specifically designed to facilitate the discovery of devices in a multivendor network environment, allowing for detailed information about devices to be shared. CDP (Cisco Discovery Protocol) is limited to Cisco devices, while ICMP (Internet Control Message Protocol) and SIP (Session Initiation Protocol) do not provide the necessary device discovery capabilities.
