ICND1: Interconnecting Cisco Networking Devices Part 1 (CCENT, legacy) — Question 47

Which IPv4 address type is used to communicate with all hosts on a subnet?

Answer options

• A. broadcast
• B. link-local
• C. anycast
• D. multicast

Correct answer: D

Explanation

The correct answer is D, multicast, as it is specifically designed to allow communication with multiple hosts on a subnet. Option A, broadcast, targets all devices in a network segment but is not the focus here. Link-local (Option B) is used for communication within a single network segment and is not for addressing all hosts, while anycast (Option C) is meant for routing packets to the nearest instance of a service rather than all hosts.
