Nokia Certified Network Associate (NCNA) — Question 54

Which of the following type of addressing scheme delivers information from one source to all devices who are members of a specific group?

Answer options

• A. Anycast.
• B. Multicast.
• C. Broadcast.
• D. Unicast.

Correct answer: B

Explanation

The correct answer is Multicast, as it specifically allows for the transmission of data to multiple recipients who are part of the same group, optimizing network traffic. Anycast sends data to the nearest member of a group but not everyone, Broadcast sends data to all devices on the network, and Unicast is a one-to-one communication method.
