Introducing Cisco Data Center Networking (DCICN) — Question 68

Which two addresses represent multicast addresses? (Choose two.)

Answer options

• A. 224.1.47.5
• B. 240.100.22.3
• C. FF05::1
• D. 2001::1

Correct answer: A, C

Explanation

The correct answers are A and C because the address 224.1.47.5 falls within the IPv4 multicast range (224.0.0.0 to 239.255.255.255), and FF05::1 is an example of an IPv6 multicast address. Option B, 240.100.22.3, is not a valid multicast address as it is reserved for future use, and option D, 2001::1, is a unicast address.
