Exam N10-009 Topic 1 Question 142 Discussion

Actual exam question for CompTIA's N10-009 exam
Question #: 142
Topic #: 1
A company implements a video streaming solution that will play on all computers that have joined a particular group, but router ACLs are blocking the traffic. Which of the following is the most appropriate IP address that will be allowed in the ACL?

Suggested Answer: C Vote an answer

224.0.0.1 is a multicast address that allows packets to be sent to all hosts within a multicast group. Since video streaming often uses multicast to efficiently distribute data to multiple clients without unnecessary duplication, this is the correct answer.
*Why not the other options?
*127.0.0.1 (A) - This is the loopback address used for internal device testing, not for multicast traffic.
*172.17.1.1 (B) - This is a private unicast address, meaning it can only send packets to one specific host.
*240.0.0.1 (D) - This falls within the reserved experimental IP address range and is not used for multicast.
