Huawei Certified Network Professional – Routing and Switching (HCNP-RS, legacy) — Question 12

Which of the following is the address range assigned by IANA for SSM service in IPv4?

Answer options

• A. 232.0.0.0/24
• B. 225.0.0.0/8
• C. 232.0.0.0/8
• D. 239.0.0.0/8

Correct answer: D

Explanation

The correct answer is D, 239.0.0.0/8, which is specifically allocated for Source-Specific Multicast (SSM) in IPv4. Options A and C are incorrect as they represent different ranges that do not pertain to SSM, while option B is a broader multicast range that also does not correspond to SSM services.
