Correct answer & explanation
224.0.0.0/24: Link-local multicast (e.g., OSPF, EIGRP, PIM hello)
224.0.0.0/24 is reserved for link-local multicast (e.g., routing protocols); 232.0.0.0/8 is for SSM; 239.0.0.0/8 is for administratively scoped (private) multicast; 224.0.1.0–238.255.255.255 is for global unicast-based multicast; 224.0.0.0/4 is the overall multicast range.
Quick reference
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Drag and drop each multicast address range on the left to its matching use on the right.
mediumWhy P1: 224.0.0.0/24 is reserved for link-local multicast; 232.0.0.0/8 is for Source-Specific Multicast; 239.0.0.0/8 is for administratively scoped (private) multicast.
