Drag and drop each CoPP class on the left to its matching traffic type on the right.
Drag a concept onto its matching description — or click a concept then click the description.
Protects routing protocol packets like OSPF, BGP, EIGRP
Permits management traffic such as SSH, SNMP, and Telnet
Handles packets requiring CPU intervention (e.g., TTL expired, unreachable)
Matches any traffic not explicitly classified by other classes
Reserved for high-priority control plane traffic (e.g., LDP, RSVP)

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Routing class: Protects routing protocol packets like OSPF, BGP, EIGRP
Routing class protects control plane routing protocols; Management class allows SSH/SNMP; Exception class handles packets that need CPU processing (e.g., TTL expiry); Default class matches all other traffic; Critical class is for high-priority control traffic.
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.
