CCNP Practice Question: Which two statements about EIGRP feasible…
Which two statements about EIGRP feasible successors are true? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A feasible successor must have a reported distance less than the feasible distance.
A feasible successor is a backup route that meets the feasibility condition (reported distance < feasible distance). It is stored in the topology table and can be used immediately if the successor fails, without querying neighbors. The feasible distance is the lowest metric to a destination; the successor is the route with that metric. The reported distance is the neighbor's metric to the destination.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A feasible successor must have a reported distance less than the feasible distance.
Why this is correct
Correct because the feasibility condition requires the reported distance (neighbor's metric) to be strictly less than the feasible distance (the current best metric).
- ✓
A feasible successor is immediately used when the successor fails, without any query process.
Why this is correct
Correct because EIGRP can instantly switch to a feasible successor because it is guaranteed to be loop-free.
- ✗
The feasible distance is the metric of the feasible successor route.
Why it's wrong here
Incorrect because the feasible distance is the metric of the successor (best) route, not the feasible successor.
- ✗
EIGRP will always have at least one feasible successor for every route.
Why it's wrong here
Incorrect because feasible successors are not guaranteed; they depend on the network topology and the feasibility condition.
- ✗
The feasible successor is stored in the routing table as a backup route.
Why it's wrong here
Incorrect because feasible successors are stored in the topology table, not the routing table. Only the successor is placed in the routing table.
Quick reference
Routing Protocol Comparison
| 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.
