300-410 Practice Question: Which EIGRP packet type is used to confirm…
Which EIGRP packet type is used to confirm receipt of a route update during reliable transport?
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
✓
ACK
EIGRP uses ACK packets (which are Hello packets with no data) to acknowledge reliable updates.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Hello
Why it's wrong here
Hello packets are used for neighbor discovery and keepalive, not specifically for acknowledgments.
- ✗
Update
Why it's wrong here
Update packets carry routing information and require acknowledgment.
- ✓
ACK
Why this is correct
ACK packets are Hello packets with no data, used to acknowledge received updates.
- ✗
Query
Why it's wrong here
Query packets are used during route recomputation, not for acknowledgments.
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.
