Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Hello Timer: 5 seconds
EIGRP timers and their defaults: Hello timer defaults to 5 seconds on LAN interfaces; Hold timer defaults to 15 seconds (3 times Hello). Active timer defaults to 3 minutes. Retransmission timer defaults to 0.5 seconds. There is no standard 'Update Timer' with a default of 5 seconds; the correct timer for 5 seconds is Hello, not Update.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Hello Timer: 5 seconds
Why this is correct
Correct: Hello timer default is 5 seconds on LAN.
Hold Timer: 15 seconds
Why this is correct
Correct: Hold timer default is 15 seconds (3x Hello).
Active Timer: 3 minutes
Why this is correct
Correct: Active timer default is 3 minutes.
Update Timer: 5 seconds
Why it's wrong here
Incorrect: EIGRP does not have a standard 'Update Timer' with a default of 5 seconds. The 5-second default belongs to the Hello timer.
Retransmission Timer: 0.5 seconds
Why this is correct
Correct: Retransmission timer default is 0.5 seconds.
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.
