The correct answer is that all EIGRP neighbors are operating normally, as the output shows no signs of instability or failure. This conclusion is drawn from the key fields in the show ip eigrp neighbors output: a Q count of 0 for each neighbor indicates no packets are queued for retransmission, while low SRTT and RTO values (10–15 ms and 200 ms, respectively) reflect stable, low-latency links. Additionally, the hold timers are all well below the default 15-second maximum, and the uptimes show sustained adjacency without flapping. On the Cisco CCNP ENARSI 300-410 exam, this command tests your ability to quickly assess neighbor health and identify issues like stuck-in-active or packet loss. A common trap is misreading the Hold column—it shows remaining seconds, not the configured hold time, so values near zero indicate a problem, not normal operation. Remember the memory tip: “Q zero, SRTT low, hold not zero—neighbor’s a hero.”
300-410 Device Management Practice Question
This 300-410 practice question tests your understanding of device management. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network engineer runs the following command on Router R1:
R1# show ip eigrp neighbors
IP-EIGRP neighbors for process 100
H Address Interface Hold Uptime SRTT RTO Q Seq
(sec) (ms) Cnt Num
0 192.168.1.2 Gi0/0 13 00:12:34 10 200 0 15

2 10.10.10.2 Gi0/2 14 00:08:15 15 200 0 18
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
All EIGRP neighbors are operating normally.
The output shows three EIGRP neighbors with normal hold timers and uptimes. The Q count is 0 for all, indicating no queued packets. The SRTT and RTO values are low, indicating good network conditions. There is no problem evident in this output.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Neighbor 192.168.1.2 has a high SRTT indicating a slow link.
Why it's wrong here
SRTT of 10 ms is low, not high.
✓
All EIGRP neighbors are operating normally.
Why this is correct
All neighbors show normal hold timers, uptimes, and zero queued packets.
Neighbor 10.10.10.2 is experiencing packet loss due to high RTO.
Why it's wrong here
RTO of 200 ms is standard for this SRTT.
✗
The Q count of 0 indicates that EIGRP is not exchanging routes.
Why it's wrong here
Q count of 0 means no packets are queued, which is normal.
Common exam traps
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
OSPF neighbours must agree on key parameters.
Router ID selection can affect neighbour relationships and LSDB output.
OSPF cost influences the preferred path.
A route can appear in OSPF information but not become the installed route.
TExam Day Tips
→Check area mismatch first when OSPF adjacency fails.
→Review passive interfaces when a network is advertised but no neighbour forms.
→Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Real-world example
How this comes up in practice
A network engineer at a university connects two campus buildings via a fibre link. Both routers run OSPF, but no adjacency forms — even though both routers can ping each other. The engineer finds one router is in area 0 and the other in area 1. OSPF adjacency requires matching area numbers, hello/dead timers, and network type. IP reachability alone is not enough.
