Question 1mediumdrag order
Full question →Question 1,432 of 2,152
Quick Answer
The correct order for troubleshooting IP SLA connectivity failures ends with adjusting threshold or timeout parameters, as this step should only be taken after all foundational checks have been completed. This sequence is critical because IP SLA relies on consistent probe responses to measure network performance; prematurely tuning thresholds can mask underlying issues like routing problems or ACL blocks. On the Cisco CCNP ENARSI 300-410 exam, this drag-and-drop task tests your ability to apply a logical, layered troubleshooting methodology—starting with verifying the IP SLA operation state, then confirming reachability via extended ping, inspecting the configuration, reviewing access lists or routing, and only finally fine-tuning thresholds or timeouts. A common trap is jumping to parameter adjustments when the real fault is a missing source-interface or a denied probe packet. To remember the order, think of the mnemonic "S-C-I-R-A": State, Connectivity, Inspection, Routing, Adjust.
300-410 IP SLA Practice Question
This 300-410 practice question tests your understanding of ip sla. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Drag and drop the steps to troubleshoot IP SLA adjacency or connectivity failures into the correct order, from first to last.

Correct answer & explanation
✓
Verify IP SLA operation state with 'show ip sla statistics'
Start by verifying the IP SLA operation state to see if it is active or failed, then check reachability to the target using extended ping with the same source, inspect the IP SLA configuration for errors, review access lists or routing that may block probes, and finally adjust parameters like threshold or timeout as needed.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
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.
What to study next
Got this wrong? Here's your next step.
Review OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related 300-410 OSPF questions on adjacency and route selection.
