300-410 Practice Question: Runs the following command on Router R1: R1# show…
A network engineer runs the following command on Router R1:
R1# show ip sla statistics 2
Round Trip Time (RTT) for Index 2 Latest RTT: No connection Latest RTT (milliseconds): No connection Latest RTT (microseconds): No connection Number of successes: 0 Number of failures: 100 Operation time to live: Forever Output: No connection
Based on this output, which statement is correct?
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
✓
The target device is not responding to ICMP echo requests, or there is a routing problem.
The output shows 'No connection' for RTT and 'Output: No connection'. This indicates that the IP SLA operation cannot reach the target. The 100 failures confirm this. This is a clear sign of a connectivity issue.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The IP SLA operation is working correctly but the RTT is too high to measure.
Why it's wrong here
Zero successes with 100 failures and "No connection" means the probe never reached its target, so no RTT exists to measure. High latency would still return numeric RTT values. IP SLA statistics like these are used to verify reachability for tracking objects; a correctly functioning operation against a responsive target would show successes and populated RTT figures.
- ✓
The target device is not responding to ICMP echo requests, or there is a routing problem.
Why this is correct
Zero successes against 100 failures, with "No connection" reported, means no probe ever completed. The target is either not answering ICMP echo requests or is unreachable due to a routing fault, matching the stated symptom exactly.
- ✗
The IP SLA operation has been manually disabled.
Why it's wrong here
The output shows 100 failures with "No connection", meaning the probe ran but received no reply — not that it was disabled. A disabled operation reports no statistics at all. Manual disabling is the right diagnosis when an operation must be paused for maintenance without deleting its configuration.
- ✗
The IP SLA responder is misconfigured on the source router.
Why it's wrong here
A responder is configured on the destination device, not the source router, so this misdiagnoses the failure. The output shows 100 failures with no successes, indicating the probe never reached a listening responder. Configuring a responder on the source is tempting because it is required for some operations, but only when that router is the probe's target.
