A network engineer runs the following command to troubleshoot an IP SLA issue:
R1# show ip sla statistics 10 detail
Round Trip Time (RTT) for Index 10 Latest RTT: 12 ms Latest RTT (milliseconds): 12 Latest RTT (microseconds): 12000 Last operation start time: 12:34:56.789 UTC Mon Mar 1 2021 Last operation return code: OK Number of successes: 100 Number of failures: 0 Operation time to live: Forever Last operation response time: 12 ms Latest operation start time: 12:34:56.789 UTC Mon Mar 1 2021 Latest operation return code: OK Over thresholds occurred: FALSE Threshold (milliseconds): 5000 RTT Values: RTTAvg: 12 RTTMin: 10 RTTMax: 15 RTTNum: 100 RTTStdDev: 1
What does this output indicate?
⚠ Common exam trap
The trap is misinterpreting the statistics: candidates might think that a low standard deviation indicates high jitter, or that any RTT above a certain value is a threshold violation, but the threshold is explicitly given as 5000 ms.
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 IP SLA operation shows stable performance with low jitter and no threshold violations.
The output shows stable performance with low jitter (standard deviation of 1 ms) and no threshold violations (over thresholds occurred: FALSE, threshold is 5000 ms). The number of failures is 0, indicating no packet loss.
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 has high jitter because the RTT standard deviation is 1 ms.
Why it's wrong here
A standard deviation of 1 ms against a 12 ms average indicates stable, low-variance round-trip times, not high jitter. The option is tempting because jitter is derived from RTT variation, so a standard deviation figure looks relevant, but 1 ms is negligible here; the output actually reports a healthy operation with zero failures and no threshold breaches.
- ✗
The IP SLA operation is experiencing packet loss because the number of failures is 0.
Why it's wrong here
Zero failures alongside 100 successes indicates no packet loss, so the operation is healthy. The failures counter is what would reveal loss; here it is empty. This output is what an engineer expects when validating that an SLA probe meets its threshold, not when diagnosing drops.
- ✓
The IP SLA operation shows stable performance with low jitter and no threshold violations.
Why this is correct
Latest RTT of 12 ms against a 5000 ms threshold, zero failures across 100 successes, and RTTStdDev of 1 ms with a 10-15 ms range show consistent latency and minimal jitter, so no threshold breach has occurred.
- ✗
The IP SLA operation has exceeded the threshold because the RTTMax is 15 ms.
Why it's wrong here
The threshold is 5000 ms and RTTMax is 15 ms, far below it; the output even states 'Over thresholds occurred: FALSE'. Threshold monitoring is the right mechanism when RTT approaches the configured limit, but this operation is comfortably within bounds.

IP SLA for Path Control
IP SLA for Path Control is a Cisco technology that uses active network measurements to dynamically influence routing decisions and redirect traffic along a preferred path when network conditions change.
