A network engineer runs the following command on Router R1:
R1# show ip sla statistics
IPSLAs Latest Operation Statistics
IPSLA operation id: 1 Type of operation: icmp-echo Latest RTT: 20 milliseconds Latest operation start time: 12:00:00 UTC Mon Mar 1 2021 Latest operation return code: OK Number of successes: 100 Number of failures: 0
Based on this output, which statement is correct?
⚠ Common exam trap
Cisco often tests the ability to interpret the 'Number of successes' and 'Number of failures' fields correctly, where candidates may mistakenly associate the count with failures instead of successes, or confuse the operation type (ICMP echo vs. UDP jitter) based on the operation ID alone.
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 probe is successfully reaching the target with no failures.
The output shows 100 successes and 0 failures for the ICMP echo operation, with a latest return code of OK, confirming that the IP SLA probe is successfully reaching the target without any failures. The 'Number of successes: 100' and 'Number of failures: 0' directly indicate a 100% success rate for the probe.
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 probe is successfully reaching the target with no failures.
Why this is correct
The return code OK, 100 successes and zero failures confirm the icmp-echo probe reaches its target successfully. Latest RTT of 20 milliseconds shows reachability with measurable latency, directly satisfying the scenario's requirement to verify probe success.
- ✗
The IP SLA probe has failed 100 times.
Why it's wrong here
The output shows Number of successes: 100 and Number of failures: 0, so the probe succeeded 100 times. Reading 'successes' as failures inverts the counters. The failures field is what would indicate probe loss, and here it reads zero.
- ✗
The IP SLA probe is using UDP jitter.
Why it's wrong here
Type of operation: icmp-echo identifies an ICMP echo probe, not UDP jitter. UDP jitter operations appear with that type label and report jitter and latency statistics. ICMP echo suits reachability and round-trip measurement, which is exactly what this output shows.
- ✗
The IP SLA probe is not configured because the operation ID is 1.
Why it's wrong here
Operation ID 1 is a valid, active identifier; the statistics confirm 100 successful probes. IDs are assigned sequentially and carry no disabled meaning. A configured operation is precisely what produces this output, so the ID value proves configuration rather than absence.
