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 1
IPSLAs Latest Operation Statistics IPSLA operation id: 1 Type of operation: icmp-echo Latest RTT: 10 milliseconds Latest operation start time: 00:15:30 UTC Mon Mar 1 2021 Latest operation return code: OK Number of successes: 100 Number of failures: 0 Operation time to live: Forever
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 IP SLA operation is successful and has a low RTT.
The output shows an IP SLA operation of type icmp-echo with a return code 'OK', 100 successes, and 0 failures. This indicates the operation is functioning correctly.
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 failed 100 times.
Why it's wrong here
The output shows "Number of failures: 0" and "Number of successes: 100", so no failures occurred. Confusing the counters is tempting because both appear in the same statistics block, but a failed operation would instead show a non-OK return code and a rising failure count.
- ✓
The IP SLA operation is successful and has a low RTT.
Why this is correct
The output confirms 100 successes with zero failures, so the icmp-echo probe is completing reliably. A latest RTT of 10 milliseconds satisfies the low-latency expectation, and the OK return code verifies each operation finished within its configured timeout threshold.
- ✗
The IP SLA operation type is udp-jitter.
Why it's wrong here
The output explicitly states "Type of operation: icmp-echo", so the operation is ICMP echo, not UDP jitter. UDP jitter is tempting because it also uses IPSLA operation IDs and reports RTT statistics, and would be correct where the goal is measuring delay variation and packet loss for voice or video traffic.
- ✗
The IP SLA operation has expired.
Why it's wrong here
"Operation time to live: Forever" means the operation never expires, so it remains active indefinitely. Expiry is tempting because TTL appears in the output, but an expiring operation would display a finite lifetime value, and expiry would be relevant only when configuring a bounded schedule.
