A network engineer runs the following command to troubleshoot an IP SLA issue:
R1# debug ip sla monitor trace IP SLAs Monitor trace debugging is on *Mar 1 12:34:56.789: IP SLAs Monitor: Starting operation 10 *Mar 1 12:34:56.789: IP SLAs Monitor: Sending ICMP echo request to 192.168.1.1 *Mar 1 12:34:56.790: IP SLAs Monitor: Received ICMP echo reply from 192.168.1.1 *Mar 1 12:34:56.790: IP SLAs Monitor: RTT = 12 ms *Mar 1 12:34:56.790: IP SLAs Monitor: Operation 10 completed successfully *Mar 1 12:35:56.789: IP SLAs Monitor: Starting operation 10 *Mar 1 12:35:56.789: IP SLAs Monitor: Sending ICMP echo request to 192.168.1.1 *Mar 1 12:35:56.790: IP SLAs Monitor: Received ICMP echo reply from 192.168.1.1 *Mar 1 12:35:56.790: IP SLAs Monitor: RTT = 14 ms *Mar 1 12:35:56.790: IP SLAs Monitor: Operation 10 completed successfully
What does this output indicate?
⚠ Common exam trap
The trap is misreading normal RTT variation as degradation or failure — candidates must recognize that successful send/receive pairs with stable RTTs indicate a healthy probe, and that only missing replies or threshold breaches constitute failure.

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 monitor operation is successfully sending and receiving ICMP echo probes.
The debug output shows IP SLA operation 10 successfully sending ICMP echo requests to 192.168.1.1 and receiving echo replies, with round-trip times of 12 ms and 14 ms, and each operation completing successfully. This confirms the IP SLA probe is functioning correctly and the target is reachable. The slight RTT variation between probes is normal jitter, not a failure condition.
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 monitor operation is failing because the RTT values are increasing.
Why it's wrong here
Both probes returned replies with RTTs of 12 ms and 14 ms and completed successfully; a 2 ms variation is normal jitter, not failure. It is tempting because rising latency can indicate degradation, and it would be correct if RTTs breached the configured threshold or replies stopped arriving.
- ✓
The IP SLA monitor operation is successfully sending and receiving ICMP echo probes.
Why this is correct
Each cycle shows operation 10 sending an ICMP echo request to 192.168.1.1, receiving the echo reply, and reporting an RTT of 12–14 ms before completing successfully. That confirms the probe path is working, so the monitor is actively sending and receiving ICMP echoes as configured.
- ✗
The IP SLA monitor operation is not configured because no configuration is shown.
Why it's wrong here
The trace output shows operation 10 starting, sending ICMP echoes, receiving replies and completing successfully, which proves the operation exists and runs. It is tempting because the command displays no running-config lines, and it would be correct only if the debug showed no operation identifier or no probe activity at all.
- ✗
The IP SLA monitor operation is timing out because no reply is received.
Why it's wrong here
Every probe received an ICMP echo reply from 192.168.1.1 and reported completion, so no timeout occurred. It is tempting because timeouts are the usual IP SLA fault, and it would be correct if the trace showed requests sent with no reply and a timeout or threshold-exceeded message.
