350-401 Practice Question: Executes the following command on Router R8: R8#…
A network engineer executes the following command on Router R8:
R8# show ip sla monitor summary IP SLAs Monitor Summary
Codes: * active, ^ inactive, ~ pending
ID Type Destination Stats Return Code Last *1 icmp-echo 192.168.8.10 Success OK 1 ^2 udp-jitter 192.168.8.20 Success OK 2 *3 icmp-echo 192.168.8.30 Success OK 3
Based on this output, which IP SLA operations are currently active?
⚠ Common exam trap
Cisco often tests the legend interpretation in 'show ip sla monitor summary' output, where candidates may overlook the codes (*, ^, ~) and assume all listed operations are active, leading them to select 'All three operations' instead of correctly identifying only those marked with an asterisk.

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
✓
IDs 1 and 3
The output shows that IP SLA operations with IDs 1 and 3 are marked with an asterisk (*), which according to the legend indicates 'active' status. Operation ID 2 is marked with a caret (^), meaning it is 'inactive'. Therefore, only IDs 1 and 3 are currently active.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Only ID 1
Why it's wrong here
Choosing only ID 1 is incorrect because ID 3 also displays an asterisk (*) in the `show ip sla` output. The asterisk is Cisco's marker that an IP SLA operation is active and currently sending probes. Since both ID 1 and ID 3 show this marker, they both satisfy the active criterion, and a single-ID answer would ignore the equally active ID 3.
- ✗
Only ID 2
Why it's wrong here
ID 2 is marked with a caret (^), not an asterisk (*). In Cisco IOS IP SLA state indicators, the caret denotes that the operation is in an inactive or administratively shut down state, meaning it is not generating probe traffic. Therefore, selecting only ID 2 is doubly wrong: it picks the one operation that is not active, and it misses the two operations that actually show the active marker.
- ✓
IDs 1 and 3
Why this is correct
IDs 1 and 3 are the correct selection because both entries display an asterisk (*) in the `show ip sla` output, which indicates that each operation is active, scheduled, and currently sending synthetic probe traffic. The presence of * on both entries confirms they are the only operations meeting the active-status criterion. No other entries besides IDs 1 and 3 show this marker, making this the correct answer.
- ✗
All three operations
Why it's wrong here
Selecting all three operations is incorrect because ID 2 carries a caret (^) rather than an asterisk (*). While IDs 1 and 3 are active as shown by * , the caret on ID 2 indicates it is inactive or shut down, so it cannot be included in the set of active operations. An 'all three' answer would require every entry to show the active marker; since ID 2 does not, the complete active set is limited to IDs 1 and 3.
