A network engineer runs the following command on Router R1:
R1# show ip sla statistics 5
Round Trip Time (RTT) for Index 5 Latest RTT: 50 ms Latest RTT (milliseconds): 50 Latest RTT (microseconds): 50000 Number of successes: 100 Number of failures: 0 Operation time to live: Forever Output: OK
R1# show track 3 Track 3 IP SLA 5 reachability
Reachability is Up 1 change, last change 00:10:00 Latest operation return code: OK Latest RTT (milliseconds): 50
Tracked by:
ip route 0.0.0.0 0.0.0.0 192.168.3.1 track 3
R1# show ip route 0.0.0.0 0.0.0.0Routing entry for 0.0.0.0/0, supernet Known via "static", distance 1, metric 0, candidate default path Last update from 192.168.3.1 on GigabitEthernet0/0 Routing Descriptor Blocks:
* 192.168.3.1, via GigabitEthernet0/0
Route metric is 0, traffic share count is 1
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 static route is active and reachable via 192.168.3.1.
The track is up, and the static route is present in the routing table. The IP SLA has 100% success. This indicates everything is working 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 static route is not installed because the track is up.
Why it's wrong here
The track is up, so the static route is installed and present in the routing table as the candidate default. It tempts because tracking can remove a route when the object goes down, but here reachability is Up with return code OK, so the route remains active.
- ✗
The IP SLA operation is failing, causing the track to go down.
Why it's wrong here
The IP SLA statistics show 100 successes, 0 failures and return code OK, so the operation is succeeding and the track is Up. It tempts because failed SLA operations do bring tracks down, but the counters here show no failures at all.
- ✓
The static route is active and reachable via 192.168.3.1.
Why this is correct
Track 3 reports reachability Up with return code OK, and the default static route via 192.168.3.1 is installed in the routing table as the candidate default path. This satisfies the stem's requirement that the tracked route is both active and reachable.
- ✗
The IP SLA operation has a threshold violation.
Why it's wrong here
No threshold violation appears: the return code is OK and the track reports reachability Up. It tempts because SLA operations can be configured with thresholds that mark a track down, but this output shows no threshold breach and no down state.
