A network engineer runs the following command on Router R1:

R1# show ip sla statistics 6

Round Trip Time (RTT) for Index 6 Latest RTT: 0 ms Latest RTT (milliseconds): 0 Latest RTT (microseconds): 0 Number of successes: 0 Number of failures: 100 Operation time to live: Forever Output: No connection

R1# show track 4
Track 4
  IP SLA 6 reachability

Reachability is Down 3 changes, last change 00:05:00 Latest operation return code: No connection Latest RTT (milliseconds): 0

Tracked by:
    ip route 0.0.0.0 0.0.0.0 192.168.4.1 track 4

R1# show ip route 0.0.0.0 0.0.0.0

% Network not in table

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 target 192.168.4.1 is unreachable, causing the IP SLA to fail and the static route to be removed.

The track is down due to 'No connection', and the static route is not in the routing table. This indicates that the IP SLA probe cannot reach the target, and the tracked route has been removed.

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 still present because the track is down.

    Why it's wrong here

    When the track goes down, the static route is removed from the routing table.

  • ✗

    The IP SLA operation is successful, but the track is misconfigured.

    Why it's wrong here

    The IP SLA shows 'No connection', so it is not successful.

  • ✓

    The target 192.168.4.1 is unreachable, causing the IP SLA to fail and the static route to be removed.

    Why this is correct

    The 'No connection' indicates unreachability, and the track down removes the static route.

  • ✗

    The IP SLA operation has a threshold violation, but the route is still active.

    Why it's wrong here

    The return code is 'No connection', not 'Over threshold', and the route is not active.

Variation 1. 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 0.0.0.0 Routing 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?

medium
  • A.The static route is not installed because the track is up.
  • B.The IP SLA operation is failing, causing the track to go down.
  • ✓ C.The static route is active and reachable via 192.168.3.1.
  • D.The IP SLA operation has a threshold violation.

Why C: 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.
