300-410 Practice Question: Configured IP SLA 70 to monitor a remote site's…
A network engineer configured IP SLA 70 to monitor a remote site's LAN gateway (172.16.1.1) using ICMP echo. The IP SLA is linked to a track object that is used in a static route for a backup link. The engineer notices that the IP SLA state is 'Active', but the backup static route is installed in the routing table even when the primary route is available. What is the most likely cause?
⚠ Common exam trap
300-410 often tests whether candidates realize that configuring IP SLA and a track object alone does nothing unless the static route explicitly references the track with the 'track' keyword.
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 configured without the 'track' keyword, so it is always installed regardless of the IP SLA state.
If the static route is configured without the 'track' keyword, the track object has no effect on that route — the route is installed unconditionally whenever its administrative distance is lower than competing routes. The IP SLA being 'Active' only confirms the probe is running, not that the route is bound to it. The most likely cause is that the track was never attached to the static route statement.
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 configured without the 'track' keyword, so it is always installed regardless of the IP SLA state.
Why this is correct
Without the 'track' keyword binding the static route to the track object, the route is installed unconditionally; the IP SLA and track state are never consulted, so the backup route remains present even when the primary path is up.
- ✗
The IP SLA probe is failing intermittently, causing the track object to flap.
Why it's wrong here
Intermittent probe failure would make the track object flap, removing and reinstalling the route repeatedly, not leave the backup route permanently installed while the primary is available. Flapping is tempting because IP SLA failures do affect tracking, but the steady symptom indicates a misconfigured track or route preference instead.
- ✗
The primary route has a higher administrative distance than the static route.
Why it's wrong here
Administrative distance governs selection between protocols, not whether a tracked static route is installed; the backup route appears because the track object reports up. It is tempting because AD does decide route preference, but here the primary and backup are both statics.
- ✗
The track object is configured with a delay that causes the static route to be installed prematurely.
Why it's wrong here
A track delay postpones state changes, so it would keep the backup route withdrawn longer, not install it early. It is tempting because delay tuning affects convergence timing, but premature installation stems from the track object returning up when the probe should be down.
