300-710 SNCF Deployment Practice Question
An engineer is configuring static route tracking on a Cisco Secure Firewall Threat Defense to ensure high availability for outbound internet connectivity. A backup static route is configured with a higher metric. What mechanism does the firewall use to dynamically switch from the primary route to the backup route when the primary next-hop fails?
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
✓
Bidirectional Forwarding Detection (BFD) or ICMP ping SLA trackers that monitor the next-hop IP.
Static route tracking utilizes Embedded Event Manager (EEM) or IP SLA monitoring (via ICMP/TCP probes) to track reachability, modifying the routing table dynamically when the probe fails.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Bidirectional Forwarding Detection (BFD) or ICMP ping SLA trackers that monitor the next-hop IP.
Why this is correct
Static route tracking relies on IP SLA (ping/TCP monitors) or BFD to monitor availability and remove the primary route from the forwarding table upon failure.
- ✗
STP topology change notifications received on the tracked interface.
Why it's wrong here
STP operates at Layer 2 and does not track Layer 3 next-hop IP reachability.
- ✗
FMC heartbeat loss detection between the firewall and the gateway.
Why it's wrong here
FMC heartbeats are for management connectivity, not real-time data plane route tracking.
- ✗
Automatic generation of dynamic OSPF neighbor adjacencies over the static interface.
Why it's wrong here
Static route tracking does not require or use OSPF adjacencies.
