300-710 SNCF Deployment Practice Question
An administrator configures a Cisco Secure Firewall Threat Defense cluster. During normal operations, a data node experiences a critical hardware failure. What happens to the active connections currently processed by that specific failed data node?
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
✓
Active connections are migrated or maintained by surviving cluster nodes because connection state is distributed across the cluster.
In a firewall cluster, connection states are shared or can be redistributed/failed over. When a data node fails, existing connections handled by that node are re-hashed or terminated unless state is synchronized across the cluster nodes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Active connections are migrated or maintained by surviving cluster nodes because connection state is distributed across the cluster.
Why this is correct
Clustered devices share connection state information, allowing surviving nodes to absorb and maintain active flows upon node failure.
- ✗
Traffic destined for the failed node is permanently blackholed until the physical module is replaced.
Why it's wrong here
Cluster load balancing algorithms and master node routing adjust flow distribution away from the failed module.
- ✗
All active connections are immediately dropped, forcing clients to re-establish TCP handshakes from scratch.
Why it's wrong here
Cluster architecture synchronizes connection state information so surviving nodes can take over connections seamlessly.
- ✗
The entire cluster reboots to elect a new control node and rebuild the data plane.
Why it's wrong here
A data node failure does not trigger a cluster-wide reboot.
