300-710 SNCF Deployment Practice Question
An organization is planning to deploy a Cisco Secure Firewall Threat Defense Cluster using three Secure Firewall 9300 security modules to handle a massive aggregate throughput requirement. Which consideration is critical when designing this cluster?
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
✓
All security modules in the cluster must be identical in model, memory, and interface module composition.
In a firewall cluster, one unit is automatically elected as the control node, while the others act as data nodes. All units share a common configuration and distributed connection table, but session handling is managed across the cluster nodes via a central cluster control link.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
All security modules in the cluster must be identical in model, memory, and interface module composition.
Why this is correct
Clustering requires uniform hardware models and matching interface configurations across all cluster members.
- ✗
Cluster nodes can be spread across different geographical data centers over high-latency WAN links.
Why it's wrong here
Cluster control links require low latency and high speed, typically restricting clusters to a single data center or site.
- ✗
The control node processes all data traffic while data nodes only handle control plane heartbeats.
Why it's wrong here
The control node manages control plane and configuration, while data nodes actively process data traffic alongside the control node.
- ✗
Clustering requires transparent mode; routed mode is unsupported on clustered Secure Firewall platforms.
Why it's wrong here
Clustering supports both routed and transparent modes.
