300-710 SNCF Deployment Practice Question
An engineer is deploying Cisco Secure Firewall Threat Defense in a complex multi-zone routed environment. Which THREE design considerations apply when implementing routed mode interfaces? (Choose three)
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
✓
Each routed interface must belong to a distinct IP subnet and act as a Layer 3 gateway for connected segments.
Routed mode interfaces require IP addresses, participate in routing protocols or static routes, and handle MAC address rewriting as Layer 3 gateways.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
NAT configuration is strictly prohibited on routed mode interfaces.
Why it's wrong here
NAT is fully supported and commonly used on routed interfaces.
- ✓
Each routed interface must belong to a distinct IP subnet and act as a Layer 3 gateway for connected segments.
Why this is correct
Routed interfaces operate at Layer 3 with IP addresses.
- ✗
All physical interfaces must be combined into a single Bridge Virtual Interface (BVI).
Why it's wrong here
BVI is used in transparent mode, not routed mode.
- ✓
The firewall rewrites source and destination MAC addresses as traffic passes between routed interfaces.
Why this is correct
Layer 3 routing operations rewrite MAC addresses at each hop.
- ✓
Dynamic routing protocols such as OSPF and BGP can be configured on these interfaces.
Why this is correct
Routed mode supports OSPF and BGP routing protocols.

Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
