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
✓
Configuring a management IP address on a management interface or BVI (Bridge Virtual Interface) for device access
In transparent mode, the firewall acts like a bridge, requiring bridge group interfaces and management IP addresses for administration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Assigning Layer 3 IP addresses to every data interface participating in packet routing
Why it's wrong here
Transparent firewalls do not route packets at Layer 3 across data interfaces; they bridge them at Layer 2.
- ✗
Configuring dynamic BGP peering on all client-facing ports
Why it's wrong here
BGP routing is used in Layer 3 routed topologies.
- ✗
Removing all security rules since Layer 2 devices cannot filter traffic
Why it's wrong here
Transparent firewalls still enforce security rules and inspection policies.
- ✓
Configuring a management IP address on a management interface or BVI (Bridge Virtual Interface) for device access
Why this is correct
A management IP is needed to administer the firewall remotely.
- ✓
Placing the bridged interfaces into a common bridge group or zone
Why this is correct
Bridged interfaces are grouped together to forward frames across the segment.
