Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

✓
The firewall operates as a Layer 2 bridge, forwarding frames based on destination MAC addresses.
Transparent mode bridges traffic across interfaces in a bridge group using BVIs, acting as a stealth firewall at Layer 2.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Every interface in transparent mode must have a unique Layer 3 subnet IP address for routing.
Why it's wrong here
Transparent mode interfaces do not require unique Layer 3 subnets; they belong to the bridge group.
- ✗
NAT is fully unsupported across all transparent firewall deployments.
Why it's wrong here
NAT (specifically EtherType and basic NAT rules) is supported in transparent mode.
- ✓
The firewall operates as a Layer 2 bridge, forwarding frames based on destination MAC addresses.
Why this is correct
Transparent mode performs Layer 2 bridging.
- ✓
Bridge Virtual Interfaces (BVIs) are assigned IP addresses to allow management access and gateway functionality.
Why this is correct
BVIs have management IP addresses in transparent mode.
- ✗
Dynamic routing protocols like OSPF and EIGRP are fully supported on BVI interfaces.
Why it's wrong here
Dynamic routing protocols are not supported on BVIs in transparent mode.
