Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The network requires advanced NAT, PAT, and dynamic routing protocols like OSPF and BGP.
Why it's wrong here
NAT and dynamic routing protocols require routed mode.
- ✓
The firewall needs to be inserted into an existing IP subnet without altering current gateway or routing designs.
Why this is correct
Transparent mode acts as a stealth bridge, allowing insertion without redesigning network IP schemas.
- ✗
The deployment requires termination of site-to-site IPsec VPN tunnels.
Why it's wrong here
IPsec VPN termination is fully supported in routed mode.
- ✗
The firewall must act as the default gateway for multiple VLAN segments.
Why it's wrong here
Acting as a default gateway is a Layer 3 routed mode function.
