300-710 SNCF Deployment Practice Question
A security engineer is deploying a Cisco Secure Firewall Threat Defense device inline in front of a critical server farm. The goal is to inspect all incoming and outgoing traffic for intrusions without modifying the IP addressing schema of the servers. Which interface mode should be configured on the FTD device?
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
✓
Inline mode with a bypass capability
Inline mode places the firewall directly in the path of traffic, allowing it to inspect, drop, or modify packets while operating transparently or via routed configurations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Passive mode
Why it's wrong here
Passive mode only listens to a spanned/mirrored copy of traffic and cannot block packets.
- ✓
Inline mode with a bypass capability
Why this is correct
Inline mode evaluates traffic passing directly through the interface pair and can drop malicious payloads.
- ✗
SPAN mode
Why it's wrong here
SPAN refers to switch port analyzer traffic mirroring, not a firewall interface mode.
- ✗
Promiscuous mode
Why it's wrong here
Promiscuous mode is an interface setting on underlying hypervisors/OS, not an FTD interface deployment mode.
