300-710 SNCF Deployment Practice Question
An administrator is preparing to deploy Cisco Secure Firewall Threat Defense in passive NGIPS mode connected to a Catalyst switch. Which TWO configuration steps on the switch and firewall are necessary for successful packet inspection? (Choose two)
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
✓
Configure the firewall data interfaces to operate in passive mode so they do not attempt to forward or drop traffic.
Passive mode requires configuring a SPAN session (or TAP) on the switch to mirror traffic and configuring passive interfaces on the FTD to ingest and inspect that mirrored stream.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure the firewall data interfaces to operate in passive mode so they do not attempt to forward or drop traffic.
Why this is correct
Passive interfaces analyze traffic without forwarding or dropping.
- ✗
Enable dynamic OSPF routing between the switch and the firewall's passive interface.
Why it's wrong here
Passive interfaces do not run routing protocols.
- ✓
Configure a SPAN (Switched Port Analyzer) or RSPAN session on the upstream switch to mirror traffic toward the firewall's passive interface.
Why this is correct
SPAN mirrors traffic to the passive firewall interface.
- ✗
Assign a default gateway IP address to the passive interface to route return packets back to clients.
Why it's wrong here
Passive interfaces do not route traffic or use default gateways.
- ✗
Configure an inline set pairing the passive interfaces with a hardware bypass module.
Why it's wrong here
Inline sets are distinct from passive interfaces.
