300-710 SNCF Deployment Practice Question
You are deploying a Cisco Secure Firewall Threat Defense in an existing core network as an out-of-band intrusion prevention system. Which NGIPS deployment mode should you configure to ensure the firewall performs deep packet inspection and generates alerts without dropping any production traffic in the event of a device failure or high load?
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
✓
Passive deployment mode using a SPAN or tap source
Passive mode listens to a mirrored traffic stream (e.g., via SPAN or TAP). It analyzes copies of packets and cannot drop live production traffic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Transparent mode with inline bypass enabled
Why it's wrong here
Transparent mode is a firewall forwarding mode, not an out-of-band inspection mode.
- ✗
Inline deployment mode with fail-open enabled
Why it's wrong here
Inline mode sits physically in the path; even with fail-open, it acts as a bridge during normal operations.
- ✗
Routed mode with asymmetric routing tolerance
Why it's wrong here
Routed mode is an active Layer 3 forwarding mode.
- ✓
Passive deployment mode using a SPAN or tap source
Why this is correct
Passive mode receives mirrored traffic via SPAN/TAP and operates entirely out-of-band without interfering with the live traffic path.
