300-710 SNCF Deployment Practice Question
An administrator is configuring inline interface pairs on a Cisco Secure Firewall Threat Defense device. Which THREE characteristics apply to inline deployment mode? (Choose three)
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
✓
Asymmetric routing must be carefully managed or avoided because inline inspection expects to see both directions of a TCP flow.
Inline mode inspects traffic live, can drop packets based on policy or threats, and supports hardware bypass (fail-open) capabilities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Inline interfaces require SPAN or TAP configurations on upstream core switches to receive mirrored traffic copies.
Why it's wrong here
SPAN/TAP is used for passive mode, not inline mode.
- ✓
Asymmetric routing must be carefully managed or avoided because inline inspection expects to see both directions of a TCP flow.
Why this is correct
Inline inspection requires seeing both forward and return paths for stateful analysis.
- ✓
Inline sets can be configured with hardware bypass (Fail Open) settings to maintain network connectivity if the device loses power.
Why this is correct
Hardware bypass allows traffic to flow even if power fails.
- ✓
The firewall sits directly in the traffic path, allowing it to inspect and drop malicious packets before they reach destination hosts.
Why this is correct
Inline mode permits active inspection and dropping of traffic.
- ✗
Inline mode prevents the firewall from operating in routed mode.
Why it's wrong here
Inline interfaces can be deployed within routed mode architectures.
