300-710 SNCF Deployment Practice Question
An engineer is deploying an NGIPS inline set across two physical interfaces. To prevent network disruption during maintenance, the engineer needs to ensure that if the firewall loses power or experiences a kernel panic, traffic can still traverse the physical link. Which hardware feature must the interfaces support?
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
✓
Hardware bypass capability (fail-open)
Optical or copper bypass capability (hardware fail-open/fail-close bypass caps) allows traffic to pass physically through the ports when power is lost or the system crashes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Unidirectional Link Detection (UDLD)
Why it's wrong here
UDLD detects unidirectional fiber links, but does not provide hardware power-loss bypass.
- ✗
Spanning Tree PortFast BPDU filtering
Why it's wrong here
PortFast is a switch feature to speed up convergence, not a firewall hardware bypass mechanism.
- ✗
Dynamic ARP Inspection (DAI)
Why it's wrong here
DAI mitigates ARP spoofing attacks on switches, not power-loss hardware bypass.
- ✓
Hardware bypass capability (fail-open)
Why this is correct
Hardware bypass ports physically bridge the RX/TX paths when power or software fails, allowing uninspected traffic to pass.
