300-710 SNCF Integration Practice Question
An enterprise integrates Cisco Secure Firewall Management Center with Cisco ISE via pxGrid. The security team wants to ensure that when an administrator quarantines a host in Cisco SecureX, the firewall immediately drops active connections from that host without waiting for the FMC policy deployment cycle. How does SecureX achieve immediate enforcement on FTD?
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
✓
SecureX uses the FMC REST API to dynamically push runtime block instructions that take effect immediately without requiring a full policy deployment.
When an immediate mitigation action (such as blocking an IP or domain) is triggered from SecureX, SecureX utilizes the FMC REST API to dynamically inject a transient block or update Security Intelligence runtime blacklists on the FTD data plane instantly, bypassing the lengthy full policy deployment cycle.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SecureX sends an SNMP set command directly to the FTD data interface kernel.
Why it's wrong here
SNMP set commands are not used for real-time threat containment on FTD.
- ✗
ISE forces the FTD to reboot into maintenance mode to clear active states.
Why it's wrong here
Rebooting firewalls for threat containment would cause a severe network outage.
- ✗
The FTD polls the SecureX cloud API every 1 second, causing high CPU usage.
Why it's wrong here
FTD does not poll cloud APIs every second; FMC handles the integration.
- ✓
SecureX uses the FMC REST API to dynamically push runtime block instructions that take effect immediately without requiring a full policy deployment.
Why this is correct
SecureX leverages FMC APIs for rapid threat containment, applying runtime blocks directly to FTD without a full deployment.
