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
✓
Outbound TCP connection on port 8305 from the FTD to the manager's IP address or registration FQDN.
Managed devices initiate outbound secure communication (typically over TCP port 8305 / sftunnel) to the management platform (FMC or CDO).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
An active SNMPv3 trap receiver configured on the manager pointing to the FTD.
Why it's wrong here
SNMP is not used for device registration or management tunneling.
- ✗
Inbound SSH access from the management platform IP address to the firewall management interface.
Why it's wrong here
Management communication uses sftunnel over TCP 8305, initiated outbound from the FTD.
- ✗
An IPSec site-to-site VPN tunnel terminating on the data interfaces.
Why it's wrong here
Registration occurs via the management interface, not via data-plane IPSec VPNs.
- ✓
Outbound TCP connection on port 8305 from the FTD to the manager's IP address or registration FQDN.
Why this is correct
The FTD device establishes an outbound secure tunnel (sftunnel) on TCP 8305 to the management platform.
