300-710 SNCF Integration Practice Question
An administrator configures an eStreamer client script on a remote server to receive events from FMC. The script connects successfully and starts receiving events, but after a few hours, the connection drops and throws a timeout error. What is the most likely cause of this behavior?
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
✓
An intermediate firewall or stateful device closed the TCP port 8302 session due to inactivity timeout.
Firewalls or intermediate network devices along the path between the external eStreamer client and the FMC often have idle session timeouts (e.g., 30 minutes or 1 hour). If eStreamer traffic is quiet, the session times out. eStreamer keepalive configurations or firewall idle timeouts must be adjusted.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The eStreamer service on the FMC has a hard-coded 2-hour session limit for security reasons.
Why it's wrong here
eStreamer connections are designed to remain permanently open for continuous streaming.
- ✗
The FMC automatically rotates the eStreamer client certificate every 4 hours.
Why it's wrong here
eStreamer certificates do not rotate automatically every few hours.
- ✗
The Snort inspection engine on the FTD restarts hourly to clear cache.
Why it's wrong here
Snort does not restart hourly.
- ✓
An intermediate firewall or stateful device closed the TCP port 8302 session due to inactivity timeout.
Why this is correct
Stateful firewalls drop idle TCP connections if no keepalives or data are exchanged within the configured timeout window.
