300-710 SNCF Integration Practice Question
An organization configures third-party SIEM integration where Secure Firewall Threat Defense sends syslog messages over UDP. During high-traffic events, the SIEM administrator notices significant log dropping and packet loss across the network. What is the best practice solution to ensure reliable syslog delivery without packet loss due to UDP buffer overflows?
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
✓
Configure Reliable Syslog utilizing TCP transport to ensure flow control and guaranteed packet delivery.
UDP is a best-effort transport protocol prone to packet loss during network congestion. Switching to Reliable Syslog (TCP with TLS encryption) ensures flow control, retransmissions, and guaranteed delivery of syslog messages to the SIEM.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure Reliable Syslog utilizing TCP transport to ensure flow control and guaranteed packet delivery.
Why this is correct
TCP provides retransmission and flow control, eliminating the packet loss issues inherent to UDP syslog in high-traffic environments.
- ✗
Increase the UDP socket buffer size on the FTD expert shell using sysctl kernel tuning.
Why it's wrong here
Modifying internal kernel sysctl parameters on FTD is unsupported and does not solve network-level UDP drop issues.
- ✗
Disable connection logging and rely solely on eStreamer.
Why it's wrong here
Disabling logging defeats the purpose of SIEM log ingestion.
- ✗
Configure NAT overload on the syslog export interface.
Why it's wrong here
NAT affects IP routing, not transport layer reliability or buffer loss.
