300-710 SNCF Integration Practice Question
An administrator is troubleshooting an eStreamer integration where custom Python client scripts fail to receive events from the FMC. The administrator verifies that network connectivity, certificates, and user permissions are correct. Upon running the client script in verbose mode, the error indicates an 'Incompatible Protocol Version' between the client SDK and the FMC. How is this resolved?
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
✓
Update the eStreamer client SDK on the third-party SIEM to a version compatible with the current FMC software release.
Cisco FMC updates frequently include eStreamer protocol version upgrades. If an older third-party SIEM client SDK is used with a newly upgraded FMC, the client SDK must be updated to match or support the eStreamer protocol version running on the FMC.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Downgrade the FMC software to match the legacy eStreamer client library.
Why it's wrong here
Downgrading production security firewalls/managers for a client script version mismatch is a poor practice; updating the client is correct.
- ✓
Update the eStreamer client SDK on the third-party SIEM to a version compatible with the current FMC software release.
Why this is correct
Client SDKs must be compatible with the FMC eStreamer server version to negotiate the protocol successfully.
- ✗
Switch from eStreamer to legacy SNMP traps.
Why it's wrong here
SNMP traps do not replace the deep connection and intrusion event streaming capabilities of eStreamer.
- ✗
Modify the eStreamer version registry key in the FMC expert shell configuration file.
Why it's wrong here
Protocol versions are hardcoded into the eStreamer binary daemons and cannot be forced via registry edits.
