300-710 SNCF Integration Practice Question
An administrator is configuring the Cisco eStreamer client on a Linux-based SIEM collector to connect to the FMC. After copying the generated certificate files to the client, the connection attempt fails with an error indicating that the client certificate is untrusted. What is the most likely reason for this failure?
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
✓
The FMC CA certificate was not installed in the client's trusted certificate store, preventing the client from trusting the FMC's server certificate.
When generating eStreamer certificates on the FMC, the administrator must download the FMC CA certificate and place it in the client's trusted certificate store so the client trusts the FMC's TLS server certificate during the handshake.
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 client script was written in Python 3 instead of Python 2.
Why it's wrong here
Modern eStreamer client SDKs support Python 3; language version does not cause TLS untrusted errors.
- ✗
The eStreamer service on the FMC must be restarted via expert mode after every certificate generation.
Why it's wrong here
Certificate generation on FMC automatically provisions the daemon without requiring manual service restarts.
- ✓
The FMC CA certificate was not installed in the client's trusted certificate store, preventing the client from trusting the FMC's server certificate.
Why this is correct
Mutual TLS requires both client-to-server and server-to-client trust; the client must trust the FMC's CA certificate.
- ✗
The FMC management interface IP address changed, invalidating the eStreamer database index.
Why it's wrong here
IP changes affect routing, but untrusted certificate errors are purely PKI validation failures.
