300-710 SNCF Integration Practice Question
An administrator configures pxGrid integration between Cisco ISE and Cisco Secure Firewall Threat Defense. During the certificate enrollment process, the firewall fails to trust the ISE pxGrid node. What is the most likely root cause of this failure in a standalone FMC deployment?
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 ISE pxGrid root CA certificate is not imported into the FMC trusted certificates store.
For pxGrid communication to establish successfully, the ISE pxGrid node certificate and FMC/Firewall pxGrid certificate must be signed by a mutually trusted Certificate Authority (CA), and the CA root certificate must be imported into the FMC trusted certificates store.
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 SXP secret password does not match between ISE and the firewall.
Why it's wrong here
SXP uses a shared secret, but pxGrid uses mutual TLS certificate authentication, not an SXP password.
- ✗
The pxGrid subscriber profile on ISE was not approved within 24 hours.
Why it's wrong here
ISE requires manual approval of pxGrid clients, but approval status prevents session establishment after trust is built, not the initial trust handshake.
- ✓
The ISE pxGrid root CA certificate is not imported into the FMC trusted certificates store.
Why this is correct
Mutual TLS authentication requires the root CA of the peer to be present in the trusted certificate store of the validating device.
- ✗
RADIUS shared secrets are mismatched on the Policy Service Nodes.
Why it's wrong here
RADIUS is distinct from pxGrid certificate exchange.
