XSIAM-Engineer Operations And Lifecycle Management Practice Question
An administrator is troubleshooting an issue where an endpoint agent is unable to connect to the XSIAM cloud management console, and local logs indicate certificate pinning verification failure. What is the most likely cause?
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 network security device or proxy is performing SSL decryption and re-signing traffic with an untrusted certificate.
Certificate pinning failures on endpoint agents usually indicate an SSL inspection appliance or proxy in the network is re-signing traffic with an untrusted root certificate, causing the agent to reject the connection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
An intermediate network security device or proxy is performing SSL decryption and re-signing traffic with an untrusted certificate.
Why this is correct
Correct. SSL decryption without proper CA trust installation on endpoints causes certificate pinning and verification failures.
- ✗
The Cortex XDR agent version is too new for the cloud tenant and must be downgraded.
Why it's wrong here
Incorrect. Backward compatibility is maintained; version mismatches cause registration errors, not CA pinning failures.
- ✗
The local firewall is blocking UDP port 514 outbound from the endpoint.
Why it's wrong here
Incorrect. Cortex XDR agents communicate outbound over HTTPS (port 443), not syslog (UDP 514).
- ✗
The XSIAM tenant license has expired, causing all agents to enter a permanent lock state.
Why it's wrong here
Incorrect. License expiration typically results in grace periods or data ingestion throttling, not SSL certificate verification errors.
