An architect is troubleshooting a Cortex XDR deployment where agents on endpoints are failing to communicate with the Cortex XDR cloud tenant. Which outbound network connectivity requirement must be verified on the local corporate firewall?
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
✓
Outbound TCP port 443 (HTTPS) access to the Cortex XDR tenant cloud URL.
Cortex XDR agents communicate with the cloud tenant over outbound HTTPS (TCP port 443).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Outbound TCP port 443 (HTTPS) access to the Cortex XDR tenant cloud URL.
Why this is correct
Cortex XDR agents require outbound HTTPS (port 443) access to communicate with the cloud backend.
- ✗
Inbound UDP port 69 (TFTP) from endpoints to Panorama.
Why it's wrong here
TFTP is not used by Cortex XDR agents.
- ✗
Inbound TCP port 3389 (RDP) from the cloud backend to every endpoint.
Why it's wrong here
Inbound RDP is insecure and not required by XDR.
- ✗
Outbound TCP port 3978 to Panorama Collectors.
Why it's wrong here
Port 3978 is for Panorama log collection from firewalls, not XDR agents.
